Dietary supplementation with Artemisia argyi extract on inflammatory mediators and antioxidant capacity in broilers challenged with lipopolysaccharide

Abstract: This study investigated the effects of Artemisia argyi extract (AAE) on broilers challenged with lipopolysaccharide (LPS). A total of 96 Arbour Acres broilers (1-d-old) were assigned to a 2 Â 2 factorial arrangement with two dietary treatments (AAE at 0 or 1000 mg/kg) and two immunological challenge treatments (saline or LPS). On d 14, 16, 18 and 20, the broilers were injected intra-abdominally with LPS solution at 500 lg/kg of body weight or an equivalent amount of sterile saline. Blood, liver, spleen and sma… Show more

“…These increases might be because that LPS, as a nonspecific immunogen, could induce immune stress in animals and damage immune organs. The current results in the spleen indices were consistent with the previous ones ( Li et al, 2015 ; Liu et al, 2015 ; Zhang et al, 2020 ). As an essential lymph organ, the spleen can activate lymphocytes after LPS injections, further increasing the number of lymph nodes in the white pulp, the inflammatory cytokines, and the activity of the organ.…”

“…Nevertheless, when the addition amount reached 3% in the present study, MDA levels in liver and serum were significantly increased while serum GSH-Px levels were significantly reduced. However, there was a report that 1% A. argyi extract supplementation tended to increase the activities of serum GSH-Px and CAT, but significantly reduced serum MDA level in broilers ( Zhang et al, 2020b ). These results illustrated that laying hens may have a greater sensitivity to A. argyi than broilers and a 1% addition helps to enhance the antioxidant function, but when increased to 3%, this function is impaired.…”

“…According to the method reported by De Oliveira and Lara (31), the chicken houses were illuminated by LED lights that provide 30-40 lux of light intensity. The lighting scheme included 23 h lighting (L):1 h darkness (D) (23L:1D, days 0-3), 10 L:14 D (days 4-21), 14 L:10 D (days 22-28), 18 L:6 D (days [29][30][31][32][33][34][35], and 23 L:1 D (days 36-42). The temperature of the experimental room was set at 32-34 • C for the first 3 days and then gradually reduced by 3 • C every week, and a final temperature of 21 • C was reached.…”

“…Furthermore, aqueous and alcoholic extracts of A. annua improved insulin resistance via decreasing TNFalpha and IL-6 in high-fat diet/streptozotocin-induced diabetic mice (27). Our previous study found that Artemisia argyi and Artemisia ordosica aqueous extract could improve the immune and antioxidant status of LPS-induced broilers (28,29). Given these features, the present study used water as a solvent to extract the bioactive components of A. annua, and aimed to investigate the effects of A. annua aqueous extract on intestinal immune function, and antioxidant capability in broilers.…”
