Concept:
Indigenous and exotic cattle breeds (Bos indicus and Bos taurus) are systematically categorized based on their geographic origin and primary utility into milch breeds, draught breeds, dual-purpose breeds, and exotic breeds.
Milch breeds are reared primarily for high milk production, draught breeds for agricultural field labor and transport, and dual-purpose breeds for both milk yield and bullock work.
Exotic breeds originated outside the Indian subcontinent and are characterized by very high milk production under intensive management. Step 1: Characterizing Sahiwal (A):
Sahiwal is one of the premier indigenous dairy (milch) breeds of the Indian subcontinent (originating from Montgomery, Pakistan).
It is known for its high milk yield, high butterfat content, and loose skin.
Thus, Sahiwal aligns with IV. Milch purpose breed. Step 2: Characterizing Ongole (B):
Ongole (originating from Prakasam district in Andhra Pradesh) is a prominent dual-purpose indigenous breed.
The cows produce a moderate yield of milk, while the bullocks are powerful, heavy draught animals.
Thus, Ongole aligns with III. Dual purpose breed. Step 3: Characterizing Nagori (C):
Nagori (originating from Nagaur district in Rajasthan) is an exceptional draught breed.
The bullocks are agile, fast, and prized for field plowing and cart pulling, whereas the cows are low milk yielders.
Thus, Nagori aligns with II. Draught purpose breed. Step 4: Characterizing Holstein Friesian (D):
Holstein Friesian (HF), originating from the Netherlands and Germany, is a well-known exotic dairy cattle breed with the highest average milk yield per lactation.
Thus, Holstein Friesian aligns with I. Exotic breed. Step 5: Final Answer:
The matched combination is A-IV, B-III, C-II, D-I, which corresponds precisely to option (B).
