Raising pigs in plastic-covered greenhouses in winter saves feed and prevents disease

In winter the weather is cold and temperatures are low, which is extremely unfavorable to the health and growth of pigs, especially pregnant sows and piglets. So what method can be used to solve the problems brought by the season? The best method is to raise pigs in a plastic-covered greenhouse, covering the open side of the pig house with plastic film to raise the temperature inside. Generally speaking, the temperature suitable for the growth and development of fattening pigs is 14-23°C, with 16-18°C being the best. The temperature suitable for the growth and development of young pigs and piglets is somewhat higher.

In winter, for about 4-5 months of the year, the temperature is lower than what pigs need for growth, and January is the coldest. At present, pig houses in rural areas are mostly open-style, and in winter the temperature inside the house is basically the same as outside. This not only affects the growth of the pigs, but also, because the pigs lose a large amount of body heat, they eat more feed, which consumes more feed and raises the cost of raising them. Therefore, raising pigs in a plastic-covered greenhouse can save costs.

The method is: cover the open-air part outside the pen with plastic film. Depending on the eaves of the pig house and the pen wall, the plastic film can be covered directly or on wooden sticks, and the covering should be as tight as possible. After covering, the humidity inside the pen can easily become too high, so the enclosure wall should have urine drainage openings, manure should be removed promptly, and the cover should be opened and closed at the proper times for ventilation, so as to keep the inside of the house clean and hygienic. For the style of the pig house, a single-row, semi-enclosed pig house with a corridor is generally used. In this kind of pig house, a work corridor 80 to 100 cm wide can be set up along the north side. Its advantages are ventilation and air permeability, heat preservation and moisture proofing, fresh air, simple structure, low construction cost, and convenient work.
