Method for preparing predigested feed

Abstract

The invention discloses a method for preparing a predigested feed, which comprises the following steps of: inspecting and crushing grains, mixing the materials, making a slurry, preheating the slurry, adjusting the pH value for the first time, adding a complex enzyme No.1, hydrolyzing, adjusting the pH value for the second time, adding a complex enzyme No.2, neutralizing the slurry, passivating the enzymes, performing drum drying, removing impurities, and crushing the materials until the finished product is obtained. In the invention, the digestion process in animal bodies is simulated, the nutrient substances and the chemical structure of the predigested feed are changed, the proteins are decomposed into small peptides and amino acids, the saccharides are decomposed into polysaccharides, disaccharides and monosaccharides, and the decomposition products are easier to be absorbed and utilized by animals. When the predigested feed is used as a high-quality feed raw material for weaned piglets, the resources can be saved, the incidence rate of diarrhea for the weaned piglets is reduced, the weight of weaning litter is increased, and the production efficiency of pig husbandry is improved. The use of the predigested feed can reduce the use of antibiotics in the pig husbandry link and is an effective means to realize green and safe husbandry.

Description

technical field [0001] The invention relates to a preparation method of predigested feed. Background technique [0002] The existing feed processing methods mainly focus on the rough processing and compounding of raw materials. Generally, several physical processing processes such as formula optimization, raw material crushing, mixing, and granulation are required. Sexual changes. [0003] With the continuous improvement of feeding technology, the weaning age of piglets is advanced, and early weaning and even super early weaning have appeared, but this also poses a challenge for how to prepare feed that is easy to be absorbed and utilized by piglets. At this physiological stage, the gastrointestinal mucosa of early weaned piglets and the corresponding enzyme system are not fully developed, and it is difficult for piglets to fully absorb and utilize general feed, especially for the main raw material in existing suckling piglet feed - plant There are big problems in the dige...

[0003] With the continuous improvement of feeding technology, the weaning age of piglets is advanced, and early weaning and even super early weaning have appeared, but this also poses a challenge for how to prepare feed that is easy to be absorbed and utilized by piglets

At this physiological stage, the gastrointestinal mucosa of early weaned piglets and the corresponding enzyme system are not fully developed, and it is difficult for piglets to fully absorb and utilize general feed, especially for the main raw material in existing suckling piglet feed - plant There are big problems in digestion and absorption of sexual raw materials, and the antigenicity of these raw materials and certain anti-nutritional factors can aggravate the incidence of diarrhea in piglets
