[Sexual behaviour among adolescents aged 16- and 18-years in Poland in 2005].

OBJECTIVES: Presentation of: frequency of sexual debut and its age among 16- and 18-year-olds; number of sexual partners and use contraception methods among sexually active adolescents. MATERIAL AND METHOD: Representative sample of adolescents aged 16 and 18 years in Poland, students of different type of high schools (N=2893; 1490 boys, 1403 girls) was used. Four questions concerning sexual behaviour were included in anonymous questionnaire and were derived from U.S. the Youth Risk Behavior Survey (YRBS). RESULTS: Among 18-year-olds 49.9% of boys and 47.3% of girls reported sexual debut with mean age 16.5 and 16.8 years respectively. 26.4% of students have had sexual intercourse at age 15 years or earlier. The frequency of sexual initiation increased with age, was higher among adolescents living in towns than in villages and was the highest among vocational school students. 26.3% of adolescents had three or more and 8,8% had six or more sexual partners. 11.1% of sexually active adolescents reported that either they or their partners had use any method of contraception during their last sexual intercourse. The most common contraception methods used was condom (it was reported by 82.9% of boys and 75.2% of girls). 41.1% of adolescents used ineffective methods: withdrawal and "natural methods". CONCLUSIONS: Approximately half of 18-year-olds started their sexual life. There is not gender differences in sexual debut frequency. The risk of unwanted pregnancy, STDs infections and other sexual and reproductive health problems is the highest among girls living in towns and students of vocational schools. The development of family planning and sexual and reproductive health services for young people in Poland is necessary.

From the contraceptive to the anthropocentric revolution (Gregory Pincus in memoriam).

The author has seen more progress in science and technology than all scientists of all preceding periods together since the dawn of history and has witnessed a number of powerful revolutions (e.g. scientific, information, postindustrial, globalization, environmental, contraceptive, reproductive health, gender equity and demographic) that have profoundly changed the world and our perception of it. The contraceptive revolution started off this irreversible process with spectacular results. By 1990, contraception had become a global lifestyle for more than 900 million couples. It also resulted in subsequent revolutions in reproductive health and gender equity in a new world with a dramatically changed population structure with fewer and fewer children and more and more elderly. These revolutions will assist humankind in the 21st century in deconstructing the deterministic world view of past centuries and replacing it with a science-driven anthropocentric world view.

The Department of Defense Birth Defects Registry: overview of a new surveillance system.

BACKGROUND: The U.S. Department of Defense (DoD) is challenged with monitoring and protecting the health and wellbeing of its service members. The growing number of women on active duty and the diverse hazardous exposures associated with military service make reproductive health issues a special concern of DoD. To address this concern, the DoD Birth Defects Registry was established at the DoD Center for Deployment Health Research located at the Naval Health Research Center, San Diego, California. METHODS: The registry captures comprehensive data on healthcare utilization to calculate the prevalence of birth defects in the children of military beneficiaries. Population-based electronic surveillance is supplemented by active case validation efforts. RESULTS: Since its establishment in 1998, the registry has captured data on more than 90,000 births that occur in military families each year. Detailed analyses, to include linking registry data with military occupational exposure data (e.g., anthrax vaccination), are underway. CONCLUSIONS: The DoD Birth Defects Registry provides important reproductive health information on the geographically dispersed military population. This program is expected to complement civilian public health programs and be especially valuable to military members and their families.

Men's experiences of vasectomy in the Brazilian Public Health Service.

BACKGROUND: Vasectomy was legalized in Brazil in 1996 and is freely available in some public health institutions. Nevertheless, the prevalence of vasectomy is less than 4.4%, demonstrating how rarely this contraceptive resource is used. The promotion of greater male involvement in reproductive health was one of the recommendations of the Cairo International Conference of Population and Development (ICPD). RESEARCH OBJECTIVE: To describe the experiences of a group of men who had had vasectomy. METHOD: The thematic oral history method was used. Twenty men vasectomized in a Sao Paolo State Health Service Clinic were interviewed. Each tape-recorded narrative was analysed through transcription, textualization, and transcreation, a process used to transform the oral history into written narrative form. From each narrative a 'vital tone' was extracted, revealing the essence of the individual experience. All the data were analysed under an inductive and interpretative process. The similarities among histories were identified, and submitted to a process of reduction in order to develop descriptive categories. RESULTS: The following descriptive categories were developed from the men's experiences: Misconceptions regarding vasectomy that were overcome after hearing positive results expressed by other men; Vasectomy was the last solution for a couple's troubles related to contraceptive methods; Satisfaction related to professional support received during the process of searching for a method and deciding upon vasectomy; Satisfaction was the main feeling expressed following vasectomy and they recommended this contraceptive method to other men; Men's behaviours towards postvasectomy control was divergent despite the professional guidance. CONCLUSIONS: An integrated public policy is required to promote male involvement in reproductive health. Family planning programmes must be meaningful socioculturally and the inclusion of men in these programmes is recommended. The use of anonymized videotaped narratives or the recruitment of the men themselves during counselling about this method would be helpful for the resolution of reservations related to vasectomy. All the interviewed men expressed satisfaction with vasectomy and this feeling was mainly based on the certainty of the preservation of sexual performance. LIMITATIONS: A third of those invited for interview did not attend.

Seeking women's voices: setting the context for women's health interventions in two rural counties in Yunnan, China.

If interventions to improve health are truly to benefit women, they must be developed from the start with a critical understanding of women's own perceptions of their health problems and needs, and how these concerns are linked to other facets of women's lives. To obtain such understanding, it is crucial for health planners to seek out women in the communities where they live, to encourage them to speak in their own voices about their health and lives, and to be genuinely committed to listening to what the women have to say. This paper presents results of focus group discussions with village women in two rural counties in Yunnan, China. The data are derived from 28 focus group discussions conducted by the Women's Reproductive Health and Development Program in Yunnan as part of a comprehensive assessment of reproductive health needs in poorer, more remote areas of the two counties. The discussions were held to ascertain what village women themselves feel to be their most pressing health problems, and how these relate to work, family, social status and their use of health services. Results show how women's health and their use of health services are rightly intertwined with their labor roles, harsh environmental conditions and oppressive poverty. Widespread breakdowns in the village-level primary health care network lead village women to express a profound lack of confidence in local health services. The findings have several implications for planning and implementation. Demands on women's scarce time need to be explicitly considered when designing health education activities and health service delivery.(ABSTRACT TRUNCATED AT 250 WORDS)

Family planning in Viet Nam: a vigorous approach.

Viet Nam, a country in transition, is vigorously implementing its population and family planning policies and plans, despite the fact that increased government expenditure for family planning only amounts to some US $0.15 per capita, far short of the minimum $0.60 required. An increased range of family planning methods will be offered to the population through a "cafeteria" approach. Genital tract infections will be reduced, as well as the incidence of abortion. Research continues on injectable and implanted contraceptives, and the use of quinacrine nonsurgical female sterilization. In the long term, a mix of imported and locally-produced contraceptives is envisaged to achieve greater sustainability. Family planning will be closely linked to economic development and poverty alleviation, with mass organizations developing family planning-linked credit, savings and income generating schemes. Pilot experience has indicated value if integrated approach linking family planning, nutrition, and parasite control. The health manpower and health services systems are being overhauled, with plans to appoint family planning focal points at commune level, linked to mobile district teams and grassroots motivators. Medical equipment, contraceptives and essential drugs for family planning and reproductive health services are in short supply at an estimated 60% of commune health stations. Both the public sector and the growing private sector will need to face the challenge of providing the population with high-quality reproductive health services and family planning options suited to individual needs and preferences.

Effects of rumen-inert fat on lactation, reproduction, and health of high producing Holstein herds.

Two hundred twenty of 443 cows freshening between June 1989 and March 1990 in five commercial Holstein herds were fed .45 kg/d of rumen-inert fat from calving until 200 DIM. Control diets were fed as TMR and contained, on average, 3.7 to 4.8% supplemental fat (DM basis). Test herds had rolling herd averages of 9300 to 13,250 kg of milk. Production of 4% FCM and milk increased 1.01 (3.3%) and 1.50 kg/d (4.6%), respectively, for primiparous cows fed additional fat. Multiparous cows from four herds demonstrated no response; multiparous cows in one herd increased production of 4% FCM by 2.88 kg/d (8.2%), milk by 2.45 kg/d (6.4%), and milk fat by .14kg/d (10.6%) in response to additional fat. An explanation of response differences among herd for multiparous cows was not possible. For primiparous and multiparous cows, increased genetic potential increased treatment response. Increased body condition score at calving influenced treatment response of multiparous cows. Thinner cows produced more milk and less milk fat in response to additional dietary fat than did fatter cows. Most reproductive indices were unaffected by treatment. Cows receiving additional fat had lower, but nonsignificantly lower, incidences of most health disorders. Responses to rumen-inert fat by cows receiving high concentrations of dietary fat were marginal and were affected by body condition score at calving and by genetic potential.

WHO principles of perinatal care: the essential antenatal, perinatal, and postpartum care course.

World Health Organization (WHO) recommendations and meta-analyses of controlled trials have concluded that inappropriate perinatal care and technology continue to be practiced widely throughout the world, despite the acceptance of evidence-based principles and care. The WHO Regional Office for Europe, in consultation with policy makers and reproductive health experts recently proposed ten "Principles of Perinatal Care," which have been endorsed by the reproductive health units of most member states. A comprehensive training program, based on the principles, is now being offered throughout the European region. This paper describes the development of the WHO principles and the WHO training course "Essential Antenatal, Perinatal and Postpartum Care." Together they provide an innovative model of evidence-based and psychosocially sensitive care for the future guidance of perinatal policy makers and caregivers worldwide.

Lack of agreement between cervicography and cytology and the effect of human papillomavirus infection and viral load.

OBJECTIVE: Cohort studies of the natural history of human papillomavirus (HPV) infection and cervical squamous intraepithelial lesions with repeated screening allow the comparison of different macroscopic and microscopic diagnostic methods. MATERIALS AND METHODS: Concurrent visual inspection using cervicography and conventional Pap cytology tests were performed during multiple visits in a cohort of women attending a maternal and child health clinic in São Paulo, Brazil. HPV infection status at the same visits was determined by polymerase chain reaction followed by typing with specific oligonucleotide probing and viral load quantification. Information on reproductive health and hygiene habits was also collected at each visit. RESULTS: Overall agreement between cervicography and cytology was low (kappa = 0.046), which increased only slightly when high oncogenic-risk HPV types (kappa = 0.120) or high viral burden (>100 copies/cell) (kappa = 0.170) was present. Analysis of reproductive health and hygiene habits revealed somewhat different risk factors for cervical lesions detected by these tests. However, presence of oncogenic HPV DNA (odds ratio = 36.0, 95% CI = 16.6-77.8) and high viral burden (odds ratio = 67.34; 95% CI = 27.1-167.0) were strongly associated with lesions detected by cytology but not by cervicography. CONCLUSIONS: Although changes in the cervix (because of age, gravidity, or hormonal effects) may influence the performance of morphology-based screening tests, the lack of agreement and the different degrees of association with HPV infection measures indicate that a visual inspection method such as cervicography may detect different cervical abnormalities relative to cytology.

Adolescents' reports of parental knowledge of adolescents' use of sexual health services and their reactions to mandated parental notification for prescription contraception.

CONTEXT: Legislation has been proposed that would mandate parental notification for adolescents younger than 18 years (minors) obtaining prescription contraception from federally funded family planning clinics. OBJECTIVE: To determine the extent to which parents are currently aware that their teenage daughters are accessing reproductive health services and how minors would react in the face of mandated parental involvement laws for prescription birth control. DESIGN, SETTING, AND PARTICIPANTS: A total of 1526 female adolescents younger than 18 years seeking reproductive health services at a national sample of 79 family planning clinics were surveyed between May 2003 and February 2004. MAIN OUTCOME MEASURES: Proportions of minor females who reported that a parent or guardian was aware that they were at the family planning clinic and, under conditions of mandated parental involvement, proportions of minors who would access prescription contraceptives at family planning clinics or engage in unsafe sex. RESULTS: Sixty percent of minors reported that a parent or guardian knew they were accessing sexual health services at the clinic. Fifty-nine percent of all adolescents would use the clinic for prescription contraception even if parental notification were mandated. This response was less common (29.5%) among adolescents whose parents were unaware of their clinic visits and more common (79%) among those whose parents were aware. Many adolescents gave more than 1 response to mandated parental involvement. Forty-six percent would use an over-the-counter method, and 18% would go to a private physician. Seven percent said that they would stop having sex as one response, but only 1% indicated this would be their only reaction. One in 5 adolescents would use no contraception or rely on withdrawal as one response to mandated notification. CONCLUSIONS: Most minor adolescent females seeking family planning services report that their parents are aware of their use of services. Most would continue to use clinic services if parental notification were mandated. However, mandated parental notification laws would likely increase risky or unsafe sexual behavior and, in turn, the incidence of adolescent pregnancy and sexually transmitted diseases.

Posttraumatic stress disorder and physical comorbidity among female children and adolescents: results from service-use data.

OBJECTIVE: In adults, posttraumatic stress disorder (PTSD) is associated with adverse health outcomes and high medical utilization and cost. PTSD is twice as common in women and is associated with increased risk for a range of diseases, chronic conditions, and reproductive-health problems. Little is known about the health effects of PTSD in children. The purpose of this study was to explore patterns of physical comorbidity in female children and adolescents with PTSD by using population data. METHODS: This study was a cross-sectional, descriptive epidemiologic case-control analysis of a Midwestern state's Medicaid eligibility and paid-claims data for girls (0-8 years old) and teens (9-17 years old). Data were from 1994-1997. All those with the PTSD diagnostic code were compared with randomly selected controls in relation to 3 sets of outcomes: (1) International Classification of Diseases, Ninth Revision (ICD-9) categories of disease; (2) chronic conditions previously associated with sexual trauma and PTSD in women; and (3) reproductive-health problems. Analyses included bivariate odds ratios (OR) and logistic-regression models that control for the extent of insurance coverage and the independent associations of victimization and psychiatric comorbidity with the 3 sets of outcomes. The mental health covariate was categorical to allow consideration of a range of severity. There were 4 categories for the young girls: neither PTSD nor depression, PTSD without depression, depression without PTSD, and PTSD + depression. For the adolescent analysis, a fifth category reflecting a "complex PTSD" was added, defined as having PTSD complicated by a dissociative disorder or borderline personality disorder diagnosis. RESULTS: There were 647 girls and 1025 adolescents with the PTSD diagnosis. Overall, PTSD was associated with adverse health outcomes in both age strata. Victimization was sometimes independently associated with adverse health outcomes, but PTSD often was a mediator, especially in the adolescent age stratum. The importance of PTSD diagnosis as a predictor of the ICD-9 categories of disease or chronic conditions seemed to increase with age. In the younger age stratum, the increased bivariate ORs of significant associations with PTSD ranged from 1.4 for digestive disorders to 3.4 for circulatory disorders. Among younger girls, PTSD diagnosis was associated with significantly greater bivariate odds for 9 of the 12 ICD-9 categories of disease but not for neoplasms, blood disorders, or respiratory disorders and with threefold increased odds for chronic fatigue. They also had 1.8 times greater odds for sexually transmitted infections, some of which could be from congenital transmission in this age group, which includes infants. In the multivariate models for the young girls, the mental health variable seemed to mediate the relationship between victimization and increased odds of infectious and parasitic diseases, endocrine/metabolic/immune disorders, circulatory diseases, skin and cutaneous tissue disorders, and having any 1 of the 5 chronic conditions. The mental health categories that were significantly associated with health outcomes varied across the conditions. There were no health outcomes in which the depression-without-PTSD category was the only one significantly associated with the outcome condition. Circulatory and musculoskeletal disorders were significantly associated with all 3 of the mental health categories. Having any 1 of the 5 chronic conditions was significantly associated only with simple PTSD (PTSD without depression). Genitourinary disorders and signs/symptoms/ill-defined conditions were significantly associated with both simple and comorbid PTSD. PTSD with comorbid depression, the most severe of the mental health categories in this younger age group, was the only category associated with the endocrine/metabolic/immune disorders and skin disorders outcomes. In the adolescent age stratum, the bivariate ORs significantly associated with PTSD ranged from 2.1 for blood disorders to 5.2 for irritable bowel syndrome. Adolescents with PTSD were nearly twice as likely to have a sexually transmitted infection and 60% more likely to have cervical dysplasia. However, their rate of pregnancy was lower (23% vs 31%), a one-fourth decreased odds. In the adolescent group, only 4 outcomes (nervous system/sense organ, digestive, and genitourinary disorders and signs/symptoms/ill-defined conditions) remained statistically significantly associated with victimization after the mental health variable was added, suggesting an additive model of risk for these outcomes but a mediating role for PTSD in relation to the majority of the health outcomes. Among the adolescent girls, the range of ORs for the ICD-9 and chronic-condition diagnoses generally increased across the categories of the mental health variable in a dose-response pattern. Compared with adolescents with neither PTSD nor depression, those with PTSD without depression had statistically significant ORs from 1.5 to 3.6. Those with depression without PTSD had statistically significant ORs from 1.9 to 4.4. The significant ORs for those with PTSD comorbid with depression were from 2.3 to 6.6, and those in the complex-PTSD category had significant ORs of between 2.5 and 14.9. Only blood disorders seemed to be more strongly associated with depression alone than with the comorbid and complex forms of PTSD. The simple-PTSD category was not significantly associated with blood disorders, chronic pelvic pain, fibromyalgia, or dysmenorrhea. Depression without PTSD was not significantly associated with chronic pelvic pain or fibromyalgia. Fibromyalgia was only significantly associated with complex PTSD. CONCLUSIONS: In young girls who receive Medicaid benefits, PTSD was associated with increased odds of a range of adverse health conditions. The pattern and odds of physical comorbidity among adolescent recipients with PTSD was nearly as extensive as that seen in adult women. Overall, the pattern observed suggests that objective disease states (eg, circulatory problems, infections) may be associated with PTSD to an extent nearly as great as that of PTSD with more subjective somatic experience of loss of wellness. Using the concepts of allostatic load and allostatic support, professionals who work with children and adolescents may be able to decrease the toll that traumatic stress takes on health even if available interventions can only be thought of as supportive and fall short of completely preventing trauma exposure or completely healing posttraumatic stress. Clinical research to extend these exploratory findings is warranted.

Pakistan's maternal and child health policy: analysis, lessons and the way forward.

An estimated 400,000 infant and 16,500 maternal deaths occur annually in Pakistan. These translate into an infant mortality rate and maternal mortality ratio that should be unacceptable to any state. Disease states including communicable diseases and reproductive health (RH) problems, which are largely preventable account for over 50% of the disease burden. The analysis of Pakistan's maternal and child health (MCH) and family planning (FP) policy covers the period 1990-2002, and focuses on macroeconomic influences, priority programs and gaps, adequacy of resources, equity and organizational aspects, and the process of policy formulation. The overall MCH/FP policy is well directed. MCH/FP has been a priority in all policies; resource allocation, although unacceptably low, has substantially increased during the last decade; and there is a progressive shift from MCH to the reproductive health (RH) agenda. Areas in need of improvement include greater use of evidence as a basis for policy; increased priority to nutrition programs, measures to reduce neonatal and perinatal mortality, provision of emergency obstetric care, availability of skilled birth attendants, and a clear policy on integrated management of childhood illnesses. Enhanced planning capacity, development of a balanced human resource, improved governance to reduce staff absenteeism and frequent transfers, and a greater role of the private sector in the provision of services are some organizational aspects that need the governments' consideration. There are several lessons to be learnt: (i) Ministries of Health need sustained stewardship and well-documented evidence to protect cuts in resource allocation; (ii) frequent policy announcement sends inappropriate signals to managers and weakens on-going implementation; (iii) MCH/FP policies unless informed by evidence and participation of interest groups are unlikely to address gaps in programs; (iv) distributional and equity objectives of MCH/FP be addressed while setting overall national goals; (v) institutional capacity is a vital ingredient in translating MCH/FP policies into effective services. The suggested strategic directions emphasize, among others, the need for a comprehensive MCH/FP framework; strengthened stewardship in ministry of health, cost-effective strategies to address the gaps identified and doubling of the public sector resource allocation to MCH/FP over the next 5 years. The ability to ensure delivery of quality health services remains the biggest challenge in the Pakistani health sector. Unless sound policies are backed by well-functioning programs they are likely to become a victim of poor implementation.

Contraceptive use by Maori youth in New Zealand: associated risk and protective factors.

AIMS: To identify risk and protective factors associated with consistent contraception use by sexually active Maori youth. METHODS: Secondary analysis was undertaken utilising Youth2000, an anonymous nationally representative secondary school health and wellbeing survey, undertaken in 2001. We describe the self-reported sexual health and contraceptive use behaviours of Maori students. A multiple logistic regression model was utilised to identify risk and protective factors associated with consistent contraception use by sexually active Maori students. RESULTS: Half of the Maori students have had sexual intercourse (54% males; 48% females) and a third are currently sexually active (33% males; 34% females). Most Maori youth who have ever had sex use condoms for contraception (82%) and most sexually active Maori youth reported consistent use of contraception (71% males; 70% females). Maori youth who use contraception consistently are more likely to report getting enough time with a parent (OR 1.50; 95% CI 1.05-2.14; p=0.03) and less likely to report weekly marijuana use (OR 0.53; 95% CI 0.37-0.76; p=0.0006). CONCLUSIONS: Consistent use of condoms is a common self-reported contraceptive practice by many young Maori. However this behaviour is not universal, and in view of the significant sexual and reproductive health disparities that exist for Maori youth, sexual and reproductive health programs should examine a broader strategy of promoting protective factors such as strengthening youth-parent relationships and reducing risk factors, such as minimising substance misuse. Together with existing efforts in education, whanau (family), and community based programs, these strategies may support healthier sexual health outcomes for Maori youth.

A client-centered approach to family planning: the Davao project.

The reproductive health approach to family planning shifts the focus of service provision from macro-level demographic objectives to meeting clients' needs. Little field experience exists to date, however, to indicate how to implement this approach. This study describes a field project in Davao del Norte and Compostela Valley provinces in the Philippines that implemented the reproductive health approach on a quasi-experimental basis. The intervention was designed to address clients' self-defined reproductive needs by providing them with relevant and accurate information and services of good quality. It consisted of two components: Providers were trained in information exchange at fixed clinics, and supervisors were trained in facilitative supervision. The results presented here indicate that the client-centered intervention was successful in enhancing service providers' knowledge and improving the content of information exchange between providers and clients. One provincial health officer has expanded the intervention throughout his province, while other provinces are interested in duplicating the model.

Boron workers in China: exploring work and lifestyle factors related to boron exposure.

This article describes the lifestyle patterns of boron mining and processing workers (N=936) and a comparison group (N=251) in northeast China, and explores relationships between boron exposure and reproductive health. An English version of an interview guide addressing areas of work and lifestyle relevant to boron exposure and metabolism was developed by an occupational health research team, translated to Chinese, and translated back, for clarity. Modifications incorporated suggestions from a local community advisory board and boron industry workers; the translation-back translation process was reapplied, and cultural and semantic equivalence was attained. Results from the interviews showed more than 64% of workers and comparison group participants smoked tobacco and more than 92% reported exposure to environmental tobacco smoke. Boron workers and the comparison group varied in their food intake and alcohol consumption, but not in their smoking habits. Thirty-four percent of boron workers reported eating in the contaminated work area. Nearly all boron workers (99%) showered or bathed after work, although approximately 10% redressed in their contaminated clothes. Reproductive health outcomes were explored, including delayed pregnancy, multiple births, spontaneous miscarriages, induced abortions, stillbirths, and an unusual ratio of male to female offspring. Implications for occupational health nurses and recommendations for future research are provided.

A review of ten years' experience with surgical equipment in international health programs.

The Johns Hopkins Program for International Education in Gynecology and Obstetrics (JHPIEGO) began in June of 1973 with financial assistance from the Agency for International Development (AID). The purpose of the organization was to provide training and medical equipment to physicians in developing countries to update their education in reproductive health. JHPIEGO began by offering courses in the United States and shortly thereafter began training at centers in the developing countries themselves. Because of its important contributions to gynecological diagnosis in addition to its use in fertility management, laparoscopic equipment has been a major item in JHPIEGO reproductive health training. This paper details the development and role of laparoscopic training in JHPIEGO's program. Laparoscopic training begins with selection of trainees from appropriate institutions. Training itself begins with a didactic session at Baltimore or an in-country center. Trainees then receive clinical training and perform a minimum number of procedures, after which the practitioner, if he or she has successfully completed the clinical practice, can be named eligible to receive medical equipment to be donated to his or her institution. When equipment is installed, a field visit is made by a JHPIEGO consultant to insure the proper use and upkeep of equipment, and the understanding and implementation of standards and procedures. JHPIEGO has trained almost 3000 physicians in laparoscopy techniques between 1973 and 1984.

Milk yield, health, and reproduction of dairy cows given somatotropin (Somavubove) beginning early postpartum.

Cows (n = 210) were assigned to the following treatments: uninjected controls through 130 d postpartum; zero to high, uninjected through 60 d then injected with 14 mg of bST/d from 61 through 130 d postpartum; low, 5 mg of bST/d from 14 through 130 d postpartum; low to high, 5 mg of bST/d from 14 through 60 d then 14 mg of BST/d from 61 through 130 d postpartum; and high, 14 mg of bST/d from 14 through 130 d postpartum. Cows given 5 mg of bST/d (low and low to high treatments) yielded 1.2 kg of FCM/d more and high group cows yielded 1.3 kg of FCM/d more than control cows between 14 and 60 d postpartum. Cows given bST yielded 2.7 to 4.1 kg of FCM/d more than control cows during 61 to 130 d postpartum. Overall, control cows yielded 35.1 kg of FCM/d, and bST-dosed cows yielded 2.2 to 3.2 kg/d more FCM. Low group cows had improved pregnancy rate (80.0%) and conception rate (82.2%) compared with high group cows (57.2 and 60.3%). Neither pregnancy (70.0%) nor conception rates (71.5%) of controls differed from other groups. However, low group cows had first service conception rate of 57.8% compared with 34.3% for high and 38.2% for low to high group cows. First postpartum estrus was observed in high group cows about 13 to 16 d later than in low and low to high group cows, whereas low group cows came into first estrus 9 d sooner than controls. Cows of high group had lower body condition than controls (2.5 vs. 2.9), but other groups did not differ (2.7 to 2.9) from controls. Health was not adversely affected. Early postpartum bST administration at 5 mg/d increases FCM and, perhaps, reproductive performance of dairy cattle compared with herdmates.
