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),...

Variance components and estimates of genetic parameters for early growth traits in Horro sheep
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 reproductive performance and estimates of genetic parameters of litter size in Horro sheep
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...

Genetic parameter estimates for growth traits in Horro sheep
A total of 147 Menz and Horro lambs of both sexes were serially slaughtered and dissected at five different stages of growth to define the pattern of growth and partitioning of fat among body depots in indigenous Ethiopian Menz and Horro sheep breeds. The GLM procedure of SAS and allometric growt...

Patterns of growth and partitioning of fat depots in tropical fat-tailed Menz and Horro sheep breeds
A total of 146 Menz and Horro lambs of both sexes were serially slaughtered and dissected at 5 different stages of growth (i.e. at 1, 3, 6, 9 and 12 months of age) to define the pattern of growth and partitioning of fat among body depots of indigenous Ethiopian Menz and Horro sheep breeds. The GL...
