拟合杂交肉羊生长曲线及构建60、180日龄体重校正公式研究
Study on Fitting Growth Curve of Hybrid Mutton Sheep and Constructing Weight Correction Formulas at 60 days and 180 Days of Age
摘要
Abstract
The purpose of this study is to explore the growth and development patterns of hybrid mutton sheep,healthy hybrid Nanhu sheep(Southdown sheep×Hu sheep,NH)and Taohu sheep(Dorset sheep×Hu sheep,TH)were selected as the research objects.The early growth and development rules of NH sheep and TH sheep were analyzed,and weight correction formulas for NH sheep and TH sheep at 60 days(weaning)and 180 days of age were constructed by using three nonlinear models of Logistic,Gompertz,and Von Bertalanffy in SPSS software.The results showed that all three models could fit the growth curve well,and the Von Bertalanffy nonlinear model had the best fitting degree for NH sheep and TH sheep.In the target age segment,the weight correction formula constructed for NH ewes at 60 days old(weaning)is W60 calibration(kg)=Wmeasured×18.254/[18.254+0.049 3×(Tmeasured-60)],and the weight correction formula at 180 days old is W180 calibration(kg)=Wmeasured×30.956/[30.956+0.051 5×(Tmeasured-180)].The weight correction formula for TH ewes reaching 60 days(weaning)is W60 calibration(kg)=Wmeasured×17.087/[17.087+0.043 9×(Tmeasured-60)],the weight correction formula for reaching 180 days is W180 calibration(kg)=Wmeasured×31.869/[31.869+0.093 4×(Tmeasured-180)].关键词
