In this retrospective study, we conducted a desktop-based analysis of published literature using the ScienceDirect™ search engine to determine the proportion of livestock research within the last 7 years (2015–2021) that have applied animal welfare assessment combining objective measures of physiological stress and evaluation of climate change factors in order to provide an account of livestock productivity. From the search results, 563 published articles were reviewed. We found that the majority of the literature had discussed animal production outcomes (n = 491) and animal welfare (n = 453) either individually or in conjunction with another topic. The most popular occurrence was the combination of animal welfare assessment, objective measures of stress physiology and production outcomes discussed collectively (n = 218). We found that only 125 articles had discussed the impact of climate change (22.20%) on livestock production and/or vice versa. Furthermore, only 9.4% (n = 53) of articles had discussed all four factors and published research was skewed towards the dairy sector. Overall, this retrospective paper highlights that although research into animal welfare assessment, objective measures of stress and climate change has been applied across livestock production systems (monogastrics and ruminants), there remains a shortfall of investigation on how these key factors interact to influence livestock production. Furthermore, emerging technologies that can boost the quantitative evaluation of animal welfare are needed for both intensive and extensive production systems.

牲畜应激生理指数、动物福利和气候变化评估一体化的回顾性文献评价



在这项回顾性研究中,我们使用 ScienceDirect™ 搜索引擎对已发表的文献进行了桌面分析,以确定过去 7 年(2015-2021 年)内应用动物福利评估并结合生理应激客观测量的牲畜研究比例评估气候变化因素,以了解牲畜生产力。从搜索结果来看,共审阅了 563 篇发表的文章。我们发现大多数文献都单独或结合其他主题讨论了动物生产结果( n = 491)和动物福利( n = 453)。最常见的情况是将动物福利评估、应激生理学客观测量和共同讨论的生产结果结合起来( n = 218)。我们发现,只有 125 篇文章讨论了气候变化 (22.20%) 对畜牧生产的影响和/或反之亦然。此外,只有 9.4%( n = 53)的文章讨论了所有四个因素,并且发表的研究偏向于乳制品行业。总体而言,这篇回顾性论文强调,尽管对动物福利评估、压力和气候变化的客观测量的研究已应用于整个畜牧生产系统(单胃动物和反刍动物),但对这些关键因素如何相互作用影响畜牧生产的研究仍然不足。此外,集约型和粗放型生产系统都需要能够促进动物福利定量评估的新兴技术。
