Safe wintering of live pigs "six measures"

The optimum ambient temperature in the pig house is 15°C to 25°C. Below 5°C or above 30°C, the growth of pigs will be affected and even diseases will occur. Therefore, the winter response pigs adopt special feeding and management methods. Specifically, it should start from the following six aspects:

To improve the environment before the cold arrives, a comprehensive inspection of the pig house and the surrounding environment should be conducted to repair the bad, dangerous and leaking pig houses in a timely manner. The piggery can be placed in a spacious and ventilated place with a sack sheet or straw curtain. The height of the sack curtains is a pig bite. It is not appropriate; inside the circle, such as rat holes, cracks, gaps, broken tops and other tuyere should be plugged tightly to prevent "dragon style" and "thief wind" from invading the pig body; put the hay on the pig's sleeping bed, give the pig's cool ring Covered with plastic film, this is one of the most important measures to prevent cold and keep warm.

Moisture-proof and moisture-proof pigs prefer to dry and fear moisture. Air is a kind of heat-conducting material, and the more humid it is, the stronger its thermal conductivity is, and the faster the heat inside the hog body is distributed. When the pigs are chilled, they will squeeze each other, causing crushing or crushing, and even biting. The manure in the pigsty must be cleaned, and attention should be paid to training pigs to defecate urine and have a dry place. Always change the bedding to keep the grass clean. In sunny weather, keep the pig house in a dry environment to facilitate the healthy growth of pigs.

To adjust feed formula for winter pigs, it is necessary to increase corn and other energy feeds by about 10% under the premise of stable protein content. If necessary, animal and vegetable oils can be added. Experiments have confirmed that adding 2% to 3% of animal and vegetable fats and oils in the diet can increase pig weight gain by 12% to 15%, and save 8% to 10% of feed per kilogram of weight gain.

Increased density When the rearing density is high, each pig's floor space is reduced. When lying down, they can be warmly affixed to each other. At the same time, when the breeding density is high, their body heat dissipation is also increased, which is conducive to raising the temperature inside the house. In winter, the number of pigs increased by 1/3 than usual, so that each pig occupies an area of ​​about 0.6 square meters. However, the stocking density should not be too large to avoid fighting between pigs.

Supply of hot water for winter raw food and feed for pigs, available dry powder, hot water can also be used to mix, humidity in hand into a group, landing that is appropriate to scattered, and to be immediately mixed feed. To ensure the supply of clean hot water, pigs have a great demand for water, and the need for water is very important. If you lose 10% of the body's moisture, the pig will feel unwell; if you lose 20% of the body's moisture, it will die. Therefore, it is necessary to replenish the pig's water from time to time. If there is no water in the lap, the pig will eat snow, eat ice cubes and drink urine. This will inevitably cause digestive diseases or other diseases, so we must constantly provide warm and clean food. Drinking water.

The purpose of increasing feeding times is to increase feed intake relatively. Where conditions permit, it is best to take free food. Feeding can be added once in the evening if regular feedings are used.
