Abstract The liquid nitrogen cryotherapy was evaluated for cryosurgical disbudding in sixty clinically healthy crossbred calves of either sex, aging between 03 to 07 weeks, at −10°C or −20°C cryofreezing using overlapping freezing-thawing and double cycles of freezing followed by thawing, with or without the use of anaesthesia. Six calves each were used for evaluation of two different modalities at two different levels of cryofreezing with or without the use of anaesthesia. Ketoprofen @ 2 mg/kg body weight, i/m was given as preemptive analgesia. The calves were sedated additionally using Xylazine @ 0.2 mg/kg body weight, i/m. Later, under cornual nerve blockade the calves were subjected to cryofreezing as per experimental design. The horn buds showed progressive tendency of drying and sloughing, which later got detached from the site around 2830 days following cryosurgical disbudding indicating a complete healing. The animals subjected to −20°C cryofreezing using overlapping freezing-thawing modality showed comparatively lower rate of recurrence.
