蜀宣花牛体重和体尺生长曲线拟合研究
Growth curve fitting of body weight and body measurements in Shuxuan cattle
摘要
Abstract
The research was performed on Shuxuan cattle to understand their growth and development patterns,491 male Sichuan Xuanhua cattle aged 6-20 months were selected.Their weight,height,body length,and chest circumference were measured monthly.Logistic,Gompertz and Von Bertalanffy models were used to fit and analyze the developmental characteristics of their the growth curves for weight and body size,and fitting equations for each indicator were established.Finally,the fitting curves of the equations were compared and analyzed with the measured values.The results showed that the Logistic model was the most suitable for fitting the changes in body weight,body length and chest circumference of Shuxuan cattle.关键词
