- Abstract
Secondary raw materials from animal slaughter are raw materials rich in proteins, vitamins and minerals, which can be used for the production of animal feed. Recycling post-slaughter raw materials into animal feed is a viable solution that simultaneously addresses waste management, food security, resource conservation, and pollution and climate change mitigation. To this end, the use of secondary animal raw materials as feed can be economically beneficial for slaughterhouses and increase the nutritional value of animal feed. The aim of this article is to present the technology for the production of extruded feed additives based on byproducts and grain crops. The following crops were selected for the study: barley, oats, triticale, wheat bran, wheat; and the following byproducts of cattle and small cattle: lungs, ears, lips and esophagus. 3 experimental options were developed (with the replacement of corn by 7%, 10%, 15% byproducts) on the PE-170 extruder with a capacity of 170 kg/hour. The content of moisture was determined in an MX-50 moisture meter (Japan), protein (GOST 25011), fat (GOST 26183) and ash (GOST 31727), and the amino acid composition of offal were determined (M-04-38-2009). In grain crops, the content of dry matter (GOST 28561-90), protein (GOST 10846-91), fat (GOST 29033-91), fiber (GOST 13496.2), ash (GOST 13979.6-69) calcium (GOST 51429-99), phosphorus (GOST 30615-99) and amino acid composition (M-04-38-2009), nitrogen-free extractives and feed units were determined by calculation. According to the results of the research, the following were gained: when drying, the moisture content of by-products was 55.8 - 77.08%; the highest indicators for the essential amino acid composition of offal were: lung (8.6%), lips (4.1%), ears (8.3%) - leucine, and esophagus (6.4%) - lysine; proteins of animal origin were most contained in offal of category II: lips (22.3%) and ears (23.9%). The results of the study of the composition of feed consumed with the use of cereals and by-products contain a rich nutritional and amino acid composition, and we are recommending it for feeding farm animals. Further research in this area will make it possible to obtain feed additives with high biological value and utilize unclaimed by-products of livestock slaughter.
