【摘要】：为研究非淀粉多糖酶对玉米及其加工副产品非淀粉多糖(NSP)真代谢率的影响,试验选用56只平均体重为(2.5±0.2)kg的健康成年黄羽肉公鸡,采用完全随机试验设计,将其分为7组,每组8个重复,每个重复1只鸡,采用绝食强饲法进行5期代谢试验,以单一原料或添加复合非淀粉多糖酶为强饲饲料,测定玉米及其加工副产品中添加复合非淀粉多糖酶前后的非淀粉多糖真代谢率。结果表明:添加非淀粉多糖酶不同程度地提高了玉米及其加工副产品的不可溶性NSP(INSP)、可溶性NSP(SNSP)以及总NSP(TNSP)的真代谢率。加酶后,玉米、玉米胚芽粕、玉米纤维饲料、玉米蛋白饲料及DDGS(国产)中的INSP真代谢率较加酶前显著提高(P0.05),玉米、玉米纤维饲料、玉米蛋白粉(江苏徐州、吉林松原)、玉米蛋白饲料、DDGS(国产、进口)和玉米糖渣(山东沛县)的SNSP真代谢率显著提高(P0.05);就TNSP而言,加酶后,玉米、喷浆玉米皮(山东济宁)、玉米纤维饲料、玉米蛋白粉(吉林松原)、玉米蛋白饲料、DDGS(国产)和玉米糖渣(山东沛县、江苏徐州)的TNSP真代谢率较加酶前分别提高了25.94%(P0.001)、16.90%(P0.05)、15.24%(P0.05)、13.02%(P0.01)、27.05%(P0.05)、17.36%(P0.01)、12.70%(P0.01)以及13.87%(P0.05)。由此可知,添加复合非淀粉多糖酶能提高玉米及其加工副产品的非淀粉多糖真代谢率,改善玉米及其加工副产品的营养效价。
[Abstract]:In order to study the effect of non-starch polysaccharide enzyme on the true metabolic rate of corn and its processing by-product, 56 healthy adult yellow feather roosters with an average weight of 2.5 卤0.2)kg were selected and divided into 7 groups. Eight repeats in each group and one chicken in each repeats were used for 5-stage metabolic test with a hunger strike method, and a single raw material or a compound non-starch polysaccharide enzyme was used as the forage. The true metabolic rate of nonstarch polysaccharides in maize and its processing byproducts before and after the addition of compound nonstarch polysaccharide enzyme was determined. The results showed that the true metabolic rate of insoluble NSPN INSPN, soluble NSPN NSPN SPS and total NSPN N N SPP of maize and its processing byproducts were increased in different degree by adding NSP enzyme. The true metabolic rate of INSP in corn germ meal, corn fiber feed, corn protein feed and DDGS (made in China) was significantly higher than that before enzyme addition, corn fiber feed and corn protein meal (Xuzhou, Jiangsu Province). The true metabolism rate of SNSP in the corn protein feed DDGS (domestic, imported) and corn sugar residue (Pei County, Shandong Province) in Songyuan, Jilin Province, was significantly increased, while in the case of TNSP, after adding enzymes, corn husk was sprayed (Jining, Shandong, corn fiber feed). The true metabolism rate of TNSP in corn gluten powder (Jilin Songyuan, corn protein feed DDGS (domestic) and corn sugar residue (Pei County, Jiangsu Province, Xuzhou, Jiangsu) increased by 25.94% and 25.94%, respectively, as compared with that before enzyme addition. The true metabolic rate of corn protein powder (P 0.05) was increased by 25.94%, P 0.05 (P 0.05), P 0.02 (P 0.01 27.05) and 17.36T (P 0.070 P 0.01) and 13.87m P0.05 respectively. It can be concluded that the addition of compound non-starch polysaccharide enzyme can improve the true metabolism rate of corn and its processing byproducts, and improve the nutritional titer of maize and its processing byproducts.
