| 摘 要： | 根据Logistic生长曲线方程原理确定了非洲鸵鸟生长曲线方程参数a=29.0992,b=0.4977,并对方程进行了拟合,建立了非洲鸵鸟生长曲线方程^y=K/(1 29.0992e3/0.4977x)(ry′x=3/0.9918,P<0.001)。估测出非洲鸵鸟生长终极体重为108.69kg,达到最大体重的时间为204.49 d。为今后非洲鸵鸟在我国开展选育和科学饲养、适时出栏屠宰提供了一定依据。

| Abstract: | According to the principle in the equation of Logistic curve of growth,We identified the equation''s parameter of curve of growth:a=29.0992,b=0.4977,then fitted the equation,established the equation of Africa ostrich''s curve of growth:ý=K/(1+29.0992e-0.4977x)(ry''x=-0.9918,P<0.001).The result concluded the Africa ostrich''s ultimate growth weight was 108.69kg,the time of reaching to the maximal weight was 204.49 d.It is expect to provide certain foundation for breeding selection,scientificallv breeding and slau}hterine in good time. |
