What happens if you mix weaning pigs with other pigs?

Grouping piglets according to litter origin has been shown to be related to the degree of aggression (Colson et al., 2006). Moreover, weanling exposure to foreign piglets at early stages of life can be stressful and can affect growth rate, lead to aggression, and cause injury (D’Eath, 2005). Weaning causes morphological and functional changes of the small intestine of pigs, where most of the nutrients are being digested and absorbed. While various stressors induce post-weaning growth depression, the abrupt change from milk to solid feed is one of the most apparent challenges to pigs.



Will other pigs eat baby pigs?

Occasionally sows will attack their own piglets – usually soon after birth – causing injury or death. In extreme cases, where feasible, outright cannibalism will occur and the sow will eat the piglets. The development of this behaviour is often complex and difficult to stop and can cause significant losses.

Do baby pigs fight?

This can take 3 days or it could be 3 weeks. They will likely fight. They’re herd animals, they have a herd mentality and have to battle it out to see who will get the top hog position. It’s a way of life for them.

What will you do to avoid fighting among piglets?

Strategies to prevent pig aggression

In piglets, aggression can be prevented at weaning by socialising them during lactation. Early socialisation during the first two weeks after birth improve the social abilities of piglets and reduces the aggressive encounters in future events of mixing.

Does weaning affect the health of Pigs?

Just after weaning, there are some facts that most producers believe in like the growth performance of pigs is normally decreased, health also is adversely affected by weaning and mortality is a common incidence during that time.

What is split weaning in pigs?

The process involves weaning the heavier piglets in a litter a few days before weaning the smaller ones. This allows smaller piglets access to a larger milk supply with less competition. To ensure that smaller piglets in the litter will benefit from split weaning, wean the heaviest piglets three to five days early.

How old do pigs have to be to wean?

The Weaning in Pigs Process – removal of milk access Old system: at 8 weeks. By this time the sow’s milk production is declining substantially, and solid feed consumption by piglets is sufficient to account for 70-80% of nutritional requirements. Weaning at this age is a natural process.

What happens when you mix up piglets?

This is a recipe for fighting as each pig must try to establish its place in the new hierarchy. Not only does this lead to injuries from bites and higher stress levels amongst those piglets, but, also a reduction in growth when compared to unmixed groups.
