Study of the nutritional value, chemical and biological safety of feeds obtained from agricultural and industrial waste

Waste from agricultural and industrial production is one of the factors of environmental pollution. Together with this, they are a valuable raw material and can be used, for example, for the manufacture of additional animal feed. The article provides information on the rational use of valuable agricultural and industrial waste as additives in the rations of feeding farm animals and poultry. The health of farm animals and poultry, their productivity depends on the quality and balance of feed. An unbalanced diet leads to metabolic disorders. The data on the chemical composition of molasses, cake and meal, which are used in animal husbandry and poultry farming, as an additional feed with a high protein content, are given. Molasses, which is a by-product of sugar beet production, contains easily digestible carbohydrates, and its use in animal husbandry as an additional feed solves the problem of sugar deficiency. The Testing Center (IC) of the Federal State Budgetary Scientific Institution "FSBSI «FCTRBS-RRVI" conducted research on sunflower cake, rapeseed and sunflower meal in terms of feed value (mass fraction of moisture, mass fraction of crude protein, mass fraction of crude fiber, mass fraction of crude fat). The results of the study of beet molasses samples are presented in terms of quality indicators: mass fraction of dry substances, mass fraction of sugar (by direct polarization), and mass fraction of reducing sugars. The studies carried out indicate that 95% of cake, meal and beet molasses obtained from agricultural and industrial waste, in terms of feed value, meet the requirements of the current regulatory documentation.
