On the bases of two characteristics correlated to immunological reactivity in the host: skin reaction to phytohemagglutinin (PHA) and serum total protein content (TP), the immunological phenoclass of cows on Tori dairy farm was determined. The relationship between cow's immunological phenoclass and productivity and fertility was assessed. The influence of age and reproductive cycle to PHA reactivity in cattle was analyzed
