应用优质饲用玉米饲喂生长育肥猪的试验研究

本研究旨在探讨饲用玉米对生长育肥猪生产性能的影响。选取体重(40±1) kg相近的大白×长白×杜洛克商品猪21头，随机分为3组，每组7头，分别饲喂以普通玉米（N组）和饲用玉米吉单198（T1组）、吉单327（T2组）为饲料原料的日粮，进行了78 d的饲养试验。结果表明，T1组、T2组育肥猪的日增重分别较N组提高了10.37%、2.22%，各组试验猪的饲料转化效率基本一致。平均每头猪的纯收入：T1组和T2组分别比对照组每头多85.1和36.1元。因此，本试验结果表明，饲用玉米能够提高生长育肥猪的生产性能，从而增加养殖效益。

Study on Feeding Trial of Fodder Maize in Growing-Finishing Pig

The aim was to check out influence of fodder maize on the performance of growing-finishing pig. Twenty-one crossbred (Duroc×Landrace×Yorkshire), (40±1) kg growing-finishing pigs were randomly and equally separated into three treatments based on their weight. Pigs in each treatment were respectively fed diets supplemented with general maize (N group), Jildan 198 (T1 group), Jidn327 (T2 group) for 78 days. The daily gain of T1 group and T2 group increased 10.37%, 2.22% compared with control group respectively, the feed conversion rate of three groups are basically similar. The net profit of every pig in T1 group and T2 group increase 85.1 yuan and 36.1 yuan compared with control group respectively. The results indicate that fodder maize could enhance performance of growing-finishing pig and return revenue.
