    Effect of Zebu cow urine supplementation on the growth performance of commercial broilers
    (Palampur, 2021-12-28) Sharma, Gunjan; Upadhyay, Sanjiv Kumar
    180 day-old commercial broiler chicks were purchased and randomly assigned to six different nutritional regimens with eighteen subgroups, each treatment had three replicates, and each replicate had ten chicks. The experimental trial was conducted upto 6 weeks. The metabolic trial was conducted on 28th day of experiment for five consecutive days. 2 broiler experimental diets were prepared according to ICAR (2013) standards for all three stages (pre-starter, starter, and finisher). Both diets were adequately balanced to meet the nutrient requirements in terms of calories, protein, vitamins, and minerals. Both diets were isocaloric and isonitrogenous. Diet-1 (ICAR-2013 Standards) was offered to T0, T2, T3, T4, T5 treatment groups and Diet-2 having 0.05% antibiotic (Zn-bacitracin) was offered to treatment group T1. Treatment groups T0 and T1 were given tap water, whereas treatment T2, and T3 were given cow urine fresh (UF) @ 10ml/litre and 20ml/litre respectively and treatment groups T4 and T5 were given cow urine distillate (UD) @ 10ml/litre and 20 ml/litre respectively. The final body weights (g), gain in weights (g) and FCR were significantly (P<0.05) better @ 10ml/litre supplementation of UD (T4) and UF (T2). Similarly, the digestibility of CP was also significantly (P<0.05) higher in T4 and T2 treatment groups, supplemented with UD and UF @ 10ml/litre respectively, whereas the retention of phosphorus was significantly (P<0.05) higher in T4 (@ 10ml/litre UD), T2 (@ 10ml/litre UF) and T5 (@ 20ml/litre UD) treatment groups in comparison to control and other treatment groups. Higher overall gross profit was observed in the treatment groups of broilers supplemented with 10% UF (T2) and 10% UD (T4) in comparison to negative control (T0). Results showed that supplementation of urine didn’t affect the blood biochemistry of the chicks. Overall results showed, improved growth rate and better FCR in birds supplemented with UD and UF at 10ml/litre inclusion. However, 10% UF was found to be more beneficial without exerting any effort and cost.
