Thirty-two herds of West African Dwarf goats raised under village conditions and which grazed stylosanthes (Stylosanthes hamata cVerano) or natural pasture in the wet season were monitored for 30 months to determine herd productivity. Average litter size was 1.67 (+ or -) 0.082, kidding interval ...

A total of 179 heifers, primiparous and multiparous Boran cows were assigned to four breeding units and mated over a 4 - month breeidng season in a single-sire mating system. Mean body weight and body condition scores at the beginning of mating ranged from 363 + 6 kg to 388 + 7 kg and from 6.7 + ...

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...

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...

This study was conducted in the central highlands of Ethiopia during 1990-92 to examine the effects of diet and partial suckling on lactation and reproductive performance of Boran (Bos indicus) cows. Primiparous Boran cows were allocated to dietary supplementation or no supplementation with eithe...

In 1988 and 1989, the effects of endoparasites on reproductive performance of on-farm sheep were studied at 5 sites in the Ethiopian highlands using nematode eggs per gram (EPG) counts, treamatode EPG and packed-cell volume (PCV). Mean litter size, lambing interval, annual reproductive rate and a...

This paper discusses the single-round survey of smallholder goat and sheep production which is carried out in the Nigerian sub-humid-zone villages. In order to determine and analyse the importance of the designing and executing surveys as well as to give emphasis upon the flock breed structure ex...

Production performance of cows is an important factor which determines whether cows are adopted for draft power. Working cows could perform at higher levels of efficiency than oxen, but only if nutrient inputs are adequate to meet their greater requirements, and milk production and reproduction a...
