How can first-litter sows produce more piglets
To improve the farrowing rate, attention should be paid to the following points:
1. Keep the sow in good body condition before mating, maintain the sow at 70-80% fatness, and do not let it become too fat. Short-term flushing 10-14 days before mating can increase the number of ovulations. The extent of the increase in feeding level is: feed 2-2.7kg more concentrate on top of the original daily ration, and reduce it immediately after mating is completed. For those in poor body condition, the feeding level should be raised even more to promote more ovulations.
2. Grasp the appropriate mating time: determine the first mating time according to the month age and body weight of the gilt; do not mate at the first estrus, but mate when estrus repeats after an interval of 21 days and the number of ovulations also increases. Mating age for various pig breeds: local breed sows should reach 60kg at 7-8 months of age, two-way crossbred sows should reach 75-80kg at 8-9 months, and introduced foreign breeds should reach 90-100kg at 9-10 months.
