Immuno-physiological role of exogenous enzymes supplementation in heat stressed growing calves.

ABSTRACT: Twenty Crossbred (Baladi× Brown-Swiss) male growing-calves, 6 to 8 months old, weighing an average of 115 to 125 kg were subjected for evaluating ZADO supplementary effects on blood biochemical parameters, antioxidant status, thyroid activity, and growth efficiency of calves under semi-arid conditions. The experimental units were pinned equally in two groups. The control (G1) fed the basal ration, and the 2nd, treatment group (G2) fed the basal ration + a daily supplement of 10 g ZADO (exogenous enzymes) calf^- 1 day^- 1 in a powder form mixed well with ration. The results showed that ZADO treatment reduced (P < 0.001) each of respiration rate (RR), rectal temperature (RT), serum malondialdehyde (MDA), urea, creatinine, and cortisol. Also, caused a marked decline in oxi
