QUESTION
The dose rate at which urea is lethal for starved cattle is?
OPTIONS
(A) 1-1.5 g/kg b.wt
(B) 0.22-0.30 g/kg b.wt
(C) 0.33-0.44 g/kg b.wt
(D) None of the above
ANSWER
(A) 1-1.5 g/kg b.wt
EXPLANATION
In starved cattle, approximately 1–1.5 g/kg of urea can be lethal because rapid ruminal conversion to ammonia overwhelms detoxification and causes hyperammonemia. The lower dose ranges listed are below the classic lethal range cited for this specific situation.
