In order to determine the stress response to disbudding, physiological and behavioural response was investigated in disbudded kids and compared with a control group. Disbudded kids (n = 14), were disbudded by thermal cauterisation, and control kids (n = 15) received the same management without being disbudded. Cortisol was measured at -20, -10 and 0 min (pre-treatment), 0, 10, 20 and 30 min as well as 1, 2, 3 and 4 h from disbudding. Frequency and intensity of the behavioural response (kicks, vocalisations) were also recorded during disbudding. Cortisol was higher in disbudded than in control kids during the first 2 h after disbudding. The cortisol area under the curve was 235% higher in disbudded compared to control animals (828 [± 67.4] and 350 [± 65] nmol L−1, respectively). Disbudded kids showed high intensity behaviours in a greater number of animals (100%) and with a greater frequency than controls. These results indicate the presence of acute stress and a potentially painful experience. In conclusion, disbudding in goat kids induces an acute cortisol increase, which lasts for a duration of 2-3 h and a significant behavioural response. This clearly suggests the necessity of using anaesthesia/analgesia to avoid pain and stress.

A common and painful management practice undertaken on most dairy farms is dehorning young calves (also called ‘disbudding’ when done on calves less than about two months of age). Despite much evidence the practice is painful, and effective means available to mitigate this pain, it is frequently performed without pain relief. The overall aim of this study was to describe different stakeholder views on the use of pain mitigation for disbudding and dehorning. Using an interactive, online platform, we asked participants whether or not they believed that calves should be disbudded and dehorned with pain relief and to provide reasons to support their choice. Participant composition was as follows: dairy producer or other farm worker (10%); veterinarian or other professional working with the dairy industry (7%); student, teacher or researcher (16%); animal advocate (9%); and no involvement with the dairy industry (57%). Of 354 participants, 90% thought pain relief should be provided when disbudding and dehorning. This support was consistent across all demographic categories suggesting the industry practice of disbudding and dehorning without pain control is not consistent with normative beliefs. The most common themes in participants’ comments were: pain intensity and duration, concerns about drug use, cost, ease and practicality and availability of alternatives. Some of the participants’ reasoning corresponded well with existing scientific evidence, but other reasons illustrated important misconceptions, indicating an urgent need for educational efforts targeted at dairy producers and dairy industry professionals advising these producers.

The study examined cattle farmers' and veterinarians' opinions of pain-induced distress associated with disbudding and attitudes towards non-steroidal anti-inflammatory drugs (NSAIDs). An emphasis was placed on investigating pain perception, veterinary-client communication and factors influencing analgesic use. Data were collected from an online questionnaire, links to which were published in professional periodicals, promoted by industry organisations and distributed on private practice mailing lists. A total of 110 veterinarians and 116 farmers who regularly disbud calves completed the questionnaires. Of the respondents, 56% of veterinarians and 14% of farmers routinely use NSAIDs for disbudding. Respondents perceived disbudding to be severely painful without medication and 82% of veterinarians and 43% of farmers perceived post-procedural pain to persist beyond 24 h. There was a significant difference between female and male veterinarians' pain scores for disbudding without medication. Veterinarians underestimate the influences of welfare and analgesic duration and effectiveness on farmers' decisions and overrated cost impact. The study highlights that improvements in veterinarian-farmer communication regarding calf disbudding analgesia are required; both in terms of refining veterinarians' understanding of farmers' priorities and guiding clients on methods to improve calf welfare.

Limited scientific literature is available for developing ‘best practice’ guidelines for the management of dairy goats (Capra hircus), particularly goat kids. Disbudding practices for kids and calves appear to be similar; however, it is important to recognise that kids are not small calves. Disbudding causes pain and is performed on calves and kids — welfare concerns surrounding disbudding affect both industries. In this review, we evaluate literature on disbudding of kids and calves and compare methodologies across the two species. In addition, we catalogue behavioural and physiological responses to disbudding and, finally, review alternatives to disbudding (or refinements). Although there may be certain similarities between the response of goat kids and calves to cautery disbudding, it is important to highlight the differences that do exist between the species to reduce the risk of potential detrimental effects (eg brain injury). Cautery disbudding is the most common and efficacious method of disbudding kids and calves; however, kids have thinner skulls and are disbudded at a younger age, which can increase the risk of thermal injury to the brain. Kids and calves show behavioural and physiological responses indicative of pain; however, variability in these responses between studies are likely due to differences in disbudding methodologies, study design and within-species variation. Effective pain mitigation strategies may differ across species; therefore, future research is needed to optimise pain mitigation strategies for kids. Currently, alternatives to cautery disbudding including: (i) selection for polled animals; (ii) managing horned animals; or (iii) the development of novel disbudding methods (eg cryosurgery, clove oil injection) have been deemed unsuitable by the industries as the methods are either impracticable or ineffective. Therefore, if disbudding is to continue, species-appropriate pain mitigation strategies need to be refined. Establishing best practice guidelines for disbudding kids requires managers to recognise that they are not small calves.

Pain is an indicator of welfare status in livestock, and attitudes play a key role in the assessment and treatment of pain in animals. Veterinarians’ and dairy producers’ perceptions of cattle pain are affected by gender, age and work experience. The aim of this paper was to study beef producers’ attitudes regarding disbudding as well as the painfulness of certain cattle diseases. A questionnaire was sent out to 1,000 Finnish beef producers and the response rate was 44%, representing 19% of all Finnish beef producers. Producers graded their attitudes on a five-point Likert scale and perception about pain on an eleven-point numerical scale. Factor analysis was used and four factors were established. These factors described producers’ assessment of disbudding-related pain, their sensitivity to pain in cattle, their willingness to self-medicate disbudded calves and their perceived importance of horns. Factor scores were tested for differences between genders and the use of disbudding on farms with Mann Whitney U-tests. Kruskal-Wallis tests were used to assess differences among producers’ age, work experience and herd size. Female beef producers assessed animal pain higher than male beef producers. Older and more experienced beef producers showed more positive attitudes towards cattle with horns than younger or less-experienced ones. Older beef producers were more sensitive to cattle pain than younger producers and beef producers with a smaller herd size took disbudding pain more seriously and were more sensitive to cattle pain than the producers with larger herds. Producers who did not use disbudding valued horns more than producers using disbudding.

The nature of human–animal interactions is an important factor contributing to animal welfare and productivity. Reducing stress during routine husbandry procedures is likely to improve animal welfare. We examined how the type of early handling of calves affected responses to two common husbandry procedures, ear-tagging and disbudding. Forty Holstein–Friesian calves (n = 20/treatment) were exposed to one of two handling treatments daily from 1 to 5 weeks of age: (1) positive (n = 20), involving gentle handling (soft voices, slow movements, patting), and (2) negative (n = 20), involving rough handling (rough voices, rapid movements, pushing). Heart rate (HR), respiration rate (RR) and behaviour (activity, tail flicking) were measured before and after ear-tagging and disbudding (2 days apart). Cortisol was measured at −20 (baseline), 20 and 40 min relative to disbudding time. There were no significant treatment differences in HR, RR or behaviour in response to either procedure. However, the following changes occurred across both treatment groups. HR increased after disbudding (by 14.7 ± 4.0 and 18.6 ± 3.8 bpm, positive and negative, respectively; mean ± s.e.m.) and ear-tagging (by 8.7 ± 3.1 and 10.3 ± 3.0 bpm, positive and negative, respectively). After disbudding, there was an increase in RR (by 8.2 ± 3.4 and 9.3 ± 3.4 breaths/min, positive and negative, respectively), overall activity (by 9.4 ± 1.2 and 9.9 ± 1.3 frequency/min, positive and negative, respectively) and tail flicking (by 13.2 ± 2.8 and 11.2 ± 3.0 frequency/min, positive and negative, respectively), and cortisol increased from baseline at 20 min post procedure (by 10.3 ± 1.1 and 12.3 ± 1.1 nmol/l positive and negative, respectively). Although we recorded significant changes in calf responses during ear-tagging and disbudding, the type of prior handling had no effect on responses. The effects of handling may have been overridden by the degree of pain and/or stress associated with the procedures. Further research is warranted to understand the welfare impact and interaction between previous handling and responses to husbandry procedures.
