• Matching Pig Breeds (List-I) with Morphological Characters (List-II):
• Ghurra $\longrightarrow$ (III) Bulldog face: An indigenous pig breed native to Uttar Pradesh; small body size, black/brown coat, with a dished nasal bridge creating a characteristic bulldog appearance.

• Management of Draught Bullocks:
• Training: Training for draft operations (yoking, carting, commands) should begin after 2 years of age when bones and joints have attained adequate structural ossification.
• Regular Working Age: Bullocks should be put to regular agricultural field ploughing after 4 years of age when physical maturity is fully achieved.
• Daily Working Hours: For optimal animal welfare and sustained work output, bullocks should work a maximum of 5 to 6 hours per day (with mandatory midday rest during hot weather).
• Castration Timing: Castration should ideally be performed around 1.5 to 2.0 years (not before 1 year, to permit testosterone-mediated muscular development of the neck and crest). Thus, (B), (C), and (D) are correct.

Correct option: (3) (6), (C) and (0)
