Problems solved by technology

[0002] At present, there are two most prominent problems in my country's feed industry: (1) Moldy feed
Especially in the humid south, the shelf life of the feed is only more than ten days, even if the commonly used antifungal agent calcium propionate is added, the effect is not ideal
(2) Abuse of antibiotics
Although the Ministry of Agriculture of China has banned the application of many kinds of powerful antibiotics in feed, once the disease-prone season comes, it is difficult to find more effective bacteriostatic agents than antibiotics on the market, even if feed manufacturers do not add them. The staff will still add antibiotics to the feed to ensure the survival rate of the animals

Embodiment 1

[0037] In this example, the weight ratio of monoglyceride laurate (70% monoester content), calcium propionate and feed carrier (maltodextrin) is 3:2:5.

[0038] (1) All raw materials are crushed to a particle size of 30 mesh, and then mixed uniformly according to the above ratio to obtain a feed additive;

[0039] (2) The feed additive was added to the feed raw materials of the piglet feed (see Table 2 for formula and nutrient composition) at an addition rate of 0.1%, and then extruded and granulated by a granulator to obtain a piglet feed.

Embodiment 2

[0049] In this example, the weight ratio of monoglyceride laurate (90% monoester content), calcium propionate and feed carrier (rice bran) is 3:3:4.

[0050] (1) All raw materials are crushed to a particle size of 30 mesh, and then mixed uniformly according to the above ratio to obtain a feed additive;

[0051] (2) The feed additive was added to the chicken feed (see Table 3 and Table 4 for formula and nutrient composition) at a dosage of 0.2%, and then extruded and granulated by a granulator to obtain the chicken feed.

Embodiment 3

[0064] In this example, the weight ratio of monoglyceride laurate (monoester content: 40%), calcium propionate and feed carrier (rice bran) is 7:3:10.

[0065] (1) All raw materials are crushed to a particle size of 20 mesh, and then mixed uniformly according to the above ratio to obtain a feed additive;

[0066] (2) The feed additive was added to the piglet feed (see Table 5 for the formula and nutrient composition) at a dosage of 0.3%, and then extruded and granulated by a granulator to obtain the piglet feed.

Abstract

The invention discloses a feed additive and an application of the feed additive. The feed additive comprises the following ingredients in percentage by weight: 20 to 60 percent of monoglyceride laurate, 10 to 40 percent of calcium propionate and 0 to 50 percent of feed carriers. The feed additive disclosed by the invention is added into feed raw materials, the feed is prepared in a stirring mixing or extruding granulation mode, the growth propagation of mycetes can be effectively inhabited, the storage period of the feed in the damp and hot season is prolonged, and in addition, the effects of inhabiting the bacteria, resisting viruses, reducing the use of antibiotics in the feed, promoting the animal growth and improving the animal survival rate and the disease resistance capability are realized; and meanwhile, the feed additive has the advantages that the cost is low, the process is simple, the operation is convenient, the safety is high, and the feed additive is suitable for practical production.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a feed additive and its application. Background technique [0002] At present, there are two most prominent problems in my country's feed industry: (1) moldy feed. Especially in the humid south, the shelf life of the feed is only more than ten days. Even if the commonly used antifungal agent calcium propionate is added, the effect is not ideal. (2) Abuse of antibiotics. Although the addition of antibiotics to feed can improve the survival rate of young animals and promote the growth of reared animals, it will cause food safety problems such as drug resistance. Although the Ministry of Agriculture of China has banned the application of many kinds of powerful antibiotics in feed, once the disease-prone season comes, it is difficult to find more effective bacteriostatic agents than antibiotics on the market, even if feed manufacturers do not add them. The staff will still add antibi...
