Factors affecting the early growth and survival of indigenous Ethiopian Horro sheep were identified and the influence of each was assessed, based on data collected from 1978 97 from 4031 lambs at Bako Research Centre, Ethiopia. Year of birth, sex, type of birth or rearing, and parity had signific...

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

Effects of age at weaning on growth and mortality of 6-month-old Horro lambs, born in a 12-day period, were studied. Approximately equal group of lambs were weaned at 2,3,4,5, or 6 months of age. Growth and mortality records up to 6 months of age were take.
