The Effect of Humic Substances on the Content of Copper and Zinc in the Turkey Muscle

Abstract

The aim of the study was to assess the effect of humic substances on the changes of copper (Cu) and zinc (Zn) content in the thigh and breast muscle of turkey. For the trial, 20 turkeys (BIG 6) were allocated into two groups (control group and experimental group) of 10 birds. Experimental group was supplemented with 0.5 % Humac Mycotoxi Sorb (HM). The control group received a basal diet without any supplements. The Humac Mycotoxi Sorb was added to turkey feed for 10 weeks.  In the breast and thigh muscles, we found a statistically significantly higher (P < 0.001) Cu content after the addition of 0.5% HM to the feed (4.43; 4.18 mg.kg-1 ) compared to the control group of turkeys (2.70;3.35 mg.kg-1). Also, in the breast and thigh muscles, were found a statistically significantly higher   (P < 0.05) Zn content after the addition of 0.5% HM to the feed (50.98; 64.42 mg.kg-1 ) compared to the control group of turkeys (44.33; 62.95 mg.kg-1).
