Description

Suckling pig compound feed and processing method thereof

Technical Field

The invention relates to the technical field of feed processing technology, in particular to a suckling pig compound feed and a processing method thereof.

Background

The pigs with the weight less than 15 kg at the stage are called suckling pigs in China, and the feed used at the stage is called suckling pig feed. In the process of changing the process of eating the milk into the process of eating and processing the feed, the digestive enzyme system of the plant materials digested by the suckling pigs is underdeveloped, the capability of digesting the plant feed is poorer, in addition, the digestive tract of the suckling pigs has great allergic reaction to the main plant protein material bean pulp, and the diarrhea and malnutrition caused by allergy and dyspepsia have great influence on the growth, health and survival rate of the suckling pigs. The aim of controlling diarrhea is achieved by adding a large amount of antibiotics into the feed in the past, and the antibiotics are prohibited from being added into the feed in countries from 7/1/2020, so that the problems of slow growth and increased morbidity caused by diarrhea are fully exposed; the improvement of the digestibility of the suckling pig feed and the inactivation of the allergic factors in the soybean meal by changing the processing technology are fundamental ways for solving the problems.

The conventional compound feed for the suckling pigs is powdery, granular or powdery and granular, wherein part or all of the raw materials are subjected to expansion or dry-method expansion treatment to improve the digestibility and inactivate the allergic atoms in the soybean meal, but the method is not thorough in inactivation of the allergic factors in the soybean meal, in addition, the starch raw materials subjected to the dry-method expansion treatment are easy to be burnt in mouth, so that the feed intake of the suckling pigs is reduced, the feed waste is large, and the granular feed prepared from the expanded or expanded raw materials is high in hardness and is not suitable for being taken by early weaned suckling pigs. The dry-method puffing method cannot well improve the digestibility of the feed and inactivate the soybean meal allergic factors, simultaneously satisfies the fondness of the suckling pigs to the feed form, limits the nutrient intake of the early weaning suckling pigs, and easily causes the problems of insufficient nutrient intake, growth retardation, decline of health condition, increase of morbidity and the like.

Disclosure of Invention

The invention aims to provide a suckling pig compound feed and a processing method thereof, and the method can completely inactivate the activity of allergic factors in soybean meal raw materials in the suckling pig feed, improve the starch gelatinization degree, and greatly increase the feed intake, growth speed and breeding rate of the suckling pigs after weaning. We have studied to solve the following problems: the method of the invention adds 6% of grease in the production of the suckling pig compound feed, which can solve the problem of swelling and adhesion of starch raw materials in production; 2, the fat is firstly emulsified to solve the problem of fatty diarrhea of the suckling pigs caused by excessive fat addition. 3 the puffed suckling pig compound feed is crushed into small particles with the outer diameter of 1-4 mm by a double-roller crusher, so that the suckling pig compound feed is beneficial to feeding and uniform mixing with other small materials.

The technical scheme of the invention is as follows:

the invention relates to a suckling pig compound feed which is prepared by mixing the following raw materials in percentage by mass

60-70% of corn or rice or flour raw materials or raw materials mixed by more than two raw materials; 5 percent of super steam fish meal; 20-30% of a soybean meal vegetable protein raw material; 5-8% of emulsified oil.

The invention relates to a processing method of a suckling pig compound feed, which comprises the following steps:

step 1: formula setting and raw material weighing: setting specific raw material proportions according to the feed formula, and weighing corresponding raw materials according to the set feed proportions;

step 2: and (3) crushing the weighed starch raw materials, super steam fish meal and vegetable protein raw materials by using a crusher.

And step 3: adding emulsified oil and fat into the crushed raw materials in proportion, and uniformly mixing by a double-shaft blade mixer;

and 4, step 4: adding water and high-temperature saturated steam into the mixed raw materials in a conditioner for conditioning, feeding the raw materials into a double-screw bulking machine for bulking at the temperature of between 110 and 140 ℃, and cutting and forming after demolding; the starch-based wet-process puffing starch material can greatly inactivate allergic factors of beans under the condition of damp heat and improve the digestibility of starch, the wet-process puffing starch material has the problems of high viscosity and difficult separation, and the viscosity problem can be solved by adding emulsified oil into the material;

and 5: drying the puffed molding material by a dryer;

step 6: crushing the dried molding material by a double-roll crusher to form porous small particles with the outer diameter of 1-4 mm;

and 7: adding small materials and the crushed materials and uniformly mixing.

The invention has the beneficial effects that:

the method adds new steps of wet puffing, drying and crushing in the processing technology of the suckling pig compound feed, thereby renovating the processing technology of the existing suckling pig compound feed, breaking through industry understanding, breaking through the conventional process thought, having prominent effect and providing a new way for suckling pig breeding.

The method has the advantages that the method can greatly inactivate the allergic factors of beans under the damp and hot condition and can improve the digestibility of the suckling pigs to starch by adding water into the raw materials and adding high-temperature saturated steam for modulation and then carrying out puffing treatment; after drying and crushing, the small granules are crisp and cool and do not stick to the mouth, which is very beneficial to improving the feed intake of the suckling pigs; particularly, as the starch raw materials account for 60-70 percent of the compound feed for the suckling pigs, the high proportion of the starch raw materials has high viscosity after being expanded and can not be effectively separated, the wet method expansion treatment of the compound feed for the suckling pigs is not used in the market in the industry at present, even if the expansion treatment is adopted, a method of mixing part of the raw materials by expansion or dry method expansion treatment and then crushing the part of the raw materials into fine powder is adopted, and the feed intake of the suckling pigs is reduced because the starch raw materials after being expanded are crushed into the powder feed and easily paste the mouth. The emulsified oil is added into the feed, so that the problem of fat diarrhea of the suckling pigs caused by adhesion and excessive oil addition in the process of producing the suckling pig compound feed by a wet puffing method is well solved. And the activity of the allergic factors in the bean pulp raw materials in the suckling pig feed is more thorough by heating and inactivating by a wet method, the starch gelatinization degree and the digestibility of the suckling pig feed are greatly improved, the prepared broken small granules are crisp and comfortable, the feed intake, the growth speed and the breeding rate of the suckling pigs after weaning can be greatly increased, and the method is a fundamental way for solving the problem of nonreactive breeding of the suckling pigs.

The product of the invention is highly popular with customers after being put into production, the feedback is extremely good, the sales volume rapidly increases in a short time, and the sales volume of the product in 5 months is increased by 500 percent; sales at 6 months are expected to increase ring ratio by 110%; the advantages and advantages of the product are greatly superior to those of other existing suckling pig compound feed products in actual use effect.

The social significance of the invention is as follows:

the invention can well solve the problem of diarrhea commonly encountered by the suckling pigs after the resistance inhibition of the feed, and the diarrhea rate of the suckling pigs after weaning is reduced from 10-60 percent to less than 2 percent under the condition of no antibiotic

2, the feed intake of the weaned piglets is greatly improved by 50-100 percent according to market inspection
