A feeding experiment on 100 ternary hybrid pigs, Large Yorkshire×Landrace×Duroc, was carried out with the local energy feed (corn, rice bran) at Kaiyang. The experimental group was fed with concentrated feed which was produced by a company of Yunnan province with national green certificate, and that for control group was common concentrated feed without the certificate. The feeds were prepared with formula and to feed for 125 days. The results showed that the average daily gain of the experimental group increased by 5.23% comparing to the control group. It was significantly different (P＜0.05). The feed conversion ratio increased by 6.12% and the feeding cost had a slight reduce.
