Genetic 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 کاملGenetic 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 کاملGenome-Wide Association Study for Wool Production Traits in a Chinese Merino Sheep Population
Genome-wide association studies (GWAS) provide a powerful approach for identifying quantitative trait loci without prior knowledge of location or function. To identify loci associated with wool production traits, we performed a genome-wide association study on a total of 765 Chinese Merino sheep (JunKen type) genotyped with 50 K single nucleotide polymorphisms (SNPs). In the present study, five...
متن کاملGenetic 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 کاملPolymorphisms of FST gene and their association with wool quality traits in Chinese Merino sheep
Follistatin (FST) is involved in hair follicle morphogenesis. However, its effects on hair traits are not clear. This study was designed to investigate the effects of FST gene single nucleotide polymorphisms (SNP) on wool quality traits in Chinese Merino sheep (Junken Type). We performed gene expression analysis, SNP detection, and association analysis of FST gene with sheep wool quality traits...
