چکیده

رفاه حیوانات یک مسئله مهم در پرورش جوجه‌های گوشتی است. به منظور کاهش میزان مشکلات رفاهی در سیستم‌های متداول پرورش صنعتی، غنی‌سازی محیطی پیشنهاد شده است. غنی‌سازی محیطی با افزایش پیچیدگی محیطی، رفتارهای طبیعی جوجه‌های گوشتی را تحریک کرده و موجب بهبود کیفیت زندگی آن‌ها می‌شود. انواع غنی‌سازی محیطی شامل اجتماعی، فعالیتی، فیزیکی، حسی و تغذیه‌ای است. غنی‌سازی اجتماعی با تقویت تعامل میان پرندگان و انسان‌ها، موجب کاهش استرس و افزایش رفتارهای مثبت می‌شود. غنی‌سازی فعالیتی و فیزیکی با فراهم‌سازی نشیمن‌گاه‌ها، سکوها و موانع، تحرک را افزایش داده و سلامت اسکلتی را بهبود می‌بخشد. غنی‌سازی حسی از طریق محرک‌های مختلف بصری یا شنیداری، واکنش‌های ترس را کاهش داده و رفتارهای طبیعی را تقویت می‌کند. غنی‌سازی تغذیه‌ای نیز با افزودنی‌های خوراکی، یا ارائه تنوع در شکل خوراک‌دهی، نه ‌تنها سلامت گوارشی و ایمنی را ارتقا می‌دهد، بلکه رفتارهای جستجوی غذا را تحریک کرده و رفاه رفتاری را بهبود می‌بخشد. به طور کلی، شواهد علمی نشان می‌دهد که طراحی و اجرای دقیق راهبردهای غنی‌سازی محیطی، می‌تواند به ‌طور هم‌زمان سلامت، رفتار، بهره‌وری و کیفیت گوشت جوجه‌های گوشتی را ارتقا دهد. با این حال، بیشتر ایده‌های غنی‌سازی محیطی برای پرورش‌دهندگان جوجه‌های گوشتی در ایران، نیاز به توسعه و مطالعه بیشتر در رابطه با کاربرد، تأثیر بر رفتار و رفاه، و اقتصاد سیستم تولید دارد.

چکیده [English]

Animal welfare is an important issue in broiler production. In order to reduce the level of welfare problems in conventional industrial breeding systems, environmental enrichment has been proposed. Environmental enrichment stimulates the natural behaviors of broiler chickens by increasing environmental complexity and improves their quality of life. Types of environmental enrichment include social, activity, physical, sensory and nutritional. Social enrichment reduces stress and increases positive behaviors by enhancing interaction between birds and humans. Activity and physical enrichment increases mobility and improves skeletal health by providing perches, platforms and obstacles. Sensory enrichment reduces fear responses and enhances natural behaviors through various visual or auditory stimuli. Nutritional enrichment also promotes digestive health and immunity by adding feed additives, or providing variety in the form of feed, but also stimulates foraging behaviors and improves behavioral well-being. Overall, scientific evidence suggests that carefully designed and implemented environmental enrichment strategies can simultaneously improve the health, behavior, productivity, and meat quality of broiler chickens. However, most environmental enrichment ideas for broiler chicken farmers in Iran require further development and study regarding their applicability, impact on behavior and welfare, and economics of the production system.
