Embodiment 1

[0019] Embodiment 1, the preparation of micro-ecological feed additive of the present invention

[0020] The microecological feed additive refers to beneficial microorganisms and their metabolites that can promote the ecological balance of microorganisms in animals.

[0021] The specific preparation method of micro-ecological feed additive of the present invention is as follows: take 350 kilograms of Bacillus subtilis solids of clear liquid fermentation spray drying, 350 kilograms of Bacillus licheniformis of clear liquid fermentation spray drying, the butyric acid of clear liquid fermentation press filter drying Mix 50 kg of clostridium and 150 kg of SSF enzyme dried at 120°C for solid fermentation, then add 100 kg of 40-mesh corn bran powder, put it in a mixer at 200 rpm and mix for 10 minutes to obtain 1 ton of finished product. The carrier can also choose bran or rice husk powder. The above-mentioned Bacillus subtilis, Bacillus licheniformis, Clostridium butyricum, SSF en...

Embodiment 2

[0026] Embodiment 2, the influence of the micro-ecological feed additive of the present invention on the ammonia concentration of the poultry house

[0027] Select 8 chicken coops (coop size: 120m×14m / house, breeding capacity: 16,500 birds / house), and then divide them into two groups, the test group (1000g / T of this product is added to the basic diet) and the control group (basic diet) diet). Air sampling: 30cm from the ground; Sampling point: Take 3 calculated average values ​​at the front, middle, and back of the chicken house; Sampling time: 7:00 in the morning, unit: ppm.

[0028] Table 1 Effects of the microecological feed additives on ammonia concentration in poultry houses

[0029] age

[0030] It can be seen from Table 1 that from the age of 7 days to the age of 28 days, with the increase of the age of the chickens, the production of ammonia gas continued to increase. However, because the experimental group ate the diet containing micro-ecological feed addi...

Embodiment 3

[0031] Embodiment 3, the influence of micro-ecological feed additive of the present invention on ammonia concentration in piggery

[0032] Select 4 120-150-day-old fattening pig houses (pig house size: 45m×10m; breeding capacity: 50 heads×4 pens), and randomly divide them into two groups, the test group (add 1000g / T of this product to the basic diet) ) and the control group (basal diet). Air sampling: 60cm from the ground. Sampling points: Take 3 samples from the front, middle and back of the pig house to calculate the average value. Sampling time: 7:00 am, unit: ppm.

[0033] The impact of the micro-ecological feed additives described in Table 2 on the ammonia concentration in the piggery

[0034] age

[0035] It can be seen from Table 2 that before feeding, the ammonia concentrations in the pig houses of the test group and the control group were basically the same, and from 3 days to 15 days after feeding, compared with the control group, the ammonia concentrati...

Abstract

The invention provides a microcological feed additive for lowering the concentration of ammonia in a livestock and poultry house and application of the microcological feed additive. The microcological feed additive comprises the following components: bacillus subtilis in the ratio of 3.92-4.08*10<9>pcs / g, bacillus licheniformis in the ratio of 0.98-1.02*10<9>pcs / g, butyrate clostridium in the ratio of 1.96-2.04*10<8>pcs / g, SSF (sodium fluosilicate) enzyme prepared by aspergillus oryzae in the ratio of 148-152mg / g and a carrier in the ratio of 98-102mg / g. The microcological feed additive for lowering the concentration of ammonia in the livestock and poultry house can improve protein absorbing capacity of an intestinal canal of livestock and poultry through producing enzyme, thus a nitrogensource is reduced; growth of putrefying bacteria is inhibited by beneficial bacteria, thus emission of the ammonia is reduced; and the activity of urease is inhibited, and the ammonia generated by uric acid and urea under the catalysis of urease is reduced, thus the aim of lowering the concentration of the ammonia in a livestock house is achieved.

Description

technical field [0001] The invention belongs to the technical field of livestock feed and relates to a micro-ecological feed additive, in particular to a micro-ecological feed additive for reducing ammonia concentration in livestock and poultry houses and an application thereof. Background technique [0002] Raising livestock and poultry can provide people with daily necessities such as meat, eggs and milk, and has an extremely important social and economic role. Pollutant gases are often discharged into the environment outside the livestock and poultry houses, which is considered to be one of the largest sources of greenhouse gas emissions, thus causing great environmental pollution. content. [0003] At present, with the rapid development of animal husbandry, large-scale, closed and intensive breeding methods are increasing. Although this has greatly improved the production efficiency and economic benefits of animal husbandry, livestock and poultry breeding not only shar...
