ANALYSIS OF FACTORS OF INFLUENCE ON THE QUALITY OF COMPOUND FEED DURING ITS STORAGE

Abstract

 Ensuring the most effective use of compound feed when feeding animals depends on the level of balance of nutrients in the composition of the manufactured feed and the conditions for its storage. Solving this problem is an urgent problem for both modern feed manufacturers and consumers of such products. The increase in the various prescription components of compound feed, taking into account the age of animals and their industrial purpose and the growth of requirements for their quality, necessitate not only the manufacture of a homogeneous mixture, but also determine the requirements for the conditions of their storage period without compromising quality. The homogeneity of the manufactured feed and the action of external factors have a significant impact on their feed quality, as well as changes in the structure of vitamins, micro and macro elements contained in the feed. It should be noted that the change in the quality of the compound feed occurs along the line of the physical characteristics of the compound feed, i.e. its density, granulometric composition, bulk density, as well as the duration of storage of mixed fodders, is significantly influenced by the index of the frequency of air exchange in the space between particles and others. The off-duty ratio during storage of mixed fodder with the introduction of active ventilation of bulk components has a significant impact on the process of intensive evaporation of moisture I B into the environment and it is characterized by an indicator of the active moisture transfer surface Fm2, taking into account the difference in saturated water vapor pressure. During the storage of compound feed, accumulation of water is observed due to the sorption of water from water vapor in the air. Understanding the factors that determine the change in the quality of compound feed during its storage is an important element in the manufacture and use of compound feed.
