Abstract:
A study was conducted to compare the efficacy of native and crossbreed cow urine distillate (CUD) on performance of broilers during hot summer (May-June) using day old broiler chicks (n = 80) with twenty birds in each group. Control group T-1 was given drinking water without cow urine distillate, while groups T-2, T-3 and T-4 were provided drinking water mixed with cow urine distillate of Ongole, Sahiwal and Holstein Friesian (H.F) crossbred, respectively @10ml/liter. Higher feed intake, body weights, body weight gain and lower feed conversion ratio was observed in groups given native breed cow urine distillate (T-2 and T-3) followed by T-4 (H.F crossbreed cow urine distillate) and T-1(Control). Overall, oxidative stress was decreased and antioxidant status was improved in group T-2 followed by groups T-3, T-4 and T-1. A 25% reduction of malondialdehyde (MDA) concentration in hemolysate on 42nd day in cow urine distillate treated groups was noted. Significantly higher superoxide dismutase (SOD) activity was observed on 42^nd day in groups T-2 and T-3 (0.47 and 0.39 U/mg protein) compared to T-1 and T-4 (0.26 and 0.29 U/mg protein). The results of the experiment concluded that supplementation of cow urine distillate from Ongole and Sahiwal breed of cows was more efficient in reducing the oxidative stress and giving higher antioxidant effect compared to Holstein Friesian crossbred.
