Soft pellet feed and preparation thereof

Abstract

The invention belongs to the field of feed processing technology, and particularly relates to soft pellet feed and the preparation thereof. The preparation comprises the following steps: taking compositions including whey powder, milk powder, cane sugar, trehalose, soybean phospholipid powder and calcium formate as per the matched ratio, and dissolving the compositions in high fructose corn syrup, so as to produce composite syrup; taking materials including rice, corn, peeled soybean meal and fermented soybean meal as per the matched ratio, and smashing the materials preliminarily; performing ultramicro smashing on the materials in the last step and other raw materials until the particle size is 15 microns, mixing all the materials, and sending the materials into a soft pelleter to carry out pelletizing, wherein the pulverization ratio is less than or equal to 6%; uniformly spraying the composite syrup on the surface of the pellet materials by using a syrup spraying dripping device, wherein the pellet diameter is 1-3 mm; finally, packing into finished products in an automatic and quantitative manner. According to the soft pellet feed provided by the invention, the possibility of hardening of the pellet materials in the storage process can be reduced, the nutrient substance loss in the high-temperature pelletization process can be reduced, while good taste and excellent palatability are realized, and food consumption of piglets is increased.

Description

technical field [0001] The invention belongs to the field of feed processing technology, and in particular relates to a soft granular feed and its preparation. Background technique [0002] At present, the suckling pig pellets commonly used in the market generally add more sugar, whey powder, puffed corn or other digestible raw materials. Since the raw material contains a large amount of starch, if no corresponding measures are taken, the aging problem of starch will inevitably exist during the storage process, which will cause the product to become brittle and hard when stored for a long time, easy to disintegrate, and the taste will become poor, thus affecting The palatability of the product reduces the feed intake of suckling piglets. Fermenting the main raw materials in the feed is a frequently used means to solve this problem. In addition, during the processing of pellets, due to high-temperature heating and granulation, heat-sensitive nutrients will be lost, which wi...

AI Technical Summary

Problems solved by technology

However, the above-mentioned invention still generally adopts the method of drying after fermentation or partially drying and packaging, which does not fundamentally solve the problems that the product is not easy to form and the storage period becomes brittle and hard, and the problem of poor taste

In addition, during the processing of pellets, due to high-temperature heating and granulation, it is easy to cause the loss of heat-sensitive nutrients and reduce the value of feed, thereby affecting animal production performance.
