Journal Article 1980

Autor: Thorpe, W.R. Cruickshank, D.K.R. Thompson, R.

Carcass characters for 365 male castrated cattle of the Africander, Angoni, Barotse and Boran breeds, and the reciprocal crossbreds of the latter three were reported. In each of the two year-of-birth groups, different slaughter-age/management regimes were used. For all carcass characters except t...

Dam reproductive performance of purebred Africander, Angoni, Barotse and Boran, and reciprocal crossbreds of the latter 3 breeds under ranching conditions were investigated. Mean performance based on a maximum of 1996 records collected over six parities were: calving rate, 65.6%; weaning weight r...

Autor: Mackinnon, M.J. Thorpe, W.R. Baker, R.L.

Crossbreeding parameters and variance components were estimated for lactation and reproductive traits of crosses between the Sahiwal, Brown Swiss and Ayrshire breeds in a dairy herd in sub-humid coastal Kenya. An individual animal model was fitted to the data with a fixed effect for 20 distinct b...

Autor: Thorpe, W.R. Morris, C.A. Kang'ethe, P.

Records from 1577 cows borm from 1973 to 1983 on a ranch in lowland Kenya were analyzed for age at first calving, lactation length, lactational milk yield, calving interval, annual milk yield, and, for cows born from 1973 to 1979, number of calvings, productive lifetime in the herd, and lifetime ...

Autor: Kahi, A.K. Mackinnon, M.J. Thorpe, W.R. Baker, R.L. Njubi, D.

A total of 1443 records were used to estimate individual and maternal additive genetic breed and heterotic effects for preweaning growth and survival traits of crosses of Ayrshire (A), Brown Swiss (B), and Sahiwal (S) in a dairy herd in the lowland coastal tropics of Kenya. Individual and matern...

Autor: Baker, R.L. Mwamachi, D.M. Audho, James O. Aduda, Eric O. Thorpe, W.R.

Resistance to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Haemonchus contortus) was studied in 166 Red Maasai; 230 Dorper and 294 crossbred (Red Maasai X Dorper) ewes in the sub-humid coastal region of Kenya. Live weights (LWT), blood packed-cell volume (...

Presents results of a study carried out in three locations in the Mombasa region along the Kenyan coast on haemonchosis in lambs. In the study, purebred Dorper and Maasai-Dorper F1 cross lambs were observed for their reaction to helminth infestation and the effects of anthelmintic treatment and s...
