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...

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...

The effect of environmental factors on preweaning survival rate of Arsi-Bale and Borana kids at the Adami Tulu Agricultural Research Center, was investigated. Data collected on 702 kids born between 1999 and 2003 were used to evaluate the effect of year, parity, breed type, sex, season of birth, ...

Identification of breeding objective traits pertinent to specific production environments with the involvement of target beneficiaries is crucial to the success of a breed improvement program. A choice experiment was conducted in four locations representing different production systems and agro-e...
