荷斯坦牛头胎产奶量的遗传分析
Genetic Analysis of Fetal Milk Yield of Holstein Cow
摘要
Abstract
Objective]Through the estimation of Hutubi Holstein cattle farm first 305 days milk yield of genetic parameters and breeding value,this paper aims to set up the genetic evaluation system and evaluate the advantages and disadvantages of the genetic evaluation system and the evaluation of the breeding bulls.[Meth-od]The milk yield of Xinjiang Hutubi cattle farm 1 ,145 Holstein dairy cow fetal and pedigree data were used for SAS software statistical analysis.The effects of 4 factors:the field,calving year,calving month and the primip-arous month age on milk yield were observed to study the seasonal variation of milk yield in 305 days.And mo-reover,the heritability and breeding value of milk yield in 305 days were estimated by BLUPf90 program.[Re-sult]Pasture,calving year and calving month affected 305 day milk yield significantly (P<0.01 ),effects of primiparous months on 305 day milk yield were not significant (P>0.05 );The milk yield changed significantly with the change of the seasons.In winter and spring,milk yield was higher than other seasons.The heritability of milk production was 0.268.The estimated breeding value of each individual and ancestor was obtained and the scope was 1,967.04 to -1,042.78.The difference was 3,009.82 kg.[Conclusion]In this dairy herd,Ani-mal genetic gap were larger,the individual genetic ability were better,to provide a reliable scientific basis for se-lection accuracy and improved efficiency for reference for the rational organization of dairy production and im-prove.关键词
