The experiment was conducted from birth to 150 days of age with 32 calves (16 heifer and 16 bull calves), assigned to four analogous groups (8 animals: 4 ♀ and 4 ♂ per group). In group I, calves suckled colostrum (ad </p><p>libitum) and mother’s milk from 5 to 90 days of age (twice daily for 30 minutes); in group II, they suckled colostrum (ad libitum), mother’s milk from 5 to 42 days of age (twice daily for 30 minutes), and received milk from nipple buckets (6 l twice daily) from 43 to 90 days of age; in groups III and IV calves received from nipple buckets a limited amount of colostrum (4.5-6 l/day) and milk (on average 5.82 and 4.82 l/day, respectively). Feeding limited whole milk from nipple buckets to the calves did not cause significant differences in haematological blood indices, serum concentrations of glucose and IgG, and health status of calves compared to those suckling their mothers.
