| 摘 要： | 采用单因子试验设计,研究了液态蛋氨酸羟基类似物(HMB)作为酸化剂对饲料品质和仔猪生产性能的影响。选用96头(28±3)日龄断奶的杜×长×约(DLY)仔猪,随机分为5个处理组:3个HMB组(每吨饲料中添加HMB为1.14、2.28、3.42kg)、对照组(基础日粮组)、复合酸化剂组(每吨饲料中添加3.0kg复合酸化剂)。结果表明,①HMB降低了饲料系酸力。②试验1～6周,添加HMB1.14kg/t组和2.28kg/t组均显著提高了采食量、日增重和饲料利用效率(P<0.05);添加HMB2.28kg/t组提高仔猪生产性能的效果优于复合酸化剂组(P>0.05)。③添加HMB显著降低了仔猪腹泻率(P<0.05)。HMB在断奶仔猪饲料中具有酸化剂作用。

| Abstract: | One factor design was conducted to investigate the efficacy of supplementation of methionine hydroxy analogue 2-Hydroxy-4-(methylthio) butanoic acid, HMB) on acidifier in the diet of piglets. A total of 96 weanling crossbred piglets (Duroc × Landrace ×Yorkshire) were randomly allocated into 5 treatments: Control, HMB 1.14, 2.28 and 3.42kg/t, acidifier 3.0kg/t. The results showed that: ①HMB decreased the dietary buffer capacity. ②HMB 1.14 and 2.28kg/t significantly improved ADG,ADFI and feed conversion rate (P<0.05), especially in 1～6 weeks post-weaning. The response of HMB 2.28kg/t was better than acidifier group(P>0.05). ③HMB significantly reduced the diarrhea rate of piglets (P<0.05). HMB can be used as acidifier to improve performance of the weaned piglets . |
