Effects of NAC supplementation on the colonic growth of AA-induced piglets

Items	Control	AA	NAC
DNA, mg/g	2.93 ± 0.19	3.20 ± 0.44	2.64 ± 0.38
RNA/DNA	4.55 ± 0.78	4.20 ± 1.44	4.45 ± 1.80
Protein/DNA	22.2 ± 3.8b	18.4 ± 1.6a	24.0 ± 3.2b
Protein/RNA	5.30 ± 0.64	4.55 ± 0.66	6.01 ± 1.92

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 administered intrarectally with acetic acid; NAC = piglets fed the basal diet supplemented with 500 mg/kg NAC and received intrarectal administration of acetic acid. ^a-b: Values within a row with different letters differ (P < 0.05).
