Process for preparing deeply-cured compound feed for sucking pigs

Abstract

The invention discloses a process for preparing a deeply-cured compound feed for sucking pigs. The process is characterized by comprising the following steps of: crushing, curing and cooling corn, secondarily crushing the corn, mixing the crushed corn, proportioning and granulating, wherein the crushed corn is cured in a curing bin of a bulking machine, the curing degree is 45-60%, and the water content the corn after the corn is cured is 19-20%. The process has the beneficial effects that the corn is independently and deeply cured after being crushed, so that the curing degree and the gelatinization degree are increased, meanwhile, no nutrition loss is ensured, the palatability of the sucking pigs is improved, the chewing time is shortened, the chewing difficulty is lowered, the feed is convenient to eat by the sucking pigs, and the digestive absorption ratio and utilization ratio of the corn are increased; and the corn is mixed with other raw materials after being deeply cured and is then granulated at low temperature to ensure that nutrimental ingredients in other raw materials are prevented from being damaged by high-temperature water steam at an air inlet of the bulking machine, so that the nutrimental ingredients of the feed are reserved well, furthermore, the diarrhea rate of the sucking pigs is greatly reduced, and the large-dosage application of antibiotics and the dependence on the antibiotics are reduced.

Description

technical field [0001] The invention relates to a process for preparing suckling pig feed, in particular to a process for preparing deeply matured suckling pig compound feed, and belongs to the technical field of feed processing. Background technique [0002] In the field of feed processing, the feed currently on the market is generally simply mixed with various raw materials, and some products with the concept of ripening only use water vapor to denature part of the starch at a relatively low temperature of 65-85°C to achieve a simple effect. Adhesive effect of starch, little gelatinization of starch, it can be said that it only changes the appearance and shape of the feed, and does not achieve the actual effect of ripening. Therefore, the digestion and absorption utilization rate of this type of feed is low, and the diarrhea rate of suckling pigs High, increasing the difficulty of breeding. [0003] At the same time, in the existing curing process, the raw materials are o...

[0002] In the field of feed processing, the feed currently on the market is generally simply mixed with various raw materials, and some products with the concept of ripening only use water vapor to denature part of the starch at a relatively low temperature of 65-85°C to achieve a simple effect. Adhesive effect of starch, little gelatinization of starch, it can be said that it only changes the appearance and shape of the feed, and does not achieve the actual effect of ripening. Therefore, the digestion and absorption utilization rate of this type of feed is low, and the diarrhea rate of suckling pigs High, increasing the difficulty of farming

[0003] At the same time, in the existing curing process, the raw materials are often mixed quantitatively before curing and granulating. Since the temperature of the water vapor at the air inlet is often high, the products near the air inlet are often affected by temperature. If it is too high, some of the nutrients, especially vitamins with poor tolerance to high temperature, will decompose, denature and inactivate at high temperature, eventually resulting in the loss of nutrients in the feed
