Preparation and application of special compound premix for fermented feed

Abstract

The invention discloses a special compound premix for a fermented feed. The special compound premix is prepared from the following main components by weight percentage: 2-2.5 percent of fermented culture, 8-10 percent of enzyme preparation, 30-37.5 percent of fermentation promoter and 50-60 percent of feature pack aiming at different animals (piglets, middle and big pigs, sows, laying hens, dairy cows and fattening sheep). When the fermented feed is used in a large scale for a long time in daily ration of animals, the fermented feed is matched with the special compound premix to use, so that the normal supply of amino acids, vitamins and microelements for animal bodes can be ensured. Moreover, the premix does not contain hormones, antibacterial agents, antioxidants and flavoring agents, and the copper and zinc contents are lower than the national standard. The special compound premix has important meanings for providing safe meat, egg and milk foods, avoiding environmental pollution, realizing green no-antibiotic and hormone breeding, and ensuring the healthy and sustainable development of animal husbandry and aquaculture.

Description

technical field [0001] The invention relates to the field of additive premixed feed, and in particular provides a technology for preparing and using a compound biological premix special for fermented feed. Background technique [0002] Fermented feed belongs to the category of feed biotechnology. It is aerobic or anaerobic fermentation after mixing various conventional or unconventional feed materials to eliminate anti-nutritional factors and toxic and harmful substances, and improve the utilization efficiency of nutrients. The fermentation process will accumulate rich probiotics, enzymes, vitamins, polysaccharides and other biologically active substances to ensure the micro-ecological balance of the animal intestines and improve the immunity of the animal body.

AI Technical Summary

Problems solved by technology

[0003] When fermented feed is used in a high proportion of animal diets and fed for a long time, it is necessary to add an appropriate amount of premixed materials during the preparation of fermented feed to ensure the normal supply of amino acids, vitamins and trace elements in the animal body, otherwise it will affect animal production performance. Reduce farming efficiency

However, amino acids and vitamins are biologically active substances. During the fermentation process, biodegradation and transformation will occur. Inorganic trace elements will be partially transformed into organic trace elements during the fermentation process, resulting in changes in absorption efficiency. Only refer to national and industry standards for nutritional requirements And previous experience is not enough to ensure that animals get the right amount of nutrients when eating fermented feed
