Genetic Parameters in Merino Sheep GENETIC PARAMETERS FOR ULTRASOUND SCAN AND WOOL TRAITS AT YEARLING AND HOGGET AGE IN MERINO SHEEP
The Australian Merino is the most important genetic resource for the wool and the lamb and sheep meat industries of Australia. In this paper estimated genetic parameters for ultrasound scan and wool traits at yearling and hogget age are presented for Merino sheep. Results indicate that it is possible to breed Merino sheep that perform well for both ultrasound scan and wool characteristics when ...
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 کاملLamb survival in Australian Merino sheep: a genetic analysis.
Direct and maternal components of variance for lamb survival to birth, 7 d, and weaning (110 d) were estimated by REML procedures in a flock of Australian Merino sheep. A total of 14,142 lambs, the progeny of 421 sires and 3,666 dams, born between 1975 and 1983 were available for analysis. The study has produced some of the most precise estimates of genetic parameters for lamb survival in the A...
متن کاملFaecal glucocorticoid metabolites and body temperature in Australian merino ewes (Ovis aries) during summer artificial insemination (AI) program
Reproductive wastage is a key issue for sheep producers, both regionally and globally. The reproductive output of farm animals can be influenced by physiological and environmental factors. Rapid and reliable quantification of physiological stress can provide a useful tool for designing and testing on-farm management interventions to improve farm animal welfare and productivity. In this study, w...
