红腹锦鸡(Chrysolophus pictus)生长曲线分析

对自繁自养的21只0～163日龄红腹锦鸡(Chrysolophus pictus)的体质量mb、体长lb、跗跖长lt、翅长lw及喙长lc进行了连续测定,其中mb,lb,lw及lc的生长过程可以用Gompertz 方程很好地拟合(R>0.97),而lt用Logistic方程拟合效果更好(R=0.9886). 各量相对应生长曲线的拐点位置分别是:mb(42.95d, 220.4g), lb(5.065d, 95.59mm), lw(10.17d, 63.90mm),lt(19.89d, 43.42mm)及lc(6.903d,9.738mm);完成90%生长量的日龄分别是123.4, 89.75, 53.94, 75.47和132.4d. 根据红腹锦鸡mb的生长曲线,建议以0～6周龄为育雏期,7～18周为育成前期,19周龄至开产为育成后期.

THE GROWTH CURVE ANALYSIS OF GOLDEN PHEASANT (CHYSOLOPHUS PICTUS)

The indicators, such as body mass ( m b, g), body length ( l b, mm), wing length ( l w, mm), tarsometatarsus length ( l t, mm), and culmen length ( l c, mm) of golden pheasant ( Chysolophus pictus ) from hatching till 163 days of age, are measured. Gompertz function is suitable to describe the growth curve of m b, l b, l w, l c ( R >0.97) and Logistic function is suitable for l t ( R =0.988 6). The reflection point of each growth curve is m b(42 95 d, 220.4 g), l b (5.065 d, 95.59 mm), l w(10.17 d, 63.90 mm), l t (19.89 d, 43.42 mm) and l c (6.903 d,9.738 mm). The days of age while it completes the 90% growth mass, are 123.4 d ( m b), 89.75 d( l b), 53.94 d( l w), 75.47 d ( l t) and 132.4 d( l c) respectively. In result, it can be suggested that the stage from 0 to 6 weeks of age is the chicken period, 7 to 18 weeks is the early growing period and 19 weeks to onset of laying is the latter growing period of rearing golden pheasant.
