Reports Outline Genetic Research Study Findings from Engineering University

February 11, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Life Science Research is now available. According to news reporting originating in Shandong, People's Republic of China, by NewsRx journalists, research stated, "Prolactin (PRL) plays central roles in mammals' reproduction, gland development, milk secretion, and the expression of milk protein genes. In dairy cattle, the PRL gene is a potential quantitative trait locus and genetic marker related to milk performance traits."

The news reporters obtained a quote from the research from Engineering University, "Here, a total of 586 randomly selected Chinese Holstein cows were genotyped for locus PRL-RsaI. One haplotype block containing eight SNPs was identified in the region from intron 3 to intron 4 of the PRL gene in Chinese Holstein cows. One tag SNP (7545 G ? A) was selected to represent the haplotype block defined by the genotypic data. The cows with genotype AA of this tag SNP had a higher milk yield at 305 days (8457 938 kg) than the cows with GA (7537 1278 kg; p

According to the news reporters, the research concluded: "This suggests that the haplotype block examined in this study contains important markers for milk production traits in Chinese Holstein cows."
