A kind of preparation method of antibiotic-free piglet feed

Abstract

The invention discloses a method for preparing an antibiotic-free feed for piglets, which comprises the steps of: cooling a mixture of soybean meal and wheat bran after moist-heating, adding glucose, inoculating yeast and lactic acid bacteria, anaerobic fermentation to obtain moist-heating fermented material, and mixing with The whey powder, the premix and the dry-heat-cured corn material are evenly mixed; wherein, the starch gelatinization degree of the dry-heat-cured corn material is greater than 90%, and the content of globulin and Beta-conglycinin in the wet-heat-cured fermentation material All are less than 10mg / g. The present invention pre-digests bulk raw materials by adopting wet heat curing-anaerobic fermentation and dry heat curing, eliminates antigenic activity in protein raw materials, and improves the ripening degree of starch raw materials; the operation is simple, the equipment investment is low, and the popularization is easy; the prepared feed protein The content is between 16-17wt% and the water content is about 12%, which is easy to be digested by piglets, is conducive to the normal development of intestinal microorganisms, can reduce the weaning stress of piglets, and has good promotion value.

Description

technical field

[0001] The invention relates to the field of feed products, in particular to a preparation method of an antibiotic-free piglet feed. Background technique

[0002] With the rapid development of social economy and the continuous improvement of people's living standards, the food structure of residents has undergone significant changes, and the consumption of meat, milk, eggs and other livestock products has continued to increase, and animal husbandry has developed rapidly. Following this, the research and development of supporting feeds has also continued to flourish. In addition, since pork is the most consumed meat source in China, and piglet breeding is a very important part of pig breeding, the research and development of piglet feeds is receiving more and more attention. attention, its rapid development.

[0003] Antibiotic-free feeding of live pigs is the general trend, and it is also an inevitable requirement of relevant policies and regulations. At pr...
