Compound feed for suckling pigs without animal proteins and preparation method thereof

Abstract

The invention relates to the technical field of special feed for young animals, in particular to a compound feed for suckling pigs without animal proteins and a preparation method thereof. The compound feed is prepared from, by weight, 50.3-70.5 parts of corn, 12-18 parts of soybean meal, 8-12 parts of expanded whole fat soybeans, 3-8 parts of fermented soybean meal, 1.5-2.0 parts of calcium hydrogen phosphate, 0.5-1.2 parts of stone powder, 1.2-2.0 parts of soybean oil, 0.3-0.5 part of sodium chloride, and 3-6 parts of a premixed feed, wherein in the fermented soybean meal, the content of small peptides is 20 wt% or above, the content of beta-conglycinin is less than 12mg / g, the content of soybean globulin is less than 20mg / g, the content of stachyose is less than <0.5 wt%, and the content of raffinose is less than 0.5 wt%. By replacing the fish powder in the original formula with the fermented soybean meal, the dependence of the compound feed for the suckling pigs on animal raw materials is reduced under the condition of maintaining the animal growth performance of the original feed, and therefore, long-term stable formulation cost and product quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of special feed for young animals, and more specifically relates to a compound feed for suckling pigs without animal protein and a preparation method thereof. Background technique [0002] As a young animal, suckling pigs need to use some special feeds to meet the needs of healthy growth. As we all know, the protein feed raw materials used in my country's feed industry mainly include plant protein raw materials and animal protein raw materials. The main raw materials are fish meal, beef bone meal, pork bone meal, porcine intestinal membrane protein powder, spray-dried porcine plasma protein powder, spray-dried porcine blood globulin powder and chicken powder. [0003] For pig production, due to the successive outbreaks of epidemic diarrhea and epidemic African swine fever in recent years, homologous animal protein raw materials have been clearly excluded in pig feed production, especially since the outbreak ...

AI Technical Summary

Problems solved by technology

Due to the shortage of fishmeal and chicken meal production resources in our country, they are mainly imported. As one of the main sources of imported fishmeal in my country, Peru has been affected by the El Niño climate for the past ten years. The fishing resources are unstable and the supply is often tense. In addition, these two raw materials are not only used in the production of livestock and poultry feed, but also the main raw materials for the production of aquatic feed. During the peak season of aquatic feed processing from March to November every year, the supply quantity and quality are difficult to meet the needs of the animal husbandry industry. The price is often 20-30% higher than usual, and fishmeal adulteration occurs from time to time
