The prevention method of pig turning

The reason for the turning of pigs is a severe calcium deficiency in pigs. The weight of the pig is about 45 kg. It is a period when the pig's long skeleton is in its prime. If the calcium material can not meet the needs of the growth of the body, it will be restless and irritating. It will be dug around, often pushing down the wall and biting the shed. Earthworms, debris, etc.
Control methods: First increase the mixed feed, because it contains calcium substances. Second, increase the proportion of straw feed, rice stalks, weeds, sweet potato vines crushed to pigs. When pigs are "turned over", pigs can be fed eggshell powder, small snail meal, fresh poultry bone powder, and the like.
