Baker, R.L.Audho, James O.Aduda, Eric O.Thorpe, W.R.[Genetic resistance to gastrointestinal nematode parasites in some indigenous breeds of sheep and goats in Kenya]Genetic resistance to gastrointestinal nematode parasites in some indigenous breeds of sheep and goats in Kenya

The economic and biological efficiency of cotton seed cake (CSC) and molasses urea block (MUB) supplementation to control gastrointestinal nematode parasites was examined in artificially infected Horro and Menz lambs from 3 to 12 months of age. The factorial O.xperimental design involved 2 breeds...


Haile, AynalemBaker, R.L.Rege, J.E.O.[Economics of gastrointestinal nematode parasite control: The case of protein supplementation]Economics of gastrointestinal nematode parasite control: The case of protein supplementation

Red Maasai [Masai] and Dorper sheep were evaluated for their resistance to gastrointestinal nematode parasites (predominantly Haemonchus contortus), productivity and efficiency in experiments undertaken at the Kenyan coast (humid environment) and the Kenya highlands (semiarid environment). It was...


Baker, R.L.Mugambi, J.M.M.Audho, James O.Carles, A.B.Thorpe, W.R.[Comparison of Red Maasai and Dorper sheep for resistance to gastro-intestinal nematode parasites: Productivity and efficiency in a humid and a semi-arid environment in Kenya]Comparison of Red Maasai and Dorper sheep for resistance to gastro-intestinal nematode parasites: Productivity and efficiency in a humid and a semi-arid environment in Kenya

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...


Baker, R.L.Mwamachi, D.M.Audho, James O.Thorpe, W.R.[Genetic resistance to gastrointestinal nematode parasites in Red Maasai sheep in Kenya]Genetic resistance to gastrointestinal nematode parasites in Red Maasai sheep in Kenya

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...


Haile, AynalemTembely, S.Anindo, D.O.Rege, J.E.O.Mukasa-Mugerwa, E.Yami, A.Baker, R.L.[Genetic resistance to gastrointestinal parasites in artificially infected Horro and Menz Ethiopian sheep breeds]Genetic resistance to gastrointestinal parasites in artificially infected Horro and Menz Ethiopian sheep breeds
Autor: Baker, R.L.

The paper reviews the limited data available on both between-and within-breed genetic variation for resistance to helminthiasis in cattle, sheep and goats in the tropics. Topics covered include criteria of resistance, resilience or tolerance, parasite species and mode of infection, parameters to ...


Baker, R.L.[Genetic resistance against helminth infections in cattle, sheep and goats in the tropics]Genetic resistance against helminth infections in cattle, sheep and goats in the tropics

Research in Kenya has confirmed that Red Maasai sheep are more resistant to gastrointestinal parasites than Dorper sheep and has shown that Small East African goats are more resistant than Galla goats. There is no difference in resistance between the Menz and Horro sheep breeds in Ethiopia. Herit...

Rege, J.E.O.Baker, R.L.Hanotte, Olivier H.[Improving our understanding and utilisation of indigenous livestock breeds of developing countries: Key research challenges]Improving our understanding and utilisation of indigenous livestock breeds of developing countries: Key research challenges

The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involve mating, for each breed, 150 ewes with 10 rams to lamb at the begi...


Rege, J.E.O.Tembely, S.Mukasa, E.Sovani, S.Anindo, D.O.Lahlou-Kassi, A.Baker, R.L.[Preliminary evidence for genetic resistance to endoparasites in Menz and Horro lambs in the highlands of Ethiopia]Preliminary evidence for genetic resistance to endoparasites in Menz and Horro lambs in the highlands of Ethiopia

Sub-Saharan Africa is rich in animal biodiversity. Over 95 percent of the continent's domestic ruminants are indigenous. In Africa, indigenous livestock breeds support the majority of smallholder rural farmers for whom these genetic resources are important for improved nutrition, income and as in...
