Physiological Reaction of Erythrocytes’ Micro Rheological Peculiarities in Milk Fed Piglets after the Negative Impact of the Environment

Abstract

One of physiologically significant and vulnerable stages of productive animals’ (including pigs) ontogenesis is the phase of milk feeding. Microcirculation is very significant for the common functional welfare of a body. It is mostly determined by erythrocytes’ state. The aim of research: to determine the state of erythrocytes’ micro rheological peculiarities in milk fed piglets after the impact of the negative environmental factor – super cooling. We examined 59 milk fed piglets of the breed “Large-White” after the impact of the unfavorable environmental factor (super cooling). In the result, 32 animals had arthritis, 27 – bronchitis. Control group was composed of 32 healthy milk fed piglets. In our study we applied biochemical, hematological and statistical methods of investigation. We found similar intensity increase of lipids’ peroxidation in blood plasma and erythrocytes of piglets after the unfavorable environmental impact which took place in the result of comparable weakening of their antioxidant protectability. Milk fed piglets with arthritis or bronchitis were found to have worsening of erythrocytes’ micro rheological features of similar evidence: comparable quantity rise of their reversibly changed (approximately on 60%) and irreversibly changed forms (nearly in 2 times) and strengthening of erythrocytes’ ability to aggregation (increase of aggregates’ number on more than 29.0%). In case of the impact of super cooling on milk fed piglets, regardless of developing later arthritis or bronchitis, we noticed similar activation of lipids’ peroxidation at comparable weakening of antioxidant protectability of plasma and erythrocytes. It was accompanied by comparable quantity rise of erythrocytes’ changed forms in their blood and comparable growth of their ability to aggregation.
