Small ruminants contribute significantly to meat (and sometimes milk) production in Africa and hence in meeting the current shortfall created by the fast rising human population. Flock productivity may, however, be affected by a wide range of disease problems and reproductive wastage. The impact ...

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...

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...

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...

This paper presents the results of a comparative study conducted to characterize the oestrous phenonenon in Zebu and crossbred cattle and to determine oestrus detection using both androgenized cows and entire bulls. The study was conducted at ILRI Debre Zeit Research Station during the dry season...

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...
