Studies 42 household units in two ecological zones of four farming villages located in the heart of Kumawu Traditional Area (KTA) in Asante, Ghana. The traditional area is the largest (9,256 sq. km) of the 21 traditional areas or paramouncies comprising the Kumawu, which is located 56 km north-ea...

The influence of age and parturition interval of West African Dwarf (WAD) ewes on birth weight, serum immunoglobin (Ig) concentration and mortality rates in the neonatal lambs were examined. Age of ewe significantly influenced birth weight of lambs with effect being more pronounced on twin lambs (P

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...

PCR-SSCP and DNA sequencing approaches were applied to assess the single nucleotide polymorphisms (SNPs) and analyze the genetic polymorphisms at partial exon 2 and intron 2 of H-FABP(Heart fatty acid-binding protein)gene, and five sheep populations that comprised of Small-Tailed Han sheep (SH, 4...

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...
