                Abstract:The purpose of this study was to evaluate the different breeding program on the sows' reproductive
                performance. Eighty Landrace pregnant sows were randomly divided into two groups with forty sows in each
                group. Two kinds of diets were involved, and keep the same nutrient intake every day in each group. The re-
                sult showed as follows: There was no significant difference between the control group and the experimental
                group in the litter size. The number of diarrhea of treatment group was lower than the control. Compared
                with the control, the number of born alive, weaning and average weaning weight is significantly improved
                with 12.35%, 11.09% and 6.41% (P<0.05), respectively. In conclusion, the different breeding programs influ-
                enced the productive performance of sows, especially on the number of born alive and weaning weight.
