How to raise pigs in the cold season?

In the cold season, in order to keep the pigs warm, an energy feed can be added to the feed, and corn can be used as a substitute for bran in the feeds of the formulated pigs and nursing sows to increase the pig's energy level.

In the autumn when raising pigs, in addition to strengthening the conventional feed management, but also do a good job of pig feed reserves and fattening fattening work. In the fall, sweet potato, Chinese yam, peanut pods, bean stalks and other comminuted fermentations are all good pig feeds. Potato tubers, legume pods, etc. can be dried and crushed to feed the pigs.

In the autumn, the pigs adopt the method of feeding raw materials and feeding water separately. The powdered ingredients are prepared by adding water at a ratio of 1:1-1:1.5. Establish a regular and quantitative feeding system. In order to improve digestion and improve feed efficiency and growth rate, pigs in the fall season can be fed three times a day. In addition, in autumn pigs, the appetite of pigs is generally the highest in the evening, followed by morning and the weakest at noon. The amount of feed each time during a day can be roughly distributed at 35% in the morning, 25% at noon, and 40% in the evening.

Second, the piggery measures:

1. Renovate the pig house and block the area where the column is leaking. Use the grasshopper or plastic film to prevent the cold wind.

2. Keep hay in the pig house and do not let the grass be damp.

3, increase the breeding density, so that the pigs sleep, can warm each other, but also increase the column temperature. Feed more heat-intensive feed to increase calories in the pig.

4. In order to reduce the ammonia concentration in the pig house, the protein level in the feed can be appropriately reduced.

5, conditional farmers can build a greenhouse in the corner of the pigsty shelter, the size of the greenhouse can be determined according to the number of pigs.

The method is: build a wall about 1 meter high, leave a small door for pigs to come in and out freely, cover the grass with straw in the upper part, and spread hay on the inside. When the temperature is low, the pig will automatically enter the incubation room to avoid the cold.
