Abstract
The recommended dietary intakes for the chelated metal proteinates containing copper in various bound forms, organic and inorganic, at different levels have been proven in an experiment with young fattening pigs. Compound feed enriched with copper sulfate at the rate of 40 g per t was fed to the tested animals in the control group. The animals in the first experimental group received compound feed supplemented with the element indicated above (in the form of copper sulfate) at a dose rate of 20 g/t. The animals in the second and third experimental groups were given the chelated copper complexes at the levels of incorporation of 50 and 100 g/t of compound feeds. The surveys have determined that the optimum rate of inclusion of organic copper into the compound feed for young fattening pigs is 50 g per t. This has the potential to improve the protein digestibility by 1.82%, which is followed by increases in the average daily liveweight gains and the carcass meat yields by 4.5 and 2.2%, respectively. Significant deposits of iron, copper, zink, and manganese in the liver, the longissimus dorsi muscle, and the tibia of the experimental animals fed compound feeds supplemented with the indicated microelements are detected. Histological sections of the small intestine mucosa have indicated that the use of organic copper can contribute to the development of the villus height and the crypt depth and, thereby, improve the digestive and absorptive functions of the intestine. Intensification of the biochemical processes in blood and tissues of the liver and the stomach occurs, which can potentially contribute to increasing the young pig production by 4.5%.
