Approaches for raising calves vary across commercial dairy farms and relate to behavioral opportunities and animal welfare. The objectives of this study were to evaluate how US dairy producers and calf managers perceive (1) the welfare implications of varying management practices (including social housing and milk allowance) and behaviors in dairy calves, and (2) aspects of the human-animal relationship in calf rearing and relationships with on-farm management and personal calf handling habits. Survey questions were primarily quantitative (e.g., Likert scales) and addressed how common calf management practices and observed calf behaviors were related to aspects of welfare, including calf health and comfort. We additionally posed questions addressing respondent habits, management protocols, and perceptions related to human-animal interaction. Responses from 93 dairy producers and calf managers were collected via digital surveys. Social housing was viewed as being generally positive for both calf comfort and health, although this view was stronger with respect to calf comfort. Respondents from farms using social housing (56%) had more positive perceptions of social housing, viewed social play as being associated with better calf comfort and health, and considered access to other calves and "freedom to express natural behavior" as being more important for calves, compared with respondents from farms not providing social housing. Providing greater milk allowances (>7.6 L/d) was viewed as being good for both calf comfort and health, although respondents from farms providing these milk allowances (59%) had more positive perceptions than those who provided lesser allowances. Abnormal oral behaviors were viewed as being associated with both poor calf comfort and health. The welfare importance of various resources which may reduce abnormal oral behaviors (including hay and brushes) was perceived more ambiguously, although respondents from farms providing these resources, compared with those who do not, generally viewed them as more preferred by calves. We observed a positive relationship between how respondents perceived the human-animal bond (i.e., that calves enjoy contact with humans) and stated personal behavior related to calf contact (frequency of contacting calves to scratch or pet them). Respondent demographics were not related to perceptions of the human-animal relationship, but respondents identifying as female described more frequent positive calf interactions. Described aspects of human-animal interactions were not related to implementation of social housing on-farm. Job satisfaction was positively related to perception of the human-animal relationship. Overall, these results suggest that most calf management personnel place a high value on calf welfare, although farms implementing social housing appear to place a greater value on subjective calf well-being, and individual perceptions of animal welfare may depend on practical experience.
奶牛场饲养小牛的方法因商业奶牛场而异,与行为机会和动物福利有关。本研究的目的是评估美国奶牛生产者和小牛管理者如何看待(1)不同管理实践(包括社会住房和牛奶津贴)和奶牛小牛行为对福利的影响,以及(2)在小牛饲养和与农场管理和个人小牛处理习惯的关系中动物与人类关系的各个方面。调查问题主要是定量的(例如,李克特量表),并涉及奶牛管理实践和观察到的小牛行为与福利方面的关系,包括小牛的健康和舒适度。我们还提出了一些与 respondent 习惯、管理协议和与动物互动相关的感知相关的问题。通过数字调查收集了 93 名奶牛生产者和小牛管理者的回复。社会住房被认为对小牛的舒适度和健康都有积极的影响,尽管在舒适度方面的看法更为强烈。使用社会住房的农场的受访者(56%)对社会住房的看法更为积极,认为社交游戏与更好的小牛舒适度和健康有关,并认为与其他小牛接触和“自由表达自然行为”对小牛更为重要,而不提供社会住房的农场的受访者则认为。提供更大的牛奶津贴(>7.6 升/天)被认为对小牛的舒适度和健康都有好处,尽管提供这些牛奶津贴的农场的受访者(59%)比提供较少津贴的受访者的看法更为积极。异常口腔行为被认为与小牛的舒适度和健康都有关系。各种资源的福利重要性可能会减少异常口腔行为(包括干草和刷子),尽管与不提供这些资源的农场相比,提供这些资源的农场的受访者普遍认为它们更受小牛的欢迎。我们观察到受访者对人与动物关系的看法(即小牛喜欢与人接触)与他们与小牛接触的个人行为(接触小牛以挠痒或抚摸它们的频率)之间存在正相关关系。受访者的人口统计学特征与对人与动物关系的看法无关,但自认为是女性的受访者描述了更频繁的积极小牛互动。描述的人与动物互动方面与农场实施社会住房无关。工作满意度与对人与动物关系的看法呈正相关。总的来说,这些结果表明,大多数小牛管理人员非常重视小牛的福利,尽管实施社会住房的农场似乎更重视小牛的主观幸福感,而个人对动物福利的看法可能取决于实际经验。
