Breeding programmes for Wakwa and Ngaundere Gudali cattle breeds were initiated in Wakwa (Cameroon) in 1952 and 1965, respectively, to improve growth performance of the indigenous breedsAnimals were selected on 240-day weaning weight (WWT). Data analysed covered the period 1971 through 1985 and c...

Genetic evaluation of birth and weaning weight of Gudali and two-breed synthetic Wakwa beef cattle populations under selection in Cameroon: Genetic and phenotypic trends
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...

Mineral and crude protein content of natural pastures of the Adamawa Highlands of Cameroon were studied over a 12-month period. Samples of predominantly grazed graminae of these pastures were collected from basaltic and granitic soil types and analyzed for calcium (Ca), phosphorus (P) magnesium (...

The reproduction of Gudali and Wakwa cattle are investigated. Reproduction data on Gudali and Wakwa cattle on Adamawa Plateau from 1967 to 1988 were analysed. Age at first calving was not affected by breed, year of birth and season of calving (P>.05). Mean calving interval (536.9 ± 17.3 days) wa...

Data for this study consisted of birth weight and 240-day weaning weight records of Ngaundere Gudali calves obtained from a selection experiment conducted at the Animal Production and Extension Farm on the Adamawa highlands of Cameroon and covered the period from 1971 through 1985. Direct heritab...
