复合酶对临武鸭几种饼粕饲料原料养分利用率和代谢能的影响
Effects of Compound Enzymes on Nutrient Utilization Rate and Metabolize Energy of Several Meal Type Feed Ingredients of Linwu Ducks
摘要
Abstract
The aim of this study was to determine the effects compound enzymes ( protease, cellulase and xyla-nase) on nutrient utilization rate and metabolize energy of several meal type feed ingredients ( soybean meal, soybean dregs, cottonseed meal, 2 kinds of rapeseed meal, peanut meal and 2 kinds of sesame meal) of Linwu ducks.Forty-eight healthy adult male Linwu ducks with body weight about 2.0 kg were randomly divided into 6 groups with 8 replicates in each group and 1 duck in each replicate.Three batch metabolic tests were carried out by hunger strike-gavage method.Two groups tests for each ingredient were divided into control group and sup-plemented with compound enzymes group ( added 250 mg/kg compound enzymes in test ingredient ) .Each duck was fed 60 g/d diet by gavage.Endogenous group was fed 60 g/d nitrogen-free diet by gavage.The ap-parent metabolic energy ( AME) , true apparent metabolic energy ( TME) and utilization rate and true utiliza-tion rate of dry matter ( DM) , crude protein ( CP) , ether extract ( EE) , crude fiber ( CF) of eight meal type feed ingredients supplemented with compound enzymes for Linwu ducks were determined.The results showed that the apparent utilization rates of DM, CP, EE and CF of eight meal ingredients were 38.85%to 62.86%, 50.73%to 65.39%, 50.16%to 74.50%and 32.32%to 46.46%, respectively.AME and TME were 6.82 to 12.72 MJ/kg and 8.79 to 14.69 MJ/kg, respectively.Adding compound enzymes, the effective nutrients im-provement values ( ENIV) of DM, CP, EE and CF were 6.25 to 21.70 g/kg, 2.60 to 16.73 g/kg, 0.13 to 8.66 g/kg and 0.66 to 2.74 g/kg, respectively, and the TME improved 0.19 to 1.15 MJ/kg.The results indi-cate that diet supplemented with compound enzymes can improve utilization rates of nutrient and metabolizable energy to a certain extent of Linwu ducks.关键词
