4种配合饲料对育肥猪生长性能及经济效益的影响

试验旨在研究猪场自配小麦型饲料、自配玉米型饲料和商品配合颗粒饲料对肉猪生长性能的影响。采用对比试验设计，选用108头育肥猪随机分为4组，每组3个重复，每个重复9头猪。A组饲喂玉米型基础料+A型预混料，B组饲喂小麦型基础料+B型小麦专用预混料，C组饲喂玉米型基础料+C型预混料，D组饲喂D型生长育肥猪配合饲料，试验期31 d。结果显示，各组间平均日采食量、日增重和料重比差异均不显著（P>0.05）；A组增重饲料成本与其他3组之间差异均不显著（P>0.05），B组与C、D组之间均差异显著（P<0.05），C、D组之间差异不显著（P>0.05）。综合分析得出，B组获得的经济效益最高，每头平均利润达473.07元。

Effects of Four Kinds of Compound Feeds on Growth Performance and Economic Benefits in Fattening Pigs

This experiment was conducted to study the effects of different feed types including self-made wheat type feed, corn type feed, commercial formula feed on the growth performance of fattening pigs. A contrast experiment design was adopted, and a total of 108 fatting pigs were randomly assigned into four treatments with three replicates and nine pigs per replicate. A group was fed corn-based and A premix feed, B group was fed wheat-based and wheat-specific B premix feed, C group was provided corn-based and C premix feed, D group was fed compound feed of D. The experiment lasted for 31 days.The results showed that there were no significant differences in the average daily feed intake, daily gain and feed to gain ratio among these groups (P>0.05). A group showed no significant difference (P>0.05) compared with groups B, C, D on feed costs, respectively. At the same time, B group showed significant influence compared with groups C and D (P<0.05). And there was no significant influence between groups C and D (P>0.05). In conclusion, group B had the lowest feed cost to weight gain and it got 473.07 yuan per pig.
