摘要: The aim of the research was to study influence immune status on health and changing heart girth with age in calves. Seventy one dairy calves from birth 24 weeks were studied their monitored. blood samples taken once a week, till 6 later at 8, 12, 16, 20 weeks. In concentration IgG measured quantitative ELISA test. At each bleeding, measured. average 1 st week 26.15 ± 15.18 g/L. divided two groups; group there below value, 2 nd above average. Statistically significant differences between groups established (P < 0.001), = 0.044), five eight 0.017) sixteen 0.029). percentage diseased significantly higher regarding 2. girths did not differ significantly. it that level remained end period more low group.
