The invention discloses a three-stage complete feed for improving the breeding rate of replacement gilts, a feeding method and a preparation method. The three-stage complete feed is divided into a growth material, a fattening material and an aphrodisiac material, and the three-stage complete feed is fed to the replacement gilts according to the table 1. According to the invention, after the replacement gilts are about 50kg in weight, the replacement gilts are bred by using the three-stage complete feed and the feeding mode, and compared with the mode of using the same-stage feed in the whole process, the nutritional requirements are better met, and the body conditions of the replacement gilts are more effectively adjusted. The three stages also avoid the phenomenon of nutrient waste caused by relatively high nutrient level of daily ration in the same stage. Meanwhile, by using compound fermented fibres, the intestinal health of the replacement gilts is facilitated, the immunity is improved, and the elimination rate is also reduced. In the third stage, the aphrodisiac material has a special aphrodisiac formula, and mainly comprises starch daily ration, the ovulation number of the replacement gilts can be increased, and the live litter size of the first birth is correspondingly increased.
