朝鲜鹌鹑的生长发育性能研究

Study on Growth Performance of Korean Quail

选择300只10日龄的朝鲜鹌鹑(公、母各半),在相同的饲养管理条件下饲养4周,系统测定了各周的体重和体斜长、胸骨长、胸宽、胸深、胫长等体尺指标,并拟合了公、母鹑体重的Logistic生长曲线。结果表明,朝鲜鹌鹑公、母鹑38日龄体重为109.38 g和117.92 g,母鹑的生长速度明显高于公鹑,所拟合的公、母鹑体重的生长曲线方程分别为yt=122.5/[1+e-0.1200×(t-20.0921)](R2=0.9914)和yt=134.5/[1+e-0.1154×(t-21.0727)](R2=0.9933),鹑群生长发育均匀整齐。

300 10 - day - old Korean quails （ half male and half female） had been raised for 4 weeks under the same feeding conditions. Body weight and body size indexes including body length, sternum length, chest width, tibia length etc. were measured weekly, moreover, Logistic growth curve was fitted for body weight of male and female quails. The results demonstrated that 38 - day - old body weights of male and female Korean quail were 109.38 g and 117.92 g, respectively, female quail grew faster than male quail, body weight growth curve equations of male and female quail were yt = 122.5/[ 1 ＋ e^-0.1200×（t-20.0921）] （ R^2 = 0.9914 ） and yt = 134.5/ [ 1 ＋e^-10.1154×（t-21.0727） ] （ R^2 = 0. 9933 ） respectively, quails grew uniformly.
