Baker, R.L.Reynolds, L.Lahlou-Kassi, A.Rege, J.E.O.Bekele, T.Mukasa-Mugerwa, E.Rey, B.[Prospects for breeding for resistance to endoparasites in small ruminants in Africa a new ILCA research programme]Prospects for breeding for resistance to endoparasites in small ruminants in Africa a new ILCA research programme

This paper presents the results of a comparative study conducted to characterize the oestrous phenonenon in Zebu and crossbred cattle and to determine oestrus detection using both androgenized cows and entire bulls. The study was conducted at ILRI Debre Zeit Research Station during the dry season...

Many efforts to increase milk and meat production by importing temperate breeds into the tropics are constrained by the breeds' lack of adaptation to tropical diseases, biologic and present management stresses. Moreover, feeding regimes developed for temperate breeds also do not suit animals indi...

The milk and meat productivity of Ethiopia's 27 million cattle is still low for the human population of 53 million, which grows at 2.9 percent yr and is expected to surpass 65 million at the end of this century. The present cattle population includes 40 percent (10.8 million) cows of breeding age...

This work was conducted to assist the large cattle multiplication centres to produce more animals of the genotype being demanded to improve peasant farm income, to generate an alternative way of introducing the same genotype to farmers with limited income by using artificial insemination, to assi...

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 dietary protein supplementation on the resistance of lambs to endoparasites was examined in Horro and Menz lambs artificially infected with Haemonchus contortus. The experimental design involved 2 breeds, 2 infection treatments (infected Vs non-infected) and 3 nutrition treatments. ...

Although the importance of bull reproduction in enhancing genetic progress and influencing cow herd fertility has long been recognized in many parts of the world, there has been very little attention paid to bulls in Ethiopia. Proper management of young bulls aims to improve growth rate so that t...

There are many agroecological zones in sub-Saharan Africa but the pattern of animal production and the major problems associated with it do not generally vary. It is, therefore, appropriate to make a general assessment of the status, limitations and potential of animal production in sub-Saharan A...
