Effect of selenium and chromium supplementation on liver profile in growing Vrindavani male calves exposed to thermal stress in Psychrometric chamber

Abstract

Twelve healthy growing Vrindavani male cattle of uniform age and weight (1.5-2 years with 135-185 kg body weight were selected for the study. The animals were used in switch over design. The calves were randomly divided into five groups (6 animals each) viz. Group I (control, maintained in the shed on normal feeding without any treatment), Group II heat stress (HS), Group III (HS+ Chromium (Cr) supplementation), Group IV (HS+ Selenium (Se) supplementation) and Group V (HS+ Cr+ Se supplementation) for monitoring the effect of Cr, Se, Cr+Se supplementation on various group of animal. The Dietary supplementation of Chromium was given @ 0.5mg/kg/DMI/day and Selenium @ o.3mg/kg/DMI/day respectively. The respective groups of animals were exposed to 38 0C in Psychrometric chamber for 6 hours (9:00 AM–3:00 PM) a day. The effect of heat stress on few liver enzymes viz. Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) have been assessed. Blood serum sample was collected at weekly interval for the estimation of ALT and AST. ALT and AST level was significantly (P
