The research paper titled "The Effect of Curcuma longa (Turmeric) on Overall Performance of Broiler Chickens" by S. I. Al-Sultan investigates the impact of turmeric as a feed additive on the performance of broiler chickens. The study tested different levels of turmeric inclusion (0.25%, 0.5%, and 1%) in the diets of broilers and evaluated various performance indicators such as body weight gain, feed conversion ratio, carcass composition, and immune response.
Key Findings:
1. Body Weight Gain: Chickens fed with 0.5% turmeric showed the highest body weight gain (1344.5 g), followed by those with 0.25% (1329.8 g), 1% (1306 g), and the control group (1268.2 g).
2. Feed Conversion Ratio (FCR): The feed conversion ratio was most efficient in the group receiving 0.5% turmeric (2.08), indicating better utilization of feed compared to the control group (2.47).
3. Carcass Composition: The protein content in the breast and thigh muscles remained similar across all groups. However, the fat percentage was lowest in chickens fed with 1% turmeric, suggesting that turmeric may help in reducing fat deposition.
4. Immune Response: Higher bursa and thymus weight indices were observed in the 0.5% turmeric group, indicating enhanced immune function. Additionally, the inclusion of turmeric at higher levels increased both erythrocytic and leukocytic counts, which are indicators of improved immune status.
5. No Adverse Effects: Turmeric did not induce any abnormal flavor, color, or smell in the meat, ensuring that its inclusion does not negatively affect the organoleptic properties of poultry meat.
Benefits of Feeding Turmeric to Poultry:
- Growth Promotion: Turmeric, particularly at a 0.5% inclusion level, promotes better growth in broilers, as evidenced by the highest body weight gain and improved feed conversion ratio.
- Fat Reduction: Turmeric can reduce fat deposition in broiler chickens, which may result in leaner meat, a desirable trait in the poultry industry.
- Immune Enhancement: The study indicates that turmeric enhances the immune system of broilers, making them more resistant to diseases. This is likely due to the immunomodulatory properties of curcumin, the active ingredient in turmeric.
- Antioxidant Properties: The antioxidative properties of turmeric contribute to better health and growth in poultry by reducing oxidative stress, which can otherwise impair growth and immune function.
In conclusion, the use of turmeric as a feed additive, particularly at the 0.5% level, is beneficial for improving the overall performance and health of broiler chickens.
