The objective of the study was to determine the effects of dietary supplementation with N-carbamylglutamate (NCG) or NCG in combination with vitamin C on the gestation and lactation of sows under heat stress during summer. The experiment lasted 51 days from the last month of gestation to weaning (Day 21 of lactation) and involved 100 Yorkshire sows, divided into four groups, fed as follows: (1) Control diet, (2) Control diet plus 0.05% NCG, (3) Control diet plus 0.05% vitamin C, and (4) Control diet plus 0.05% NCG and 0.05% vitamin C. The reproductive performances and partial serum indicators of sows were measured. The results indicated that either NCG or vitamin C administration can ameliorate heat stress and improve the reproductive performance of sows during summer. When administering NCG and vitamin C, litter weights (16.12/13.86 kg, P < 0.05) and average weights of living piglets (1.56/1.34 kg, P < 0.05), rather than numbers born alive (10.47/10.30 head, P > 0.05), were greatly increased at farrowing, and subsequently litter weights (59.69/48.61 kg, P < 0.05) and average weights of living piglets (6.00/5.16 kg, P < 0.05) at weaning were greatly increased in comparison with Controls. The combinational additives can decrease malonaldehyde and cortisol levels, and enhance immunoglobulin G level in the maternal circulation, as well as decrease the respiration rate and increase feed intake of sows. The results demonstrate that NCG in combination with vitamin C can enhance piglet weight rather than number during gestation and lactation and has important implications for anti-heat stress during summer.

This study investigated the effect of feeding vitamin E, vitamin C, and two sources of vegetable oil on immune response and meat quality of broilers. A total of 320 one-day-old chicks were used in a completely randomised design with eight treatments arranged as a 2 × 2 × 2 factorial with two levels of vitamin E (0 and 200 mg/kg), two levels of vitamin C (0 and 1000 mg/kg), and two sources of vegetable oil (soybean and canola). Dietary supplementation of either vitamin E or C increased (P < 0.05) secondary humoral response, whereas oil sources had no significant effect. Broilers fed soybean oil had lower cellular response to the phytohemagglutinin skin test than those fed canola oil in diet, and supplementation of vitamin E increased cellular immune response. However, fat, cholesterol and pH of meat were not affected by source of oil or antioxidants, lipid oxidation was higher (P < 0.05) in thigh and breast meat of broilers fed soybean oil than canola oil. Dietary supplementation of vitamin E decreased (P < 0.05) lipid oxidation in thigh and breast of broilers fed diet containing soybean oil, without any effect on meat oxidation of those fed canola oil. Dietary supplementation of vitamin C increased lipid oxidation in thigh meat of broilers (P < 0.05). It can be concluded that inclusion of soybean oil to the diet, compared with canola oil, increased need for antioxidant. Vitamin E had beneficial effects on immune response and reduced meat lipid oxidation; nonetheless future studies should explore the antioxidant effect of vitamin C in stored meat.

Our aim was to analyse the influence of variegate porphyria (VP) on the antioxidant defenses and markers of oxidative damage and inflammation in plasma and neutrophils and the effects of dietary supplementation with vitamins E and C on these parameters in plasma, neutrophils and erythrocytes. Twelve women affected by VP and twelve pair-matched healthy control women participated in a double-blind crossover study. Each participant took 50 mg/d of vitamin E and 150 mg/d of vitamin C, or a placebo, for 6 months, by consuming an almond-based beverage as the vehicle. Women affected by VP presented higher C-reactive protein and malondialdehyde (MDA) circulating levels. Plasma antioxidant defenses were not different between porphyric and control women. Neutrophils from VP women presented decreased catalase (CAT) and glutathione reductase (GR) activities together with increased protein carbonyl levels. Reactive oxygen species (ROS) production from stimulated neutrophils was also higher in porphyric women than their controls. Dietary supplementation was effective in increasing α-tocopherol levels in neutrophils and in reducing MDA levels in plasma. Erythrocyte CAT and GR activities were enhanced by the enriched beverage only in the control subjects. In conclusion, women affected by VP present a situation of inflammation, plasma oxidative damage and neutrophils more primed to the oxidative burst, with decreased antioxidant activities and increased ROS production capabilities and protein oxidative damage. Dietary supplementation with vitamin E (50 mg/d) and vitamin C (150 mg/d) for 6 months decreased plasma oxidative damage and enhanced the erythrocyte activities of CAT and GR.
