Variance components and genetic parameters were estimated for growth traits: birth weight (BWT), weaning weight (WWT), six-month weight (6MWT) and yearling weight (YWT) in indigenous Ethiopian Horro lambs using the Average Information REML (AIREML). Four different models: Sire model (Model 1),...

Conception, lambing rate and litter size were studied on data from a flock of Horro sheep in Ethiopia from 1878 to 1997. The CATMOD and GLM procedures of SAS were used for the analysis of these traits. A sire, direct additive genetic and a repeatability animal model were employed to obtain estim...
