In the actual feeding and management of winter pigs, it is necessary to pay attention to the cold insulation measures of the pig house, increase the temperature inside the house, and reduce the metabolic consumption of the pig. In the cold winter, it will not only affect growth and fattening, but also promote its growth. Develop and increase phlegm.
First, increase the breeding density A pig is a "heat source", that is, the greater the density, the higher the temperature. The farrowing sows have 4 to 4.5 square meters per head and raise a nest in one circle. The empty pregnant sows have 1.6 square meters per head and 2 to 3 heads at 4 square meters. The reserve pigs at 6 to 8 months old account for each head. 0.8 square meters, 4 to 8 square meters of captivity 7 to 8. The circle includes eating. Drink water, rest place, in the rest place (sleeping area) should adopt the method of lying full circle, that is to say, in the lying area, the pig can be full, leaving no gaps, but also to keep the sleeping area clean and dry.
Second, to reduce the humidity in the pig house The higher the humidity in the pig house, the greater the amount of heat dissipated by the pig and the colder the pig feels. In order to prevent moisture, the ring bench should be frequently used for changing hay and dry soil. Regular defecation and urine excretion should be performed regularly. Normally, 4 to 5 times per day and night, regular excrement of urine, where the pig lies, can ensure no excrement and dryness. Due to the increased number of urine litters in winter, the humidity in the homes has increased. Therefore, except for the “three-point positioning†of the training pig (feeding, excrement, urination, sleeping at a fixed position), the feed should not be too diluted.
Third, the anti-thief wind thief wind enters the pig body through the gap in the pen. When the pig is asleep, it will cause colds, pneumonia and other diseases. Therefore, to plug the leaks and crevices of the sheds, the windows or ventilation holes of the shed should be more than 1.5 meters above the ground.
Fourth, the use of plastic greenhouses simple housing covered plastic film, can effectively improve the pighouse temperature above 7 °C, reduce cold stress and reduce energy consumption.
Fifth, the use of thick mats to increase the density of bedding grass, it is an effective method of moisture insulation in winter, bedding (grass, straw, sawdust crumbs) a wide range of sources, run out of grass and pig manure fermentation together organic fertilizer. The method of using the bedding and laying the grass is to put a 20- to 30-cm turf-bearing board in the piglet lying area, and the turf-proof board is preferably made of brick and cement; the vertical brick is placed 5 centimeters below the ground, and the remaining 19 centimeters are on the ground. , Bricks with a height of 20 to 22 cm will be built with cement and the grass will be added to the lying area to prevent the bedding from spreading and the pigs to pee in the lying area.
In winter, when the outside temperature is too low, the pig body must strengthen the oxidative decomposition of the body material to generate normal heat, so as to supplement the loss of body heat. In general, when the temperature around the piglet is 20°C to 26°C, the metabolic consumption is low and the growth and development are normal. However, large pigs have lower metabolic consumption from 15°C to 20°C, and increase their normal levels.
