macronutrients and polyethylene glycol on intake of a quebracho
tannin diet by sheep and goats. Journal of Animal Science,
80(12), 3154-3164. We determined if supplemental macronutrients
or polyethylene glycol (PEG) influenced intake of a tannin diet.
Sheep (lambs 5 mo age, 36 kg) and goats (kids 7 mo age, 32 kg)
were fed supplements high in either energy or protein or offered
a choice between the two supplements before and after receiving
a meal containing 15% quebracho tannin. The effect of PEG, a
compound that attenuates the negative effects of tannins, was
assessed by offering PEG while animals consumed the tannin diet
for 4 h/d. Intake of the tannin diet was influenced by both
macronutrients and PEG. Animals that chose their own supplements
or that received the high-pr
