The main reason for the popularity of raising pigs in greenhouses is the low cost, because greenhouse piggery is much cheaper than reinforced concrete piggery. It is also much more convenient to build. It can be said that the construction cost has fallen off the cliff. Therefore, it has been popularized in rural areas. The only drawback is that a greenhouse can raise 100 pigs, only large-scale pigs, and small-scale pigs are not suitable. Raising pigs in greenhouse has three advantages: constant temperature, warm in winter and cool in summer, simple operation and convenient management, and high meat yield. These advantages will be explained in detail below:
1. Raising pigs in a greenhouse has the advantages of being warm in winter and cool in summer: because the greenhouse is a plastic greenhouse, it is translucent. In cold winter, sunlight will shine into the room through the plastic film to raise the indoor temperature, so the greenhouse is very warm in winter. In summer, a layer of black heat-absorbing plastic film can be covered outside the plastic shed, which can not only shade the light, but also absorb heat. In addition, there are ventilation pipes and ventilation equipment in the pigsty, so the pigsty is very cool in summer. Therefore, the temperature of raising pigs in greenhouses is constant, it is warm in winter and comfortable in summer. Pigs can eat and sleep in the greenhouse.
2. Raising pigs in greenhouses is simple to operate and convenient to manage: firstly, the temperature of raising pigs in greenhouses is constant, so it is not necessary to adjust the temperature frequently. Secondly, unlike raising pigs indoors, a pigsty needs several workers to work together. The pigs in the greenhouse are all taken care of by one person. Therefore, the greenhouse has the advantages of simple operation and convenient management. Therefore, the labor cost is saved.
3. The advantage of raising pigs in greenhouse is high meat yield: a pig shed of 180 square meters can raise 100 pigs. A greenhouse pig farm has 20 greenhouses, which means that at least 2000 pigs can be raised. This is equivalent to the pig production of a medium-sized pig farm. Coupled with the comfortable and comfortable environment for raising pigs in greenhouses, pigs grow well. So thousands of pigs can be produced every year. The meat yield is very high and the economic benefit is very considerable.
