Data collected on a flock of Horro sheep at Bako research center (1978 to 1997) have been analyzed for phenotypic performance on growth and reproductive performance and mortality. Additionally genetic analyses were done to estimate genetic parameters (heritability, and genetic and phenotypic corr...

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...

An investigation was made into the phenotypic characteristics of 192 (168 female and 24 male) Bonga sheep (aged from milk teeth to 4 pairs of permanent incisors) in the Keffa zone using a multi-stage cluster sampling technique to select the sampling units, the households. Based on indicated centr...
