Three Ways to Develop Economical Pig Raising Model

China is a large pig-raising country, and pig-raising takes up a large amount of resources and energy. today, vigorously advocating the construction of a conservation-oriented society, promoting energy-saving pig-raising is the development direction of our country in the future. here are several ways to raise pigs.

1. It is recommended to raise pigs to save concentrate

At present, the way of "corn + additive" is mostly used in the feed of intensive pig farming in our country. Although this kind of diet has the advantages of simple configuration, reasonable nutrition and relatively low meat, it needs a lot of corn and soybean meal to be imported from abroad. At present, some places have tried some green feed to replace concentrate feed to feed pigs, such as American chicory, rosin grass, alfalfa and so on. According to the experiment of breeding livestock farm in Dandong City, Liaoning Province, each pig was fed 77.5kg of American chicory and 214.5 kg of concentrate, and the income of each pig was 32.92yuan more than that of the control group. The yield of American chicory was 6000 kg, and the cost per kilogram was about 0.07yuan. The use of rosin grass and alfalfa also has economic benefits, and these experiences are worth popularizing.

two。 Reform the design of pig house and reduce the cost

The ventilation and warmth of pig houses are a pair of contradictions. in winter, some pig farms, especially in the north of the Yangtze River, put too much emphasis on warmth, closing doors and windows, covering ceiling roofs or plastic sheets, raw coal stoves in pig houses, and so on. as a result, although the temperature increased, the air quality in the house became worse, and a large amount of toxic and harmful gases such as carbon dioxide, carbon monoxide and ammonia exceeded the standard. The air is harsh, sows, piglets cough and other respiratory diseases, at the same time, due to the increase in humidity, in high temperature and humidity conditions, bacteria are easy to reproduce, resulting in piglets prone to diarrhea and other diseases, the effect is counterproductive. The new scheme to reform the pig house warmth is to distinguish the pig house temperature from the piglet incubator temperature. Pig farm power grid. The temperature of pig house can be decreased properly, while the temperature in incubator is kept at about 30-32 ℃, and it can be decreased appropriately with the increase of piglet age. The temperature of the nursery is only 2024 ℃. Therefore, the ceiling should be used in the delivery room to add adjustable roof ventilation, in the nursing column to set up incubators, the use of infrared or electric pad.

3. Reforming the Technical Scheme of sewage treatment in Pig House

The dung, urine and sewage of the intensive pig farm are treated by dry dung cleaning method, that is, manual manure cleaning is adopted, the feces and urine are separated in the pig house, and the feces are transported to the dung yard by trolleys for processing, and the indoor shallow sewage ditch is used on the floor of the pig house to reduce the water used to wash the ground. Although this scheme increases labor costs, it overcomes the shortcomings of the "water flushing method". The daily water consumption of pig farms can be greatly reduced, and the discharged sewage can be treated more easily; the quality of organic fertilizer produced by this method is higher, and the income of organic fertilizer can be equivalent to paying the wages of dung removal workers; the investment of the sewage tank is saved, the area is small, and the daily maintenance cost is low. Another important point in the pigsty design is to separate the sewers from the rain sewers, which can greatly reduce the amount of sewage.
