摘要: 试验旨在研究日粮中添加中药复方发酵粉对断奶仔猪生长性能、养分表观消化率和消化酶活性的影响。选择32头体重为(14.96±0.96)kg的健康42日龄"杜×长×大"三元断奶仔猪,随机分成4个处理,每个处理8个重复,每个重复1头猪。对照组饲喂基础日粮,其余3组分别在基础日粮的基础上添加金霉素75 mg/kg、中药复方发酵粉600 mg/kg及金霉素75 mg/kg+中药复方发酵粉600 mg/kg。试验期为42 d。结果表明,日粮中添加中药复方发酵粉显著提高了仔猪的干物质、有机物和碳水化合物的表观消化率及表观消化能(P<0.05),提高了必需氨基酸和非必需氨基酸(甘氨酸、天冬氨酸、丙氨酸、胱氨酸、酪氨酸)的表观消化率及脂肪酶活性(十二指肠、空肠、回肠)和淀粉酶活性(回肠)(P<0.05)。金霉素和中药复方发酵粉对仔猪日增重、粗脂肪和粗蛋白质的表观消化率及表观消化能和亮氨酸、苯丙氨酸、丝氨酸的表观消化率有显著的交互效应(P<0.05);与对照组相比,金霉素组和中药复方发酵粉组显著提高了日增重、粗脂肪和粗蛋白质的表观消化率及苯丙氨酸和丝氨酸的表观消化率(P<0.05),但两组间差异不显著(P>0.05)。由此可见,日粮中添加600 mg/kg中药复方发酵粉能提高断奶仔猪养分表观消化率、氨基酸表观消化率和肠道消化酶活性。

Abstract: This study was conducted to investigate the effects of Chinese herbal compound fermentation powder (CHCF) on growth performance,nutrient apparent digestibility and digestive enzyme activities of weaned piglets.A total of 32 healthy 42-day-old weaned piglets (Duroc×Landrace×Large White) with an average body weight of (14.96±0.96) kg were randomly divided into 4 treatments,8 replicates per treatment,and 1 pig per replicate.The control group was fed the basal diet,and the other three groups were supplemented with chlortetracycline (CC) 75 mg/kg,CHCF 600 mg/kg,CC 75 mg/kg+CHCF 600 mg/kg.The experiment lasted for 42 days.The results showed as follow:Supplementation of CHCF had significantly increased the apparent digestibility of dry matter,organic matter and carbohydrates and the apparent digestible energy (ADE) (P<0.05),increased the apparent digestibility of essential amino acid and non-essential amino acid (Gly,Asp,Ala,Cys and Tyr),activities of lipase (duodenum,jejunum and ileum) and amylase (ileum) (P<0.05).CHCF and CC had a significant interaction on average daily gain (ADG) and ADE,the apparent digestibility of crude protein (CP) and ether extract (EE),and the apparent digestibility of Leu,Phe and Ser (P<0.05).Compared with control group,CHCF and CC group had significantly increased ADG and the apparent digestibility of CP and EE,the apparent digestibility of Phe and Ser (P<0.05),but there were no significant difference between two groups (P>0.05).In conclusion,the addition of 600 mg/kg CHCF in diets could improve the nutrient apparent digestibility,apparent digestibility of amino acid and intestinal digestive enzyme activities of weaned piglets.
