| 摘 要： | 选用26周龄尼克粉公母鸡,结合套算法分别测定甘薯干、米糠、粟、糙米、葵花饼、啤酒糟、玉米蛋白粉和DDGS(玉米干酒糟)8种饲料原料的表观代谢能和蛋白代谢率。结果表明,用尼克粉鸡测得能量原料米糠、糙米表观代谢能公母间差异显著(P<0.05),母鸡测得的平均结果比公鸡分别高出0.61、1.03 MJ/kg,能量原料甘薯干、粟和葵花饼、酒糟、玉米蛋白粉、DDGS 4种蛋白原料的表观代谢能公母间差异不显著(P>0.05);米糠和葵花饼、酒糟、DDGS的粗蛋白代谢率公母间差异显著(P<0.05);玉米蛋白粉和甘薯干、粟、糙米的粗蛋白代谢率差异不显著(P>0.05),母鸡测得的平均结果均高于公鸡。说明性别对蛋鸡饲料蛋白和能量代谢有影响。

| Abstract: | Experiments were conducted to investigate the effect of gender of 26-wk-old Nick Pink on apparent metabolizable energy(AME) and protein metabolic rate of eight feedstuffs.Protein and energy of basal diet were substituted separately by dried sweet potatoes,rice bran,pearl millet and brown rice as energy supplements while sunflowers meal,sorghum-distiller's grains,corn gluten meal and distillers dried grains with solubles(DDGS) as protein supplements.The results showed that the difference of AME between roost... |
