The so-called fermented feed is a variety of green, rough feed, through the fermentation of certain beneficial microorganisms to make it a good fit, easy to digest feed. Feeding pigs with fermented feeds has four major benefits.
First, a wide source of feed. There are a large number of agricultural and sideline products in the vast rural areas of China, such as corn stalks, wheat straw, wheat bran, rice straw, rice hulls, peanut shells, sweet potato pods, etc. In the past, they were rarely used for feeding pigs or for feeding pigs. However, after crushing and fermentation, it becomes a favorite feed for pigs, which greatly expands the feed source for pigs. It is especially suitable for farmers and specialized household pigs.
Second, save fine material. During the fermentation process, roughage and green-green feed produce some organic acids, alcohols, and esters through the metabolism of microorganisms. The taste of the feed has been improved, allowing pigs to feed in large quantities and use crude and green feeds. Material consumption. In this way, the cost of feeding is reduced and the economic benefits of pig raising are increased.
Third, faster weight gain. Raw and green feed during the fermentation process, due to the continuous production of heat by microorganisms, so that the feed softens, produces a certain acid and aroma, improved feed compatibility, so that pigs like to eat, promote the secretion of digestive juice, is conducive to digestion and absorption. Moreover, due to the proliferation of microorganisms, the microorganism itself is rich in protein and vitamins, and thus enriches the nutrients in the feed. At the same time, because microorganisms contain many enzymes that break down starch, protein, fat, and other substances, it is possible to decompose and transform some difficult to digest and absorb substances in feed into easily digestible substances. Therefore, crude and green feeds can be fermented to increase their nutritional value. Pigs grow fast after eating.
Fourth, improve pig health. Fermented feed contains the necessary protein, vitamin B family and enzymes necessary for the normal physiological function of the carcass, which can improve the health of the pig and increase the disease resistance. Practice has shown that after feeding pigs, some common diseases such as asthma, gastrointestinal diseases, etc. have been reduced, boar sexual libido is high, sows have normal estrus, litter size is healthy, milk production is high, and piglet mortality is reduced.
