A study conducted to evaluate seasonality in the reproductive status of Ethiopian highland sheep using slaughter animals.
This study was undertaken using 48 mature Menz ewes (3-6 years of age) and averaging 31.5 (standard deviation (SD)=4.9) kg body weight, to evaluate oestrus synchronization, conception and lambing rates after ram introduction following a period of isolation (n=24) or constant exposure to vasectomi...
Measures the duration of the post-partum anoestrus interval of fifty Ethiopian Menz ewes maintained on pasture grazing with uncontrolled mating; describes their associated blood progesterone patterns; and assesses their reproductive potential.
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...
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 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)...
Examines the effect of four levels of nutrition (poor, low, medium, and high) with or without endoparasitic treatment (drenching) on postweaning growth, survival and onset of puberty in Menz ewe lambs. A concentrate mixture providing 2.5 Mcal/kg dry matter (DM) metabolizable energy and 15.2 g/kg ...
