Problems solved by technology

At the same time, the high-yield carotenoids fermented by this bacteria is a major feature of it. So far, no bacteria that can decompose fiber, increase protein content and produce high-yield natural pigments have been found in the field of feed fermentation.

Embodiment 1

[0015] Mix 10-70% hulled bran, 30-90% rice bran / degreased rice bran, and 0.5-4% ammonium sulfate evenly, then moisten and steam the material, cool the clinker to 20-40°C, crush it quickly, and inoculate the thick veined cells Bacteria (0.5%, w / w) and Lactobacillus plantarum (1.0%, v / w) were cultured at 30°C for 4 days, and dried at 60°C after fermentation to obtain fermented probiotic feed. The crude fiber degradation rate in the finished feed is 40%, the protein growth rate is 34%, and the number of active Lactobacillus plantarum reaches 10% 11 cfu / g feed, the carotenoid content can reach 350-450mg / kg feed dry weight.

Embodiment 2

[0017] Mix 0-100% bean dregs, 0-100% rice bran / degreased rice bran and 0.5-3% ammonium sulfate evenly, then moisten and steam the clinker, cool the clinker to 20-40°C, crush it quickly, and inoculate it with Neuroma fortis (0.5%, w / w) and Lactobacillus plantarum (1.0%, v / w) were cultured at 32°C for 3 days, and dried at 55°C after fermentation to obtain fermented probiotic feed. The degradation rate of crude fiber in the finished feed is 45%, the growth rate of protein is 38%, and the number of active Lactobacillus plantarum reaches 10% 12 cfu / g feed, the carotenoid content can reach 380-500mg / kg feed dry weight.

Embodiment 3

[0019] Mix 10-75% crop straw powder (straw or wheat straw, etc.), 25-90% rice bran / degreased rice bran and 0.5-4% ammonium sulfate evenly, and then moisten and steam the clinker. Knead it, inoculate it with Neurostria clostrium (1.0%, w / w) and Lactobacillus plantarum (1.5%, v / w), culture it at 28°C for 5 days, and dry it at 60°C after fermentation to get the fermented probiotic feed. The degradation rate of crude fiber in the finished feed is 47%, the growth rate of protein is 40%, and the number of active Lactobacillus plantarum reaches 10% 11 cfu / g feed, the carotenoid content can reach 350-400mg / kg feed dry weight.

Abstract

A method for producing probiotic feed for animals by fermenting high-fiber agricultural and sideline products with complex bacteria. , and / or 0-1.0% calcium chloride and / or 0-1.0% magnesium sulfate) are mixed in proportion and then steamed with water; after the steaming is completed, cool to 20-40°C and inoculate Neurostria fortis and Lactobacillus plantarum is solid-state fermented at 20-40°C for 2-5 days; the fermented feed is dried at 40°C-70°C and crushed to obtain a probiotic feed product rich in carotenoids. The method has the advantages of high production efficiency, low cost and good benefit, and while solving the problem of environmental pollution, it also relieves the pressure of serious shortage of energy and protein feed sources.

Description

[0001] technical field [0002] The invention is an animal probiotic feed with high-fiber agricultural and sideline products as raw materials, which is fermented by complex bacteria to produce high protein and natural carotenoid content, low fiber content and rich nutrition, and belongs to the field of deep processing of agricultural and forestry by-products. Background technique [0003] High-fiber agricultural by-products are produced during the production and processing of agricultural products, such as rice bran, rice bran / defatted rice bran, crop straw, bean dregs, bran, brewer's grains, tea meal / cake, rapeseed meal / cake, stevia slag , Chinese medicine dregs, apple pomace and yam skin, etc. my country is a large agricultural country, and the output of high-fiber agricultural and sideline products is huge. Due to the limited technical level, these agricultural and sideline products have not been effectively utilized, and the utilization rate and economic benefits are low...
