Low temperature pig growth slow resistance poor winter pig house how to prevent cold and keep warm

The temperature in autumn and winter is low, the growth of pigs is slow, the feed reward is low, the resistance is decreased, easy to get sick, and the benefit of pig farm is poor. In order to ensure the normal and rapid growth and development of pigs, improve the feed reward and increase the income of raising pigs, it is very important for pig houses to keep warm.

Keep cold and warm in pig house

Overhaul: the thief wind invades the pig house and attacks the pig body, which will cause pig colds, pneumonia and other diseases. therefore, the pig house should be built in the high dry and sunny place. Before the beginning of winter, plug the voids on the north, west and east, and repair the roof and wall cracks in time. Windows and vents should be 1.5 meters from the ground to maintain a stable temperature.

Hanging straw curtains: the doors and windows of piggery can be covered with straw curtains or plastic sheets before winter to keep warm and protect against the cold. In the northwest outside the north wall of the piggery, the wind barrier wall or haystack made of straw is used to prevent the northwest wind from attacking.

Build plastic shed: plastic shed, low investment, high efficiency and convenient production. Generally speaking, farmers can raise pigs separately according to the enclosure model and build arched, ridged, umbrella-shaped or single-slope sunny sheds above the enclosure according to local conditions. Leave a movable ventilation window near the top of the south for temperature adjustment and ventilation. The temperature of the plastic shed can be increased by about 7 ℃, which is beneficial to the growth and weight gain of pigs.

Make grass mattress: before winter, add thick 15cm corn leaves or other hay on the pig bed, which can not only absorb moisture, absorb harmful gases, but also increase the temperature of the pig bed. The practice shows that the sawdust of thick 10cm is spread in the pigsty and the starter is added. After several days, the sawdust can be fermented at a temperature of 35 ℃, and the temperature in the house is increased. The sawdust washer can be used as crop fertilizer.

Anti-thief wind: the thief wind enters through the gap in the pig house and attacks the pig body, causing the pig to catch a cold, pneumonia and other diseases. Therefore, the leaks and cracks in the enclosure should be plugged and take time every day to check whether there are cracks or holes in the walls and roof of the piggery and whether the door curtains and curtains are hung.

Disinfection and immunity: some infectious diseases such as porcine contagious pleuropneumonia, porcine influenza, epidemic diarrhea have obvious seasonality, sudden changes in temperature and poor sanitary environment can be induced. In addition, in autumn and winter, try to avoid buying pig breeds from other places, so as not to cause infectious diseases. And the breeding of piglets in spring is better than that in autumn.

Meticulous feeding: when preparing pig diets, energy feeds such as sorghum and corn should be added appropriately. Feed should be fed with warm water after fermentation. Feed supply should be adequate, every night around 0: 00, plus feeding, in order to enhance the cold and disease resistance of pigs, and promote rapid growth.

Adding traditional Chinese medicine to pig feed: the traditional Chinese medicine of promoting blood circulation and removing blood stasis, invigorating spleen dryness and dampness, dispelling wind and dispelling cold can not only promote the rapid fattening of pigs, but also resist cold and prevent disease. Prescription: Hawthorn, Atractylodes, tangerine peel, betel nut, Shenqu 10 grams each, malt 30 grams, Sichuan dome, licorice, Schizonepeta tenuifolia, cypress kernel 60 grams each, Aristolochia mandshurica 8 grams, research end, mix a small amount of feed, feed once in the morning, once a week.
