The new direction of feed fermentation

Fermented feeds start with fermented wet materials. With the development of technology, fermentation of agricultural and sideline products and waste from the food industry has not only expanded feed resources, alleviated the problems of livestock and livestock, but also increased the use value of these agricultural industry by-products. After the feed ingredients are fermented, they are usually formulated as concentrated feeds, or they can be fed into the full-priced feed as a kind of ingredient. Fermented feeds have a good effect, and the price is cheaper than soybean meal, fish meal and other raw materials, so they are quickly welcomed and popularized by people. Full-price fermented feeds are similar to the second one in that full-nutrified non-drug compound feed is added to microbial inoculants (such as garpy starter), water, and bacteria-enriching bacteria, and mixed and then subjected to anaerobic or aerobic fermentation at an appropriate temperature. The resulting functional feed can be directly fed to animals after fermentation. The full-price fermented feed has obvious functions of promoting growth and preventing diseases, and is a new direction of feed fermentation.

1. The development of fermented feed

The use of fermented wet feeds has been widely used since the mid-1980s. The early practice was mainly through the microbial fermentation to make some industrial and agricultural waste (waste, wastewater, high cellulose, miscellaneous clams, etc.) to be fully utilized to expand the feed resources. In the later stages, the feed ingredients (corn, soybean, etc.) are gradually fermented and used in combination. Compared with single fermentation raw materials, the common practice at this stage is to directly ferment the full-price feed and then directly feed it. Today, at least 50% of the pigs in the Netherlands use micro-ecological fermentation feeds, in Denmark more than 30% of sows use fermented feeds, and more than 70% of sows use during lactation. In EU countries, the major raw materials for the fermentation of full-price feeds and feeds are mainly tended to be used.

2. Characteristics of Full-Price Fermented Feed

The full-price fermented feed is prepared by adding the entire price of the prepared material, including energy ingredients, protein raw materials, trace elements, etc., to the feed, or the purchased full-price feed (without medicine) as a substrate, adding microbial inoculants, water and Enrichment base, mixed with anaerobic or aerobic fermentation of functional feed at appropriate temperatures. Full-price fermented feed can not only fully meet the nutritional needs of animals, but also increase the content of various digestive enzymes such as organic acids, vitamins, peptides, small peptides and amino acids, and is rich in a large number of probiotics. It has obvious biological effects such as promoting growth and preventing diseases, has good control effect on intestinal diseases, and improves the palatability of feed, improves animal feed intake, and saves production costs. In addition, it should be noted that full-price fermented feeds reduce the overall cost through the addition of water, and improve the digestion and absorption rate of the feed through the fermentation process, but this part of the water does not produce nutritional value, so its added amount is limited. Excessive addition will dilute the nutritional concentration of the feed.

3. Factors affecting the full-price feed fermentation effect

The choice of fermentation process and strains are the key factors influencing the use of full-price fermented feeds and are directly related to the success of fermentation. The general fermentation process is mainly solid fermentation and liquid deep fermentation. Solid-state fermentation technology is simple, extensive process, low investment, high yield, but labor intensity, it is difficult to achieve accurate measurement and automation; liquid fermentation has a short fermentation time, high efficiency, suitable for industrial production and easy to control conditions, but the advantages of investment Larger, higher production costs. At present, there are many kinds of fermenting bacteria in the market in the form of compound bacteria.
