Comparison on Energy Availability in Distiller's Grains and Fermented Distiller's Grains of Cocks, Ducks and Geese
摘要
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.关键词
