【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%(P0.05);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%(P0.05)。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(P0.05)。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%)(P0.05);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(P0.05)。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]:The aim of this study was to evaluate the nutritional composition of white lees and fermented white lees, as well as the contents of chickens and ducks. The biomimetic digestibility total energy (SDGE) and metabolic energy (MEP) of geese were determined by bionic digestion method and biological method respectively. The results showed that the dry matter and crude protein in white lees were determined by the method of dry matter and crude protein. The contents of crude ash and total phosphorus were 1.49% and 0.21%, respectively, which were significantly lower than those in fermented white lees (89.15%) and 24.75% (2.37%) and 0.38% (P 0.05), respectively. The contents of crude fat and crude fiber in white lees were 4.64% and 24.15%, respectively, which were significantly higher than those in fermented white lees (3.61% and 15.50%, P 0.05 路2), ducks, ducks, and ducks, respectively. The SDGE of goose for white distiller's lees were 11.15 MJ / kg and 10.02 MJ / kg, respectively, which were significantly lower than those of fermented white distiller's lees (11.86N 12.23 and 10.78 MJ / kg P0.05N 路3). The apparent metabolizable energy of Cherry Valley ducklings for white lees was 10.42 MJ / kg, true ME = 11.29 MJ / kg, and apparent energy utilization ratio was 55.01, which was significantly higher than that of Cherry Valley ducks. AME was 8.13 MJ / kg, TME was 9.39 MJ / kg, apparent energy utilization ratio was 44.79%, AME was 8.20 MJ / kg TME was 9.16 MJ / kg, energy apparent utilization ratio was 43.91g / kg, and AME was 9.16 MJ / kg, while AME was 43.91mg / kg. There was no significant difference in apparent energy utilization ratio and true energy utilization ratio between cherry valley meat duck and Sichuan white goose on AME-TME-fermenting white distiller's grains. It can be seen that the crude protein, total phosphorus content and crude fiber content in fermented white lees were higher than those in white lees, and the crude fiber content was lower than that in white distiller's grains. The SDGE of fermented white lees of chicken, duck and goose was higher than that of white wine lees; the ME of Cherry Valley Meat Duck was higher than that of Apricot Flower Rooster and Sichuan White Goose, while the ME of Apricot Rooster, Cherry Valley Meat Duck and Sichuan White Goose had no significant difference.
