| 摘 要： | 本试验旨在比较鹅和鸡常用饲料原料的代谢能差异.选用体重为(3.76±0.23)kg的成年扬州鹅(公)和体重为(2.57±0.17)kg的成年新扬州鸡(公)各10只,采用Sibbald真代谢能法测定玉米、豆粕、稻谷、麦麸4种常用饲料原料的代谢能值,内源能测定采用饥饿法.结果表明:玉米、豆粕的表观代谢能(AME)鹅与鸡差异不显著(P＞0.05),真代谢能(TME)鹅显著低于鸡(P＜0.05)；而稻谷、麦麸的AME鹅显著高于鸡(P＜0.05),TME鹅与鸡差异不显著(P＞0.05).每小时内源能排出量,除强饲豆粕条件下鹅略高于鸡但差异不显著外(P＞0.05),强饲其他3种饲料条件下,鹅均显著高于鸡(P＜0.05).由此表明,鹅的饲料代谢能与鸡的并不完全相同,部分饲料的代谢能鹅和鸡之间存在显著差异,并且鹅的内源能排出量高于鸡.

| Abstract: | This experiment was conducted to compare metabolizable energy values of some common feedstuffs for gander and cockerel.In the experiment,ten adult Yangzhou ganders with weight of(3.76±0.23) kg and ten adult New Yangzhou cockerels with weight of(2.57±0.17) kg were employed to measure metabolizable energy values of 4 common feedstuffs(corn,soybean meal,paddy and wheat bran) using Sibbald method.Endogenous energy loss(EEL) was measured with starved birds.The results showed that apparent metabolizable energy(AME) of corn and soybean meal for gander was similar to that for cockerel(P>0.05),whereas true metabolizable energy(TME) of corn and soybean meal for gander was significantly lower than that for cockerel(P<0.05).The AME of paddy and wheat bran for gander was significantly higher than that for cockerel(P<0.05).There were no significant differences between gander and cockerel in TME of paddy and wheat bran(P>0.05).The EEL of gander was slightly higher than that of cockerel when the birds were fed soybean meal.However,the EEL of gander was significantly higher than that of cockerel when the birds were fed feedstuffs except soybean meal(P<0.05).It is concluded that metabolizable energy values of some feedstuffs for gander are not consistent with those for cockerel.The metabolizable energy values of some feedstuffs are similar between gander and cockerel,however,the others are different.The EEL of gander is higher than that of cockerel. |
