Preparation methods of animal active microecological fermented concentrated feed and compound feed

Abstract

The invention provides a preparation method of an active microecological fermented concentrated feed. The microecological fermented concentrated feed comprises the following components in percentage by weight: 1.5-5% of wheat bran, 70-90% of bean pulp, 3-5% of cottonseed meal, 5-8% of rapeseed meal, 3-6% of rock flour, 2-3.5% of calcium hydrophosphate, 1-2% of table salt, 0.3-0.7% of trace elements, 0.05-0.1% of compound vitamin, 0.5% of cane sugar prepared by the traditional method and 0.2% of fermentation promoter. The preparation method of the microecological fermented concentrated feed comprises the following steps of: 1, activating strains and preparing disinfectant fluid; 2, mixing the activated strains and the disinfectant fluid with the components, filling the mixture in a fermentation packaging bag and heat-sealing the packaging bag; 3, fermenting for 3-15 days at normal temperature to obtain the finished microecological fermented concentrated feed. In addition, the inventionalso provides a preparation method of an active microecological fermented compound feed and manufacture (preparation) methods of a fermentation packaging bag, fermentation strains and a strain growthpromoter used in the preparation process of the active microecological fermented concentrated feed. Due to adoption of the technology disclosed by the invention, namely a bidirectional-breathe feed packaging fermentation technology based on the designs of the fermentation strains, the strain growth promoter, the fermentation packaging bag and the feed formulas and combining anaerobic fermentationand aerobic fermentation, the prepared feeds have good palatability, high nutritional value and good animal feeding effect and are novel safe feeds without medicines such as antibiotics, hormones andthe like.

Description

technical field [0001] The invention relates to a feed and a production method thereof, in particular to an animal active micro-ecological fermentation concentrated feed and compound feed and a production method thereof, belonging to the technical field of feed microorganisms. Background technique [0002] Since the rise and development of my country's feed industry in the late 1970s, it has experienced the initial stage of entrepreneurship, the stage of rapid development, and the stage of integration and upgrading, and has achieved great achievements. From 1980 to 2007, the output of feed products increased from 1.1 million tons to 123.31 million tons, an increase of 112.1 times in 27 years, with an annual increase rate of 19.1%; the output value of the feed industry increased from 111.9 billion yuan in 1990 to 3335 million yuan in 2007. billion. With the development of the feed industry, the potential safety hazards of feed products, especially feed products in my country...

Problems solved by technology

Most of the above-mentioned fermentation strains are composed of photosynthetic bacteria, bacillus, lactic acid bacteria, yeast and filamentous fungi (or several of them), most of which are directly isolated from the natural environment or animals, and very few sources It is suitable for traditional breeding (natural selection, mutation breeding) and directional breeding (cross breeding, molecular breeding); this type of strain is due to the preservation of activity and fermentation activity of some strains (such as photosynthetic bacteria, lactobacillus and bifidobacteria, etc.) Low, at the same time, the synergistic relationship of most strains is general, and the simple anaerobic fermentation method is adopted, the yeast is mainly responsible for the fermentation of the feed, and the fermentation effect of other strains is very small
