Chemical composition of the pearl grey guinea fowl.

1. The growth of the chemical components of the body of the Pearl Grey guinea fowl from hatching till 127 days of age was evaluated in this study. 2. The Gompertz equation is suitable to describe the growth of the different chemical components over time. 3. Body and feather fat, respectively, were estimated by subtracting the predicted weights of all other components from those of body and feather weights. This leads to an overestimation of body fat content, and erroneous estimated values for feather fat.

A comparative study between mature ostriches (Struthio camelus) and adult cockerels with regard to the true and apparent digestibilities of amino acids.

1. A study was conducted to compare apparent and true digestibility of amino acids in a high protein experimental diet between young ostriches (7 months of age) and cockerels. 2. A mean value for true digestibility of amino acids (TAAD) of 0.837 +/- 0.0073 (range 0.780 to 0.862) was derived for ostriches, compared with a mean value of 0.795 +/- 0.0258 (range 0.723 to 0.825) for cockerels. 3. True retention of dietary protein was 0.646 +/- 0.0114 and 0.609 +/- 0.0643 for ostriches and cockerels respectively. 4. Results in the present study produced evidence that the method for determining metabolisable energy values of ingredients for ostriches is also suitable for measuring the digestibility of amino acids. 5. It was concluded that accurate diet formulation for ostriches requires the assessment of amino acid digestibilities for individual ingredients, because values derived from poultry would underestimate digestibilities for ostriches.

Growth rate of different sexes of the European quail (Coturnix coturnix).

1. The Gompertz equation was used to described the growth of the European quail (Coturnix coturnix) from hatching until 107 d of age. 2. Differences (P< 0.05) in growth existed between sexes. Mature mass values of 148.0 +/- 3.00 and 191.9 +/- 5.35 g respectively were found for males and females. Males reached maximum growth at 13.4 +/- 0.33 d while a value of 16.4 +/- 0.46 d was found for females. 3. A plateau in daily food intake was reached when the time of mature mass was approached.

Carcase and component yields of rheas.

1. Three Greater Rheas (Rhea americana) and 5 Lesser Rheas (Pterocnemia pennata) were slaughtered, using the procedures conventional for ostriches in South Africa, in order to determine the expected yield of by-products and saleable lean meat, fat and bone of rheas. 2. Differences (P < 0.05) between species were found in the proportional weight of the wings, feet, skin and liver. The wings, feet and head of rheas form a higher proportion of the carcase than in ostriches, whereas the skin of the former represents a lower percentage of body weight. 3. Lean meat production from rheas (64% on a carcase weight basis) is in the same order as for ostriches, broilers, turkeys and beef.

[Hypertriglyceridemia and plasma insulin in combined familial hyperlipidemia].

UNLABELLED: Changes in insulin secretion were investigated in a group of non obese subjects with combined familial hyperlipidemia (CFH), with normal glucose tolerance, relating the observed changes with plasma triglycerides and lipoprotein phenotype. MATERIALS AND METHODS: The study was conducted with 21 subjects (16 males and 5 females; mean age: 45.9 +/- 9.1 years), diagnosed of CFH after the clinical and analytical study of patients and their first degree relatives (9 with phenotype IIa, 8 IIb, and 4 IV) and 21 healthy control subjects, of similar age, sex and body weight. In both groups, lipids, plasma lipoproteins, glucose, basal plasma insulin, and insulin after and oral glucose overload (OGO) were quantitated. RESULTS: Diastolic blood pressure was higher (p < 0.01) in CFH group compared with controls (means: 132/80 vs 123/71 mmHg, respectively). TC, TG and Apo B were also higher in the CFH group. With OGO significantly higher serum insulin levels were observed at 0, 30, 60, 90 and 120 minutes in CFH subjects compared with control group. Basal serum insulin and the area under the curve of insulin secretion after OGO was higher in subjects with triglycerides (45,579 +/- 13,056 in controls, 61,385 +/- 22,254 in CFH IIa, 70,645 +/- 17,271 IIb and 124,884 +/- 36,944 in CFH IV. Insulin secretion correlated significantly (p < 0.01) with plasma triglycerides. As conclusion, hyperinsulinism is a finding in CFH non obese subjects and with normal glucose tolerance, and has an increasing frequency in subjects with high triglycerides levels.

Children of a transsexual father: a successful intervention.

Following gender reassignment, transsexuals are often assessed in many different areas with regard to how they are functioning. However, there is little attention paid to the children they may have had prior to the operation and change in lifestyle. Children may present with problems related to the parents transsexualism, or with more generalised difficulties secondary to break-up of the family. A family of a transsexual father is described in which the children presented with difficulties and in which the intervention was successful.

The psychiatric, psychological and behavioural functioning of a boy with terminal deletion of the long arm of chromosome 10.

The developmental and behavioural functioning of a six-year-old boy with deletion of the long arm of chromosome 10 was evaluated using reliable, standardised, psychological inventories. The information obtained clarified his complex pattern of strengths and needs; it also contributes scientifically derived data to the literature on behavioural correlates of this condition.

Young people and drinking: results of an English national survey.

An account is presented of a survey of self-reported drinking habits and beliefs about alcohol amongst a national sample of teenagers in England. Fieldwork was conducted during 1988 and 1989 and involved 27 systematically selected state secondary (high) schools. Respondents were virtually all aged 14-16. The majority of teenagers reported drinking only moderate amounts of alcohol. Even so, a third of the males and nearly a fifth of the females reported having at some time consumed the equivalent of five and a half pints of beer on a single occasion. Factual knowledge about alcohol was not high and more than half of the study group supported a reduction in the legal minimum age at which alcohol may be purchased in licensed premises.

Alcohol consumption, cigarette sales and mortality in the United Kingdom: an analysis of the period 1970-1985.

This paper examines official published statistics for various causes of death in the United Kingdom between 1970 and 1985. The variables selected were mainly those that had been linked to alcohol or cigarette use. In particular, changes in mortality due to acute myocardial infarction, cancer of trachea, bronchus and lung, cirrhosis of the liver and 'alcoholism' were found to be associated with each other. Changes in all of these were highly associated with changes in both alcohol consumption and cigarette sales. For most of the causes of death examined, correlations were higher for changes in the current year than they were for lagged data. Thus even chronic disorders related to prolonged heavy alcohol or tobacco use appear to be influenced rapidly by shifts in general levels of drinking and smoking.
