Pig breeding equipment -- cold proof and temperature increasing technology in Piggery

In the actual winter pig feeding and management, to pay attention to the cold insulation measures in the pigsty, improve indoor temperature, reduce the consumption of pig body metabolism, in cold winter, not only does not affect the growth and fattening, but also promote the growth and fattening.
First, increase the feeding density of a pig is a "source", the higher the density, the higher the temperature. The sows per head, accounted for 4~4.5 square meters, a captive a nest; not pregnant sows per head accounted for 1.6 square meters, 4 square meters in 2~3 head; 6~8 months gilts per head accounted for 0.8 square meters, 4 square meters of captive 7~8 head. The above bars include eating, drinking and resting places. In the resting area (sleeping area), the method of lying full circle should be adopted, that is, the pigs can be filled in the sleeping area without leaving any gaps, and the sleeping area should be kept clean and dry.
Two, reduce the humidity of pig house, the humidity of pig house is bigger, the heat that pig body loses is greater, the pig feels cold more. In order to avoid moisture, fold to frequently change hay and dry soil, to make the pig manure fixed row, generally 4~5 times per day and night time row fecaluria, pig lying place can ensure no waste, keep dry. Due to the increase in the number of pigs in the winter urine, the humidity inside the house becomes larger. So, in addition to training pigs "three point positioning" (food, feces, urine bed fixed position), fed feed can not be too thin.
Three, to prevent drafts into pigs by thieves attack pens gap. When the pig is asleep, it can cause cold, pneumonia and other diseases. Therefore, to block the leak and break the good housing gap, house windows or vents be apart from the ground 1.5 meters above.
Four, the application of simple fold plastic greenhouses covered with plastic film can effectively improve Pingpen temperature above 7 DEG C, reduce cold stress, reduce energy consumption.
Five, for increasing the density of the grass in the grass at the same time the application of thick cushion ring, it is a effective way to winter moisture proof, bedding straw (wheat straw, rice straw and sawdust) sources, straw and pig manure fermentation of organic fertilizer used together. Methods using the pad grass ring is in the grass plate pig lying area 20~30 cm, grass board best brick cement bricks; the vertical brick on the floor under 5 cm, 19 cm on the ground with cement brick brick grass blocking plate 20~22 cm high, the pad join the grass lying area, prevent the straw scattered and pig shit in the area lying.
Winter cold, when the outside temperature is too low, the pig body in order to maintain normal body temperature, it is necessary to enhance the oxidation of substances in the body decomposition, heat generation, to supplement the body heat dissipation. Generally speaking, when the temperature of piglets is between 20 and 26 degrees Celsius, the consumption of metabolism is low and the growth and development are normal. However, the consumption of large pigs was lower at 15 and 20 degrees Celsius, and their normal growth was normal.
