Journal Article 1992

Autor: Rege, J.E.O. Lomole, M.A. Wakhungu, Judi W.

Investigates the effects of non genetic factors on performance, and estimates genetic parameters of reproductive and productive traits with a view to examining the appropriateness of the assumed parameters. Presents an evaluation of a long-term breeding programme in a closed Sahiwal herd in Keny...

Journal Article 1992

Autor: Rege, J.E.O. Wakhungu, Judi W.

Analyses trends in genetic and environemntal components of performance, to estimate levels of inbreeding and to quantify its effects on performance in order to identify which of these factors is responsible for the decline in performance at the Stud. Presents an evaluation of long-term breeding p...

Journal Article 1993

Autor: Thorpe, W.R. Kang'ethe, P. Rege, J.E.O. Mosi, R.O. Mwandotto, B.A.J. Njuguna, P.

Individual and maternal additive genetic and heterotic effects were estimated for preweaning, reproductive, and lactation traits of the Sahiwal breed and its crosses with Bos taurus (Ayrshire and Friesian). The individual additive genetic breed effect influenced all cow traits except annual milk ...

Conference Paper 1991

Autor: Rege, J.E.O. Wakhungu, Judi W. Lamole, M.A.

Estimates genetic parameters and trends in reproductive and productive traits of Sahiwal cattle - milk yield, birth weight of calves, service period, number of services per conception and calving interval, from records covering the period 1964 through 1988 obtained from the Kenya Sahiwal Stud, Na...
