“…Similar effects were found in the plasma of hen chicks supplemented via the diet with supra-physiological VE doses [19], but are not consistent with those found in great tit nestlings, where neither plasma TAC nor TOS differed between experimental groups after administration of VE-enriched food [20]. Although our previous studies showed that VE supplementation exerted positive effects on morphological traits of chicks hatched from third-laid VE-injected eggs [15], the significant effect on TAC and TOS was independent of egg laying order, suggesting that all chicks benefited from VE supplementation.…”

Oxidative stress experienced during early development can negatively affect diverse life-history traits, and organisms have evolved complex defence systems against its detrimental effects. Bird eggs contain maternally derived exogenous antioxidants that play a major role in embryo protection from oxidative damage, including the negative effects on telomere dynamics. In this study on the yellow-legged gull (Larus michahellis), we manipulated the concentration of vitamin E (VE) in the egg yolk and analysed the consequences on oxidative status markers and telomere length in the hatchlings. This study provides the first experimental evidence that, contrary to the expectation, a physiological increase in yolk VE concentration boosted total antioxidant capacity and reduced the concentration of pro-oxidant molecules in the plasma, but did not reduce telomere attrition or ameliorate oxidative damage to proteins and lipids in the early postnatal period.

“…Oxidative stress commonly defined as the imbalance between the production of reactive oxygen species (ROS) and the antioxidant capacity of the organism is deleterious to the structure and function of the cell and tissue, which is widely believed to be involved in many diseases [18] [19]. Therefore, antioxidant capacity prioritizing self-maintenance in animals plays a key role in maintaining their health [20].…”

Immune function and antioxidant defense play an important role in protecting animals against pathogens and in controlling oxidative stress, respectively. Aldicarb is of great concern for human health due to its toxic nature, its extensive usage and consequent pollution. The hypothesis that aldicarb exposure would suppress immune function and antioxidant capacity in Kunming mice was to be tested in the present study. Twenty-three adult male mice were randomly divided into the control (n = 11) and the aldicarb treated (n = 12) groups. Food and water were provided ad libtum for both groups, while the aldicarb treated mice drank aldicarb solution (0.097 mg/L) for 22 days. Cellular immunity assessed by phytohaemagglutinin (PHA) response did not differ between the control and the aldicarb treated groups. Similarly, white blood cells were not influenced by aldicarb treatment. Moreover, aldicarb exposure had not significant effect on body mass, all organ masses detected. However, aldicarb treatment suppressed total antioxidant capacity in liver but not in kidneys. In summary, aldicarb treatment did not affect immune function, but suppressed liver antioxidant capacity in Kunming mice.

“…Antibody response against SRBC, as an indicator for routine evaluation of humoral immunity, involves both B and T lymphocytes and are used in immunological studies (Hõrak et al, 2003). Oxidative stress directly induces immune system damage (Biller-Takahashi et al, 2015;Marri and Richner, 2015). Hence it is likely that high ambient temperature initiated oxidative stress resulting in lower antibody titer against SRBC and Newcastle virus; however, supplemented broiler diets with 600 mg kg −1 of PHE enhanced serum antibody.…”

Abstract. Due to negative effects of high ambient temperature, the present study was conducted to investigate the effects of Portulaca oleracea hydroextract (PHE) and zinc (Zn) on the growth performance and immunity of broiler chickens reared under high summer ambient temperature conditions. A total of 420 day-old male broiler chickens (Ross 308) were randomly allocated to seven dietary treatments each replicated four times with 15 birds per replicate. The basal diet as the control diet was supplemented with 100 mg kg −1 butylated hydroxytoluene (BHT), or 300 and 600 mg kg −1 of PHE, 100 mg kg −1 of zinc and 100 mg kg −1 of zinc plus 300 or 600 mg kg −1 of PHE (ZP300 and ZP600). The result of the present study showed that Zn, PHE and their combination did not alter daily feed intake and feed conversion ratio. Although there was a tendency toward an increase in broiler body weight at 24 and 44 days of age (P = 0.059 and P = 0.061), the body weight of birds fed the basal diet supplemented with Zn reduced at day 10. The birds fed diets supplemented with BHT or ZP600 showed lower aspartate aminotransferase (ASAT) and lactate dehydrogenase activity at 24 days of age (P < 0.05), but it remains lower in the ZP600 group only for ASAT activity level at day 44. The results of the present study suggest that dietary PHE and Zn supplementation partially improved body weight and serum antioxidant capacity, superoxide dismutase activity and antibody titer against sheep red blood cells and Newcastle diseases in the broiler chickens during summer conditions.
