黄牛补料配方的研究

Study on a Supplemented Feed Formula for Cow Raising

针对淮北地区黄母牛营养状况,经过研究配制出一种补料。该补料与对照组比较,可降低母牛不孕率和死胎率;增大犊牛初生重和缩短母牛产犊间隔期;并有缩短母牛妊娠期和减少母牛一次受孕所需配种次数的趋势。表明改善黄牛营养状况,可极显著地提高其繁殖机能。

According to the nutritive status of Cows in Huaibei region,the supplement feed was made. Compared with control group,the open and still birth rate of cows decreased with these supple- ment feed fed,and initial weight of calves increased,calving interval period shortened.There were a tendency to shorten pregnancy period and decrease services for stocking.Results showed that the reproductive performance of cow increased significantly through improvement of supple- ment feed.
