How many days does it take for a sow to wean five piglets?

The weaning time of piglets is related to the number of litters and live piglets per year. In general industrialized and intensive pig farms, piglets can be weaned in 4 to 5 weeks, and rural farmers can be weaned in about 7 weeks. Weaning methods of piglets include gradual weaning, batch weaning and one-time weaning.

-Step-by-step weaning method reduces the contact and lactation times between sows and piglets 3-4 days before weaning, reduces the daily feed intake of sows, and enables piglets to have an adaptive process from less breastfeeding to no breastfeeding, so as to reduce the influence of weaning stress on piglets. But this weaning method is more troublesome and laborious.

-Weaning a litter of piglets with large weight in batches, so that the weak piglets can continue breastfeeding for a period of time before weaning to improve their weaning weight. But this method will prolong the lactation period and affect the reproductive performance of sows.

-One-time weaning method reduces the daily feed intake of lactating sows three days before weaning, and separates piglets from sows when weaning. This weaning method comes suddenly, which will cause stress in piglets and irritability in sows, but it saves labor and time and is easy to operate.
