Abstract

Twelve Bufo woodhousii from Lyon County, Kansas, were acclimated to 20 ± 1 C with a 14:10 photoperiod for at least 10 days. Oxygen consumption was measured in each toad at 3, 7, 28, and 120 h after eating an insect meal equal to 5% of the toad's mass. Half of the toads were first measured at 120 h after the meal, and this was followed by a second meal. The rest of the toads were first measured 3 h after the feeding. Oxygen consumption values were significantly higher 3 h after eating than at 7, 28, and 120 h postfeeding. At 3 h postfeeding, oxygen consumption was 1.7 times the value at 120 h after feeding.
