Plasma progesterone concentrations were determined every 10 days for 38 grazing Menz ewe lambs from weaning until conception. Lambs were either fed extra supplementry concentrates and/or drenched for endoparasites. Inadequate nutrition delayed puberty onset by 4 to 5 months. Progesterone concentr...

Small East African Zebu cows which calved during the dry season were used to determine the effects of postpartum nutritional supplementation and suckling intensity on body weight, body condition score, reproductive performance and on calf mortality and preweaning growth performance. Cows were all...

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...

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...

Describes a method for determining the sex and milk protein genotypes (RELPs) of preimplantation stage bovine embryos using multiplex polymerase chain reaction (PCR). Tests a procedure developed for diagnosing multiple characteristics by genotyping K-casein and B-lactoglobulin in addition to iden...

Many efforts to increase milk and meat production by importing temperate breeds into the tropics are constrained by the breeds' lack of adaptation to tropical diseases, biologic and present management stresses. Moreover, feeding regimes developed for temperate breeds also do not suit animals indi...

Although the importance of bull reproduction in enhancing genetic progress and influencing cow herd fertility has long been recognized in many parts of the world, there has been very little attention paid to bulls in Ethiopia. Proper management of young bulls aims to improve growth rate so that t...

The efficiency of cattle breeding and production depends to a large extent on the reproductive performance of the herd, with the bull playing a major role. Large differences in fertilizing ability between bulls exists, and such differences are due to the characteristics of individual bulls rather...

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...
