Problems solved by technology

[0003] Traditional bio-fermentation protein pig feeds are produced by extensive fermentation methods, usually on open cement floor fermentation beds. Because this fermentation method is open, it is easy to be polluted by miscellaneous bacteria, and microbial metabolism during the fermentation process A large amount of biological energy is generated, and the temperature and heat cannot be controlled in time, which will affect the normal growth of microorganisms; because the materials on the surface of the fermentation bed are exposed to the air, the surface moisture is easy to disperse, which also affects the growth of microorganisms; the materials at the bottom of the fermentation bed are due to In contact with the ground, the oxygen demand is seriously insufficient, and it is easy to accumulate moisture and the material rots, resulting in uneven fermentation of the upper, middle and bottom parts of the fermentation bed.
After the fermentation, most of them are dried at high temperature to dehydrate the raw materials quickly, and the raw materials have to stay in a high temperature environment for a period of time to dry evenly, so that the volatile sour substances, aroma substances and vitamins in the fermented protein pig feed The loss of heat-sensitive substances such as probiotics and probiotics is serious, which reduces the nutrient content of the product to a certain extent, and cannot preserve the feeding value of bio-fermented protein pig feed to the maximum extent.

Embodiment

[0021] Embodiment A kind of preparation method of novel hepatoprotective microbial fermented protein pig feed, comprises the following steps:

[0022] (1) Prepare 100kg of probiotic strains;

[0023] (2) Weigh sucrose or glucose glucose 3.5, peptone 1.5, beef extract 1.0, sodium chloride 0.8, ammonium sulfate 0.6, potassium dihydrogen phosphate 0.075, yeast extract 0.5, magnesium sulfate 0.04 by weight (kg), add distilled water 100mL, Adjust the pH to 7.1, sterilize at 121°C for 40 minutes, prepare a seed liquid medium, and inoculate probiotic strains for cultivation;

[0024] (3) Expand the seed solution cultivated for 2 days for 1 day;

[0025] (4) Mix the expanded cultured bacteria liquid, 250kg of inland cottonseed meal, 150kg of DDGS, 80kg of soybean hulls, 25kg of molasses and tap water, and transfer them to a solid-state fermentation tank for solid-state fermentation;

[0026] (5) After the fermentation is over, the fermented microbial fermented protein pig feed wet m...

Abstract

The invention provides a novel liver-protection microorganism fermentation protein pig feed and a preparation method thereof. The method comprises the following steps: combining a fermentation tank technology with a low-temperature drying technology, fermenting raw materials such as cottonseed meal produced in the inland, DDGS, soybean hulls, probiotic bacteria liquid and molasses by using a solid-state fermentation technology, and controlling the temperature and material moisture in the fermentation process; after fermentation is finished, introducing low-temperature hot air to dry the materials. The liver-protection microorganism fermentation protein pig feed prepared by the method contains a lot of amino acids, activity probiotics and thermosensitive nutritive materials and is easily absorbed by animals, the digestive utilization ratio of the microorganism fermentation protein pig feed is increased, the activity of glutamic-pyruvic transaminase and glutamic oxalacetic transaminase in blood of piglets is reduced, and the liver function is protected, so that the growth of animals is promoted.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a novel liver-protecting microbial fermented protein pig feed and a preparation method thereof. Background technique [0002] Feed is a feedable substance that can provide the nutrients needed for raising animals, ensure health, promote growth and production, and have no harmful effects under reasonable use. Feed sources are relatively extensive, generally including soybeans, soybean meal, corn, wheat, cotton meal, rapeseed meal and other feed materials. The present invention uses inland cottonseed meal, DDGS, soybean hulls, and molasses raw materials to decompose toxic, harmful and anti-nutritional components in the raw materials after microbial fermentation, preserve the original nutritional components of the raw materials, and produce a large amount of nutrients through microbial metabolism. Metabolites and probiotics improve the quality of feed ingredients. [0003] Tradition...
