We developed an advisory tool addressing 10 critical areas of calf and heifer management, including calving management, care to newborn calves and painful procedures, colostrum management, cow-calf separation, calf feeding, weaning, calf housing, heifer feeding, heifer housing, and general monitoring. Targets and indicators for each critical area were validated by a panel of experts and maximum scores were assigned based on experts' opinions and reviews of scientific literature. The tool was tested on 28 Quebec dairy farms for feasibility and repeatability between 2 observers. Farmers were asked to test colostrum quality, measure blood IgG concentrations, and record health events. The on-farm evaluation included an interview on management practices and an evaluation of conditions in the barn. Scorings and recommendations were discussed with producers. The usefulness of our on-farm welfare tool was evaluated by the producers themselves during a final debriefing. We reached the main goals of a successful advisory tool of calf and heifer management to improve welfare on dairy farms. We respected the targeted time limit of a 3-h visit covering all aspects of our tool including data collection on management and environment, scoring, practical demonstration with producers, and debriefing. We had no problems collecting management- and environment-based data and had high repeatability of qualitative environment-based measures (kappa value>0.6). Our tool helped to detect problems and to discuss these problems with the producers; producers scored below 50% for some targets in calving management, care to newborn calves and painful procedures, colostrum management, and calf feeding. The targets were realistic so producers were not discouraged. All producers were convinced of the usefulness of our tool for identifying areas of calf and heifer management in need of improvement. They were also convinced of the usefulness of our tool as an advisory tool for technical advisors and veterinarians. Six months after the on-farm visit, recommended practices were implemented in many of these areas. Voluntary improvements in animal welfare can be facilitated by using appropriate tools to educate producers and help them change their attitudes toward calf management and animal welfare.
我们开发了一个咨询工具,涵盖了小牛和小母牛管理的 10 个关键领域,包括分娩管理、新生小牛护理和疼痛处理、初乳管理、母子分离、小牛喂养、断奶、小牛饲养、小母牛喂养、小母牛饲养和一般监测。每个关键领域的目标和指标都由专家组进行了验证,并根据专家的意见和对科学文献的审查,为每个关键领域分配了最高分数。该工具在魁北克的 28 个奶牛场进行了可行性和重复性测试,由 2 名观察员进行测试。要求农民测试初乳质量、测量血液 IgG 浓度并记录健康事件。农场评估包括对管理实践的访谈以及对牛舍条件的评估。评分和建议与生产者进行了讨论。在最后的汇报会上,生产者自己评估了我们的农场福利工具的有用性。我们实现了改善奶牛场福利的小牛和小母牛管理咨询工具的主要目标。我们遵守了 3 小时访问的目标时间限制,涵盖了我们工具的所有方面,包括管理和环境数据收集、评分、与生产者进行实际演示以及汇报。我们在收集管理和环境数据方面没有问题,并且定性环境措施的重复性很高(kappa 值>0.6)。我们的工具有助于发现问题,并与生产者讨论这些问题;生产者在分娩管理、新生小牛护理和疼痛处理、初乳管理和小牛喂养方面的某些目标得分低于 50%。这些目标是现实的,因此不会让生产者感到沮丧。所有生产者都相信我们的工具对于确定需要改进的小牛和小母牛管理领域非常有用。他们还相信我们的工具作为技术顾问和兽医的咨询工具非常有用。在农场访问后的 6 个月内,许多这些领域都实施了建议的做法。通过使用适当的工具来教育生产者并帮助他们改变对小牛管理和动物福利的态度,可以促进动物福利的自愿改善。
