Postpartum should pay attention to sow bite
In swine production, the phenomenon of sows killing or eating their own piglets occurs from time to time. To analyze the reasons, there are mainly the following points:
First, sows are hungry or malnourished.
Long-term feed alone, lack of feeding, lack of protein, minerals, vitamins and other nutrients, coupled with hunger, resulting in sow feeding behavior. This situation is more common in thin old sows or primiparous sows.
Second, sows motherhood is too strong.
Sows who have ever eaten a litter of piglets or smelly piglets, or have swallowed a child's birth clothing, miscarried a fetus, and developed a diet.
Third, can not drink water in time.
During sow farrowing, high tension, shortness of breath, and loss of fetal water lead to thirsty sows. If water is not added in time, causing the sow to become impatient, biting piglets will occur.
Fourth, pain and fear.
Some of the first-born sows had not seen piglets and thought that the piglets would hurt themselves and have fear. When the sow sees the piglet, she often has large eyes and is ready to attack. Once the piglets are close, they are either killed or bitten. In some cases, the sows are difficult to produce and suffer from pain. Often the pain is vented to the piglets, killing the piglets.
Preventive measures:
(1) To strengthen the feeding of pregnant sows, diet composition should be diversified to meet the needs of sows for protein, minerals, and vitamins.
(2) Do a good job of consignment work so that the sow can leave after the baby is finished and remove the stillbirth and the placenta in time so that the sow will not be swallowed. If some sows need to use the tire clothing to supplement nutrition, they should be cooked and chopped and fed into the feed.
(3) Do not string piglets.
(4) The sow should drink enough water before giving birth, such as giving birth to a prolonged period of time, and the appropriate amount of warm water can be given in the middle.
(5) Sows who bite and lick their throats may wear mouth cages, take them off when they are fed, eat food and then wear them.
(6) Weed out sows that have given birth to several consecutive litters.
