Abstract
The current study present the obtained results for rearing and development of female youth sheep belonging to breeds Merinos de Suseni and Polwarth and also of the half blood obtained through crossbreeding of Ile de France males and Polwarth females. The three female youth sheep batches were weighted and measured at: birth, 3 months, 6 months, 12 months and 18 months. Based on the obtained data was calculated the mean daily gain and were appreciated the main corporal dimensions. At the end of the study we observe that the best growing rate was recorded at hybrid female youth sheep (Ile de France x Polwarth), at which the mean daily gain was higher with 9.87% face to Merinos de Suseni breed and with 20.27% face to Polwarth breed. Growing intensity of corporal dimensions is gradually decreasing from 6 months till 18 months at all three batches of studied youth sheep.

Key words: youth sheep, growing, development, half blood
