- Abstract
Feed for farm animals is an environmental factor that has a significant impact on various physiological functions, productivity, health, and homeostasis of the body. It is the subject of research in many sciences, including ecology. Scientists in different countries of the world have begun to pay special attention to the study of the ecological safety of animal feed, which is associated with the urbanization of settlements, the development of industry, oil and gas production, accidents on main gas pipelines, mining of coal and gas, the placement of agricultural land by large cars, and livestock farms not far from the developed industrial center of metallurgical complex enterprises, etc., which leads to soil pollution with toxic heavy metals, and then migration and accumulation of elements in plants from the produced feed included in the rations. The aim of the research was to establish the quality and biological completeness of feed rations of dairy cows in enterprises located near environmentally unfavorable anthropogenic objects. The object of research included norms of rations, corn silage, alfalfa haylage, corn turf, fodder beets, grain hay, cereals and legumes hay, alfalfa hay. To conduct a scientific experiment on the production of cow's milk, plant-based feed from four farms located around an industrial city and not far from sources of anthropogenic pollution was selected. Laboratory analysis of selected average feed samples for the content of mineral elements, including toxic metals Cd and Pb, was carried out by the atomic absorption method. Statistical data processing was carried out using the STATISTICA software package version 10.0. The analysis of feed shows not only an increased concentration of heavy metals, but also a low content of vital essential macro- and microelements in plants (feed) against this background, which was typical for all farms. In such conditions, the problem of producing high-quality biologically valuable ecologically safe milk arises. Therefore, in case of local contamination of agroecosystems and ration feeds with heavy metals, especially Cd and Pb, it is necessary to take into account the actual nutritional value of feed, ensure the rationing of essential and non-essential elements in the diet and develop new feed additives, mineral and vitamin premixes of antidote action, homeostasis of an intoxicated organism, increasing the productivity of cows, improving their health status and obtaining environmentally friendly milk. Further research is aimed at constant environmental monitoring of various mineral elements, primarily toxic heavy metals in the feed of farms specializing in milk production in different regions of Ukraine, forest-steppe and Polissya.
