Presents the results of an abattoir study on the prevalence of larvae of T. hydatigena and Echinococcus granulosus in Ethiopian sheep.
The effects of breed (Menz and Horro), season (wet and dry), and the breed by season interaction on production and response to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Longistrongylus elongata and Trichostrongylus spp. and a small proportion of Haemonc...
The paper reports on accidental urea toxicity in lambs associated with group feeding of urea-molasses block (UMB). The feeding method, the estimated toxic dose, and the incident of toxicity are described. The clinical signs, treatment, outcome, and gross pathological findings are discussed. The d...
Part of a research project carried at Addis Ababa abattoir to study ovarian activity and gastro-intestinal parasitism in sheep.
Ewe reproduction and productivity were studied in the highlands of Ethiopia in Horro and Menz ewes mated to lamb in both the wet and dry seasons from June 1992 to May 1997. The data included a total of 4890 mating records of which 2516 were Menz ewes and 2374 Horro ewes, with 2360 matings in the ...
Weaner ewe lambs (92 + 4 days, SD) of the Ethiopian Menz breed (n=115) were used to assess the impact of level of nutrition before and after first lambing on subsequent productivity. Lambs were raised either on pasture grazing only (P) or grazing with low (L), medium (M) or high (H) levels of a c...
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...
A study was conducted to estimate heritabilities of, and genetic correlations among, body weight (WT) and testicular measurements - scrotal circumference (SC), testicular diameter (TD), testicular length (TL) and epididymal diameter (ED - in ram lambs between 6, 9 and 12 months old, and relations...
A study was conducted to investigate the effect of season on, and to estimate heritabilities of, and genetic correlations among, semen and spermatozoa characteristics and the relationship of these characteristics with measures of testicular or scrotal size in 6-, 9- and 12-month old ram lambs of ...
Discusses the progress of a research project underway at Debre Berhan ILCA station carried out to study the effect of dietary supplementation and endo-parasitic control on the reproductive and productive performance of Menz-type sheep.
