We hypothesized that temperatures above the ther-
mal neutral zone for pigs would decrease feed intake,
BW gain, and carcass quality, whereas increasing spa-
tial allocation would ameliorate some of these changes.
The objectives of this experiment were to determine
the effects of housing temperature at 23.9 or 32.2°C
and spatial allocation of either 0.66 or 0.93 m2
/pig, and
any interaction effects, on growth performance and car-
cass lipid firmness in grow-finish gilts. In addition, we
