Objectives of the present study were to estimate prevalence of failure of passive transfer of immunoglobulins in dairy calves in Northern Greece and to investigate factors potentially associated with it. Four hundred and thirty seven clinically healthy calves in 30 farms were included in the study. Age of calves was 18 h to 7 d. Animals were blood sampled and serum total protein concentrations were measured by a refractometer. Two thresholds of total protein concentration were used: 5.2 or 5.5 g dL 1. At calf level, an animal was considered to have failure of passive transfer of immunoblobulins when total protein concentrations were lower than the above thresholds. At herd level, a herd was considered to have failure of passive transfer of immunoglobulins when >20% of sampled calves had total protein concentration was <5.2 or <5.5 g dL-1.Moreover, data on health management on the farm were collected in a purpose-built questionnaire. At 5.2 g dL-1, 20% of the calves and 40% of the herds were considered to have failure of passive transfer of immunoglobulins; when the 5.5 g dL-1 threshold was used, respective prevalences were 26% and 53%. At herd level, mean blood serum total protein concentration tended to be positively affected by a short interval between birth and first colostrum meal, by maintenance of a stock of frozen colostrum and by establishment of a close-up group of dry cows. At calf level, the same factors had a statistically  significant positive effect on blood serum total protein concentration. Moreover, quantity of colostrum received by calves and colostrum condition were also positively related with blood serum total protein concentration. In conclusion, failure of passive transfer of immunoglobulins is a common problem in Holstein calves in Northern Greece. Increased prevalence of the problem implies that increased efforts and management practices need to be applied to ensure the adequate transferof maternal immunoglobulins to newborn calves. Also, it becomes obvious from all the above findings that many farmersare not well informed for management practices that have to implement to ensure adequate amounts of immunoglobulins tonewborn calves. Hence, dissemination of knowledge concerning best management practices for achieving adequate passiveimmunity is considered to be of significant importance.

The objective of this study was to investigate the effect of three methods of oral selenium-enriched yeast (Se-yeast) supplementation on the blood characteristics and growth of Holstein dairy calves. The three methods were: (1) maternal (dams supplemented with 0.3 mg Se per kg of dietary DM during 3 weeks pre-calving), (2) post-calving (calf starter enriched with 0.3 mg Se per kg of DM), and (3) maternal and post-calving Se-yeast supplementation. These three methods were compared with a control group (no supplementation). Maternal supplementation with Se-yeast successfully increased Se concentration in the colostrum and the serum of calves 24 h after calving (P &lt; 0.05). At day 56, the Se concentration in the blood of calves supplemented with Se-yeast pre- (maternal) or post-calving (via starter) was greater than the control group (P &lt; 0.05), but maternal plus post-calving supplementation was not more effective than either maternal or post-calving supplementation. Globulin and total protein concentration in the blood of calves at day 0 increased and albumins:globulins decreased with maternal supplementation (P &lt; 0.05), but these variables were similar for all treatments at day 56. Immunoglobulins in the blood of calves and colostrum were not affected by maternal Se-yeast supplementation. Maternal supplementation increased the concentration of urea in the blood of calves at 0 days (P &lt; 0.05), but not at 56 days. Calf birthweight was increased with maternal supplementation of Se-yeast (P &lt; 0.01), but growth to day 56 was not affected by the methods of Se supplementation. Maternal supplementation with Se-yeast may improve growth and health characteristics of calves at calving time.
