摘　　要：在营养水平一致的条件下,小麦取代生长猪日粮中全部玉米并添加有针对性的复合酶制剂,在40 d的生长期内,表现较佳的试验Ⅱ组的日增重提高9.79%(P<0.05);比不添加酶制剂的全小麦日粮日增重提高18.78%左右(P<0.05),饲料效率提高18%以上(P<0.05);同时试验表明,酶制剂的添加剂量对生长猪生产性能的影响很大。在玉米和小麦价格相当的条件下,使用营养水平一致的全小麦日粮可使生长猪只在40 d的试验期经济效益能提高70元/头以上,增幅达17.3%。At the same nutrient level, the average daily gain was increased by 9.79% （P〈0.05） that the diet of growing swine with all corn replaced by wheat with the special compound enzyme preparation compared with the diet of corn type during the growth period of 40 days, and the average daily gain was improved by about 18.78% （P〈0.05） compared with the diet of wheat type without enzymes prepa- ration. Feed efficiency was improved by more than 18% （P〈0.05）. in addition, it also showed that the dose of enzyme preparation played a key role in production performance of growing pig. If the pric- es of corn and wheat were same with the same nutrient level, the whole wheat type diet could in- crease the economic benefit by over 70 yuan per pig, up 17.3% compared with the diet of corn type in the test period of 40 days.
