Animal Husbandry

Step 1: Understanding forage preservation.
Green fodder is preserved for cattle either by drying or fermenting: - Drying fodder → Hay. - Fermentation in anaerobic condition → Silage.

Step 2: Analyze the options.
- Hay: Dried grass, not fermented.
- Green manure: Crops grown to be ploughed back into soil, not fodder preservation.
- Silage: Fermented green fodder stored in pits or silos, preserves nutrients for cattle.
- Green cakes: Oil cakes, used as cattle feed but not fermented forage.

Step 3: Conclusion.
Thus, fermented produce of green forage is called silage.

Final Answer:

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.

Final Answer:

Step 1: Recall egg production capacity of breeds.
- White Leghorn: Famous for very high egg production (commercial layer breed).
- Rhode Island Red: Dual-purpose breed (meat + eggs), moderate to high egg production.
- Giriraja: An improved Indian backyard poultry breed, moderate egg production.
- Assel: A traditional breed, mainly used for cockfighting, produces very few eggs.

Step 2: Arrange in descending order.
(A) White Leghorn > (B) Rhode Island Red > (D) Giriraja > (C) Assel

Step 3: Verify with given options.
This order matches Option 1.
