Abstract

Currently, the pig feels the need to further clarify aspects of the physiology of pigs. It is very important to clarify the changes of functional parameters of piglets at the impact of any environmental factors. Negative environmental impact can often particularly adversely affect hemostasis. However, changes its parameters clarified weakly. Objective: to assess changes in hemostasis in piglets undergoing overheating. The research involved 42 pigs at the age of 2.5 months breed: large white, which has experienced overheating during 3 hours as a result of breakdown of air conditioning system. The control group included 32 healthy animals kept in normal conditions of a pigsty. The experienced piglets determined significant increase of platelet aggregation that occur spontaneously and in response to stimulation. Experienced pigs blood coagulation was found high and significant weakening of fibrinolysis. Apparently, the overheating affects animals’ haemorheology and significantly inhibits anabolism. It is clear that in piglets, which suffered from overheating, activated hemostatic system, which affects the microcirculation and inhibits growth. For this reason, there is a great need in the search approaches for leveling in piglets undergoing an episode of overheating, excessive activity of blood coagulation and increased platelet aggregation.
