Six precautions for raising pigs in winter

Prevent cold food

In winter, pigs eat nothing more than to keep out the cold and gain weight, while sows want to ensure the normal growth and development of their fetuses, so it is necessary to increase energy feed appropriately when blending. Increase its ability to keep out the cold. When mixed with feed, it is best to feed raw food and dry feed, and the water temperature should be about 25 ℃ when a small amount of water is needed. If you adopt the method of balance feeding, the drinks should be warm and hot, and should be added less frequently to prevent cold and frost.

Anti-cold drink

Pigs have a great demand for water, and the demand for water is very important. If there is no water in the circle, the pig will eat snow and ice; drink urine, which is bound to cause digestive tract diseases or other diseases. Therefore, it is necessary to constantly provide warm and clean drinking water to prevent both patients and pigs.

Guard against wind attack

The winter piggery must block the wind tunnel, hang grass curtains and paste windows to prevent the rat holes, cracks, gaps, broken tops and other tuyere blowing into the "through the hall wind". Ventilation holes can be left at least 1 meter above the ground.

Moistureproof

Pigsty drying is one of the main measures to ensure the health of pigs. Air is a kind of heat conducting material, and the wetter it is, the stronger its thermal conductivity is. The pig body is cold, crush injury and even death, epidemic disease is also easy to occur. Therefore, the ring should be padded frequently to ensure dryness, and pay attention to training pigs to defecate and urinate at a fixed point, with a dry lying place.

Anti-low temperature

The optimum temperature for pig growth is 15 ℃ ~ 25 ℃. The temperature of normal growth should generally be above 8 ℃, in order to ensure the normal growth and development of pigs, the best way is to use a warm shed, that is, to cover the roof with a thicker plastic film, covering a slope of about 30 degrees to facilitate daylighting, the circle temperature is too high at noon to vent and ventilate, and it should be cleared in time after snowing.

Prevention of epidemic disease

Due to the low temperature and dry air in winter, digestive tract diseases, respiratory diseases and infectious diseases of pigs are very easy to occur. in order to develop healthily, pig production must always keep the pigsty clean, clean and hygiene. regularly and irregularly carry out pen brushing and disinfection or spray disinfection, pigs should be vaccinated, and commonly used drugs should be available to ensure early isolation and early treatment of diseases.
