• Vertical Integration in Livestock Agribusiness:
• Vertical integration occurs when a single commercial enterprise controls two or more successive stages of the production, processing, and marketing chain.
• Hatchery-Broiler Contract Farming: The classic textbook example (e.g., Suguna, Venky's) where an integrator owns feed mills, breeding stock, and hatcheries, supplying day-old chicks and feed to contract farmers, and buying back finished broilers for processing and marketing.

Correct option: (2) Hatchery-broiler farming

• Assertion (A) is Correct: In agricultural enterprise financial planning, achieving an early Break-Even Point (BEP) (where total revenue equals total fixed and variable costs) minimizes operating risk and ensures early solvency.
• Reason (R) is Correct: An early BEP means cash inflows recover capital outlays faster, reducing the discounted payback period and resulting in a higher Internal Rate of Return (IRR).
• Relationship: (R) is the precise financial principle that makes an early BEP desirable in enterprise evaluation.

• Farrowing Index in Swine Production:
• Defined as the number of litters (farrowings) produced per sow per year:

• Impact of Early Weaning: Weaning at 21 days instead of 56 days reduces the farrowing interval from $\sim 175\text{ days}$ down to $\sim 142\text{ days}$, increasing the farrowing index from $2.0$ to $2.2\text{--}2.4$ litters/year.
• Directly governs the biological and financial productivity of the sow herd.
• Conclusion: Statements (A), (B), and (D) are correct.

Correct option: (1) (A), (6) and (D) only.
