Key points of pollution Prevention and Control in Livestock and Poultry breeding Industry

The system and measures of industrial pollution control should not be simply adopted to strengthen the prevention and control of environmental pollution in livestock and poultry breeding industry. The key to pollution prevention and control measures is to cure the "root cause", and the pollution of livestock and poultry breeding industry focuses on prevention.

1. Improve the method of culture

The scientific improvement of breeding methods is beneficial to the prevention and reduction of pollution. The nutrition regulation of the feed used in the breeding process is a way to cure the "root". Through the scientific allocation of feed nutrients, the bioavailability of feed can be improved, thus the organic matter in excreta can be reduced. Nutrition regulation can be achieved by stage feeding, low-protein diet, synthetic amino acid application, the use of enzyme preparation to improve nutrient utilization and so on.

II. Rational formulation of policies

Compared with the improvement of culture methods, the reasonable formulation of policies will play a greater role in the process of pollution prevention. Formulate laws and regulations or standards for environmental access of farms. For example, setting the minimum distance between the farm and the surrounding residents, and establishing pollutant discharge standards will help to reduce the pollution degree of livestock and poultry breeding.

III. Optimize the structure

Rational distribution, limiting breeding scale and optimizing animal husbandry structure are effective measures to prevent livestock and poultry pollution. In the United Kingdom, for example, animal husbandry mainly raises cattle, pigs and poultry. The British animal husbandry industry does not pursue super-large-scale, and large dairy farms generally do not exceed 500. Because they mostly adopt a small-scale feeding model, manure and urine direct fertilization is the main treatment measure, the use of special fertilizer vehicles to apply fertilizer fields directly.
