The experiments reported here were specifically designed to compare in tropical sheep and goats the digestibility, energy and nitrogen utilization of silages and silage plus concentrate under identical environmental conditions. In addition, growth trials were also conducted. The first trial utili...

The effects of age of ewe, and year, sex, and year, sex and type of birth of lambs on lamb weights between birth and weaning were measured and appropriate correction factors estimated in a flock of east African Blackhead sheep maintained over an 11-year period in Western Uganda. These correction ...

Forty-eight West African Dwarf sheep and goats (twenty-four each) averaging 11 kg body weight and 8 months of age, were alloted in groups of eight to six rations containing 0%, 15%, 30%, 45%, 60% and 75% brewers' dried grain (BDG) which were fed ad libitum together with 0.5kg/head/day fresh forag...

Genetic parameters were estimated for birth-, 42-day, and 100-day (weaning) weight in the Dorper flock of the Glen Agricultural Institute in South Africa. Direct habitability estimates of 0.11, 0.28 and 0.20 and maternal habitability estimates of 0.10, 0.10 and 0.10 were obtained for body weight ...
Two trials were performed to study the fattening performance of Ethiopian highland sheep under feed-lot conditions. Three diets were tried; A-20 % hay, B -35% hay and C-50% hay. Trial I had the three diets represented on 84 non-descript highland all-milk-tooth ram lambs, while in Trial II, only, ...

Total of 8909 birth weight and 7740 weaning weight records, from the progeny of 215 sires, collected from 1943 to 1990 from the Elsenburg Dormer sheep stud, were analysed. Additive genetic variance and heritability estimates for birth weight (BW), weaning weight (WW), average daily gain (ADG) and...

Dorset Horn rams were used on East African Blackhead sheep in western Uganda in mutton production through improved lamb growth. The crossbred lambs were significantly heavier than the indigenous at birth. From birth to weaning at five months, the growth rates of both types were identical, being 0...
