The improvement of newborns’ immunity and metabolism are the most important measures to protect the new-born calves against morbidity and to get better growth results. The study is part of the project LCS 672/2014. The aim of the study was to compare the effect of two feeding methods of new-born calves on the blood biochemical results at the age of 24 hours and on the weight gain within a 30-day period. The experiment was performed in two herds with 250 and 270 dairy cows - X and Y. In the herd X, 10 newborns received on average 2.6 litres of high quality colostrum in the first hour of life with the oesophageal probe. After that, they received milk three times per day. In the herd Y, 10 newborns received on average 2.6 litres of different quality colostrum from the bottle with a nipple within the period of 1-7 hours after birth. Later, they were fed with milk two times a day. Venous blood samples were collected 24 hours after the birth (D1). Calves were weighed on D0, D15 and D30. In the herds X and Y, the following results were obtained: the weight gain on D0- D15 was 752±165 g/day and 385±116 g/day (p=0.09), respectively; plasma total protein concentrations on D1 were 70.5±8.7g/L and 59.3±4.3g/L (p=0.02); serum GGT activities were 846.3±568.8 U/l and 131.4±41.5 U/l (p=0.01). Better results were obtained in the herd X where calves received 2.6 L of colostrum with the probe in the first hour of life, and where they received milk 3 times per day, in comparison with the herd Y.
