The seasonality of grass-based, seasonal-calving dairy systems results in disproportionately higher labor demands during the spring, when cows are calving, than in the remaining seasons. This study aimed to (1) examine the relationship between labor efficiency and profitability; (2) investigate strategies to reduce the hours worked per day by the farmer, family, and farm staff in the spring by having certain tasks outsourced; and (3) quantify the economic implications of those strategies. Data from an existing labor efficiency study on Irish dairy farms were used in conjunction with economic performance data from the farms. Tasks that required the highest level of farm labor per day in the spring were identified and hypothetical strategies to reduce the farm hours worked per day were examined. A stochastic budgetary simulation model was then used to examine the economic implications of employing these strategies and the effects of their use in conjunction with a proportionate increase in cow numbers that would leave the hours worked per day unchanged. The strategies were to use contractors to perform calf rearing, machinery work, or milking. Contracting out milking resulted in the greatest reduction in hours worked per day (5.6 h/d) followed by calf rearing (2.7 h/d) and machinery work (2 h/d). Reducing the hours worked per day by removing those tasks had slight (i.e., <5%) negative effects on profitability; however, maintaining the farm hours worked per day while utilizing the same strategies and increasing herd sizes resulted in profitable options. The most profitable scenario was for farms to increase herd size while contracting out milking.
基于草饲、季节性产犊的奶牛养殖系统具有季节性,这导致奶牛产犊期间(春季)的劳动力需求不成比例地高于其他季节。本研究旨在:(1)研究劳动效率与盈利能力之间的关系;(2)研究通过将某些任务外包来减少农民、家庭成员和农场员工在春季每天工作时间的策略;(3)量化这些策略的经济影响。本研究使用了爱尔兰奶牛场现有劳动效率研究的数据,并结合了农场的经济绩效数据。确定了春季每天需要最高水平农场劳动力的任务,并研究了减少每天农场工作时间的假设策略。然后,使用随机预算模拟模型来研究采用这些策略的经济影响,以及与每天工作时间不变的情况下按比例增加奶牛数量同时使用这些策略的影响。这些策略是使用承包商来进行犊牛饲养、机械作业或挤奶。外包挤奶可使每天工作时间减少最多(5.6 小时/天),其次是犊牛饲养(2.7 小时/天)和机械作业(2 小时/天)。通过去除这些任务减少每天的工作时间对盈利能力的负面影响很小(即<5%);然而,在维持农场每天工作时间的同时利用相同的策略并增加畜群规模,可以实现盈利的选择。最盈利的方案是农场在承包挤奶的同时增加畜群规模。
