Abstract:
In order to compare the effects of heat stress on serum total protein concentration, the current study examined the effects of selenium and zinc supplementation on total protein concentration during heat stress in Vrindavani cattle. In the study, 12 male animals of age 1 to 1.5 years were randomly allocated into 5 groups (n=6); NHSC (non-heat-stressed control), HS (heat-stressed), HSZ (Heat stressed with zinc @ 100 ppm supplemented), HSS (Heat stressed with selenium @ 1 ppm supplemented) and HSZS (Heat stressed both zinc @100 ppm and selenium @ 1 ppm supplemented).The heat exposure at 38^oC in the psychrometric chamber to heat exposed groups (HS, HSZ, HSS and HSZS) daily for 6 hours (9:00AM-3:00 PM) with duration of 25days washout period prior to subsequent exposure. Blood samples were collected at the end of heat exposure on days 1, 7, 14, 21 and on day 28 (as recovery) for total protein analysis. Two way repeated measure ANOVA followed by Tuckey’s multiple range test was performed between groups at different experimental periods. It was concluded that heat stress negatively affects the oxidative status and effect total protein concentration in serum which can be ameliorated through dietary selenium and zinc supplementation.
