In this study 5025 records from the Lori-Bakhtiari sheep stud were used to predict phenotypic, genetic and environmental change in ewe traits from 1989 to 2004. Best linear unbiased prediction (BLUP) of breeding values were estimated by Drivative Free Restricted Maximum Likelihood (DFREML) procedure using single and multi-trait animal model. Phenotypic, genetic and environmental trends were cal...

to study the fleece characteristics of native goats in sistan and balouchestan province, fiber sample was taken from 270 females between one to three years old from khash, saravan and iranshahr cities. the differences between age groups for all fleece parameters except fleece weight were not significant. the fleece weight of two and three years old goats were 263.4 (± 7.7) and 315 (± 7.8) gr, r...

This study was conducted to investigate the effects of age and sex on the fleece characteristics of 40 Iranian indigenous Khorasan goats. Goats were divided into two different sex and age (kids and adults) groups. Fiber characteristics under study were: fleece weight, fiber length, lock length, fiber diameter, coefficient of fiber diameter, breaking load, resistance, elongation, hair percentage...

Genetic parameters from both single-trait and bivariate analyses for prolificacy, weight, and wool traits were estimated using REML with animal models for Targhee sheep from data collected from 1950 to 1998 at the U.S. Sheep Experiment Station, Dubois, ID. Breeding values from both single-trait and seven-trait analyses calculated with the parameters estimated from the single-trait and bivariate...

Genetic parameters for Columbia, Polypay, Rambouillet, and Targhee sheep were estimated using REML with animal models for prolificacy, weight, and wool traits. All bivariate analyses included a covariance between additive genetic effects for the two traits plus appropriate additional covariances. Number of observations by breed ranged from 5,140 to 7,095 for prolificacy traits, from 7,750 to 9,...

Genetic parameters from both single-trait and bivariate analyses for prolificacy, weight and wool traits were estimated using REML with animal models for Columbia sheep from data collected from 1950 to 1998 at the U.S. Sheep Experiment Station (USSES), Dubois, ID. Breeding values from both single-trait and seven-trait analyses calculated using the parameters estimated from the single-trait and ...
