Method for producing concentrated feed for porkets

Abstract

The invention discloses a method for producing a concentrated feed for porkets. The concentrated feed for porkets is formed by adding a protein material and an additive into a carrier, wherein the protein material comprises bean dregs, cotton dregs and fish meal. The method for producing the concentrated feed comprises the following steps: firstly, preprocessing the protein material to obtain a semi-finished product of the protein material and then mixing the semi-finished product of the protein material, the additive and the carrier according to the mixture ratio of each component of the concentrated feed for porkets to obtain a feed; then, pulverizing the bean dregs, the cotton dregs and the fish meal of the protein material respectively, sieving, mixing fully after metering and weighing according to the mixture ratio, granulating by a feed granulator, curing a particle protein material by a curing device, cooling the cured particle protein material, pulverizing, sieving, obtaining the semi-finished product of the protein material and finally, mixing the semi-finished product of the protein material, the additive and the carrier according to the mixture ratio of the feed to obtain the concentrated feed for porkets. The production method preprocesses the protein material, enhances the stability of the feed, optimizes the quality of the feed, strengthens the digestion and the absorption of nutrition and the utilization rate of the feed and promotes the healthy growth of the porkets.

Description

technical field [0001] The invention relates to a feed production method in pig breeding industry, in particular to a production method of concentrated feed used in suckling pig breeding. Background technique [0002] my country is a big traditional pig breeding country in the world, but the production method of pig feed in our country, especially the concentrated feed for suckling pigs, still adopts the traditional production method of concentrated feed for medium and large pigs, that is, the protein raw materials soybean meal, cotton meal and fish meal in the formula are coarsely powdered, and mixed with The additives are mixed and fed directly. [0003] The digestive system of piglets should be 6-8 weeks old, and the immune system should be 4-7 weeks old to gradually improve and mature. In order to achieve the purpose of improving the whole growth level of pigs, it is necessary to realize early weaning and early feeding. At present, the components of concentrated feed fo...

Problems solved by technology

At present, the components of concentrated feed for suckling pigs include protein raw materials, vitamins and other additives and carriers. The protein raw materials are mainly soybean meal, cotton meal and fish meal; Contains protease inhibitors, which can reduce the feed intake, daily gain and feed conversion rate of suckling pigs, affect digestion and absorption, thereby affecting the gastrointestinal tract function of suckling pigs, causing diarrhea, slow weight gain and even death; cotton meal is a protein The raw material is a relatively cheap protein source, but cottonseed meal contains gossypol and other toxic substances, which can cause vomiting and poisoning to suckling pigs; fish meal is currently the best protein source for the growth and development of suckling pigs, but due to processing and storage, etc. , even fresh imported fishmeal will produce bacterial toxins such as E. ), harmful substances (gossypol) and pathogenic microorganisms (Escherichia coli, Salmonella, etc.) Intestinal digestion and immune function decline, physiological development and growth performance are inhibited, eventually causing diarrhea, death and growth stagnation in suckling pigs
