QUESTION
When we subtract faecal energy from gross energy (GE) we will get?
OPTIONS
(A) GPO
(B) NE
(C) ME
(D) DE
ANSWER
(D) DE
EXPLANATION
Gross energy minus fecal energy gives digestible energy (DE). Metabolizable energy requires further subtraction of urinary and gaseous energy losses, while net energy requires additional accounting for heat increment; therefore neither ME nor NE is obtained directly from GE minus fecal energy.
