- ARC/AFRC (UK, 1959) → Net energy-based system, UK livestock.
- Morrison's (USA, 1915) → DCP + TDN basis; commonly used in Indian livestock feeding (also called Modified Wolff-Lehmann standard).
- ICAR (India) → Indian Council of Agricultural Research standard by Dr. S.K. Ranjhan.
Why Other Options Are Wrong
- UK → ARC/AFRC is the UK standard; NRC is American.
