Effect of (Azolla Pinnata) Meal Supplementation on Growth Performance, Carcass Traits, and Gut Histomorphology in Commercial Broilers

This study explored Azolla pinnata meal as a sustainable alternative in broiler diets, using 300-day-old broilers. The four treatment groups (A, B, C, D) received 0g/kg, 1g/kg, 2g/kg, and 3g/kg of Azolla meal, respectively. Nutrient digestibility and nutritional analysis ensured a balanced diet. Results showed significant growth improvement, with the 3g/kg Azolla group achieving the most favorable feed conversion ratio (FCR) at 1.66, aligning with sustainability goals. A notable finding was the progressive increase in FCR over five weeks with week three displaying the highest FCR. Moreover, the observation of increasing FCR throughout the five-week experimental period, higher Azolla supplementation correlated with increased ileal villus height, indicating improved nutrient absorption. Consistent crypt depth emphasized Azolla’s specific impact on villus height. One of the distinctive aspects of this study lies in its emphasis on histopathological analysis, a facet that sets it apart from existing research in the domain. These results provide insights into Azolla pinnata meal’s sustainable use in broiler nutrition, promoting growth, feed efficiency, and gut health. In conclusion, 3g/kg Azolla supplementation positively impacted broiler performance, emphasizing its potential in sustainable poultry production.
