Erythrocytes’ Microrheological Features of Piglets during the Phase of Dairy-vegetable Nutrition after Damage or Common Supercooling

Abstract

Notwithstanding the great successes of biology and veterinary science, possible changes of cytoarchitecture and erythrocytes’ aggregation in piglets during the phase of dairy-vegetable nutrition after unfavorable environmental impacts haven’t been studied yet. The aim of the research: to find out peculiarities of erythrocytes’ microrheological features in piglets during the phase of dairy-vegetable nutrition after damage or common supercooling. We observed piglets during the phase of dairy-vegetable nutrition after casual unfavorable environmental impact: 28 animals with arthritis after some joint damage and 23 piglets with bronchitis after common supercooling. Control group was composed of 39 healthy piglets of the same age. We estimated the activity of lipids’ peroxidation, indices of plasma and erythrocytes’ antioxidant protection, condition of cytoarchitecture and erythrocytes’ aggregation. Statistical processing was conducted by Student’s t-criterion. We found similar intensity increase of lipids’ peroxidation in blood plasma and erythrocytes of observed piglets after unfavorable impacts (about 66.7% for arthritis and about 68.9% for bronchitis) against the background of comparable weakening of their antioxidant protectability (in both groups for catalase on approximately 25.0%, for superoxide dismutase on approximately 11.0%). There was quantity increase of erythrocytes’ changed forms (reversibly changed forms on approximately 50.0%, irreversibly changed forms approximately in 2 times) in these piglets and strengthening of their spontaneous aggregation (number increase of erythrocytes’ aggregates in blood of animals in both states on more than 20.0%). In our research it was shown that piglets during the phase of dairy-vegetable nutrition after negative environmental impacts experienced worsening of erythrocytes’ microrheological features. Its evidence didn’t depend on the character of the influencing factor.
