To do a good job of raising pigs in winter should focus on the issue of protecting the cold. The following nine main methods must be mastered. 2. The outer wall of the pig house should be thicker and tighter in the back wall, gable and front wall of the pigsty to increase the insulation facilities in winter. For this purpose, crop stalks can be stacked and adobe can 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. 3. 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. 4. Additional beds are provided at the pig stage. Where conditions permit, warm sheets such as wooden boards, bamboo boards, thick fiberboards, etc. are preferred. Precast concrete boards can be laid without conditions. 5. Do not allow the pig to drink cold water. Warm the cold water and let the pigs drink it. 6. 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 fat and the intramuscular metabolic heat production of the pigs caused by the low temperature. Where conditions permit, it is best to take free food. Feeding can be added at night in places where feeding is scheduled. 7. Moderately increased energy levels in feed can be increased by about 10% based on the original feed energy level. The big pigs are low and the pigs are high. 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. 8. 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 is also increased, which is conducive to raising the temperature inside the house. 9. 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. The open-type pig house should have a large open area in order to prepare the winter covered plastic film for easy lighting. Closed pig houses are to be reserved in the south wall and the roof to prepare for the installation of glass in winter.
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

1. There are many ways to increase the temperature of a pig house and increase the temperature of a pig house, but there are four simple, economic, and practical methods. 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 approach is suitable for fat and non-lactating sows. The second is the boiler-type heating supply in closed pig-raising workshops. Third, the open-type heating heating pigs and plastic film cover. Fourth, heating heating plus electric heater, suitable for nursing sows.
