肉用鸡的累积生长与饲料报酬耦合模型研究

Study on the couple of accumulative growth and feed efficiency in broiler

根据肉用鸡的生长曲线提出了与其相耦合的饲料报酬模型ｘ１（ｔ）＝，（ａ＞０，ｂ＞０）或ｘ２（ｔ）＝（ａ＞０，ｂ＜０，ｃ＞０），据此模型可估计出与速生区间基本吻合的饲料报酬高效区间。

Two models that describe feed conversion efficiency were studied to couple with the growth curve of broiler , (a>0,b<0,c>0). The results indicated that the models could predict the phase of the better benefit of feeding chicken and its proper slaughter weeks of age.
