Nowadays Pigs Nine Essentials
There are four ways to increase the temperature of a pig house and increase the temperature of the house. One is an open-type pig house covered with plastic film. It is best to cover the double-layer plastic film, although the cost is higher than the single-layer plastic film coverage, but the insulation effect is better. This method is suitable for fat pighouses and non-nursing sow houses; second is the boiler-type heating supply for closed pig-raising workshops; thirdly, heating and heat-supplying of plastic pigs for open-type pigskins; and the fourth is heating and heating of electric heaters. It is suitable for nursing sows. The exterior wall of the pig house should be thick, tight and the rear wall, gable, and front wall of the pigsty should be increased in winter. Piles of straw can be stacked, and clay can also be temporarily built. It is best to thicken the outer walls when the pig house is built. Obsolete pig houses must seal the wall, doors and windows of the gap. The floor of the pig house should be drained of the faecal sewage in time and cleaned. In order to facilitate drying, the piggery should be made of concrete floor. Additional beds in the pig stage, where conditions permit, it is best to use wood, bamboo, thick fiberboard and other warm bed, where no conditions can be laid cement prefabricated panels. Do not allow the pig to drink cold water. Warm the cold water and let the pigs drink it. The purpose of increasing the number of feedings to increase the number of feedings is to increase the feed intake relatively, so as to compensate for the weight loss caused by the body fat and muscle metabolic heat production caused by the low temperature. Where conditions permit, it is best to take free food. Feeding can be added once in the evening at regular feedings. Appropriately increasing the energy level in the feed can increase about 10% on the basis of the original feed energy level, the low point of the big pig, and the high point of the pig. Piglets can be supplemented with high-energy feeds for fats and oils. Big pigs can increase the amount of common energy feeds such as corn in batches. Appropriate increase in stocking density When the stocking density is high, the floor area of ​​each pig is reduced. When lying down, it can be warmly affixed to each other. At the same time, when the pigs are kept at high density, their body heat dissipation is also increased, which is conducive to raising the temperature inside the pig house. Increase the lighting area of ​​the pig house When building the pig house, it is necessary to consider the lighting area of ​​the pig house. Open pig houses should have a large open area; closed pig houses should have windows on the south wall and the top of the pig house to prepare for the installation of glass in winter.
