Purpose: The study proved automatic feeding to be more suitable for farms with large number of calves as it could substantially reduce working hours. Design/methodology/approach: The experiment comprised 20 calves which were monitored from birth until the age of 10 weeks. On specific days (1st, 8th, 29th, 50th and 71st) calves were weighed and their height of wither, height of rump and body length were measured. Findings: The comparison between feeding using bucket teat or automatic feeding system showed significant differences (p < 0.05) in the body weight during the period between 50th and 71st day of age (13.30 kg and 9.90 kg), in height of wither in the period between 8th and 29th day of age (1.80 cm and 2.70 cm) and in height of rump in the period between 29th and 50th day of age (1.70 cm and 2.70 cm). Research limitations/implications: On the first farm “A”, calves of Simmental breed were fed with milk replacer using a bucket teat (conventional feeding). On the second farm “B” calves of Holstein-Friesian breed were given milk replacer using an automatic milk feeding. Practical implications: The aim of our study was to find out which feeding strategy is more suitable for the calves and for the farmer. Originality/value: We studied different feeding strategies for calves on two farms. Significant differences were (p ≤ 0.001) in body length during the period between 50th and 71st day of age (2.80 cm and 1.50 cm).
