Abstract: 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.
