A study conducted to evaluate seasonality in the reproductive status of Ethiopian highland sheep using slaughter animals.
Presents results of a study conducted to assess the extent to which incubation time, temperature or failure to separate plasma soon after collection influence the plasma progesterone concentration in Ethiopian indigenous 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...
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 ...
A study undertaken to characterise the oestrous cycle in Zebu cows following oestrous induction with PGF (Prostaglandin F2alpha) and examines the function of the subsequently formed CL (corpus luteum) by monitoring levels of peripheral plasma progesterone.
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.
The productive performance of indigenous sheep and goats of Ethiopia were evaluated over a period of 2 years (October 1979 to March 1981). Data on age at first parturition, litter size, lambing and kidding intervals, annual reproductive rates, mortality rates and growth rates included.
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...
