Preparation method of wet fermented granulated feed with high degree of cure used for suckling pigs and piglets

Abstract

The invention discloses a preparation method of a wet fermented granulated feed with high degree of cure used for suckling pigs and piglets. The preparation method of the wet fermented granulated feedwith high degree of cure used for suckling pigs and piglets is characterized in that the raw materials include a wet fermentation raw-material; and the wet fermentation raw-material is prepared by the steps of mixing a plant protein raw-material with water, inoculating the mixture with microbial strain, and carrying out fermentation. The preparation method of the wet fermented granulated feed with high degree of cure used for suckling pigs and piglets comprises the following steps: 1) preparing a wet fermentation raw-material; 2) performing steam condition treatment on a non-heat-sensitive raw material so as to obtain a raw material with high degree of cure; and 3) mixing the wet fermentation raw-material and the raw material with high degree of cure with other heat-sensitive raw materials so as to obtain a wet mixed powder material, carrying out extruding so as to obtain a wet granulated feed, and carrying out packaging by adopting a packing bag with an one-way vent valve. The preparation method of the wet fermented granulated feed with high degree of cure used for suckling pigs and piglets is capable of ensuring the degree of cure of the feed, reducing content of anti-nutritional factors in the feed, protecting biological activity of probiotics and metabolites thereof, and reducing hardness of the granules; and thus, the prepared wet fermented granulated feed with high degree of cure is capable of increasing feed intake and digestibility of suckling pigs and piglets as well as decreasing diarrhea rate.

Description

technical field [0001] The invention belongs to the technical field of feed processing technology, and relates to a method for processing granular feed for suckling piglets, in particular to a method for directly preparing wet granular feed with ripened raw materials and wet fermented raw materials. Background technique [0002] Improving the palatability, feed intake and digestibility of suckling piglet feed, and reducing the diarrhea rate have always been the goals pursued by the feed industry and the breeding industry. [0003] There are two main problems in the current production of suckling pig feed: [0004] First, the particle hardness is high [0005] Suckling piglets need feed with high nutrition, good food attraction, and soft pellets. However, the pellets currently produced generally have high particle hardness, and the suckling pigs are unwilling to eat. [0006] The second is dried fermented soybean meal, in which active substances such as probiotics have been...

AI Technical Summary

Problems solved by technology

However, active substances such as probiotics in dried fermented soybean meal have been inactivated, reducing its efficacy

[0008] Therefore, in view of the problems of high hardness and inactivation of the biological activity of fermented raw materials in the current pellet feed for suckling piglets, a new processing method for fermented pellet feed was developed, which not only protects the maturity of the feed and reduces the content of anti-nutritional factors in the feed The biological activity of the beneficial bacteria and their metabolites of the fermented raw materials can also reduce the hardness of the pellets, improve the nutritional value and palatability of the piglet feed, increase the feed intake and digestibility, and reduce the diarrhea rate, which is very necessary
