七彩山鸡早期生长发育的研究

本试验对七彩山鸡011周龄的胫长和体重的生长规律进行了研究，并探讨了公母分养与公母混养及四种密度不同的饲养管理方式下，胫长和体重的生长规律。结果表明，体增重、胫增长的趋势与其它同类研究结果相似，但体增重的高峰推迟了三周左右出现，分析为前几代未进行系统选育所致．对胫长、体重的相关分析表明，除与出壳相关的项目外，其余周龄间均呈高度相关，胫长各周龄间的相关高于体重．胫长与体重间也呈高度相关。公母分养有利胫长和体重的生长，并产生极显著效果，体重的效果稍大于胫长．不同密度的饲养对胫长和体重的生长产生不同的效果，并且，对体重的影响其差异达到显著水平．

EARLY GROWTH AND DEVELOPMENT OF THE SEVENCOLOURED PHEASANT

This paper reports on the growth of the slin length and the bodyweight of the seven-coloured pheasant from the age of zero to eleven weeds. Theeffects of two feeding regimes (I. e. mixed and separated raising of male andfemale chickling) and four densities of stocking have been observed. The resultsindicate that the body weight gain and the slin length increase model of the birdis similar to that of other studies, but the peak of body weight appears aboutthree weeds later in that non-systematical selection has been done in the preced-ing generations. The shin length and the body weight at each week of age, exceptthose at hatching, are highly correlated, and the correlation of the slin lengthis higher than that of the body weight. The shin and the body weights are alsohighly correlated the separated raising of male and female chickling couldcontribute a lot to the increase of the shin length and the body weight, and theeffect of which on the body weight is slightly highter than that on the shinlength. The shin length and the body weight increase faster in low density ofstocking, and the difference of weight reaches the significant level.
