This study was undertaken to investigate the relationship between date of birth and growth performance of calves born to seasonally-bred range cows. Late born calves exhibited an apparent superiority in preweaning growth over that of their early-born counterparts. This was attributed to a positiv...

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...

Calving date (CD) records of 68896 polled Hereford dams of 120 682 calves were coded within herd-year-season with date 1 being the date the first calf was born. Factors affecting CD and its relationship with production traits were investigated. Early calving was found to be associated with high p...

The relative performance of Mashona, Nkone, Tuli (indigenous breeds), Afrikaner, all these being Sanga type, Charolais, Sussex (Bos Taurus), Brahman (Zebu) and several resultant crosses reared on range in a semi arid environment was assessed. The results showed that indigenous cattle are consider...
