Step 1: Poultry feed requirements.
Poultry birds require energy-rich food grains, proteins, vitamins, and minerals for growth and egg production.
Step 2: Role of maize.
- Maize is the most widely used cereal in poultry feed as it provides a high amount of carbohydrates (energy source), is easily digestible, and relatively cheap in India.
- Rice: Not commonly used as poultry feed in large scale due to cost and availability.
- Wheat: Sometimes used, but less economical and less digestible than maize.
- Oat: Rarely used in poultry feed in India.
Step 3: Conclusion.
Hence, maize is the primary crop used for poultry feed in India.
