Genetic Parameters for Body Weight, Carcass and Wool Traits in Dohne Merino
The Dohne Merino was introduced to Australia as a dual-purpose (wool and meat) breed at the end of 1990s with very limited genetic parameters available. Up to 373,639 records per trait were used to estimate genetic parameters for eight traits in this study. Heritability estimates ( ± s.e.) were 0.34 ± 0.02 for weaning weight (Wwt), 0.27 ± 0.01 for yearling weight (Ywt), 0.13 ± 0.01 for yearling...
متن کاملGenetic parameters of wool colour and skin traits in Corriedale sheep
Clean wool colour (CWC) is an important wool price determinant and has been related to suint characteristics, i.e. sudoriparous and sebaceous gland secretions, such as suint percentage and suint K content. In this work heritability, phenotypic and genetic correlations among wool colour and skin traits were examined. The genetic estimates were assessed by Restricted Maximum Likelihood (REML) pro...
متن کاملGenetic parameters among weight, prolificacy, and wool traits of Columbia, Polypay, Rambouillet, and Targhee sheep.
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,...
متن کاملGenetic Parameters in Merino Sheep GENETIC RELATIONSHIPS BETWEEN CARCASS QUALITY AND WOOL PRODUCTION TRAITS IN AUSTRALIAN MERINO RAMS
The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...
متن کاملPhenotypic and Genetic Parameters of Pre-Weaning Growth Traits in Gentile di Puglia Lambs
Data from 1731 Gentile di Puglia lambs, sired by 65 rams over a 5-year period were analyzed by a mixed model to estimate the variance components for heritability. The considered growth traits were: birth weight (BW), weight at 30 days of age (W30) and average daily gain from birth to 30 days of age (DG). Year of birth, sex of lamb, type of birth (single or twin), dam age at lambing and farm wer...
