• Animal Identification Technologies:
• Traditional identification methods include ear tagging, tattooing, and branding (hot-iron or freeze branding).
• Modern, advanced precision technologies encompass:
• Radio-Frequency Identification (RFID): Microchip transponders, RFID ear tags, and rumen boluses enabling automated individual identification.
• Artificial Intelligence (AI) and Computer Vision: Automated facial recognition, muzzle print scanning, and thermal imaging for touchless animal identification and monitoring.
• nalysis:
• In evaluating modern technological options, AI and RFID represent advanced precision tools.

Correct option: (4) (A) only,

• Feeding Standards for Adult Breeding Bulls:
• An adult breeding bull requires adequate nutrition to maintain body condition and support vigorous spermatogenesis and libido.
• In addition to ad libitum maintenance roughage ($20 - 25\text{ kg}$ green fodder and dry straw):
• breeding bull in regular service is fed $2.0 - 2.5\text{ kg}$ of balanced concentrate mixture daily (containing $16-18\%\text{ CP}$ and $70\%\text{ TDN}$).
• nalysis:
• (2.5 kg): Correct standard concentrate allowance.

Correct option: (2) 5kg
