There are skills in raising pigs to protect against cold in winter.

The temperature drops obviously in winter, pigs are very prone to disease, affecting the normal growth, if we can take effective methods to prevent cold scientifically, it can reduce the occurrence of various respiratory and intestinal diseases and promote the health and fattening of pigs. Here are several kinds of prescription for your reference:

First, before the beginning of winter, the whole doors and windows of the piggery are covered with plastic sheeting to keep warm and keep warm.

Second, add bedding: add sawdust, rice husk and hay 15cm ~ 20cm thick on the pig bed, which can also absorb moisture and remove moisture. Pay attention to check and update the wet hay frequently, and find that pig urine should be replaced with hay in time to keep the pigsty dry and comfortable.

Third, add bed board: in piggy stage, where there are conditions, it is best to use warm bed board such as wood board, bamboo board, thickened fibreboard and so on.

Fourth, increase the daylighting area of pig house: when the pig house is first built, it is necessary to consider the daylighting area of pig house. The open pig house should have a larger open area in case it is covered with plastic film in winter to facilitate daylighting. The enclosed piggery should reserve windows on the south wall and roof for the installation of glass in winter.

Fifth, increase the feeding density: if the scattered pigs are raised in groups, the number of pigs raised in the house can be increased by 30% to 50% compared with summer, and the temperature of the house can be increased by using the body temperature between pigs.

Sixth, provide high-quality ingredients: appropriately increase energy feed such as sorghum and corn or choose high-quality full-price feed produced by regular manufacturers.

7. Before weaning, piglets can build a small circle of 1m × 1m × 1m in the corner of the circle, with a wooden board or hay mat on the ground and an insulation lamp on it.

Do a good job of the above points, for the winter pig cold can play a vital role.
