Effects of chromium ultra-fine particles on the pancreas enzyme system of calves

Abstract

Abstract Chromium has an excessively low digestibility and absorption of organic (25%) and inorganic (3%) forms, while the absorption of Cr+3 occurs mainly through the kidney Cr - 80-95%, with small losses in the hair, through the sebaceous gland and bile (45% Cr), indicating a rapid absorption and recreation of Cr. Calves of the control group received the BD, and chromium nanoparticles in a dose of 200 mg/kg were additionally introduced to the diet of the experimental animals. Adding Cr to calves rations is accompanied by an increase in glucose concentration by 10.6% (p≥0.05), triglycerides by 14.3%, while cholesterol is reduced by 16.9%. The highest activity of protease and lipase was established in the first hours of selection, followed by its decrease by 3 hours. Adding chromium to the diets of bulls stimulated protease activity during all record periods, the difference with control was from 25 to 43% (p≥0.05). Characteristic is the enhancement of protease activity on the 2nd day of the experiment, followed by a decrease in its activity by 3 day. Similarly, lipase activity is formed; the difference with the control is 36% (p≥0.05). On the contrary, amylase activity decreases at hourly sampling points and increases in daily sampling.
