This paper introduces the advantages of raising black fragrant pigs in dry fermentation bed.

Xiang Pig, also known as "Mini Pig", is famous for its small body, precocious maturity and delicious meat. The fragrant pig skin is thin, the carcass is lean, the muscle is bright red, the fragrance is sweet, and the nutrition is rich. The protein content of the meat is as high as 21.8%, which is higher than that of the ordinary pig. The protein content is as high as 21.8%, which is higher than that of the ordinary pig. The fat is only 18.86% and 28.10% of that of the ordinary pig, and the calorie is also low, which is 60.85% and 76.1% of the ordinary pig.

In addition, it is also rich in essential amino acids and trace elements. Therefore, even if the price of fragrant pork is very high, it is still very popular. In particular, pigs raised in dry-spread fermentation beds have better meat quality, stronger flavor, and are more favored by people. According to the person in charge of the Tianjin beneficial bacteria Pig farming Cooperative, since their cooperative used the dry spread fermentation bed farming technology, not only raising pigs is more labor-saving and profitable, but also more ecological and more environmentally friendly. The benefits of raising black Xiang pigs in dry-spread fermentation bed are shown in the following aspects: 1. Deodorization, environmental protection, zero emission incense pig feces and urine under the action of functional bacteria, part of the degradation into odorless gas is discharged, such as water vapor and CO2; the other part is converted into crude protein, bacterial protein and vitamins and other nutrients. The pollution of feces and urine to the ecological environment is eliminated from the source, so that the enclosure has no odor and achieves zero emission. 2. Energy-saving and grain-saving input less heat produced by fermentation bed fermentation, no matter the surface temperature is kept at more than 20 degrees in winter and summer, which can save more than half of coal and electricity. Feces, urine and bedding materials are degraded to form bacterial proteins and a variety of beneficial substances are eaten by Xiang pigs under the action of beneficial bacteria, which not only meets the habit of Xiang pigs loving arch food, but also meets the requirements of Xiang pigs to eat more roughage, and the recycling of waste can save about 20-30% of feed. 3. The fermentation mattress material for disease resistance and healthy growing pigs eliminates the odor substances in feces and urine through physical adsorption, chemical neutralization and biochemical action in the fermentation process. Xiang pigs live in a large number of beneficial bacteria for a long time, and the environment in the enclosure is fresh. It obviously improves the disease resistance of pigs, and rarely causes diseases (for example, the fragrant pigs raised on the fermentation bed, basically free of foot-and-mouth disease or occasional infection will soon recover. Unlike the cement ring, which continues to spread viciously, it grows healthily, saves 5-8 yuan in medical expenses per pig, grows smoothly, and can get out of the pen ahead of time. 4. Water-saving workers easily raise fragrant pigs in a dry fermentation bed, and the feces have been decomposed and transformed by Jinbao beneficial bacteria, so they can save more than 90% of water without cleaning dung or punching circles. The work originally done by three people can now be easily done by one person, saving time and effort. 5. Improve the quality and price, raise Xiang pigs in a high dry fermentation bed, let Xiang pigs live on a soft and comfortable "bed", eliminate the tension of Xiang pigs on the cement floor, grow lively and healthy, use little or no drugs, and greatly reduce or even eliminate drug residues, so that the meat quality of Xiang pigs is better, the taste is better, and the price is higher.
