Techniques of surgical and non-surgical ova collection of superovulated cows.

A comparison is made of the results of ova collection from 65 superovulated cows of varying ages using the conventional surgical technique and a non-surgical (transcervical) technique. Two types of apparatus, rigid and flexible, were developed for non-surgical collections. The problems associated with these techniques are discussed and some remedial measures suggested. A mean of 9.8 ova per donor cow were recovered by the surgical method compared to 2.9 and 3.0 ova recovered by the transcervical method using flexible and rigid apparatus respectively. Eight young cows, which had not been previosly subjected to superovulation and embryo collection, yielded an average of 5.6 ova per donor by the non-surgical technique.

Serological studies in the elderly.

Sera from 108 elderly patients in psychiatric and general hospitals were tested for antibodies to seven viruses. Measles virus antibody levels were significantly higher in patients from the psychiatric hospital, regardless of diagnosis, than in those from other hospitals. Demented patients, regardless of their hospital, had significantly higher levels of antibody to adenovirus than control patients.

Preparation of teaser bulls by dorsal scrotal penile deflection.

A simple, quick and reliable technique of preparing teaser bulls has been developed. Four Bos indicus aged between 1 year 6 months and 2 years were subjected to this method by deflecting their penes backwards about 2 to 3 cm posterior and dorsal to the attachment of the scrotum. No serious postoperative complications were recorded. The sexual behaviour and libido of the bulls did not change after subjecting them to this technique.

Successful transfer of a bovine embryo through a cannulated fallopian tube.

The fallopian tubes of a recipient cow were surgically cannulated and the cannulae brought out through the flank. Two fertilised eggs, recovered surgically from a donor cow, were transferred to the uterus of the recipient cow through the cannulae. The recipient became pregnant and gave birth to a live normal female calf 289 days after the transfer. After the birth of the calf one cannula was found to be patent.

Another style of psychogeriatric service.

This paper describes a psychogeriatric service in Gloucestershire. Agreement on policies was reached with general practitioners, Social Services, other psychiatrists and hospital nursing staff. The day hospital is regarded as the preferred area of treatment for a wide variety of patients, including the severely demented. In this service less than five per cent of admissions appear to become long-stay. With emphasis on day hospital and community support the number of beds for this type of patient recommended by DHSS may be excessive.

Transcervical transfer of bovine embryos.

Six-to nine-day-old embryos collected either surgically or nonsurgically from superovulated donor cows were transferred transcervically to recipient cows. Polyethylene tubes and plastic insemination pipettes were used to transfer the embryos. When embryos were transferred under controlled conditions (laboratory transfer) to 12 recipients, 10 (83.3 per cent) and eight (66.7 per cent) were tested pregnant at 45 and 90 days after transfer respectively. When transfers were made to 12 recipients under field conditions (paddock transfer), nine (75 per cent) and five (41.7 per cent) were tested pregnant at 45 and 90 days after transfer respectively. The difference in pregnancy rates between laboratory and paddock transfers was not statistically significant.
