Semi-wet livestock and poultry fine ecological feed additive agent and preparation method thereof

Abstract

The invention discloses semi-humid poultry micro-ecological feed additives and a preparation method thereof. The materials by weight portion of the preparation are: 15 to 25 portions of corn, 20 to 30 portions of bacteria liquid and 45 to 65 portions of carriers. The method comprises the following steps that: A. the corn, the bacteria liquid and the carriers are weighed and taken according to the weight portion at first, and the corn and the carriers are placed into a crusher for crushing and then mixed to prepare powdery mixed materials with a granularity which is less than or equal to 40 meshes; B. the bacteria liquid is then uniformly sprinkled into the powdery mixed materials; C. the powdery mixed materials with the bacteria liquid are placed into a fermenter for fermentation, a fermentation time is between 7 and 10 days, a fermentation temperature is between 18 and 28 DEG C, a humidity is between 25 and 35 percent and a PH value is between 3.8 and 5.0; and D. the fermented materials are sieved and undergo vacuum package of finished products. When used, the fermented mixed materials are uniformly mixed with feed according to the weight ratio of 1.5-2 percent and then can be fed. The additives have the functions of improving the immunity, increasing the yield and improving the stomach and intestine environment.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive of probiotics for livestock and poultry and a preparation method thereof. Background technique [0002] In recent years, No. 5 disease, bird flu, unknown high fever, infectious gastroenteritis, high copper, high zinc, and high doses of antibiotics in animal husbandry have brought obstacles to the development of the aquaculture industry, which has sounded a blow to the domestic aquaculture industry and feed enterprises. It raised the alarm bell, but also raised challenges and reflections. [0003] Since the discovery of the growth-promoting effect of antibiotics on animals in the middle of the 20th century, antibiotic additives have been widely used and made great contributions to the development of animal husbandry. Antibiotics are more effective than any other feed additive in improving animal performance. However, a large number of long-term use of antibiotics in feed has ca...

Problems solved by technology

However, a large number of long-term use of antibiotics in feed has caused other worrying problems. First, it has caused more and more serious drug resistance and drug resistance to livestock and poultry, making many commonly used antibiotics lose their antibacterial and therapeutic effects, and even causing livestock and poultry Body flora imbalance, growth retardation, etc.

What's more serious is that the human body increases drug resistance and drug resistance through the food chain and environmental pollution, which affects human health and safety.

[0004] Most of the probiotic products currently on the market are stone powder and zeolite powder as carriers, and the water content is about 8%. Not intuitive, difficult to reflect its application value
