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...

Data collected on 3256 lambs born to Horro and Menz breed ewes single-sire mated to 71 rams at the International Livestock research Institute (ILRI) Debre Berhan station between September 1992 and June 1996 were analysed for rates of survival and growth from birth to weaning. A significantly lowe...

The effect of urea-molasses feed-supplement blocks (MUB) on feed utilisation and the inclusion of anthelmintic medication into the blocks at strategic times to control nematode parasites was studied in lambs grazed on low quality tropical pasture. 120 Menz ram lambs of 5-7 months of age were divi...

Ewe lambs attain puberty at 10 months and 16.9 + 0.01 kg (56 percent of mature weight) and first lamb at 15 months. Postpartum anoestrus in 76 days, lambing interval is 8.4 months and 65 percent of ewes lamb three times in 2 years with a gestation period of 149 days. Ewes cycle year-round but oes...

Formulation of cost-effective preventive control programmes for helminth infection in small ruminants should be based on sound epidemiological knowledge of the time relationship between contamination of pastures and the seasonal availability of infective larvae in a given geographic area. Epidemi...
