| 摘 要： | 目的]试验旨在探讨苦玄参提取物对仔猪生长性能的影响,为其在动物生产中更好地应用提供参考依据。方法]选取体重相近的28~35日龄杜×长×大三元杂交的健康断奶仔猪250头,随机分为5组(A、B、C、D、E组),每组设5个重复,每个重复10头。其中,A、B、C组依次为苦玄参提取物高、中、低3个剂量试验组,分别在基础日粮中添加3.500、1.750和0.875g/kg苦玄参提取物;D组在基础日粮中添加对照药物七补散4.0g/kg;E组为空白对照组,饲喂基础日粮,预饲期7d,正试期30d。于试验正式开始的第0天、第15天和第30天7:00分别对各组的每一头试验猪进行空腹称重,并每天记录每个组试验猪的采食量,计算平均日采食量(ADFI)、平均日增重(ADG)和料重比(F/G)。结果]添加苦玄参提取物后,A、B、C组仔猪的体重、ADG及ADFI,与E组相比显著或极显著(P<0.05或P<0.01)增加,而料重比降低;其中苦玄参提取物中剂量组仔猪的体重、平均日增重及平均日采食量提升最明显,料重比也极显著低于D组与E组(P<0.01)。结论]苦玄参提取物对仔猪生长具有一定的促进作用,以1.750g/kg的添加剂量添加在饲料中效果最佳。

| Abstract: | Objective]To assess the effect of Picria fel-tarrae Lour.extracts on the growth performance of piglets and to provide a reference for their better application in animal production.Method]A total of 250 healthy three-way crossbred pigs(Duroc×Landrace×Yorkshire)aged 28 to 35 days with similar weight were selected and randomly divided into 5 groups(A-E)with 5 replicates per treatment and 10 pigs per replicate.The groups of A,B and C were set as high-,middle-and low-dose Picria fel-tarrae Lour.extracts groups respectively,and fed diet with 3.500,1.750 and 0.875 g/kg Picria fel-tarrae Lour.extracts,respectively.The group D was a positive medicine control group fed a diet containing 4.0 g/kg Qibusan.The group E was set as a blank control group fed basal diet.The pre-feeding period was 7 days and the formal trial period lasted for 30 days.The experimental piglets in each group were weighed before feeding at 7:00 on the 0,15st and 17st day of the experiment,and the feed intake for each group were recorded.At the end of the experiment,the intergroup differences in average daily feed intake(ADFI),average daily gain(ADG)and feed to gain ratio(F/G)were statistically assessed.Result]The weight,ADG and ADFI of the groups of A,B and C were significantly or extremely significantly elevated compared to the group E(P<0.05 or P<0.01),while the F/G was reduced.The group B(middle-dose group)showed the best performance in increasing the weight,ADG and ADFI of piglets and had extremely significantly lower F/G compared to the groups of D and E(P<0.01).Conclusion]Picria fel-tarrae Lour.extracts have a certain growth promoting effect on piglets,and their optimal level of dietary supplementation was 1.750 g/kg. |
