Impact of selected antioxidant vitamins (Vitamin A, E and C) and micro minerals (Zn, Se) on the antioxidant status and performance under high environmental temperature in poultry. A review

SummaryStudy aim: The purpose of this study was to compare intake of antioxidant vitamins (A, C, E) in young women with various levels of physical activity.Material and methods: The study included 3 groups of females: 40 women with no extra physical activity (Sedentary), 40 women involved in regular, moderate sports activities (Recreationally Active) and 40 female athletes competing at an international level (Athletes). Participants’ diet was assessed on the basis of 3-day diet records which were analysed using the computer program ‘Dieta 5.0’. Body composition was evaluated by the bioelectrical impedance analysis (BIA) method.Results: Athletes were characterized by the lowest body fat and highest lean body mass in comparison with the other groups. They also showed the highest intake of energy, proteins and carbohydrates compared to Active and Sedentary women. The consumption of vitamin A amounted to 180.0% of RDA in Athletes, 98.8% in Recreationally Active and 97.8% in Sedentary women. Vitamin C intake in Athletes equalled 275.0% of RDA, whereas the deficiency of this vitamin was observed in Recreationally Active and Sedentary women (62.3% and 46.1% of RDA, respectively). The study groups showed consumption of vitamin E at the level of 146.7% of AI in Athletes, 115.0% in Recreationally Active and 111.3% in Sedentary women.Conclusion: Athletes consumed excessive amounts of antioxidant vitamins. Recreationally Active and Sedentary women met the demand for vitamin A and E, but the intake of vitamin C was not sufficient, which could lead to health problems. The current findings also indicate that energy intake was at a low level regardless of the study group.

AbstractTo investigate the effects of environmental temperature and dietary Zn on egg production performance, egg quality and antioxidant status, as well as expression of heat-shock proteins (HSP) in tissues, of laying broiler breeders, we used a completely randomised design with a 2×3 factorial arrangement of treatments. The two environmental temperatures were normal (21±1°C, NT) and high (32±1°C, HT). The three dietary Zn sources were a Zn-unsupplemented basal diet (CON), and the basal diet supplemented with 110 mg Zn/kg as either the inorganic Zn sulphate (iZn) or the organic Zn proteinate with a moderate chelation strength (oZn). HT decreased (P<0·002) egg weight, laying rate, eggshell strength, thickness and weight, but increased (P≤0·05) rectal temperature, broken egg rate, misshapen egg rate, feed:egg ratio, Cu Zn superoxide dismutase activities in liver and pancreas, as well as metallothionein (MT) level in pancreas, andHSP70mRNA levels in liver and pancreas of laying broiler breeders. Broiler breeders fed the oZn diet had higher (P<0·04) Zn content in the liver, as well as MT levels in the liver and pancreas, compared with those fed the CON diet. Under HT, broiler breeders fed the oZn diet had higher (P<0·05) Zn content in the pancreas compared with those fed the iZn and CON diets. The results from this study indicated that HT impaired egg production performance and eggshell quality possibly because of the disturbed redox balance andHSPhomoeostasis, whereas the oZn is more available than the iZn for pancreatic Zn of heat-stressed laying broiler breeders.

In recent decades, interest in the study of the content of fat-soluble antioxidant vitamins among residents of the northern territories of Russia has not weakened, which is associated with the transformation of the diet in a harsh climate, a negative ecological situation resulting from the technogenic pollution of the biosphere with various toxicants, and urbanization of the environment. In recent decades, interest in the study of fat-soluble antioxidant vitamins among residents of the northern territories of Russia has not weakened, which is due to the transformation of the diet in a harsh climate, a negative environmental situation that arose as a result of technogenic pollution of the biosphere with various toxicants. Аim. Conduct a comparative analysis of the content vitamins A, D, E in indigenous and alien populations, living on the territory of the Yamalo-Nenets Autonomous Okrug. Material and methods. The study involved 185 males of working age (31.3 ± 12.2 years), permanently residing in the territory of the Yamalo-Nenets Autonomous Okrug. The study participants were divided into 2 groups: the control group (97 representatives of the newcomer population) and the main group (88 people from the ethnic population: Nenets, Khanty). In all examined individuals, vitamins A and E were determined in the blood by the fluorometric method, and the concentration of hydroxyvitamin D – 25 (OH) D3 was determined using the chemiluminescent method. Results. In the course of a comparative analysis of the content of the studied vitamins in the blood, it was found that the average values of vitamin A in the newcomer population were in the range of optimal values, while the provision with vitamins D and E was 1.4 and 1.1 times lower than the minimum. permissible physiological values, respectively. The opposite picture was observed in the aboriginal population, who had a pronounced deficiency of only vitamin A. Conclusion. The results obtained indicate the presence of intergroup features in the content of fat-soluble vitamins in the body of the population of the Far North, which requires a corresponding correction of the diet and the development of a set of preventive measures aimed at improving the ecology of the environment.
