Whitelaw, D.D.Murray, M.[Experimental evaluation of genetic resistance to African trypanosomiasis in sheep and goats in Kenya]Experimental evaluation of genetic resistance to African trypanosomiasis in sheep and goats in Kenya

Compares the response of goats and sheep when offered increasing ad lib quantities of sorghum stover. Examines growth rate, stover offered, stover refused and stover intake vs amount offered.

Published and new data from experiments conducted in several range sites in Niger and Mali were analysed to assess wet season, dry season and year-round animal weight changes, stocking rates, forage availability, feed intake and faecal excretions of cattle, sheep and goats. Herbage availability o...

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...

Short-duration rotation grazing was compared with deferred grazing in a 3-year experiment at ICRISAT, Niger. Short-duration grazing used a mixed herd (2 steers, 4 sheep and 4 goats) and cycles of 15-21 days in the wet season and 91 days in the dry season. Wet season grazing compared high (83-126 ...

In the short term, grazing of a 40-ha fallow in the Sahel, Niger, by sheep and goats reduced the standing herbage mass in the wet season and increased its disappearance during the dry season. The effects of stocking rate (62.5 or 125 k g liveweight/ha) and the proportion of sheep in the mixture (...
