A study was conducted at the Asella Station in the Arsi Region of Ethiopia to investigate the dairy performance of indigenous purebred Arsi and Friesian X Arsi crosses under different pre-partum and post-partum supplementary feeding regimes. A total of 343 first-lactation animals were involved in...

The season of calving affected calving interval, weaner weight per cow per year, dam weights at mating, parturition and weaning, and dam weight changes during gestation and lactation. The year of calving influenced calving interval, calf survival, weaner weight per 100 kg of cow weight per year, ...

We report for the first time, and for the whole of sub-Saharan Africa, the geographical distribution and the frequency of an indicine and a taurine Y specific allele amongst African cattle breeds. A total of 984 males from 69 indigenous African populations from 22 countries were analysed at the m...

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 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 (...
