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, ...

Purebred Menz and first cross (50%) Awassi x Menz and 75% Awassi cross sheep were bred and reared under common environmental and management conditions. Mean birth and 120-day weaning weights recorded from 10 lambings were 2.4, 3.0, and 3.8 kg (p<0.001) and 15.6, 17.6, and 21.5 kg (P<0.001) for Me...

Purebred Menz, first cross (50%) Awassi x Menz, and second cross (75%) Awassi x Menz sheep were bred and reared under common environmental and management conditions. Reproductive data and mature body weights were recorded over a 6-year period between 1982 and 1987. Over all genotypes and years, t...

Purebred Menz, first-cross Awassi x Menz, and first-cross Corriedale x Menz lambs were born and reared together under common environmental and management conditions. Before they reached six months of age, animals of each sex in each genotype were allocated to two treatment groups. Both groups gra...

Mortality was studied in relation to birth weight (BWT) and postpartum age in 3083 Horro lambs born over 15 years at Bako Research Center, IAR. Pre-weaning mortality rose with declining BWT (log y = 2.20- 0.35X; r = 0.9981), but the influence after weaning was less pronounced and linear (y = 23.7...

After a preliminary common lambing, Horro ewes were mated either twice at 12-month intervals or three times at 8-month intervals over a period of two years. There were no significant differences between the two mating systems in their productivity at each lambing. However, ewes in the 8-monthly s...

Genetic and environmental factors affecting performance of Adal sheep are investigated. Birth records of 723 Adal lambs at Melka Werer research station were analysed to determine effects on birth, weaning, 6-month and yearling weights and post-weaning daily gain. Year, sex and type of birth had h...

The study included two trials, each of two phases, to investigate the feasibility of finishing Adal lambs on irrigated pasture and the effect of concentrate supplementation. Fifty-one ram lambs with initial mean weight of 11.9 kg and mean age of 18 week were used in phase 1 Trail 1 while phase 2 ...

Analyzes mating/parturition records on Ethiopian sheep and goat breeds, to study the effect of the duration of mating season on flock fertility, with emphasis on data related to cumulative percentage of females conceiving at different intervals of the mating season.
