Benefits and production techniques of feeding pigs with fermented feed
The so-called fermented feed is the fermentation of various green and rough feeds through certain beneficial microorganisms, making them a kind of feed that is sour, sweet, soft, cooked, fragrant, and suitable for pigs. First, the benefits of feeding pigs with fermented feed 1. Expand the 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, and sweet potato vines. In the past, they were rarely used for feeding pigs, or they were thought to be unable to feed pigs. In fact, these raw materials are pulverized and fermented and become pig-loving feeds. This greatly expands the pig's feed source. 2. Save 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 heavily and use crude and green feeds. In this way, the consumption of fine material is saved, the feeding cost is greatly reduced, and the economic benefits of raising pigs are improved. 3. 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 substances in feed into simple, easily digestible substances. Therefore, crude and green feeds can be fermented to increase their nutritional value. Pigs grow fast after eating. 4. Improve pig health and reduce disease. 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 proved that after pigs feed the fermented feed, common diseases such as asthma and gastrointestinal diseases 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. Second, the production of fermented feed technology There are many types of feed fermentation, and only one commonly used fermentation method is now described, namely the non-quenched saline fermentation feed method. Take 50 kg of dried raw materials, about 0.75 kg of salt, and about 50 kg of water (how much water depends on the amount of water absorbed). After dissolving the salt in water, stir the ingredients evenly with salt water. It is advisable to hold the water between the fingers and pinch the wet and dry hands, and then put them in the cask or cylinder. Use a broken sack or a straw curtain. Cover it for fermentation. During the fermentation process, it is necessary to grasp the feed temperature, and the feed temperature should gradually rise to 45°C. If it is at 45°C, it needs to be slightly pressurized and covered with a plastic sheet to force it to cool down. After more than one day of natural fermentation, the pigs can be fed if they are sour, sweet, soft, cooked, and aroma-tasting. Cold salt water is used in summer, warm salt water is used in spring and autumn, and in the winter below 0°C, hot salt water is used at 60-80°C. When loading into the tank, feed temperature should be 40 °C, not less than 30 °C. The well-fermented feed is tightly covered with a plastic cloth and can be stored for 1 week.
