摘要
为探究新疆石河子地区牛奶脂蛋比(FPR)与奶牛繁殖性能的相关性,本研究统计分析了石河子垦区奶牛2019年1月-2020年9月间的牛奶脂蛋比数据,通过曲线估计确定了脂蛋比(FPR)与配妊率(PR)具有线性和二次项关系,但差异不显著,从R方数值看,二次曲线的拟合程度好于线性,FPR过高和过低,均导致PR降低。
In order to explore the correlation between milk fat-pro ratio(FPR)of Xinjiang Shihezi and the reproductive performance of dairy cattle,the paper statistically analyzed the milk fat-pro ratio data from 201901 to 202009 in Shihezi reclamation area,and determined that FPR and PR in Shihezi area had linear and quadratic relationship through curve estimation,but the difference was not significant,the fitting degree of quadratic curve is better than that of linear curve.Too high and too low FPR can lead to the decreasing of PR.
