Savaging is most common in gilts with their first litters and is often associated with nervousness or apprehension in the gilt before farrowing. It may occur in some families or breeds and may be associated with fear of the new farrowing environment, especially when the animals have been loose housed prior to crating. nadis.org.ukИзображение:nadis.org.ukOnce the piglets are all born and the afterbirth is expelled, the sow will eat the dead/stillborn piglet. This is the first reason why a sow would eat a piglet. The second reason a sow would eat a piglet is that sometimes piglets are crushed by the sow. This is an accident, she was not behaving aggressively toward the piglet when it was killed. Sows do not get up to help the piglets from their membranes. The umbilical cord is normally torn when the piglet moves around to the udder.Sows are usually passive once farrowing starts, and carries out very few postural changes. Sows often stand, turn, and sniff the first piglets born ; but this behavior declines as more piglets are farrowed. Sows do not get up to help the piglets from their membranes.Light exposure has the potential to prevent or limit savaging in pigs as pigs exposed to light for 16–24 hours a day in farrowing room experienced a decrease in the prevalence of savaging. The industry has also attempted to avoid savaging behavior by limiting reproduction in gilts and sows that have previously savaged their offspring.

Why would a pig eat its babies?
Not all sows, but if a piglet dies for any reason, a sow with a good maternal instinct will eat it to prevent predators and scavengers from smelling the carcass and finding the rest of the litter, much like cows who eat their own placenta after a calf is born.
Why do sows crush their piglets?
The underlying reason for crushing and overlying is the disparity between the size of the piglet at birth (1.2 kg) and that of the sow (250 kg) and occurs particularly when the sow lies down to rest or to suckle the litter.
Why are pigs cannibals?
Field data collected in Europe suggested that pigs are more likely to become cannibalistic when housed on concrete slats. Other authors have suggested that feeding a grainbased, high energy diet in a mechanically-ventilated building would predispose pigs to cannibalism.
How do you stop a pig from being a cannibal?
Prevention1Assess the gilts when they come into farrow.2Try where ever possible to have a sow in a crate next to a gilt.3Constant supervision is required to identify animals at the onset of farrowing. … 4Give the gilt plenty of straw to eat pre-farrowing.Savaging of Piglets (Cannibalism) | The Pig Site
What happens if a sow eats a pig?
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. Fig 1: The newborn piglet is especially vulnerable to attack.
Do sows get up to help piglets?
Sows are usually passive once farrowing starts, and carries out very few postural changes. Sows often stand, turn, and sniff the first piglets born [2]; but this behavior declines as more piglets are farrowed. Sows do not get up to help the piglets from their membranes.
What behaviors do sows and piglets carry out in the wild?
There is a series of behaviors carried out, with sows and piglets undergoing various phases of isolation, community integration, and living.
How to prevent savaging of piglets during farrowing?
Fig 3: Boxing piglets away during farrowing may reduce the risk of savaging. Savaging of piglets most commonly occurs in gilt litters (but is not always restricted to them). This tends to mean that major problems are restricted to new herds where all farrowings are gilts.
