3个品种黄羽肉鸡生长模型比较研究
Comparative Study on Growth Models of Three Different Breeds of Yellow-Feathered Broilers
摘要
Abstract
The aim of this experiment was to compare the growth and development rules and genetic param-eters of three different breeds of yellow-feathered broilers by Logistic,Gompertz and Richards nonlinear mathematical models.A total of 240 1-day-old Bearded chickens,Guangxi chickens and Qingyuan chick-ens were randomly divided into 3 groups(6 replicates per group and 40 chickens per replicate).The yellow-feathered broilers in each group were fed diets with the same nutritional level until 100 days of age,and the experiment lasted for 100 days.The results showed as follows:① body weight increased with age,the body weight of Bearded chickens>Guangxi chickens>Qingyuan chickens.②Among the three growth models,Richards curve model had the highest degree of fit and was more superior in estimating body weight of Bearded chickens,Guangxi chickens and Qingyuan chickens.According to Richards growth model,the inflection point body weight of Bearded,Guangxi and Qingyuan chickens was 1 696.21 g,1 428.70 g and 789.94 g,respectively.The turning point age was 92.39 d,81.65 d and 61.35 d,respectively.关键词
