BW = body weight; ME = metabolizable energy; HP = heat production. THP = total heat production; RHP = heat production of resting metabolism; FHP = fasting heat production; AHP = heat production related to physical activity; TEF = thermic effect of feeding; TEFlt = thermic effect of feeding long-term; TEFst = thermic effect of feeding short-term.
a-d Means within a row without a common superscript differ significantly (P < 0.05). Values were means of six observations per treatment. The P-values more than 0.10 were presented with “NS”.
