ABSTRACT
Sixty Holstein newborn calves, which were immediately after parturition separated from their dams and placed in individual pens, were randomly assigned to 4 treatment groups (15 calves per group). All calves were bottle-fed twice a day during the first 48 hours after partus, with their mothers' colostrum in 12 hour intervals, starting two hours after partus, according to the following model: i) group 1 (G1) received 0.75 L of colostrum (C) per meal, with 20 mL of 25% zeolite (clinoptilolite) suspension in distilled water; ii) group 2 (G2) received 1.5L of C per meal, with 20 mL of 25% zeolite suspension in distilled water; iii) group 3 (G3) received 0.75 L of C per meal, and iv) group 4 (G4) received 1.5 L of C per meal. Blood serum immunoglobulin G (IgG) concentrations at 0h (before C ingestion) 6h, 24h and 48h after partus and colostrum IgG concentrations were determined using commercial sRID plates (INEP, Zemun, Serbia). Apparent efficiency of absorption (AEA%) was calculated for individual calves at 6h after partus. Calf blood serum IgG concentrations at all investigated time intervals in G1 were increased compared to G3, with a significant increase at 6h after partus (15±4:10±5 g/L, p
