Conference Paper 1992

Autor: Inyangala, B.A.O. Rege, J.E.O. Itulya, S.

Presents results of a study undertaken at Magogo, Kenya, to analyse genetic and phenotypic correlations between adjacent weights, between weights and rates of growth, and among growth rates themselves, hence data on 969 lambs collected over a 10-year period (1978-1987) on Dorper sheep were used i...

Autor: Rege, J.E.O. Lipner, M.E.

Addresses different papers presented on the workshop organised by ILCA, as part of the research planning process on a project of characterisation, conservation and utilization of Africa's indigenous animal genetic resources. In taking on this challenging task, ILCA recognised that it could not su...

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 1991

Autor: Rege, J.E.O.

An original data set of 31, 661 lactation records of Kenyan Friesian cows covering the period 1968 through 1987 was used to develop part-lactation extension factors for milk yield, and to estimate genetic parameters for production and reproductive traits. Effects of herds and year were significan...

Autor: Rege, J.E.O.

The Kenya Livestock Recording Centre progeny testing data base covering the period 1968 through 1987 was used to estimate genetic and phenotypic trends in Friesian cattle for milk yield of all lactations, first lactation milk yield, age at first calving, and calving interval. Annual genetic and p...

Genetic parameters for birth and 240-day weaning weights in Gudali and Wakwa cattle breeds in a tropical environment in Cameroon were estimated by derivative-free restricted maximum likelihood procedure using single-trait animal models with maternal effects. Performance data covered the period 19...
