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...

A study was carried out at the International Livestock Research Institute (ILRI) Debre Berhan Research Station in Ethiopia from 1992 to 1995 to compare the peri-parturient rise (PPR) in faecal nematode egg counts (FEC) in ewes of two indigenous sheep breeds. A total of 1439 Menz and 1347 Horro ew...

Ruminants adapt to periodic fluctuation in feed resources by accumulating fat stores during favourable periods. Thus, genetic variations, among ruminant genotypes, in the capa city to deposit fat could be exploited through breeding to improve animal productivity in traditional tropical production...

The effects of breed and dietary protein supplementation on the development of resistance and resilience to gastrointestinal nematode parasites (endoparasites) were examined in artificially infected Horro and Menz lambs from 4 to 12 months of age. The factorial design involved two breeds, two inf...

This paper discusses the research plan established to inventory and develop African breeds and protocols for In situ characterization. The paper also presents a review of West African Taurine cattle breeds. Minimum essential data set for breed characterization is summarised in a table form, and b...

The effects of breed (Menz and Horro), season (wet and dry), and the breed by season interaction on production and response to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Longistrongylus elongata and Trichostrongylus spp. and a small proportion of Haemonc...

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...

A total of 147 Menz and Horro lambs of both sexes were serially slaughtered and dissected at five different stages of growth to define the pattern of growth and partitioning of fat among body depots in indigenous Ethiopian Menz and Horro sheep breeds. The GLM procedure of SAS and allometric growt...
