Weaned calves are the major product from beef cows, and calves live weight is a very important factor that estimate cash prise. Milk from a lactating beef cow furnishes only about 50 % of the nutrients that a 3-4 month-old calf needs for maximum growth. If the nutrient requirements for calves are greater than the nutrients supplied by milk and pasture, the growth rate of calves will be restricted. The aim of the research was to explain creep feeding importance during grazing period. The research was carried out in the beef cattle farm “Valti” during 2014 and 2015 year for 79 days. Significant greatest daily gain in creep feeding period achieved calves from the research group – 600 g. It was established that factors sex and season affected calves growth rate. Greater daily gain in research period achieved research group bulls – 810 g. In summer-born calves creep feeding gave the positive effect and provided average about 194 g largest daily gain, compare to calves whom non-received creep feeding.
