Activity of enzymes of the antioxidant system in the blood of sows depending on the microclimate of the premises

Abstract

Goal. To investigate the activity of enzymes of the antioxidant system in the blood of farrowing sows, depending on the parameters of the microclimate of the premises and the introduction of Vikasol and Alkosel supplements into animal feed rations. Methods. Biochemical (determining the activity of enzymes of the antioxidant system: catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPO)). Sanitary and hygienic (determination of the main parameters of the microclimate of the premises). Analytical (study of literature). Statistical (variational and statistical processing of the obtained results). Results. In the course of research, it was established that in the conditions of high temperature and relative humidity in the premises for keeping farrowing sows, the animals are in a state of oxidative stress, and the addition of Vikasol and Alkosel in amounts of 6 mg and 5 mg per 1 kg of compound feed, respectively, activate enzymes of antioxidant protection in the blood. In particular, under the action of the above-mentioned additives in the blood plasma, an increase is observed in relation to the control of the activity of enzymes: superoxide dismutase (SOD) by 3.62% and 8.30%, catalase (CAT) by 2.5%, 2.04%, glutathione peroxidase (GPO ) — by 3.4% and 4.14%. It was also established that the combined use of the specified oxide protectors in the specified doses in the compound feed of sows increases the activity of superoxide dismutase in the blood of animals by 15.54%, catalase by 6.12% and glutathione peroxidase by 20.7% compared to the control. Conclusions. The conducted studies indicate that the violation of the temperature and humidity regime in the premises for keeping farrowing sows leads to the occurrence of oxidative stress in the animal’s body, and the introduction of Vikasol and Alkosel supplements into their diets has a positive effect on the activity of the enzymes of the antioxidant defense system in the blood.
