The nonspecific resistance analysis of the Ukrainian Grey cows at “Polyvanivka” breeding farm located in Magdalynivka district, Dnipropetrovsk region has been shown. The researches were conducted in winter-stall period on the animals (n=19) of two age groups — up to and over 5 years. Phagocytic activity of neutrophils, phagocytic number and index were determined in blood of the experimental cows, lisozymic and bactericidal activities — in serum. 50 % selection modelling was carried out due to phenotypic manifestation of traits of nonspecific resistance. The degree of correlation was determined between natural resistance and breeding traits.
It has been established that the investigated Ukrainian Grey cows had almost the equal level of natural resistance with a tendency to the slight increasing in the older animals. Cows of both groups had significant degree of individual variability by bactericidal activity. Reliable advantage (P<0.05) of the cows with higher phagocytic activity by 210 days live weight, daily gain from birth to weaning has been established by 50 % selection modelling. Modelling the similar groups of animals by functional activity of humoral nonspecific resistance has shown that animals with better lisozymic and bactericidal activity significantly (P<0.05) dominated cows with worse phagocytic activity and phagocytic number. There was small advantage by body weight and average daily gain (except at age of 15–18 months) but the difference was unreliable.
Correlation analysis has revealed reliable inverse relationship of humoral nonspecific factors with first calving age. Close relationship of cellular and humoral factors of nonspecific resistance has been confirmed.
