| Summary: | A number of scientific studies have established that during the farrow period sows are particularly sensitive to the action of various stress factors, including housing conditions, which lead to a violation of the activity of the antioxidant status system in their body and the occurrence of oxidative stress. Therefore, maintaining the optimal parameters of the microclimate in the premises where animals are kept during this period is important factor of the proper course of metabolism in the body of sows, fetuses and in the entire farrow process.
The article presents the results of experimental studies on the influence of such microclimate parameters as temperature, air humidity and the level of harmful gases (methane, ammonia, hydrogen sulfide, carbon dioxide, nitrogen oxide) on the number of erythrocytes, leukocytes and hemoglobin content in the blood and the activity of transamination enzymes – alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The article also provides data on the use of Vikasol and Alkosel antioxidant additives in the main diet of farrowing sows with the aim of correcting of hematological indicators and the activity of transamination enzymes in blood serum by the violation of the microclimate parameters of the premises.
As a result of the conducted research, it was established that increased parameters of air temperature and relative humidity in the premises for keeping farrowing sows significantly reduce the number of erythrocytes, leukocytes and the hemoglobin content in the animals’ blood. The use of Vikasol supplements in the diet of sows increased the number of erythrocytes, leukocytes and the hemoglobin content by 3.7%; 8.5%; 13.8%; and the use of Alkosel – respectively by 2.4%; 22.7% and 5.07%. The combined use of both preparations increased the number of erythrocytes by 4.2%; leukocytes – by 21.1% and hemoglobin content by 29.2% compared to the control. As for transamination enzymes, the use of Vikasol reduces the activity of ALT by 10.4%, the use of Alkosel – by 18.5%. The combined use of both preparations – by 27.5%, increasing the activity of AST from 4.7% to 21.4% in relation to standards.
