Exotic, crossbreed cow & buffalo for 5th of pregnancy how much concentrate (other than maintenance)?

Correct option is E

During the 5th month of pregnancy in exotic crossbreed cows and buffaloes, the nutritional requirements increase significantly to support the growing fetus. This higher demand for nutrients, including proteins and energy, necessitates an increase in concentrate feed. Providing 15 kg of concentrate ensures that the pregnant animal receives adequate nutrition for both maintenance and the developmental needs of the fetus during this crucial stage of pregnancy.
