If the feeding and management of pregnant sows is improper in the summer, it will easily lead to impediment to the growth and development of the fetus, and even cause miscarriage and disease. Therefore, we must pay special attention to strengthening the feeding and management of pregnant sows, specifically to pay attention to the following five points:
prevent disease
There is more rain in summer and the grasses are easily spoiled and rotted. Therefore, in the rearing process must be "five net": the material expected net, grass net, net water, net net, pig net, to prevent pathogenic microorganisms against the pig. At the same time, pay attention not to feed cold and cold feed, such as dew wet grass; pay attention to changes in the weather to prevent pregnant sows from catching colds and colds; don't crowd, run, kick, and fight when feeding and grazing pregnant sows.†Cold whip" to prevent miscarriage due to reflex contractions in pregnant sows' wombs.
Increase nutrition
In summer, in addition to feeding quality sows for sows, appropriate amounts of protein, vitamins, and mineral feeds, such as fish meal, blood meal, bean cake, bone meal, stone meal, etc., must be added, and sufficient energy feeds such as corn and sorghum stalks should be supplied. In order to ensure that pregnant sows eat enough to drink and full nutrition, the fetus can grow and develop normally. Otherwise, pregnant sows may suffer miscarriage due to malnutrition, stillbirths, or congenital stunting of young pigs.
Avoid fatigue
Excessive fatigue and excessive oxygen consumption in pregnant sows can easily lead to accumulation of carbon dioxide in the body, and the fetus can suffer miscarriage due to lack of adequate oxygen and nutrients.
Control drinking water
Pregnant sows should be clean drinking water, can not fasting drinking water, pay special attention to prevent binge drinking. Because binge drinking easily lead to pregnant sows gastrointestinal spasm, uterine contraction, resulting in rupture of the fetal membrane blood loss and miscarriage.
Strengthen management
In summer, fresh grasses have high water content. Therefore, when pregnant sows are fed, fresh grass should be mixed with hay. Otherwise, pregnant pigs can easily cause diarrhea and even miscarriage. If pregnant gilt diarrhea is found, it can be fed in a timely manner with the fried sorghum and evenly mixed in the feed, 0.5 to 1 kilograms each time, generally 2 times can be effective. In addition, the summer temperature changes rapidly, we must pay special attention to strengthen the management of pregnant pigs to prevent colds and complications of pregnant pigs.
