摘要: |
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x/t=1+b(e-ht-1)/1+at3,(a>0,b>0)或x2=a+1-a/t+1/1+bt+ct4,(a>0,b<0,c>0),根据模型可估计出与速生区间基本吻合的饲料报酬高效区间。 |

Study on the couple of accumulative growth and feed efficiency in broiler |
|
Abstract: |
Two models that describe feed conversion efficiency were studied to couple with the growth curve of broilerx/t=1+b(e-ht-1)/1+at3,(a>0,b>0),x2=a+1-a/t+1/1+bt+ct4,(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. |
Key words: growth curve feed conversion efficiency couple model |
