Within the framework of the European Union's Common Agricultural Policy (CAP), the Ministry of Agriculture, Agri-food and Food Sovereignty (MAAFS) commissioned an evaluation of the impact of the CAP Strategic Plan (CSP) on animal welfare in France [...] This evaluation was conducted from a thematic perspective focusing on animal welfare and covers the years 2023 and 2024, corresponding to the first two effective years of programme implementation. The evaluation work makes it possible to analyse the contribution of CAP interventions to animal welfare, as well as their coherence and complementarity with other relevant measures. The evaluation was carried out over a 12-month period (January 2025-January 2026) and structured into three phases: the scoping phase (January-March 2025), the data collection and analysis phase (April-September 2025), and the finalisation and recommendations phase (October 2025-January 2026). [...] In recent years, brushes have been increasingly implemented on dairy farms to improve animal welfare, health, and productivity. This study presents a narrative review of scientific studies published over the past decade, selected based on their evaluation of brushing effects on behavioral, physiological, and production parameters in dairy cattle. The evidence consistently indicates that access to brushes increases grooming behavior and is associated with reductions in stress-related indicators, supporting improved animal welfare. In addition, brush use has been linked to improved hygiene and may serve as a non-invasive behavioral indicator of health status, as reduced usage has been associated with conditions such as metritis and lameness. In contrast, evidence regarding productive responses remains more variable. Some studies report increases in milk yield and changes in milk composition; however, these effects are not consistently observed and appear to depend on factors such as animal characteristics, management conditions, brush accessibility, and study design. Overall, brushing appears to be a promising enrichment strategy, but further standardized and long-term research is required to better establish its effects on production and reproductive performance.
