In pig raising production, delay or no oestrus of sows after weaning is a problem which generally exists in recent years and always affects the pig raising industry. For a large-scale pig farm, the postweaning estrus rate of sows directly influences the production cost and the production score of the whole pig farm, the delayed weaning sow estrus causes that the sows cannot be bred on time, the breeding rate is reduced, and the number of delivered pigs and the number of born pigs in the pig farm are influenced. About 20% of the sows which are eliminated from some pig farms in a year are eliminated due to the reason, and great economic loss is caused to the production of the pigs. Shortening the interval from the weaning to the re-oestrus of the sows is the most concerned and most urgent technical problem to be solved in pig farms.
In the stage from weaning to oestrus, the weaned sows need to undergo weaning, physical function recovery, in-vivo hormone change caused by oestrus and the like, and the nutrition needs to be greatly different in different growth stages, so that the use of the adaptive feed and feeding mode in different stages is very important for the healthy breeding of the weaned sows. The reasonable breeding method can achieve the effect of twice with half the effort in breeding the sows, is beneficial to the component utilization of the feed, reduces the waste of the feed, reduces the breeding cost, is also beneficial to the health of the sows, achieves a good health-care effect on the sows, enhances the immunity of the sows, shortens the oestrus time of the weaned sows, and is beneficial to the quick body recovery and the recuperation of the weaned sows.
