Problems solved by technology

At present, when livestock and poultry are raised in agriculture in my country, the monitoring of their breeding environment is still at a relatively primitive stage, mainly relying on physical and chemical methods to judge the comprehensive environment of livestock and poultry houses. Due to lack of funds, the accuracy of monitorin

Embodiment 1

[0033] A method for monitoring ambient air particles in a closed livestock and poultry house, comprising the following steps:

[0034] Step 1. Sampling point layout: such as figure 1 As shown in the schematic diagram of the sampling points in the top view of the net-bed pig house, the points in the net-bed pig house are arranged according to the method of quadrant diagonal line selection, at least 5 sampling points are set, and the sampling height is 0.6m from the ground of the livestock and poultry house; The four-diagonal point selection method refers to the center of the pig house as the starting point, the selection of equal sampling points from the starting point to the four corners of the livestock and poultry house, and the equal sampling point and the central point of the livestock and poultry house to form 5 Sampling point;

[0035]Step 2. Continuously sample the sampling points in the livestock and poultry house through the particle sampler to monitor the particle c...

Embodiment 2

[0037] A method for monitoring ambient air particles in a closed livestock and poultry house, comprising the following steps:

[0038] Step 1. Arrangement of sampling points: in the caged laying hen house, the points are arranged according to the quadrant diagonal line selection method, and the sampling points are set at least 5 points, and the sampling height is 1.6m from the ground of the livestock and poultry house; Diagonal point selection method refers to starting from the center of the pig house, selecting equally divided sampling points from the starting point to the four corners of the livestock and poultry house, and forming 5 sampling points with the equally divided sampling points and the center point of the livestock and poultry house;

[0039] Step 2. Continuously sample the sampling points in the livestock and poultry house through the particle sampler to monitor the particle concentration; the continuous sampling process includes feeding feed, peak feeding period...

Embodiment 3

[0041] A method for monitoring ambient air particles in a closed livestock and poultry house, comprising the following steps:

Abstract

The invention discloses a closed-type internal animal building ambient air particle monitoring method. The closed-type internal animal building ambient air particle monitoring method comprises the following steps: points are distributed in an animal housing by a quartered diagonal selected-point method, at least five points are provided as sampling points, and the sampling height is 0.4-1.5 m above the ground of the animal house; the sampling points are continually sampled in the animal house through a particle sampler, and the concentration of particles is monitored; and the continuous sample method comprises sampling during feed feeding, animal rest, cleaning of the animal house, and bedding change. As the particles in the animal house are continually monitored, the grain size distribution of air fine-particles in the animal house are acquired by the particle sampler, and impacts on chemical characteristics of the particles from such factors as animal management, animal ingestion and excretion are analyzed and studied; and by virtue of animal in-vivo test and in-vitro experiments models, impacts on physiological and biochemical indexes, behavioral indexes and production performance indexes of animals in different growth stages from the particles in the animal house are studied, and a theoretical basis is provided to guarantee and improve the animal health.

Description

technical field [0001] The invention relates to a particulate matter monitoring method, in particular to a monitoring method for ambient air particulate matter in a closed livestock and poultry house. Background technique [0002] my country is a large livestock and poultry breeding country, with a large number and variety of livestock and poultry. Their growth is affected by genetics, products, feed, diseases and the environment. A large number of scientific production and practical experience have confirmed that environmental impact factors account for 30%, and with the rapid development of intensive and large-scale farming, the proportion of environmental impact will become larger and larger. Especially in recent years, due to the large number of closed livestock and poultry houses, the environment in the house has become more and more complicated. The frequent outbreak and spread of livestock and poultry epidemic diseases such as foot-and-mouth disease, swine unknown hig...
