摘　　要：试验选用三黄鸡、海南阉鸡、北京白鸭和海南鸭各4只,分别采用4×4拉丁方设计,测定家禽对玉米、小麦、糙米、木薯4种饲料营养物质的代谢,以评定这4种饲料的营养价值,并分析比较鸡鸭对营养物质利用的异同。结果表明,4种饲料在鸡鸭中的表观代谢能(AME)玉米最高,木薯最低,玉米、糙米、小麦三者差异不显著(P>0.05);海南阉鸡和海南鸭对玉米的AME与木薯比较差异显著(P≤0.05);三黄鸡和北京鸭对玉米的AME与木薯比较差异极显著(P≤0.01)。鸡鸭对4种饲料粗脂肪、表观氮和真氮的消化率,玉米最高,糙米与玉米之间差异不显著(P>0.05);木薯较低,与玉米比较差异显著(P≤0.05)。对4种饲料中粗纤维的消化率,海南阉鸡、北京鸭、海南鸭对糙米中粗纤维的消化率最高,与玉米差异显著(P≤0.05),玉米与木薯之间差异不显著(P>0.05)。对4种饲料的AME及主要营养物质的消化率,鸡、鸭之间无显著差异(P>0.05)。The objective of the experiment was to determine nutrient value of corn, wheat, brown rice and cassava, and compare the ability of chickens and ducks to nutrition of the feedstuffs. According to 4×4 Latin square design, four Sanhuang Chicken, Hainan Chicken, Beijing Duck and Hainan Duck were used respectively. The results showed： The apparent metabolizable energy （AME） of corn in birds was highest,the AME of cassava in birds was lowest. The difference of AME in corn,brown rice and wheat were not significant （p〉0.05）. The difference of AME in Hainan Chicken and Hainan Duck between corn and cassava were significant （p ≤0.05）. The difference of AME in Sanhuang Chicken and Beijing Duck between corn and cassava were very significant （P≤0.01）. The birds＇ digestibility of crude fat and protein in corn was highest, there were no significant between corn and brown rice （p〉0.05）, and the difference was sig- nificant between corn and cassava （p ≤0.05）. The digestibility of crude fibre in brown riee in Hainan Chicken,Beijing Duck and Hainan Duck were highest, the difference between corn was significant （p ≤0.05）. But the difference between corn and cassava was not significant （P〉0.05）. There were no significant difference between chickens and ducks in AME and digestibility of four determined feedstuffs （P〉0.05）.
