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...

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...

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...

This paper reviews the work of the International Livestock Research Institute (ILRI) and traces the origin of the centre. The relevance of its programme to the West Asia and North Africa (WANA) region is outlined.

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...

The effect of birth weight on lamb survival, and the role of stage of pregnant ewe supplementation and weight gain during pregnancy, were investigated for 285 Menz ewes that lambed from 334 mated when averaging 22.8+4.6 (SD) kg body weight and 2.3+0.75 condition score. Ewes either only grazed (C)...
