A comprehensive dynamic simulation model was developed to describe a community-based breeding program for the Menz sheep population of Ethiopia. Selection of male and female animals based on their own and maternal performance was simulated. The breeding goal traits were 6-mo weight, preweaning su...

A review of genetic and environmental influences on the growth of sheep and goats in West and Central Africa shows that the effects of year, season, month, type of birth, flock, parity, ewe/ doe and breed are important. Most of the work has been on sheep. The effects of year, season and month of ...

A study was conducted to estimate heritabilities of, and genetic correlations among, body weight (WT) and testicular measurements - scrotal circumference (SC), testicular diameter (TD), testicular length (TL) and epididymal diameter (ED - in ram lambs between 6, 9 and 12 months old, and relations...

Observations were made of the ages at first appearance of each pair of permanent incisors (‘eruption age’), and the time from first appearance to full eruption of each pair (‘eruption’), for Large East African Zebu cattle (Boran). For females the eruption ages were found to be 108.5±9.9 weeks, 13...

Presents estimates of some of the phenotypic and genetic parameters of East African Zebu cattle in West Kenya with respect to milk production. Milk production data at the Baraton, Maseno and Sangalo livestock improvement centres, covering a period of twenty-five to thirty years were analysed. The...

This study was undertaken to investigate the genetic stability of an unselected Conlrol Group of South African Merino sheep and genetic change in a flock selected for increased clean fleece mass (Selection Group) under the same environmental conditions. Data regarding 14-17 months clean fleece ma...
