[0039] Preparation of yeast activation solution

[0040] 1. Raw materials and equipment

[0041] Bread yeast powder 20g (Angel yeast powder for fermented bread, food grade, content ≥ 5 billion cfu / g);

[0042] 200 grams of brown sugar (food grade);

[0043] 1 stainless steel heating pot (capacity not less than 5 liters);

[0044] 2 liters of water;

[0045] 1 stirring stick (stainless steel or wood).

[0046] 2. The specific process is as follows:

[0047] Add 2 liters of water to a stainless steel heating pot, heat it to about 90 °C, add 200 grams of brown sugar, stir until completely dissolved, then stop heating, continue stirring to below 40 °C, add 20 grams of baker's yeast powder, continue to stir for 5 minutes; leave for 20 minutes It can then be used to inoculate fermented feed.

[0048] The number of viable yeast in the above yeast activation solution is 5×10 10 cfu / kg; its effective time is 2h; if it is not used temporarily, it can be stored in a 4 ℃ refrigerat...

Embodiment 2

[0103] The embodiment of the present invention provides a preparation method of antibiotic-free piglet feed.

[0104] 1. Raw materials and equipment

[0105] The raw materials and equipment used are the same as those in Example 1.

[0106] 2. Preparation method

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

[0108] After the soybean meal and wheat bran are mixed, pulverized, passed through a 20-mesh sieve, and added to the moist heat curing tank, and direct steam is introduced to heat the cooked material.

[0109] Start stirring at the beginning of feeding, and then slowly introduce heating steam to slowly increase the temperature of the material. 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; after the total flow of steam reaches 900kg (about 28min), stop the steam heating; continue stirring for 50 minutes, the material is transferred to...

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...
