Problems solved by technology

[0004] The purpose of the present invention is to provide a fermented antibiotic-free protein source material and its preparation method and application, aiming to solve the problem that soybean meal as a protein feed raw material affects the intestinal health and digestion and absorption of animals due to toxins such as tannins and anti-nutritional factors. At the same time, the antibacterial function of fly maggots is used to improve the immunity of animals, but the cost of breeding fly maggots in traditional techniques is too high and the process is complicated.

preparation example Construction

[0020] The embodiment of the present invention provides a method for preparing a fermented antibiotic-free protein source material. The fermented antibiotic-free protein source material is fermented by mixing fly maggots and soybean meal. The preparation method includes the following steps:

[0021] S01. Collect blood from slaughtered animals, add corn flour, bran, and yeast to mix evenly, seal and ferment for 12-24 hours, and use it as food for fly maggot larvae;

[0022] S02. Add 80-120 grams of fly maggot larvae to every 100 kilograms of the fly maggot larvae food. After 3-4 days of cultivation, the young maggots grow up and mature, and add soybean meal to continue the cultivation, wherein, the fly maggot larvae food and the soybean meal The mass ratio is 1:1 (0.8-1.2);

[0023] S03. When the water content in the fly maggot culture is 30-35%, add allicin and sodium diacetate, mix evenly, pack into a bag and seal it for storage to obtain a fermented non-antibiotic protein so...

Embodiment 1

[0047] A method for preparing a fermented antibiotic-free protein source material, comprising the steps of:

[0048] S11. Collect 75 kg of animal slaughtered blood, add 5 kg of corn flour, 20 kg of bran, and 100 g of saccharomyces, mix evenly, seal and ferment for 24 hours, and use it as food for fly maggot larvae;

[0049] S12. Provide 250 grams of fly maggot larvae, put them into the food of the fly maggot larvae, and cultivate them under the condition of 25-30°C for 72 hours, and then the fly maggots grow up. Add 100 kilograms of soybean meal and spread on the surface of the fly maggot culture, continue to cultivate;

[0050] S13. After 24 hours, when the water content in the fly maggot culture is 30-35%, add 100 grams of allicin and 300 grams of sodium diacetate, mix evenly, pack into bags and seal to obtain fermented protein-free material.

Embodiment 2

[0052] A grass carp feed, based on the mass of the grass carp feed as 100%, comprises the following components in the following mass percentages, wherein the fermented antibiotic-free protein source material is the fermented antibiotic-free protein prepared by the method described in Example 1 source material,

[0053]

[0054] After the materials are pulverized and mixed evenly, a pellet machine is used to make grass carp pellet feed.

Abstract

The invention provides a preparation method of an antibiotic-free fermented protein source material. The antibiotic-free fermented protein source material is prepared from fly maggot and soybean meal by mixing and fermenting. The preparation method comprises the following steps: animal slaughtered blood is collected and uniformly mixed with corn flour, bran and yeast, the mixture is fermented in a closed manner for 12-24 h, and a fermentation product is taken as food of fly maggot larvae; 80-120 g of fly maggot larvae are added to every 100 kg of the food of the fly maggot larvae, the maggot larvae grow and mature after being cultured for 3-4 d, and the soybean meal is added for continuous culture, wherein the mass ratio of the food of the fly maggot larvae to the soybean meal is 1:(0.8-1.2); when the water content of the fly maggot culture is 30%-35%, allicin and sodium diacetate are added, the materials are uniformly mixed, bagged, sealed and stored, and the antibiotic-free fermented protein source material is obtained. Allicin accounting for 0.6-1.0 permillage by mass of the soybean meal is added, and sodium diacetate accounting for 1.3-1.6 permillage by mass of the soybean meal is added.

Description

technical field [0001] The invention belongs to the technical field of protein feed, and in particular relates to a fermented antibiotic-free protein source material and its preparation method and application. Background technique [0002] More and more antibiotics need to be used in the feed manufacturing process and animal breeding process. Excessive use of antibiotics will lead to the final transfer of residual antibiotics to the human body, causing huge negative effects. With the passage of time, the harm of adding antibiotics in feed has become increasingly apparent, and has received widespread attention from the society. In 2004, WTO, the Food and Agriculture Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE) jointly held a symposium to discuss the use of non-human antibiotics and antibiotic resistance. Since January 2006, the European Union has banned the addition of antibiotics in livestock and poultry feed. It is currently ...
