Values are means ± s.e.m. (N=8)
Values for a specific parameter that share different superscripts are significantly different at P<0.05, determined by a two-way ANCOVA and LSD post-hoc tests
DFI, dry food intake; GEI, gross energy intake; DEI, digestible energy intake; T, temperature; L, lactation; ns, not significant
