泰和丝毛乌骨鸡常用蛋白质饲料氨基酸的消化率

True Digestibilities of Amino Acids of Several Protein Sources in Silk Fowl

选用 9周龄和 12周龄泰和丝毛乌骨鸡各 12 0只 (雄、雌各 6 0只 ) ,采用代谢试验测定了不同性别泰和丝毛乌骨鸡对鱼粉、豆粕、菜籽粕和棉仁粕 4种常用蛋白质饲料的氨基酸真消化率。并分析了性别与周龄对泰和丝毛乌骨鸡氨基酸真消化率的影响。

Sixty male and 60 female Taihe silk fowls, 9 or 12 weeks old, were used to determine the true digestibilities of amino acids in fish meal, soybean meal, rapeseed meal and cotton seed meal. The effect of age and sex of the birds on the digestion of amino acids in the 4 feed ingredients were investigated as well.
