How many days is it best to wean piglets?

Weaning is generally at the age of 2 1-25 days, which does not affect the next estrus of sows, and 28 days is a bit late.

Solve the following problems before weaning, and weaning at one time or in batches is handy:

1, the problem of digestive enzymes, the lactate enzyme value of piglets is the highest at birth and gradually decreases before weaning. Other digestive enzymes (including amylase, lipase, protease, maltase, etc. ) after leaving breast milk, it drops sharply, which makes it difficult for piglets to digest and utilize feed after weaning, so it is necessary to supplement enzyme precursors.

2. Intestine is the largest immune organ, and its environment is very important. When piglets are weaned, the intestinal PH changes greatly (for example, it rises from 3.8 on the day of weaning to about 6.4 on the third day), and it takes 10 ~ 15 days to gradually return to the normal level.

3. After weaning, the beneficial "biofilm" did not form in the intestine, and the intestinal villi and epithelial cells were very fragile.

4. The maternal antibody of piglets drops sharply before and after weaning, and it takes about 7 weeks to reach the barely protected level, so piglets have an "immune window period" from weaning to 7 weeks.

5. Before weaning, the intestinal non-breast milk nutrition stimulation training was not enough, and some feed raw materials were not palatable, which led to the decrease of piglet feed intake and the onset of diarrhea and emaciation.

The optimal formula of weaning developed by our company has been verified by 6000 pig farms, which has solved the above five weaning problems.
