Effects of NAC supplementation on the growth performance of AA-treated piglets (between days 15 and 21 of the trial)

Items	Control	AA	NAC
Average daily feed intake (g/day)	575 ± 3	576 ± 2	572 ± 4
Average daily weight gain (g/day)	301 ± 48	266 ± 69	267 ± 41
F/G (feed: gain)	1.9 ± 0.3	2.3 ± 0.7	2.2 ± 0.3

Data are means ± SD, n = 6. Control = piglets fed the basal diet and received intrarectal administration of sterile saline; AA = piglets fed the basal diet and received intrarectal administration of acetic acid; NAC = piglets fed the basal diet supplemented with 500 mg/kg NAC and received intrarectal administration of acetic acid.
