Male non-replacement calves in dairy systems represent an underutilized economic resource for dairy producers worldwide. Despite this, increasing the practice of rearing non-replacement male calves has significant barriers both in on-farm adoption and practice. Poor neonatal rearing practices, higher levels of morbidity and mortality, and disaggregated production pathways with multiple points of handling, have all been described as barriers to adoption of surplus calf production. To identify the critical decision-determining challenges associated with broader adoption of raising non-replacement stock, and to investigate the whole-of-value chain issues faced by dairy producers to rear non-replacement male calves, we undertook a series of semi-structured interviews with Australian dairy producers to interrogate their key challenges. To achieve this, a constructivist grounded theory approach was used to inform the process of analysis of in-depth interviews with Australian dairy producers regarding their current practices and perceptions. Five major themes emerged from these conversations that were key barriers to on-farm non-replacement calf rearing in the producer group participants. These were: impacts of drought on cost and availability of feed for these calves and the whole herd; the management requirements of non-replacement male calves as an additional workload to that of their current operation; their attitudes and current practices to and surrounding euthanasia; perceived ease of supply-chain access for these calves, and their perceptions of the economic value of dairy-beef product as a return on investment. Understanding the barriers to adoption of non-replacement calf rearing, and addressing the value proposition for dairy beef, can assist increased uptake of non-replacement calf rearing. These findings will allow development of strategies to address these barriers, and extension of viable management strategies to increase adoption of profitable business practices surrounding non-replacement male calf production.
奶牛养殖系统中的雄性非留种犊牛,对全球奶农来说是一种未得到充分利用的经济资源。尽管如此,增加非留种雄性犊牛的饲养实践在农场采用和实际操作方面都存在重大障碍。不良的新生犊牛饲养方法(、)更高的发病率和死亡率,以及分散的生产路径和多个处理环节,都被描述为采用剩余犊牛生产的障碍。为了确定与更广泛地饲养非留种牛相关的关键决策挑战,并调查奶农在饲养非留种雄性犊牛时面临的全价值链问题,我们对澳大利亚奶农进行了一系列半结构化访谈,以探究他们面临的主要挑战。为此,我们采用了建构主义扎根理论方法,为分析与澳大利亚奶农就其当前做法和看法进行的深度访谈提供依据。从这些对话中出现了五个主要主题,这些主题是生产者群体参与者在农场饲养非留种犊牛的关键障碍。它们是:干旱对这些犊牛以及整个牛群饲料成本和可获得性的影响;非留种雄性犊牛的管理要求,这是他们当前业务之外的额外工作量;他们对安乐死的态度和当前做法;这些犊牛供应链获取的难易程度,以及他们对奶牛肉产品作为投资回报的经济价值的看法。了解非留种犊牛饲养采用的障碍,并解决奶牛肉的价值主张,有助于增加非留种犊牛饲养量。这些发现将有助于制定应对这些障碍的策略,并推广可行的管理策略,以增加围绕非留种雄性犊牛生产的盈利商业做法的采用率。 注:括号内的顿号为原文疑似遗漏标点,译者根据语境补充。
