Embodiment 1
[0026] A method for monitoring environmental microbial aerosols in a closed livestock and poultry house, comprising the following steps:
[0027] Step 1. Arrangement of sampling points: In the net bed pig house, the points are arranged according to the method of selecting points on the four equal diagonal lines, and at least 5 points are set at the sampling points; From the center of the house as the starting point, select equal sampling points from the starting point to the four corners of the net bed pig house, and use the equal sampling points and the central point of the livestock and poultry house to form 5 sampling points; figure 1 As shown, three-layer sampling is selected for sampling, and the heights are respectively 0.2m for the first layer 1, 0.4m for the second layer 2 and 0.6m for the third layer 3;
[0028] Step 2. Continuously sample the sampling points through the air microbial aerosol sampling device in the net-bed pig house, use metagenomic technology to anal...
Embodiment 2
[0030] A method for monitoring environmental microbial aerosols in a closed livestock and poultry house, comprising the following steps:
[0031]Step 1. Arrangement of sampling points: In the caged laying hen house, the points are arranged according to the method of quartering the diagonal line selection, and the sampling points are set at least 5 points; The center of the laying hen house is used as the starting point, and equal sampling points are selected from the starting point to the direction of the four corners of the caged laying hen house, and five sampling points are composed of equal sampling points and the center point of the caged laying hen house; three layers are selected for sampling Sampling, the heights are 0.8m, 1m and 1.2m respectively;
[0032] Step 2. Continuously sample the sampling points through the air microbial aerosol sampling device in the caged layer house, use the metagenomic technology to analyze the type and content of microorganisms, and combi...
Embodiment 3
[0034] A method for monitoring environmental microbial aerosols in a closed livestock and poultry house, comprising the following steps:
[0035] Step 1. Arrangement of sampling points: in the ground breeding duck house, the points are arranged according to the method of quadrangling the diagonal line selection, and at least 5 sampling points are set; Take the center of the house as the starting point, select equal sampling points from the starting point to the four corners of the ground breeding duck house, and use the equal sampling point and the center point of the ground breeding duck house to form 5 sampling points; select three-layer sampling for sampling, and the heights are respectively 0.1m, 0.3m and 0.4m;
[0036] Step 2. Continuously sample the sampling points through the air microbial aerosol sampling device in the duck house on the ground, use the metagenomic technology to analyze the type and content of microorganisms, and combine bioinformatics to obtain dominan...
