This paper aimed at verifying if and to what extent the use of information technologies for dairy farming positively affects productivity of farmed herd. To do this we estimated the effects of precision farming on a productivity index at herd level, utilizing individual farms data of about 500 livestock farms. Farms are specialized in bovine milk production and are localized in Lombardy, that is one of the most important areas of Italian dairy farming. Using a two-stage treatment regression model, to solve the selection bias due to both observed and un-observed individual heterogeneity in the technology adoption, the study found a positive relationship between adopter status and the proxy of herd productivity.
本文旨在验证信息技术在奶牛养殖中的应用是否以及在多大程度上对养殖畜群的生产力产生积极影响。为此，我们利用约500个畜牧场的个体农场数据，估计了精准养殖对畜群水平生产力指数的影响。这些农场专门从事牛奶生产，位于伦巴第大区，该地区是意大利最重要的奶牛养殖区之一。通过使用两阶段处理回归模型，为了解决技术采用中观察到的和未观察到的个体异质性所导致的选择偏差，该研究发现采用者状态与畜群生产力指标之间存在正相关关系。
