Effect of treatment on young weaned pig (n = 10 per treatment) rectal temperature (°C). Control treatment (CON) = pigs fed basal diet (0.0% β-mannanase) with saline injection. Enzyme treatment (ENZ) = pigs fed enzyme diet (0.056% β-mannanase) with saline injection. Immune system stimulation treatment (ISS) = pigs fed enzyme diet (0.056% β-mannanase) with LPS (Escherichia coli serotype O55:B5) injection. The arrows indicate days on which either a saline (CON and ENZ) or LPS (ISS) injection were administered at 10:00 h. Rectal temperatures were measured 4 h post-challenge. Data points on d 5 and 8 represent average baseline pre-challenge temperature, and d 10, 12, and 14 represent post-challenge temperatures. Treatment by day interaction P < 0.0001; day P < 0.0001; treatment P < 0.0001; block P = 0.0015
