Random Regression Models Using Legendre Polynomials to Estimate Genetic Parameters for Test-day Milk Protein Yields in Iranian Holstein Dairy Cattle
Holstein Dairy Cattle Milk Protein Yields Random Regression Model Test-day Records
2016/12/28
The objective of this study was to estimate the genetic parameters of milk protein yields in Iranian Holstein dairy cattle. A total of 1,112,082 test-day milk protein yield records of 167,269 first la...
Investigations on Genetic Architecture of Hairy Loci in Dairy Cattle by Using Single and Whole Genome Regression Approaches

摘要
利用PCR技术和复合电泳银染技术检测奶牛和肉牛BM2113、BM1862、BMc701、BM2934、TGLA122、BM720等6个STR基因座的多态性分布，并计算该6个基因座的基因频率（Pi）、个体鉴别力（DP）、杂合度（H）、多态信息含量（PIC）、和非父排除概率（PE）。结果显示：6个STR基因座的基因型分布符合Hardy-Weinberg平衡，奶牛中6个STR基因座中BM2113...
