With the advent of winter, dust has become the most prominent problem affecting the health of poultry. Among the diseases that have occurred, more than 40% of the diseases are transmitted through the air, and in the sudden severe diseases, more than 70% are related to ambient air quality.
If the environment is not properly controlled, a large amount of dust, toxic and harmful gases and harmful microorganisms will be produced in the chicken house. The toxic and harmful gases will directly stimulate the respiratory epithelial mucosa, causing edema, inflammation and other diseases. The harmful microorganisms adsorbed by the dust will take the opportunity to invade, multiply and spread to the whole body through the blood circulation, thus causing the chickens to become ill.
Causes of dust generation
The dust in the chicken house mainly comes from bedding, feed, feces, chicken skin, feathers, droplets produced by coughing and chirping, microorganisms and fungi in the air. Under normal circumstances, the total dust concentration in the air of the chicken house is about 4.2 mg/m3The total suspended particulate matter concentration is 30 times the national standard limit value.
With the application of automation in the chicken industry, automatic feeding machine feeding has become the main source of dust in the chicken house.
Harm of Dust in Chicken House
1. The dust in the air of the chicken house will stimulate the respiratory tract and cause inflammation, and a large number of pathogenic microorganisms are attached to the dust. Therefore, the dust is the carrier of spreading diseases, and the dust inhaled from the respiratory tract can continuously send pathogenic microorganisms into the inflamed part.
Due to the large number of microorganisms attached to the dust in the chicken house, it can continuously decompose the organic matter in the dust to produce odor. The continuous effect of these harmful gases will cause damage to the respiratory system of the chicken and cause respiratory diseases.
2, high concentration of dust environment will directly lead to chicken due to dust airway obstruction and death, studies have shown that H5N1 virus can use dust to last for several weeks to several months of activity, and Marek virus can use dust to survive for 44 days.
