The aim was to monitor the growth process from birth to weaning (six months old) of the females and males Limousine calves maintained on pasture or free stabulation. The research was performed in a private farm situated in Covasna County. In this farm, the rearing of the calves was done without there being a technological guide. The calves had been grown along with the mother cows. The introduction of vegetal food into the calves ration is done at 3 weeks old. In the first period (one month old), all calves were housed in stabulation, having free access to the paddock. The daily gain was 666.7 g at females and 800 g at males. In the second period (from one month old until weaning), a group was maintained on pasture, and the other group in free stabulation. The daily gain was 1120 g at females and 1200 g at males on pasture; 1067 g and respectively 1140 g in stabulation. The stress of weaning was present only to the young females; for ten days, these were restlessness, having the desire for sucking and the appetite for food has decreased. Their bodyweight has decreased with 12%, the differences being significant (p≤0.05).
