Calf dehorning is a routine husbandry practice on dairy farms that is justified by safety reasons for stockpersons and by a reduced risk of injures among herdmates. In Europe, the practice is regulated by law but little is known about the methods applied or about farmers' attitude to the practice. This study aimed to broaden the existing information on dehorning in dairy holdings by processing results of 639 farm questionnaires gathered in a traditional dairy area of northeastern Italy. Farm questionnaires were stratified according to herd size, type of housing, and productive purpose of the predominant reared breed(s). Chi-squared tests were performed to verify the significant association between a given practice or opinion and the 3 classification factors, and odd ratios were calculated. The outcomes of the study showed that dehorning was carried out on 80% of the surveyed farms, and disbudding was the method reported by all the interviewed farmers. Hot-iron cauterization was the preferred method for disbudding (91%). On average, disbudding was performed at 32 d of age and it was more likely in farms with ≥60 cows than in smaller dairy holdings (OR=7.3). The practice was carried out mainly by farm personnel, but the intervention of a veterinarian was far more likely (OR=5.98) on farms with ≤30 cows than on larger dairies. Most farmers (70%) stated that they had not received any specific training on how to perform disbudding. Fifty-two percent of the respondents reported that disbudding causes prolonged postoperative pain (≥6 h) but pain management was rare. Only 10% of the farmers used local anesthesia before cauterization, and 5% of the farmers provided calves with postoperative analgesia. Consistent with these results, farmers indicated limited willingness to pay the cost of analgesia or to call a veterinarian to perform the procedure. This low motivation of the respondents toward the adoption of practices able to reduce pain related to disbudding might arise from their insufficient knowledge on long-term negative effects of early painful experiences on behavior and handling of dairy heifers. Farmers in favor of keeping horned cows were asked about the reasons for not carrying out dehorning. Aesthetic motivations (54% of respondents) and lack of time (24%) were the main reasons cited. Moreover, a large majority of these respondents (74%) reported no difficulty in handling horned cattle.

In its role as guardian of the Treaties, the European Commission must ensure that Member States enforce EU law within their territories. If adequate enforcement is found to be wanting, the Commission also has the power to take infringement procedures as a corrective measure. The case of Directive 120/2008/EC on the protection of pigs is problematic, as only a few Member States are respecting the ban on routine tail docking, whilst not all pigs are given (adequate) enrichment materials. Twenty-five years after the first EU-wide legal ban on routine tail docking came into force, we are faced with an unprecedented situation that may lead to infringement procedures against more than 20 Member States. This paper describes the various steps that led to the development of the EU law designed specifically to safeguard the welfare of pigs. It lists the numerous efforts (research studies, study visits, recommendations, audits, reports, factsheets, action plans, etc.), undertaken by European decision makers to assist Member States in their efforts to better implement and enforce the relevant rules. Finally, the paper further analyses the current state of play and presents a reflection on possible future scenarios.

Most gait-scoring scales for pigs have a limited number of categories, supposedly to improve repeatability. However, reducing the number of categories could lead to loss of information if the observers' discriminative capacities are underused. With a recently estimated withinherd prevalence of sow lameness of 8.8% to 16.9% in the European Union and the associated losses, the availability of reliable tools for the timely detection of initial cases warrants attention. This study investigated the intra-and inter-observer repeatability (intra-OR and inter-OR) of three gait-scoring scales for sows: a continuous 'tagged' visual analogue scale (tVAS, measured in mm), a 5-point and a 2-point ordinal scale (5P and 2P), all with the same descriptors. Veterinary medicine students (n = 108) were trained to use the scales and then asked to score 90 videos (30 per scale) of sows with normal and abnormal gait. Thirty-six videos were shown once and 18 were randomly shown three times, of which one mirrored horizontally. The students' opinions on the scales were also collected. Intra-and inter-OR were higher with the tVAS than the 2P scale (inter-OR: 0.73 v. 0.60; P < 0.05. Intra-OR: 0.80 v. 0.67; P < 0.05). Intra-OR was higher with the 5P (0.81) than the 2P scale (0.67; P < 0.05). For all three scales, repeatabilities were lower ( P < 0.05) for non-lame sows (gait score of ⩽45 mm on the tVAS) than for sows showing some signs of lameness (gait score > 45 mm). Video order (first 45 v. last 45 clips), mirroring, users' opinions on the scales, and previous declared experience in handling pigs or scoring lameness in other species had no effect on repeatabilities. Correlations between the students' and experts' scores were high (tVAS = 0.92; 5P = 0.91; 2P = 0.88) but the association for the 2P was not linear and the frequency distribution showed lower correlations for a group of students. This study confirms recent evidence that it is possible to design high-resolution gait-scoring scales that do not reduce observer repeatability. Visual gait-scoring scales with fewer than five categories are likely to entail loss of information on lameness in individual sows.
