The suckling period of piglets is generally 28 days to 60 days in our country. Large-scale farms generally take 35 days of weaning. Some were weaned at 28 days, 42 days, or 60 days of age. The best feeding conditions are 40-day-50-day-old weaning.

Suitable weaning methods:

There are three types of weaning methods, namely one-time weaning method, batch weaning method and gradual weaning method. The most commonly used method in production is the removal of the weaned weaning method.

1, move the mother does not change the weaning method

That is, at the time of weaning, the sow is removed, the piglet is kept in the original circle, and the mother is separated at one time. This method is simple, so that the occurrence of environmental stress in piglets can be avoided and the sow can be quickly estrus after weaning. The disadvantage is that sows are prone to mastitis due to the sudden weaning of piglets; piglets are susceptible to falling out due to sudden weaning. In order to prevent mastitis, the sows should be reduced or stopped eating before or 3 days before weaning.

2, batch weaning method

The short-sighted, well-developed piglets will be weaned first, allowing the young piglets to continue feeding and then weaning at a certain time. This method is conducive to the survival and growth of the weak piglets; the disadvantage is that the weaning period is long and the piglets weaned are left empty. Nipples are susceptible to mastitis.

3, gradually weaning method

During the 4 to 6 days before weaning, the number of piglet feedings was gradually reduced every day until complete weaning. This method is beneficial to mothers, but it is more troublesome.
