Relationship Between Animal Welfare Metrics, Production, Slaughter, and Economic Gain in Poultry Farming

Animal welfare (AW) is increasingly being discussed and mandated in chicken production, both by current Brazilian legislation and by importing markets. Industries continually seek greater financial returns, and within this context, it has been observed that the proper implementation of animal welfare principles effectively reduces losses by minimizing carcass condemnations due to injuries, thereby significantly contributing to in-creased profitability. The economic impact of non-compliance with these welfare standards in broiler production is well documented in the scientific literature. However, the same level of concern is not observed regarding the financial impact on integrated producers, who supply the raw materials. The present study aims to systematically map, contextualize, quantify, and qualitatively analyze articles evaluating the implementation of animal welfare in industrial broiler production and its impact on the financial returns of producers and integrated companies. The primary descriptor used was “animal welfare.” To quantify the relevant articles, the Proknow-C method was applied, followed by a similarity analysis using VoSViewer® software version 1.6.19 for systematic content evaluation. Descriptor combinations were led by animal welfare, followed by broiler pro-duction, poultry production, slaughter, economy, and rural producers. Although a significant number of articles address AW, those focused exclusively on chicken production are far fewer, declining even more when carcass condemnations are considered. Only six studies included the descriptor “economic,” and just three included “producer.” The con-tent of these nine studies was systematically reviewed, with two excluded and seven selected for discussion. Among the seven analyzed studies, none specifically examined the economic impact of AW implementation for the producer, clearly highlighting a significant research gap.
