Embodiment 2

[0103] The embodiment of the present invention provides a method for preparing feed for piglets without antibiotics.

[0104] 1. Raw materials and equipment

[0105] Adopted raw material and equipment are with embodiment 1.

[0106] 2. Preparation method

[0107] S1. Moist heat aging and anaerobic fermentation of soybean meal and wheat bran

[0108] After mixing the soybean meal and wheat bran, crush them, pass through a 20-mesh sieve, add them into a humid-heat curing tank, feed in direct steam, and heat the materials for curing.

[0109] Start stirring at the beginning of feeding, and then slowly introduce heating steam to make the temperature of the material rise slowly. When it reaches 80°C, gradually increase the steam flow, but it is necessary to control the temperature of the material not to exceed 105°C; wait until the total flow of steam reaches 900kg (about 28min), stop steam heating; after continuing to stir for 50 minutes, the material is transferred to the mixe...

Abstract

The invention discloses a preparation method of an antibiotic-free piglet feed, which comprises the following steps: carrying out damp-heat curing on a mixture of soybean meal and wheat bran, cooling,adding glucose, inoculating saccharomycetes and lactic acid bacteria, carrying out anaerobic fermentation to obtain a damp-heat cured fermented material, and uniformly mixing the damp-heat cured fermented material with whey powder, a premix and a dry-heat cured corn material to obtain the antibiotic-free piglet feed. Wherein the starch gelatinization degree of the dry-heat cured corn material isgreater than 90%, and the contents of globulin and Beta-conglycinin in the damp-heat cured fermented material are both less than 10mg / g. According to the invention, a large amount of raw materials arepre-digested by adopting a damp-heat curing-anaerobic fermentation and dry-heat curing mode, so that the activity of antigens in the protein raw material is eliminated, and the curing degree of the starch raw material is improved; operation is simple, equipment investment is low, and popularization is easy; the protein content of the prepared feed is 16-17wt%, the water content is about 12%, andthe feed is easy to digest by piglets, is beneficial to normal development of intestinal microorganisms, can reduce weaning stress of the piglets, and has good popularization value.

Description

technical field [0001] The invention relates to the field of feed products, in particular to a method for preparing feed for piglets without antibiotics. 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 livestock products such as meat, milk, and eggs has continued to increase, and animal husbandry has developed rapidly. 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 farming, the research and development of piglet feed is receiving more and more attention. Attention is paid to its rapid development. [0003] The antibiotic-free feeding of pigs is the general trend and an inevitable requirement of relevant policies and regulations. At present, the ant...
