“…Oxidative stress is a potential factor associated with immune response itself (Costantini & Møller 2009).

This study was intended to determine the modulatory effects of dietary supplementation of purple sweet potato (Ipomoea batats Poir., PSP) on the immune response of chickens. PSP was included in a basal starter diet by 1% (PSP(L)) or 3% (PSP(H)) and continually fed. Newcastle disease (NDV) vaccine, Brucella abortus (BA) and sheep red blood cells (SRBC) were used for chicken immunization. Antibody titers against these antigens were used to estimate humoral immunity. Concanavalin A (Con A)-induced proliferations of splenocytes, thymocytes and peripheral blood lymphocytes (PBL), ratios of CD4- and CD8-single positive and CD4-CD8-double negative (DN) cells in splenocytes, were both used to indicate cellular immunity. Relative weights of spleen, thymus and bursa and white blood cell (WBC) counts were studied. PSP(H) increased anti-NDV (P < 0.05), anti-BA (P < 0.01) and anti-SRBC titers (P < 0.05) in response to secondary immunization, whereas PSP(L) increased titers of anti-BA (P < 0.05) and anti-SRBC (P < 0.01). Proliferations of splenocytes and thymocytes were augmented with PSP(L) (P < 0.05). PSP(H)-treated chickens had lower (P < 0.05) ratios of CD4-single positive lymphocytes. Proliferation of PBL, weights of lymphoid organs and WBC counts were not affected. These results suggest that dietary PSP supplementation could enhance the immune response after immunization in chickens.

“…Total oxidant status (TOS) was measured as described in humans by Erel (2005) and, more recently, in avian studies (Maurice et al 2009;Travers et al 2010). TOS assesses both HjOj components (that can break down in important prooxidants and can also be indicators of tbe Superoxide dismutase enzyme's activity) and lipid bydroperoxides (markers of prior lipid damage that stUl maintain prooxidant properties; Erel 2005).…”

We investigated the effects of ecological context (by comparing data from two consecutive years) and experimentally manipulated nestling developmental conditions (large vs. small brood size) on immune function (immunoglobulin Y [IgY]) and oxidative stress in nestling European starlings Sturnus vulgaris. On the basis of annual differences in chicks' morphological traits and body masses close to fledging, we established that 2007 was a relative low-quality year and 2008 was a relatively high-quality year. Total antioxidant capacity (TAC) was significantly lower in experimentally enlarged broods, but only in the low-quality year (2007). Total oxidant status (TOS) was independent of brood size in both years but was 45% higher in the low-quality year. Consequently, plasma oxidative status (the ratio between TOS and TAC) was higher in 2007. In contrast, plasma IgY levels were higher in the experimentally enlarged broods and in the high-quality year (2008). Thus, immune function and oxidative stress showed inverse relationships with developmental conditions and annual variation in year quality. Finally, TOS and TAC were positively correlated, but only in the low-quality year (2007), and there was no relationship observed between IgY and markers of oxidative stress. Our results demonstrate the importance of taking into account year effects or ecological context when assessing environmental effects on physiological mechanisms underlying the life-history traits of chicks, such as oxidative stress.
