Abstract
To assess the performance of kids under different disbudding pre-medication regimes, 24 kids of 14–15 days were randomly designated as D0 (control, no medication), DL (local anaesthetics, 2% lignocaine, 1 ml/bud as cornual nerve block), DM (non-steroidal analgesic, meloxicam with 0.25 mg/kg body weight by I/M route) and DL + M (both lignocaine and meloxicam) with six in each group. First fortnight after hot-iron disbudding, ADG was higher (P < 0.05) in DM than control. FCR was significantly (P < 0.05) better in DM and DL over control. PER was non-significantly higher in DM, DL and DL + M over control by 24.86%, 22.70% and 17.84%, respectively. Hb and PCV was higher (P < 0.01) in DM followed by DL, DL + M and D0. Neutrophil, lymphocyte, eosinophil and basophil counts were higher in DL than other treatment groups. Neutrophil-to-lymphocyte ratio was higher (P < 0.01) in DM than other treatment groups. Effect of disbudding pre-medication on serum biochemistry like glucose, total protein, albumin and globulin was significantly affected (P < 0.01) by pre-disbudding treatments among different groups. During entire study period, serum cortisol was lower (P < 0.01) in DM, T3 was higher in D0 and T4 was higher in DL than other groups; however, TSH was lower (P < 0.01) in DM than other three groups. It was concluded that non-steroidal analgesic–medicated kids had better performance and disbudding distress persists up to 15 days irrespective of different pre-disbudding medication regime.
