摘要:
用曲线方程对太湖鹅及以其为母本的4个杂交组合的仔鹅体重变化和日增重变化进行了拟合,并作出了相应的曲线图.结果:3周龄前的仔鹅生长符合指数函数方程,而3周龄后则几呈直线关系;外来良种的杂交后代日增重最高峰(6周龄)比国内种的杂交后代(7周龄)约提前一周龄,相对增重的最高峰除个别组合外均在2周龄.屠宰结果显示:8周龄的仔鹅已有10%左右的腹脂,可见仔鹅上市日龄不应是传统的10周龄,而应提前至8周龄.根据仔鹅生长发育的规律,在生产中应采取相应的饲养管理措施,即前期应提高成活率,喂足精料;后期应使仔鹅处于一正常的饲养管理环境中,以发挥其生长潜力.
Abstract:
Curve equations were fixed to the growth and the daily gain of the green geese of Taihu Goose(TT), Sichuang White Goose×Taihu Goose (ST), Zedong White Goose×ST (ZST), Rhine Goose×ST(RST), Laindaise Goose×ST(LST), and the curve figures were drawn. It was found that the growth of green geese was fitted to the exponential function equations before 3 weeks old, while it was fitted to the linear equations after 3 weeks old. The daily gain peak of offspring of RST and LST was a week earlier than that of TT, ST and ZST(6 weeks old vs 7 weeks old). The relative gain peaks were in the second week in all combinations except ZST. Slaughter result showed that about 10% of fat was ovcrstocked in belly of the grese at 8 weeks old, which indicated that the green geese might be sold at 8 weeks old but not at 10 weeks old. So the growth rule of geese pointed out that relevant measures must be taken, the survival rate being improved and complete feed being fed at carlier raising period, while full flesh fodder grass and a normal environment for green geese must be provided at latter period to bring the growth potential of geese into full play.
