【摘要】 试验采用鸡表观代谢能测定方法评定日粮表观代谢能价值(AME),试验动物选用成年的泰和乌骨鸡,日粮设计分两个营养水平组:低能量高蛋白水平日粮和高能量低蛋白水平日粮,日粮分别含有牛油、棕榈油和不同水平的鱼油。试验结果表明:1、低能量高蛋白日粮组的平均AME为12.18 MJ/kg,除牛油组AME低以外,其余各组的AME差异不显著(P>0.05);2、高能量低蛋白水平日粮的平均AME为12.68 MJ/kg,鱼油3组(添加4％鱼油)AME显著高于牛油组的AME(P<0.05),其余各组之间差异不显著(P>0.05)。本试验结果间接推导出,鱼油的AME价值高于牛油AME值,而与棕榈油AME值的接近。更多还原

【Abstract】 The experiment was conducted to evaluate the apparent metabolizable energy (AME) value of Taihe chick’s diet coutaining fish fat, beef tallow and palm oil. The diets were designed at two levels:Lower energy and higher protein (Group I ) and higher energy and lower protein (Group II) level. The results showed that:(1)The average AME value in Group 1 was 12. 18 MJ/kg and AME of diets containing beef tallow was significantly lower than those of other diets (P<0. 05). (2)The AME value of Group was 12. 68 MJ/kg. The AME value of diets containing 4% fish oil was remarkably higher than that in diets with 3% tallow (P<0. 05). The AME value of fish oil was higher than that of talliw, but similar to that of palm oil.更多还原
