Abstract: Eighteen growing-finishing pigs on the average weight of (35±2.1) kilos were selected in this experiment and were divided into 3 groups. We fed the control group on basal date grain and added respectively 15% and 25% of fermentation rabbit excrement to the date grain to raise the treatment groupⅠ and the treatment group Ⅱin the 81 days of contrast experiment. The experiment result indicated that the intake of the treatment groups was more than the control group and the daily gain of the treatment groupⅠ and the treatment groupⅡ were respectively slower in the ratio of 1.84% and 8.3% than the control group. According to the economic profit analysis, the ration cost of the treatment groupⅠand the treatment group Ⅱ reduced respectively 0.19￥and 0.25￥when the weight of the growing-finishing pigs increased one kilo.
