This study was conducted to determine whether the growth rate as a response to the growth hormone concentration is a mean of predicting the performance of subsequent growth and reproductive traits in Egyptian Baladi calves. For this purpose, thirty-one calves (16 males and 15 females), were used in this study. The calves of the same sex (male or female) were divided into three groups according to their average daily gain (ADG) from birth to the ninetieth day of age associated with growth hormone (GH) level as follows:  low group (L), which recorded less than 500 and 350 g ADG with less than 18 and 15 ng/ml GH concentration for male and female calves, respectively. Moderate group (M), was recorded 500-650 and 350-550 g ADG with 18-20 and 15-17 ng/ml GH concentration for male and female calves, respectively. High group (H), which recorded more than 650 and 550 g ADG with more than 20 and 17 ng/ml GH concentration for male and female calves, respectively. Results showed that high group (H) achieved the highest values of ADG associated with the highest levels of serum GH, followed by the moderate group (M), while the low group (L) recorded the lowest values in all ages (from 6 to 18 month of age). Also, the body dimensions (body length, width at hips, height at withers and heart girth) followed the same trend of body weight and ADG. There were significant (P < 0.01) differences regarding DM, TDN and CP conversion in some months of age either in male or female calves. The high group that appeared an increase in ADG and GH levels had the highest values of serum protein profile, glucose and cholesterol values followed by the M group, while the L group recorded the lowest values. Heifers in the H group seemed superior in most of the reproductive traits compared to other groups. It could be concluded that using data of GH concentration associated with ADG from birth to the ninetieth day of age may be a useful aid in selecting strategies for improving growth efficiency and reproductive performance.
