摘要

本试验旨在评价白酒糟和发酵白酒糟的营养成分含量及鸡、鸭、鹅对其的仿生消化总能(SDGE)和代谢能(ME),分别利用仿生消化法和生物学法(排空强饲法)测定。结果表明:1)白酒糟中干物质、粗蛋白质、粗灰分和总磷含量分别为85.63%、18.43%、1.49%和0.21%,均显著低于发酵白酒糟中的89.15%、24.75%、2.37%和0.38%(P<0.05);白酒糟中粗脂肪和粗纤维含量分别为4.64%和24.15%,均显著高于发酵白酒糟中的3.61%和15.50%(P<0.05)。2)鸡、鸭、鹅对白酒糟的SDGE分别为11.15、11.54和10.02 MJ/kg,均显著低于发酵白酒糟的11.86、12.23和10.78 MJ/kg(P<0.05)。3)樱桃谷肉鸭对白酒糟的表观代谢能(AME)为10.42 MJ/kg,真代谢能(TME)为11.29 MJ/kg,能量表观利用率为55.01%,均显著高于杏花公鸡(AME为8.13 MJ/kg,TME为9.39 MJ/kg,能量表观利用率为44.79%)和四川白鹅(AME为8.20 MJ/kg,TME为9.16 MJ/kg,能量表观利用率为43.91%)(P<0.05);而杏花公鸡、樱桃谷肉鸭、四川白鹅对发酵白酒糟的AME、TME、能量表观利用率和能量真利用率则无显著差异(P>0.05)。由此可见,发酵白酒糟中的粗蛋白质、总磷含量高于白酒糟,粗纤维含量低于白酒糟;鸡、鸭、鹅对发酵白酒糟的SDGE均高于白酒糟;樱桃谷肉鸭对白酒糟的ME高于杏花公鸡、四川白鹅;而杏花公鸡、樱桃谷肉鸭、四川白鹅对发酵白酒糟的ME则无显著差异。

Abstract

This experiment was conducted to study the nutrient contents in distiller's grains and fermented distiller's grains, and to determine the simulative digestion of gross energy (SDGE) and metabolizable energy (ME) of distiller's grains and fermented distiller's grains of cocks, ducks and geese used simulated digestion method and biological method (emptying and gavage). The results showed as follows: 1) the contents of dry matter (85.63%), crude protein (18.43%), ash (1.49%)and total phosphorus(1.49%)in distiller's grains were significantly lower than the contents of dry matter (89.15%), crude protein (24.75%), ash (2.37%)and total phosphorus (0.38%)in fermented distiller's grains (P<0.05). The contents of crude fat and crude fiber in distiller's grains were 4.64% and 24.15%, respectively, which were significantly higher than the contents of crude fat (3.61%) and crude fiber (15.50%) in fermented distiller's grains (P<0.05). 2) The SDGE of distiller's grains in cocks, ducks and geese were 11.15, 11.54 and 10.02 MJ/kg, respectively, which were significantly lower than the SDGE of fermented distiller's grains in cocks (11.86 MJ/kg), ducks (12.23 MJ/kg) and geese (10.78 MJ/kg) (P<0.05). 3) The apparent metabolizable energy (AME) was 10.42 MJ/kg, the true metabolizable energy (TME) was 11.29 MJ/kg, the energy apparent availability was 55.01% of distiller's grains in Cherry Valley ducks, which were significantly higher than the AME (8.13 MJ/kg), TME (9.39 MJ/kg), energy apparent availability (43.91%) of distiller's grains in Xinghua cocks and the AME (8.20 MJ/kg), TME (9.16 MJ/kg), energy apparent availability (44.79%) of distiller's grains in Sichuan white geese(P<0.05). The AME, TME, energy apparent availability and energy true available of fermented distiller's grains in Cherry Valley ducks, Xinghua cocks and Sichuan white geese were no significant differences (P>0.05). In conclusion, the contents of crude protein and total phosphorus in fermented distiller's grains are higher than those in distiller's grains, and the crude fiber content is lower than that in distiller's grains. The SDGE of fermented distiller's grains in cocks, ducks and geese is higher than that of distiller's grains. The ME of distiller's grains in Cherry Valley ducks is higher than that of distiller's grains in Xinghua cocks and Sichuan white geese. The ME of fermented distiller's grains has no effect in Cherry Valley ducks, Xinghua cocks and Sichuan white geese.
