We know that the nutritional value and utilization value of fermented feed is much higher than that before fermentation. The fermented feed has improved the value of agricultural and sideline products from various aspects such as palatability, detoxification effect, nutrient composition and digestibility, and has expanded its scope of use. It has also found a new outlet for feed resources. According to the law of conservation of natural energy, the total energy of fermented feed by microbial fermentation (life activities) will be reduced, but the energy that can be used by animals will increase. Let's take a closer look at the gains and losses of fermented feeds. 1 Fermented feed 1.1 Improvement of nutrient content The raw material of fermented feed is generally a by-product of agro-industry with low utilization rate. By adding a feed starter-Gembab's feed starter, the original protein and fiber are decomposed by microbial fermentation and self-propagation. After the use of new proteins, nutrients are improved. Fermentation can effectively reduce the crude fiber of the base material. Research shows that the general fermentation level can reduce the crude fiber of the base material by 12%~16%. Tu Guoquan and others used composite bacteria preparations to ferment roughage containing feather keratin protein and brewer's gruel. After fermentation, crude protein content increased by 20.15 % and crude fiber decreased by 46.3 %. In addition, various growth-promoting factors such as organic acids, B-vitamins, and unknown growth factors can be produced during microbial fermentation, and different growth factors produce different levels of growth factors. 1.2 Effective Detoxification Microorganism Fermentation feed has the functions of adsorbing mycotoxins, degrading gossypol, anti-nutritional factors and other harmful substances, and creatively adding high-activity cellulase. The golden baby starter can effectively reduce the toxin content in the feed, which is related to the metabolism or metabolites of the microorganism. Kuo Yu - Haey et al. Production of protein feed using low-toxic fermentation of legumes of Aspergillus oryzae and Rhizoctonia solani and fermentation of neurotoxin b-ODAP (3-N-glycol-L-2,3-diamino The removal rate of propionic acid is up to 52.4%~82.2%, and the detoxification effect is significant. 1.3 Improved palatability and digestibility The fermented feed has a natural fermented aroma, which has a good stimulating effect and can significantly improve the palatability of the feed. After the feed is fermented by microorganisms, some starch and fiber are degraded into small molecules of sugar or acid, and some of the proteins are degraded into peptides or amino acids, similar to the effect of pre-digestion in vitro. In addition, the microbial protein produced by microbial fermentation is more easily digested and absorbed by animals. Cai Yong used composite microbial preparations (Lactobacillus, Bacillus, Yeast, Geotrichum candidum, and photosynthetic bacteria) to conduct mixed solid-state fermentation of waste blood meal, leather powder, sesame meal, cottonseed meal, horn powder, and corn meal. The protein digestibility increased from 75.9% before fermentation to 91.2% after fermentation. 2 The loss of fermented feed should always be divided into two. The gains must be lost, and the fermented feeds are the same. On the one hand, the carbohydrates in the raw materials are oxidized into water and carbon dioxide during the fermentation process, which is accompanied by the generation and emission of large amounts of heat, and can always be reduced. Therefore, as long as the microbial fermentation, its total energy value must be reduced. The total energy loss of the general fermentation feed is not much, about 5%. On the other hand, the temperature of sterilization and drying of fermented feeds is relatively high, and high temperature has a certain destructive effect on vitamins and minerals. Therefore, when preparing concentrated feed, it is necessary to supplement single vitamins and certain trace elements.
