Conference Paper 1998

Autor: Osafo, E.L.K. Owen, E. Ellis, R.H. Said, A.N. Gill, M. Sherington, J.

The adoption of `improved' sorghum (Sorghum bicolor (L.) Moench) genotypes (i.e. drought tolerant, high grain-yielding and bird-resistant) by farmers in Ethiopia is low (Tilahun et al., 1992). Farmers prefer local, non-bird-resistant genotypes because their drought resistance and grain and stover...

Constraints do not only occur in production systems. They also limit the support available from research and extension and they have serious consequences for human welfare in Africa and for the whole community of nations. The agricultural research agendas in sub-Saharan Africa are indicating more...

The effect of genotype, lactation and season on the periparturient rise in faecal egg counts in Ethiopian highland ewes: preliminary observations. A study was carried out at the International Livestock Research Institute (ILRI) Debre Berhan Research Station Between May 1992 and January 1995 to co...

The effect. of genotype (50% 75% and 87.50, levels of milk (2 and 3 1/day) and types of housing (Barn and Hutch) were examined using 38 Boran x Friesians crossbred calves (Bos Taurus x Bos indicus). Calves were offered supplement diet (180 g/kg CP and 100g/kg roughage) and were weaned until their...

The effect of genotype (50%, 75% and 87.50, levels of milk (2 and 3 1/day) and types of housing (Barn and Hutch) on growth and survival were examined using thirty four crossbred calves Boran x Freisian (Bos Taurus x Bos indicus). Calves had access to a complete diet supplement (180 g/kg CP and 10...

Autor: Kahi, A.K. Thorpe, W.R.

An individual animal model was fitted to data from a crossbred herd in the lowland coastal tropics of Kenya to estimated breed cross means for a total of 25 genotypes having different proportions of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) genes. These means were then regressed...

One of the alternative control strategies being advocated by scientists and goats raisers is the identification of breeds of goats that are resistant specifically to endoparasites that commonly affect existing breeds and exotic genotypes. Due to the Reported large genetic variation existing among...

This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous Reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...
