The study evaluated the impact of relaxation music on the production performance, welfare, and blood parameters of broiler chickens. Literature indicates that specific music genres, as environmental enrichment, can improve animal welfare and production outcomes. The research involved 1,200 Ross 308 chickens divided into control (C) and experimental (M) groups. The rearing period lasted 42 days, and was conducted according to the flock management guide (Aviagen, 2019). The M group was exposed to relaxation music (Weightless by Marconi Union), played for two hours daily (08:00-10:00) and for 30 minutes before slaughter, at 70 dB. Body weight, feed consumption (FCR), mortality, and rearing conditions (litter pH, harmful gases) were monitored. On day 35, excreta samples were collected to analyze cortisol concentrations and assess welfare. Blood was also collected at slaughter for analysis. Statistical analysis was performed using SPSS software (PS IMGO PRO 8.0). Significantly higher final body weights and lower FCRs were observed in the M group chickens (p ≤ 0.05). Enriching the chickens' environment with relaxation music also resulted in lower cortisol concentrations in excreta samples and improved welfare levels (p ≤ 0.01). Blood analysis of the M group showed a significant increase in the average number of red blood cells and the calcium content, while glutamate dehydrogenase (GDH) concentrations were lower (p ≤ 0.01). The hematocrit percentage, total protein, and uric acid concentrations were significantly lower in the M group compared to the C group (p ≤ 0.05). Litter pH monitoring showed significantly lower pH values for the M group on days 22 and 35 (p ≤ 0.01 and p ≤ 0.05, respectively). However, on day 10, litter pH was lower for the C group chickens (p ≤ 0.05). No significant differences were found for the other results. Relaxation music can serve as environmental enrichment for broiler chickens, potentially improving their production performance and welfare quality. However, further research is necessary to verify the mechanism behind these effects.
该研究评估了舒缓音乐对肉鸡生产性能、福利状况及血液参数的影响。文献表明，特定音乐类型作为环境富集手段，可改善动物福利及生产成果。该研究涉及1200只罗斯308肉鸡，分为对照组（C）和实验组（M）。饲养期持续42天，按照鸡群管理指南（安伟捷公司，2019年）进行。M组暴露于舒缓音乐（马可尼联盟乐队的《失重》）中，每天播放两小时（08:00 - 10:00），屠宰前30分钟播放，音量为70分贝。监测了体重、采食量（料肉比）、死亡率及饲养条件（垫料pH值、有害气体）。在第35天，收集粪便样本分析皮质醇浓度并评估福利状况。屠宰时也采集血液进行分析。使用SPSS软件（PS IMGO PRO 8.0）进行统计分析。M组鸡的最终体重显著更高，料肉比更低（p≤0.05）。用舒缓音乐丰富鸡的环境还导致粪便样本中皮质醇浓度降低，福利水平提高（p≤0.01）。M组的血液分析显示红细胞平均数量和钙含量显著增加，而谷氨酸脱氢酶（GDH）浓度更低（p≤0.01）。与C组相比，M组的血细胞比容百分比、总蛋白和尿酸浓度显著更低（p≤0.05）。垫料pH值监测显示，M组在第22天和第35天的pH值显著更低（分别为p≤0.01和p≤0.05）。然而，在第10天，C组鸡的垫料pH值更低（p≤0.05）。其他结果未发现显著差异。舒缓音乐可作为肉鸡的环境富集手段，可能改善其生产性能和福利质量。然而，有必要进一步研究以验证这些影响背后的机制。
