Summary:
The research paper titled "Turmeric on Poultry Production: A Review" discusses the various benefits and effects of using turmeric (Curcuma longa) as a feed additive in poultry production. The review highlights turmeric's multiple pharmacological properties, such as antioxidant, anti-inflammatory, antimicrobial, and antiparasitic effects, which contribute to improved poultry health and performance.
Key Findings:
1. Antioxidative Capacity: Turmeric has strong antioxidant properties, which help reduce oxidative stress in poultry. This reduction is linked to an increase in key enzymes like catalase and glutathione peroxidase, which are crucial for protecting cells from damage and improving overall bird health.
2. Egg Production and Quality: The inclusion of turmeric in poultry diets has shown mixed results in egg production and quality. While some studies reported improvements in egg production and yolk color, others found no significant changes in egg weight or internal quality. However, turmeric may enhance the digestive tract's performance, leading to better egg production.
3. Intestinal Morphology: Turmeric positively affects the intestinal morphology of poultry by promoting deeper crypts and better villus structure, which are indicators of improved nutrient absorption and gut health. This effect is partly due to turmeric's antimicrobial properties, which help maintain a healthy gut microbiota.
4. Feed Intake and Feed Conversion Ratio (FCR): Turmeric supplementation has been associated with improved feed conversion ratios, likely due to increased enzyme activity that enhances nutrient absorption. Some studies also reported an increase in feed intake, possibly due to turmeric's aroma and palatability.
5. Carcass Yield: Turmeric has been shown to improve carcass yield and meat quality in broilers, primarily through its antioxidant activity, which stimulates protein synthesis and reduces fat deposition. This results in leaner meat, which is desirable for both producers and consumers.
6. Biochemical Parameters/Blood Profiles: Turmeric has been reported to lower cholesterol levels in poultry, potentially reducing the risk of conditions like arteriosclerosis. Its antioxidant properties also contribute to better lipid profiles in the blood, enhancing overall bird health.
Benefits of Feeding Turmeric to Poultry:
- Natural Growth Promoter: Turmeric serves as a natural alternative to antibiotics, promoting growth and improving feed efficiency without the risk of developing antibiotic resistance.
- Enhanced Immune Function: The immunomodulatory effects of turmeric strengthen the poultry's immune system, helping them resist infections and diseases.
- Improved Meat Quality: Turmeric contributes to leaner meat production, with better carcass yield and reduced fat content, which are beneficial for consumer health.
- Antioxidant Protection: The strong antioxidant properties of turmeric protect poultry from oxidative stress, which can improve overall health and longevity.
In conclusion, turmeric is a promising feed additive for poultry, offering multiple health benefits and potentially improving production efficiency in a natural and sustainable manner.
