大别山牛母牛生长发育规律研究
|
摘要
[目的]研究大别山牛母牛体重与体尺性状之间的关系,探明大别山牛母牛的生长发育规律。[方法]分别测定3月龄、6月龄、12月龄、24月龄、36月龄和48月龄共291头大别山母牛的体重和体尺性状,利用Duncan’s法对各阶段母牛体重和体尺性状进行多重比较,检验差异显著性。利用Biraviate相关检验测成年母牛体尺体重的相关性。选用非线性Logistic模型拟合大别山牛体重的累积生长过程。[结果]表明大别山牛母牛在36月龄前体重处于快速增长阶段。成年大别山母牛体重与体斜长呈极显著相关(P<0.05),与体高等8项指标呈及显著相关(P<0.01),其中与胸围相关程度最高。大别山母牛生长的非线性Logistic方程为y=309.466/(1+4.556e~(-0.115t)),拐点体重为154.73kg,拐点月龄为13.2月龄。
[Objective]The aim of this study was to study the relationship between body weight and body measurements traits as well as to explore the growth and development pattern in Dabieshan cow.[Method]A total of 291 Dabieshan cows were selected,including 3-month old,6-month old,12-month old,24-month old,36-month old and 48-month old cows,respectively.Body weight and body size traits of selected cows were measured.Duncan's method was used to compare the body weight and body size traits of cows at various stages,as well as to test whether the significant differences were found in different groups.Moreover,Biraviate correlation was used to analyze the correlation between body size and body weight,and the nonlinear Logistic model was used to fit the cumulative growth process of body weight.[Results]The results showed that the body weight of Dabieshan cows was increasing rapidly before36-month old.Importantly,the body weight was significantly correlated with body length(P<0.05)as well as the body high and other traits(P<0.01),especially in the chest circumference.The nonlinear Logistic model of Dabieshan cows was y=309.466/(1+4.556e-0.115t),and the body weight inflexion was154.73 kg as well as the age was 13.2months.
