Poultry by-products as a basis of combined meat and vegetable feed for domestic animals

Abstract

Abstract The use of poultry by-products remains one of the urgent strategies of the economic efficiency increase for a variety of reasons. The most effective is the by-products processing into the meat and bone meal with a high content of amino acids, fatty acids, vitamins and minerals and consequently with high nutritional value. This meal may be used individually and as a basis of the combined feed for domestic animals. The possibility of using poultry by-products as a basis for feed of domestic cats and dogs was studied. The quantitative and qualitative assessment of carcass after the duck Anas platyrhynchos domesticus manual deboning was carried out, and the moisture, proteins and fats content was determined by conventional methods. It was shown that the duck carcass had high nutritional value and can be used as a basis for domestic animals feed. Drawing up a recipe of the combined feed including duck carcass meal, additional protein sources and natural vegetables was carried out. The developed calculation and optimization computer program “Optipet” for the combined feeds recipes optimization was used, which allowed to determine the minimum cost value of the combined feed as required by current law documentation.
