选取6头体重(35±1) kg、健康去势的鲁烟白猪,采用有重复的6×6拉丁方设计进行消化试验,试验饲粮为玉米和玉米-小麦饲粮,对照组不添加淀粉酶,试验组分别添加0.1%单酶C和0.1%复合酶,研究复合淀粉酶对鲁烟白猪不同淀粉来源饲粮养分消化率和氮平衡的影响. 结果表明,单酶C和复合淀粉酶都能提高鲁烟白猪饲粮养分消化率和对氮的利用率,但复合酶的效果好于单酶. 在玉米、玉米-小麦饲粮中添加复合淀粉酶对鲁烟白猪干物质、粗蛋白质和有机物消化率分别比对照组提高3.82个百分点、0.41个百分点、3.36个百分点和4.79个百分点、1.16个百分点、4.05个百分点(P<0.01);氮表观消化率、氮生物学价值和蛋白质净利用率分别提高2.86个百分点、1.60个百分点、2.47个百分点,3.08个百分点、2.33个百分点、2.70个百分点(P<0.05);与添加单酶C相比,在两种饲粮中添加复合淀粉酶时,鲁烟白猪干物质、粗蛋白质和有机物消化率分别提高1.39个百分点、0.14个百分点、0.65个百分点,1.61个百分点、0.49个百分点、2.63个百分点(P>0.05); 氮表观消化率、 氮生物学价值和蛋白质净利用率分别提高1.14个百分点、0.55个百分点、0.92个百分点,1.45个百分点、0.72个百分点、0.71个百分点(P>0.05);并且玉米-小麦型饲粮中加入复合淀粉酶对饲粮养分消化率的改善效果优于玉米型饲粮.
選取6頭體重(35±1) kg、健康去勢的魯煙白豬,採用有重複的6×6拉丁方設計進行消化試驗,試驗飼糧為玉米和玉米-小麥飼糧,對照組不添加澱粉酶,試驗組分彆添加0.1%單酶C和0.1%複閤酶,研究複閤澱粉酶對魯煙白豬不同澱粉來源飼糧養分消化率和氮平衡的影響. 結果錶明,單酶C和複閤澱粉酶都能提高魯煙白豬飼糧養分消化率和對氮的利用率,但複閤酶的效果好于單酶. 在玉米、玉米-小麥飼糧中添加複閤澱粉酶對魯煙白豬榦物質、粗蛋白質和有機物消化率分彆比對照組提高3.82箇百分點、0.41箇百分點、3.36箇百分點和4.79箇百分點、1.16箇百分點、4.05箇百分點(P<0.01);氮錶觀消化率、氮生物學價值和蛋白質淨利用率分彆提高2.86箇百分點、1.60箇百分點、2.47箇百分點,3.08箇百分點、2.33箇百分點、2.70箇百分點(P<0.05);與添加單酶C相比,在兩種飼糧中添加複閤澱粉酶時,魯煙白豬榦物質、粗蛋白質和有機物消化率分彆提高1.39箇百分點、0.14箇百分點、0.65箇百分點,1.61箇百分點、0.49箇百分點、2.63箇百分點(P>0.05); 氮錶觀消化率、 氮生物學價值和蛋白質淨利用率分彆提高1.14箇百分點、0.55箇百分點、0.92箇百分點,1.45箇百分點、0.72箇百分點、0.71箇百分點(P>0.05);併且玉米-小麥型飼糧中加入複閤澱粉酶對飼糧養分消化率的改善效果優于玉米型飼糧.

Six similar weight (35±1) kg,healthy and casteated growing pigs of Lu-Yan White pigs was selected. Then these pigs were divided into two groups,their diets have different starch source,corn and corn-wheat.The diets of which group were managed 3 situation,no amylase,single amylase,complex amylase.This experiment was completed through the way of 6 ×6 latin square design. The results show that,the nutrient digestibility and nitrogen utilization of Lu-Yan white pigs increased,when adding the composite amylase to the diet that has different sources of starch,and it's better to add single amylase.Compared with the blank group,the dry matter digestibility,crude protein digestibility and organic matter digestibility of experimental group adding the composite amylase in the diet of corn and corn-wheat increased by 3.82,0.41,3.36,4.79,1.16,4.05 percent(P<0.01);nitrogen apparent digestibility,nitrogen biological value and protein utilization increased by 2.86, 1.60, 2.47, 3.08, 2.33, 2.70 percent (P<0.05);compared with the single amylase group,the project of nutrient digestibility and nitrogen balance increased by 1.39, 0.14, 0.65, 1.61, 0.49, 2.63 percent (P>0.05);1.14, 0.55, 0.92, 1.45, 0.72, 0.71 percent (P>0.05);and the effect of adding amylase in the diet of corn-wheat was better than adding amylase in the diet of core.
