巴马小型猪早期生长曲线拟合研究
Study on curves fitting Bama miniature pigs'early-stage growth
摘要
Abstract
The average weekly body weight of 32 Bama miniature pigs randomly selected from 4 litters was measured during 0-25 weeks, and their growth curve was fitted by both logistic and Gompatz models. The results showed that their growth curve could be well fitted by both logistic mod-el(R2 =0. 997) and Gompatz model (R2 = 0. 999), and the prediction by the Gompatz model-fitted growth curve better approached the actual value. The Gompatz model-predicted inflexion point of Bama miniature pigs'early-stage growth curve was 18 weeks in age and 14.388 kg in body weight.关键词
