The sources of fermented feeds are very extensive. The use of a variety of microorganisms in the Kinpo feed starter can produce low-cost agricultural and light-duty byproducts such as dregs, pomace, corn syrup and sugar slag as high-quality feeds rich in probiotics and their metabolites. Or raw materials. Fermentation of different raw materials has different nutrition. According to the physiological characteristics of the used bacteria, the proportions of moisture, carbon-nitrogen ratio, calcium-phosphorus and growth-promoting factors need to be adjusted to facilitate the growth of microorganisms and the accumulation of target products. Let's take a closer look at its raw material characteristics and preparation.
1. Raw materials for fermented feed The types of raw materials for fermented feed are varied, and most of them are appendages or wastes for industrial and agricultural production activities. Wastewater such as alcohol, sugar, monosodium glutamate, paper, oil, etc.; industrial wastes rich in organic matter such as soy sauce, starch, molasses, methanol, and acetic acid; cassava, corn stalks, cowpea vines, peanut stalks, yam skin, orange peel, etc. Cellulose substances such as soybean meal, rice bran, sawdust, etc.; protein waste such as rapeseed, cottonseed cake, and sesame cake; and wool, blood, bones, hoofs, shells, and skins discarded by slaughterhouses; livestock manure in farms even include Urban life garbage. These raw materials have low prices, low utilization rates, improper handling, and even environmental pollution. The organic combination of production, waste comprehensive utilization and environmental protection through microbial fermentation of Golden Baby can not only make up for the shortage of feed ingredients in China, but also increase the utilization rate of raw materials. Environmental pollution. Cai Wei and other use of lactic acid bacteria, spores, yeast and other micro-ecological preparations of blood powder, leather powder, sesame meal, seed meal, horn powder, corn meal and other waste protein raw materials mixed solid state fermentation, the results of protein digestion rate from fermentation The former 75.9 % increased to 91.2 % after fermentation.
2. Preparation of raw materials
1) Water Any biological activity is indispensable for the participation of water, as is microbial fermentation. The moisture content of different fermentation feeds and the optimum fermentation water requirement are different. For example, the green feed silage with high water content should be dried for two hours or added with auxiliary materials before fermentation, while the raw materials such as chicken manure with low water content should be increased in water content. Normal water content can be fermented at 40-80%. The standard for judging the water content simply is: When the material is squeezed by hand, water will be printed out from the finger gap, but it does not drop out for the degree.
2) Equilibrium of Energy Protein (Combined with Fermentation) The contents of protein in mixed leeks, cottonseed meal, peanut cake, sesame cake and sunflower seed cake are relatively high, and the ratio of carbon to nitrogen is relatively small; while the coarse carbon and nitrogen of straw, weeds, etc. Higher, taking into account the energy and protein balance of microbial fermentation, that is, the ratio of carbon to nitrogen is generally 25:1, so if the ratio of carbon and nitrogen is not balanced before fermentation, all raw materials must be fermented with other raw materials.
3) Calcium, Phosphorus, Calcium and Phosphorus have an important role in promoting the fermentation of feed, not only improving the quality of fermentation, but also effectively promoting the absorption of nutrients from fermented feed. Because of the low content of calcium and phosphorus in root crops and potato stalks of potato crops, rice dumplings, and starch waste, calcium superphosphate (phosphorus fertilizer) or calcium hydrogen phosphate need to be added to promote fermentation, but for most of the raw materials, it is not fermented. Need to add calcium and phosphorus. Details can be consulted: Beijing Huaxia Kangyuan Technology Co., Ltd., toll-free hotline
