ABSTRACT
The aim was to investigate the effect of glutamine (Gln) on broilers challenged with Salmonella Enteritidis. 240 1-day-old birds were divided into four groups in a completely randomized design, each of which included 6 replicates with 10 birds per replicate. Group I served as the unchallenged, untreated control (CON). All birds in groups II (SCC) - IV were challenged with 2.0 × 104 CFU/mL of S. Enteritidis. Birds in group III and IV were treated with 0.5% (Gln 1) and 1.0% (Gln 2), respectively, of Gln. The results indicated that S. Enteritidis infection led to a decrease in the average body weight at d 7, 14, and 21 (p 0.05). Chickens fed the Gln showed improved average body weights in comparison with the SCC group (p 0.05). At d 4, 7, 14, and 21, the Gln groups increased digestive enzyme (trypsin, lipase and amylase (except the amylase activity of jejunum at d 14 and d 21)) activities in the intestine (p 0.05), superoxide dismutase (SOD) (at d 14 jejunum; except at d 4, ileum) and catalase (CAT) (at d 4, and d 21, jejunum; d 4, ileum) activity in the serum (except at d 14) and intestinal mucosa (p 0.05), and the mRNA expression of SOD, CAT and nuclear respiratory factor 2 (Nrf2) of the intestinal mucosa compared with the SCC group (p 0.05). These results suggest that Gln as a feed additive could be effective for reducing the detrimental effects of S. Enteritidis infection of broilers.
