Thirty six calves were monitored from birth through to the age of 24 weeks. The Ig content of their dam’s colostrum was measured via a colostrometer and indirectly by measuring the enzyme activity of the gamma-glutamyl transferase (GGT) or the concentration of total-serum protein (TSP) in the calves’ sera during their first week of life. The concentration of albumin (Alb) and leukocyte count (WBC) in calf serum were also measured. The health status and chest girths of the calves were also regularly recorded. The mean chest girths of the ill and healthy calves did not differ significantly. The Ig concentration in the colostrum had a statistically significant influence on the TSP and GGT but not on the Alb and WBC. The interval between birth and the first intake of colostrum had a statistically significant influence on GGT and WBC, but not on the TSP and Alb. In the calves that fell ill the only statistically significant influence their illness had was on WBC. The correlation between the Ig concentration in colostrum and TSP and GGT
