How to improve the survival rate of winter piglets

In winter, the temperature is low, and low-temperature frost often occurs, which is unfavorable to the survival of piglets. Therefore, we must strengthen the care and management of piglets in order to improve the survival rate.

1. Improve the environment of the pig house. In general, the temperature of piglets should be maintained at about 28-30°C within 3 days postpartum, and 25-26°C should be maintained within one week. Therefore, preparation must be done before the sow gets litter: spread a uniform layer of dry straw or soft dry grass on the ground of the barn cement, and then put a sack on it. Pighouse insulation conditions are not good, in winter when the best litter box insulation, that is, with a wooden box or thick bottom luggage covered with insulation materials for piglets rest. In cold weather or rainy weather, a 40 watt light bulb must be hung inside the box to increase the temperature and light.

2, to prevent dystocia or abortion. During the prenatal period of sows, sows should be sun-dried and exercised daily to increase their physical fitness and supplements. Pregnant sows do not feed sour spoilage feeds. When cleaning the pig house, do not hit the sow, nor can you use a sweeper or a stick to hit the sow. When sows are farrowing, they must not be separated from the human being. They must be kept both day and night so that they can always prevent coping with obstructed labor and prevent the sow from crushing the piglets.

3. Carefully take care of weak piglets. After the piglets are born, they can usually collect milk more than 10 minutes. However, the weak piglets are unable to find the teats in time because of weakness in their limbs. They are therefore unable to find the nipples in time. Therefore, they should be given artificial assistance in order to allow the weak piglets to eat colostrum within one hour after giving birth. After the sow has finished giving birth, the weak piglet should be immediately placed on the nipples in front of the breast to make it a habit, eat and drink, and strengthen the body. One week after the birth of the piglet, feed should be taken to prevent breast milk from being insufficient.

4, timely prevention of piglet disease. Understand and master the pig's coat luster, how much feed intake, tail swing, color and shape of urinary urine, sanitation of the anus, piglets are born about one month, three vaccines for swine fever, swine erysipelas and swine flu are needed To prevent the spread of piglet infectious diseases.
