Serum-gronadotrofienaktiwiteit van dragtige sebra- en perdemerries

Blood was collected from 28 zebra mares (Equus burchellia antiquorum) immediately after being shot in the .Kruger National Park. The serum was separated within two hours after collection and then stored at -15°C for later assay. Of these, thirteen selected samples were tested for gonadotrophic activity. The stage of pregnancy was determined from a foetal growth curve. Blood samples from pregnant horse mares were collected by venipuncture. Nine mares were sampled. Seven blood samples at different stages of pregnancy were collected from one mare, four from another and only one sample each from the other seven mares. The stage of pregnancy was calculated from the date of last service.http://www.jsava.co.zaam2021Production Animal Studie

Dierefisiologiese navorsing aan die Universiteit van Pretoria (1928 - 1978)

Although Physiology is one of the more basic courses of the veterinary curriculum, research of a more applied nature and with important practical implications has been carried out by members of the staff of the Department of Physiology of the Faculty of Veterinary Science over the past 50 years. Tribute has been paid to the achievements of the predecessors as well as to those of the present members of the staff. Due to the increase in the educational and administrative load caused by the larger number of students over the past few years, however, the lecturers find it more and more difficult to pay the necessary attention to their research. Post-graduate students usually contribute greatly towards research in a university department. In the Veterinary Science Faculty, however, the majority of post-graduate students study part-time for financial reasons. Whereas fulltime students contribute towards the activities of the department, part-time students do not contribute in the same way. A request is therefore made that some form of financial assistance be made available for post graduate study in the Veterinary Science Faculty. This financial assistance can be used for the employment of assistants, as in the medical Faculty, or for part-time research posts. There is an increasing demand for post-graduate veterinary education and the introduction of such appointments should prove to be of great value in future research.http://explore.up.ac.za/record=b119401
