STUDY ON FITTING MATHEMATICAL MODELS OF LACTATIONCURVE IN BLACK AND WHITE CATTLE IN GUANG ZHOU AREA

Wang Qian,Lin Ling(Guangzhou Dairy Cattle Institute,Guangzhou 510405)Lin Jisheng(Guangdong Applied Meteorologic Institute)  
Milk prduction records from 113 Holstein lactations cows in Guangzhou area were calculated on time us-ing 3 mathematical models. The models included Wood function model.polynomial medel and regression medel.Above three medels are not optimal in Guangzhou area, Therefore, one new modlfied polynomial medel Y=k_0+k_1t+k_2t ̄2+k_3lnt+k_4ln ̄2t+k_5e ̄(-137.5/t)was drawed.Supplemental e ̄(-137.5/t) is modlification milk production of middle and lat-ter time.Using the new model fitting showed relatlve error10%in 80%samples,absolute error500 kg,muliplecorrelation coefficient0.9.All samples were P0.01 significant levels.
