摘要
Two experiments were separately conducted using cottonseed cake-based diets to feed table birds. In the first experiment (phase 1) broiler birds were fed from day old to 8 weeks of age, while in the second experiment (phase 2), the birds were fed cottonseed cake based diets from 4-8 weeks of age. Five dietary treatments were fed in both experiments formulated to be iso-caloric and iso-nitrogenous with Cottonseed Cake (CSC) replacing Soyabean Cake (SBC) at 0, 25, 50, 75 and 100% respectively. The live weight of broilers in the phases differed significantly (p<0.05) with broilers in phase 2 being better. The dressed weight was higher in phase 2 than phase 1. Broilers fed CSC based diets from 4 weeks had better feed conversion ratio than those fed from day old. Similar trend was observed in haematological and serum biochemistry parameters in the different treatments of the two phases. It can be concluded that feeding CSC protein as replacement for SBC protein was better from 4 weeks of age in respect of broiler performance though at a higher cost than the former.

两个实验用棉籽饼为主的饮食喂养鸟类表分别进行。在第一个实验（阶段1）肉鸡鸟从日龄〜8周龄喂，而在第二个实验（第2阶段），鸟类是从4-8周龄喂棉籽饼为主的膳食。五个日粮处理饲喂于配制成异热量和异氮与棉籽饼（CSC）代替大豆糕饼（SBC），分别在0，25，50，75和100％的两个实验。在阶段肉鸡的活重显著差异（P 0.05），肉鸡在第2阶段是更好的。在穿着重较高，第二阶段比第一阶段。肉鸡从4周馈送CSC为主的饮食具有比那些从日龄喂更好的饲料转化率。类似的趋势被观察到在两个阶段的不同的治疗血液学和血清生化参数。由此可以得出结论，在一个成本高于前者供给CSC蛋白作为替代SBC蛋白质是从4周龄更好就肉鸡性能虽然。
