Potential of Livestock By-Products in Agriculture: Opportunities and Risks

A key step before using PPP is to analyze their chemical composition, which includes identifying heavy metals (such as arsenic, mercury, lead, and cadmium), pesticides, and pathogens. Specialists at the Volgograd branch of the Federal Center for Assessment of Safety and Quality of Agricultural Products conducted 132 studies on 13 types of PPP. These tests are aimed at detecting pathogens such as salmonella , as well as helminth eggs and larvae. All studies must be confirmed in accredited laboratories to ensure their reliability. If PPP meets established standards, they can be safely used in agriculture.
The development of processing technologies for PPZ plays an important role in their safe use. Experts have created six technical conditions for the processing of by-products obtained from cattle, small ruminants and horses, which contributes to the standardization of processes and quality control of fertilizers. Processing methods such as composting and biogas technologies help reduce the level of pathogenic microorganisms and increase the nutritional value of fertilizers.
Despite the benefits of using PPZh, improper handling can lead to serious environmental consequences. Unprocessed or insufficiently processed waste can pollute soil and water resources, threatening not only human HEALTH but also ecosystems. Therefore, compliance with all standards and rules for handling PPZh is critically important. This includes not only laboratory studies, but also monitoring environmental safety at all stages of using these products.
Thus, livestock by-products can become a valuable resource in agriculture, but their effective use requires a careful approach and compliance with all necessary standards. Only a comprehensive approach to processing and quality control will minimize risks to human health and the environment, as well as maximize the potential of these resources to improve soil fertility.
