【摘要】 对693只福建兔黄毛和黑毛2个品系体重进行Logistic曲线模型拟合。结果表明:福建兔黄毛品系公母兔及黑毛品系公母兔的生长模型分别为:y=1(/1/3 679+0.007 1*0.973 1x),y=1(/1/4 197+0.006 6*0.977 8x),y=1/(1/2 830+0.003 2*0.974 3x),y=1(/1/3 290+0.003 5*0.976 7x);2个品系实际生长曲线与Logistic生长模型的拟合度均在0.925以上(P<0.01),其中以福建兔黄毛品系公兔生长模型的拟合度最高(R=0.959);福建兔黄毛品系公兔的生长拐点在120日龄,体重为1 848.2 g,成熟体重为3 696.4 g;福建兔黄毛品系母兔的生长拐点在148日龄,体重为2 099.7 g,成熟体重为4 199.4 g;福建兔黑毛品系公兔的生长拐点在89日龄,体重为1 413.7 g,成熟体重为2 827.4 g;福建兔黑毛品系母兔的生长拐点在104日龄,体重为1 651.8 g,成熟体重为3 303.6 g。更多还原

【Abstract】 693 Fujian yellow and black line rabbits were chosed to fit on Logistic models of body weight.The results showed that the buck and doe of Fujian yellow and black line rabbits adapted to following growth models:y=1/(1/3 679+0.007 1*0.973 1x),y=1/(1/4 197+0.006 6*0.977 8x),y=1/(1/2 830+0.003 2*0.974 3x),y=1/(1/3 290+0.003 5*0.976 7x),respectively.The actual growth curve and Logistic growth models of two lines were fitted above 0.925(P<0.01);the fitting degree of growth model in Fujian yellow rabbit line was the highest(R=0.959).The growth inflection point of the buck of Fujian yellow rabbit was at age of 120 d,with the weight of 1 848.2 g and mature weight of 3 696.4 g;the growth inflection point of the doe of Fujian yellow rabbit was at the age of 148 d,with the weight of 2 099.7 g and mature weight of 4 199.4 g;the growth inflection point of the buck of Fujian black rabbit was at age of 89 d,with the weight of 1 413.7 g and mature weight of 2 827.4 g;the growth inflection point of the doe of Fujian black rabbit was at age of 104 d,with the weight of 1 651.8 g and mature weight of 3 303.6 g.更多还原
