The viability of production system in which the calf is an economic component is relevant for the entire production sector. This study was carried out to evaluate the growth of ae HZ calves, progenies of F1 HZ cows submitted to three milking periods and fed different roughages. Thirty F1 cows were randomly allotted to three feeding treatments: T1 ‐ Pasture plus 1.250 kg of supplement/day; T2 ‐ Pasture plus 1.250 kg of supplement/day; T3 ‐ Roughage offered in feedlot. The cows were milked daily to the end of the lactation period, except for cows of treatment T2, which were milked during 200 days of lactation. Calves were fed milk until 60 days of age and corn silage during the dry season and pastures in the rainy season. The T2 calves remained with their mothers from 200 days to the end of the lactation period. No difference (P>0.05) among treatments for calf weight gain until the 200 days of lactation was observed. After 200 days of lactation, T2 calves, remaining with their no milked mothers, showed higher weight gain (P<0.05) in comparison to calves of the other treatments. Calves allotted to the alternative system in which they remained with their no milked mother from 200 days of lactation to the end of lactation period show higher weight gain, in comparison to calves from the traditional system.
