“…Widespread adoption by farmers of the addition of an oral NSAID to the procedure currently remains uncertain. However, the use of topical anaesthetic formulation accompanied by intramuscular injections of NSAIDs, administered by beef farmers under veterinary advice, does appear to be increasing in Australia, particularly with recent research confirming both efficacy and productivity improvements with this multimodal approach for use in beef cattle husbandry procedures …”

“…Another study, using 6-8 month-old Bos indicus calves undergoing concurrent castration and amputation dehorning, investigated the use of the topical anaesthetic and buccal meloxicam, without any local anaesthesia, on post-operative weight gain and behaviour. Very little consistent effect of treatment was found on most of the measured behaviours or weight gain over the first 6 days after castration and dehorning (Van der Saag et al 2018b). In a similar study using 6-8 month-old Hereford calves undergoing amputation dehorning alone, there was no clear effect of topical anaesthetic or buccal meloxicam on behaviour, maximum wound temperature or wound morphology after dehorning (Van der Saag et al 2018a).…”

Aims: To compare the effect of a topically applied anaesthetic to no pain relief or meloxicam on the behavioural responses, pain sensitivity and weight gain of calves following disbudding with or without sedation. Methods: A total of 364, 2-6 week-old calves from three commercial farms were systematically allocated to one of six treatment groups. All calves received a cornual nerve block prior to disbudding, with half restrained in a crate and half sedated with xylazine. Within these groups one third received no further treatment (control), one third were treated with meloxicam >10 minutes prior to disbudding and one third received a topical anaesthetic applied to the horn bud wounds following disbudding. The frequency of ear flicks, head shakes, head scratches and pain sensitivity of the wound were recorded on up to eight occasions over 24 hours after disbudding. Calves were weighed before, and 7 and 28 days after, disbudding to determine average daily weight gain (ADG). Results: Compared to calves in the crate-control group, all other groups had reduced ear flicks at all times following disbudding (p < 0.01). Treatment with meloxicam and topical anaesthesia in addition to sedation reduced head scratches compared to calves in the crate-control group (p ≤ 0.013). At 22 hours after disbudding head shakes were reduced in sedated calves treated with topical anaesthetic compared to calves in the crate-control group (p < 0.001). Pain sensitivity was lower in all sedated calves than unsedated calves (p < 0.001). The ADG between Days 0-7 was 0.14 (95% CI = 0.015-0.274) kg/day greater in sedated calves treated with meloxicam than calves in the crate-control group (p = 0.03), and the ADG between Days 0-28 tended to be 0.06 (95% CI=−0.01-0.13) kg/day greater in sedated calves treated with topical anaesthetic than calves in the crate-control group (p = 0.09). Conclusion and clinical relevance: Sedation of calves for disbudding reduced the pain experienced in the following 24 hours. There was a benefit to providing calves with topical anaesthetic following disbudding on behavioural responses and pain sensitivity, which was similar to that of treating calves with meloxicam.

“…Recent research has found that meloxicam-treated, dehorned, 6-to 12-week-old Holstein calves displayed less ear icking for 44 hr and head shaking for 9 hr after dehorning than calves not treated with meloxicam 32 ; moreover, meloxicam signi cantly increased the time spent eating following castration and/or dehorning in 3-month-old Holstein calves 29 . In another study, meloxicam signi cantly reduced the head turning frequency and increased weight gain following castration and dehorning in 6-to 8-month-old beef calves 37 , although clear observations of the effects of meloxicam on other behaviors displayed by 6-to 8-mo-old dehorned beef calves have not been reported 9 . Overall, the changes in behavior suggested that meloxicam was effective in reducing post-surgical pain and distress associated with calf dehorning.…”

“…In addition, changes in behavioral indexes, such as head shake, kick, stamp, ear ick, tail ick, walk, stand, lie, head down, eat and drink [33][34][35][36][37] , can be measured. Average daily gain may also be affected by dehorning in calves 8,38 .…”

The present work aimed to assess the effects of meloxicam on the behavior, feed intake, physiology and pain sensitivity in calves following dehorning. Calves were randomly allocated to four groups: dehorning by amputation with saline (ADNM) or meloxicam (ADM) and chemical disbudding with saline (CDNM) or meloxicam (CDM). Significant differences in the frequencies of all behaviors and activity levels were not observed for the treatment*time interaction (p ≥ 0.05) but were observed for time points (p < 0.05), and the total intake, foraging, hay or milk intake, rectal temperatures, respiration and heart rates and mechanical nonreceptive thresholds (MNTs) in calves were all noted (p < 0.05). For the treatment*time interaction, significant differences were showed between the CDNM and CDM groups in the total intake (at d 0 and 1), foraging (at d 1), hay or milk intake (at d 0 and 1), rectal temperatures (at 24 hr), heart rates (at 4 and 6 hr), and MNTs ( right horn at 2, 6, 24, 48 and 72 hr; left horn at 6 and 24 hr); and significant differences were found between the ADNM and ADM groups in the rectal temperatures (at 6 hr), respiration rates (at 4, 6 and 24 hr), heart rates (at 2, 4 and 6 hr), and MNT (right horn at 2 to 72 hr; left horn at 24 hr). Our results indicated that meloxicam relieves pain after calf dehorning and helps restore feed intake.
