How is the Dairy Farm Environment?

Dairy farming is the guarantee of milk and dairy products supply in different regions. How to improve the output and quality of milk is a problem that farms pay more attention to. When dairy cattle are cultured on a large scale, the excrement produced will pollute the surrounding environment, and also lead to the breeding of bacteria and pathogens, and affect the growth of dairy cattle. Farms need to pay attention to the problem of pollution in dairy farm environment and take effective measures to control it, so as to protect the surrounding environment and provide protection for the high yield of dairy cows.

1. Causes of Environmental Pollution in Dairy Farm

The environmental pollution of dairy farming mainly includes four aspects: soil pollution, water pollution, air pollution and microbial pollution.

(1) Soil pollution: In dairy cow production, inorganic mineral elements are usually added in excess dosage. Because of its low utilization rate, a large part of inorganic mineral elements are not absorbed and discharged from the body. With fertilization, they enter the farmland and accumulate in the soil, which poses a threat to crop growth and human health.

(2) Water pollution: Nitrogen and phosphorus in feces and urine are the main sources of water pollution in dairy cow production. Nitrogen and phosphorus uptake and utilization rate of dairy cows is very low, only about 30%~35%. A large number of nitrogen and phosphorus which are not absorbed and utilized are discharged out of the body, most of which enter the soil, and enter surface water sources and underground water sources through the erosion of rainwater. Nitrogen in water mostly exists in the form of nitrate, and excessive nitrate in drinking water can cause harm to human health. Excessive nitrogen and phosphorus entering the water body leads to eutrophication, excessive growth of algae and other aquatic plants, large consumption of dissolved oxygen, resulting in a large number of fish and shrimp deaths, plant root rot, anaerobic decomposition at the bottom of the water, producing H2S, NH3, mercaptan and other odorous substances, making the water body become "dead water".

(3) Atmospheric pollution: The harmful gases produced in dairy cow production can be divided into two categories. One is greenhouse gases, namely carbon dioxide (CO2) and methane (CH4), which can destroy the ozone layer of the atmosphere and aggravate the greenhouse effect. The other is NH3, H2S, carbon monoxide, etc., which can lead to the deterioration of air quality in cowshed and surrounding environment and affect the health of dairy cows and human beings.

(4) Microbial contamination: There are a lot of harmful microorganisms in cow excreta and waste produced in production, which can be transmitted through breeding mosquitoes and flies or air, and pose a threat to the health of cows themselves and the surrounding population.

Farm environmental governance is a problem in dairy farming.

2. Diseases of digestive tract in dairy cows

Esophageal obstruction is an acute disease caused by sudden blockage of feed or foreign body in the esophageal cavity of cattle. Its clinical features are dysphagia, salivation and rumen swelling. We can reduce this disease by using cow stomach large magnets.
