Calf rearing is the first and in terms of the future performance of cows important stage of the breeding heifers. In the Czech Republic reached in 2014 the average replacement herd of cows in 32.5% in a group of 80 farms producing milk 31.5%. In the Czech Republic we can therefore use pregnant heifers estimated at 32, within farms then at 20 to 50 heifers per 100 cows. Foreign file achieved in the years 2009-2015 costs 7,230 CZK (2 195-9 350 CZK) for bred calf and CZK 117 (CZK 46-172) on the day of his breeding. Half of the cost was spent on feed (milk, milk substitutes, grain mixes, roughage) and 30% on labor costs. Average costs (without overhead) for rearing calves up to 6 months of age have been identified in 24 farms in 2011 in the Czech Republic reached CZK 8,987 per calf and CZK 45 per day. With regard to economic indicators, considerable attention is paid to the problems of housing, feed and consumption work in treating calves. Shortening the breeding of three weeks (from 12 to 9) resulted in a reduction in feed costs about 675 CZK and 19% and labor costs by CZK 185 and 9% of calf. Increase daily weight gain of calves per 100 g results in an increase in their future milk yield at first lactation by 155 kg of milk. Possible savings exist mainly in price and quality of feed, in the choice of rearing and housing and consumption and work organization.
