Abstract

The objective of this study was to evaluate differences in the technical efficiency of alternative milk production systems on Brazilian farms. Using a panel from 2014 to 2021 (1117 observations of 383 dairy farms) we compare the technical efficiency of more recently adopted Compost‐bedded Pack Barns (CPB) with that of Semi‐confinement (SC), and Unstructured confinement (UNS) systems. A stochastic frontier was estimated by a Generalized True Random Effects to assess the relationship between technical efficiency and the production systems adopted, decompose efficiency into Transient (short‐term) and Persistent (long‐term) components, and control for unobserved heterogeneity. We found that farms using confined systems are more efficient than those using semi‐confined systems. The decomposition of the Overall Technical Efficiency in its Persistent and Transient components suggests that farmers can be more efficient when dealing with short‐term shocks than when deciding which system to use. The use of more capital‐intensive technologies such as CPB may provide opportunities to improve dairy farm profitability and productivity growth in Brazil.

评估堆肥垫式畜舍对巴西奶牛场生产效率的影响

本研究旨在评估巴西牧场替代牛奶生产系统的技术效率差异。我们利用 2014 年至 2021 年的面板数据（对 383 个奶牛场的 1117 个观测值），比较了最近采用的堆肥垫式挤奶牛舍（CPB）与半圈养（SC）和非结构化圈养（UNS）系统的技术效率。采用广义真实随机效应估算随机前沿，以评估技术效率与所采用的生产系统之间的关系，将效率分解为瞬时（短期）和持久（长期）两部分，并控制未观察到的异质性。我们发现，采用封闭系统的农场比采用半封闭系统的农场效率更高。将总体技术效率分解为持续和瞬时两个部分表明，农民在应对短期冲击时比决定使用哪种系统时更有效率。使用 CPB 等资本密集型技术可为提高巴西奶牛场的盈利能力和生产率增长提供机会。

期刊介绍： Agribusiness: An International Journal publishes research that improves our understanding of how food systems work, how they are evolving, and how public and/or private actions affect the performance of the global agro-industrial complex. The journal focuses on the application of economic analysis to the organization and performance of firms and markets in industrial food systems. Subject matter areas include supply and demand analysis, industrial organization analysis, price and trade analysis, marketing, finance, and public policy analysis. International, cross-country comparative, and within-country studies are welcome. To facilitate research the journal’s Forum section, on an intermittent basis, offers commentary and reports on business policy issues.
