Horse Breeding Show Jumping Variance Components
2016/5/18
Fifty 3-month-old male Tan lambs (similar in body weight) were divided into 5 groups to investigate the effects of different restricted pasture grazing times and indoor supplementation on the producti...
Multiple Genes Related to Muscle Identified through a Joint Analysis of a Two-stage Genome-wide Association Study for Racing Performance of 1,156 Thoroughbreds
Single Nucleotide Polymorphism Estimated Breeding Value
2016/5/18
Thoroughbred, a relatively recent horse breed, is best known for its use in horse racing. Although myostatin (MSTN) variants have been reported to be highly associated with horse racing performance, t...
Polymorphism Identification, RH Mapping and Association of Lactalbumin Gene with Milk Performance Traits in Chinese Holstein
Lactalbumin SNP Milk Performance Traits RH Mapping Chinese Holstein
2016/4/26
Lactose synthase catalyses the formation of lactose which is the major osmole of bovine milk and regulates the milk volume. Alpha-lactalbumin (??LA) is involved in the synthesis of lactose synthase in...
Association between SNPs within Prolactin Gene and Milk Performance Traits in Holstein Dairy Cattle
Holstein Dairy Cattle Prolactinx Prolactin Haplotype SNPs Milk Performance Traits
2016/4/22
Prolactin plays an important role in mammary gland development, milk section initiation and maintenance of lactation, so the bovine prolactin gene is considered as a potential quantitative trait locus...
