Study on Microsatellite Marker and Production Capacity of Steppe Red Cattle and Their Cross-bred Cattle
摘要
Abstract
To study how to produce improved Steppe Red Cattle and improve their production capac⁃ity, a total of 45 Steppe Red Cattle, cross⁃bred cattle of Steppe Red Cattle and Limousin cattle were chosen to study their weight gain. The three Loci as pl of ETH225, IDVG44 and IDVGA55 were se⁃lected, difference significance of production capacity of different labeled genes was tested, and mul⁃tiple comparison was made. The results show that covariate initial weight has great effect on weight after feeding. After eliminating the influence of the initial weight, difference ( P<0�01) of weight gain effect is significant. To further study the relationships between microsatellite markers and pro⁃duction performance, taking body measurements and body weight as indexes of growth and develop⁃ment, its meat quality was tested. Using SPSS20�0, relevance of the labeled gene and growth traits of the three microsatellite Loci as pl and meat muscle linear scale properties were analyzed. The re⁃sults show that the three microsatellite markers are correlated to the growth and development traits of the cattle.关键词
