摘要
Abstract
To investigate the effects of high-quality frozen semen and conventional frozen semen on the production performance of dairy cows,this study selected lactating cows from a large-scale dairy farm as the experimental population.Efficient reproductive technologies including estrous synchronization and fixed-time artificial insemination were systematically applied,and genetic testing was used to evaluate the improvement effects of female calves in terms of production performance and body conformation traits.The results showed that the total body conformation score,limb and hoof structure score,comprehensive udder score,and locomotion score of female calves in the experimental group(high-quality frozen semen group)were significantly higher than those in the control group(conventional frozen semen group)by 1.49,0.6,1.17,and 0.63,respectively(P<0.05).The chest depth and body depth of female calves in the experimental group were improved compared with the control group,but the differences were not significant(P＞0.05).In addition,the productive life,Integrated Performance Index(IPI)of the iGenome,milk yield,and net benefit of the experimental group were significantly higher than those of the control group by 2.18 months,595.09,597.98 kg,and 513.12 dollars,respectively(P<0.05).The findings indicated that the application of high-quality frozen semen not only significantly improved the body conformation traits,milk production performance and productive life of dairy cows,but also enhanced their economic benefit level and sustainable development capacity.关键词
