Abstract: During 4 years, about 3378 body parts measurements were harvested for different birth mode of 149 males and 127 females of indigenous kids raised under pastoral arid conditions at some standard ages: birth, 30, 60, 90, 120 and 150 days. Data was used to establish local kid`s stature growth after the birth and till 20 weeks` age. The study focused the kinetic evolution of 17 kid`s body parts. The individual measurements underwent an extra and/or intra-polation to estimate performances. Statistical analysis was applied to establish the parameters and the variation of individual performances. The body length of male recorded in these age types were found to be 25.35±3.58, 31.41±3.60, 35.67±3.61, 40.20±4.86, 43.79±6.03 and46.10±6.67 cm wile that of female in these age groups were investigate to be24.82±3.00, 31.58±2.89, 35.17±3.38, 38.67±4.13, 41.51±5.08 and 43.18±6.22 cm, respectively. The mean height at withers in male in standard age groups were noted to be 30.55±3.09, 36.94±3.21, 41.34±3.75, 45.23±4.76, 48.46±5.34 and 51.16±5.57 cm while that of female in these age were recorded to be 29.84±3.19, 36.42±2.95, 39.65±3.20, 42.84±4.54, 46.30±5.34 and 48.44±6.35 cm, respectively. The mean heart girth in male in these standard ages was recorded to be 30.24±2.96, 36.79±4.19, 42.87±5.02, 47.34±5.47, 51.76±5.96 and 54.86±6.22 cm. Concerning female mean heart girth was noted to be 29.66±3.59, 36.57±3.96, 41.45±4.13, 45.93±5.15, 49.71±6.02 and 53.00±6.06 cm, respectively. Indeed the study consist body measurement of kids birth mode essentially (body length, height at withers and heart girth) of 149 born single and 127 born twins in the same standard age (birth, 30, 60, 90, 120 and 150 days). Average body length was 24.98±3.15, 31.84±3.09, 36.31±3.60, 40.59±4.51, 44.02±5.23 45.73±6.22 for single and 25.26±3.53, 31.07±3.47, 34.42±3.10, 38.21±4.36, 41.24±5.91, 43.62±6.90 for twins, respectively for the standard age. Also for height at withers was 30.86±3.01, 37.36±3.29, 41.82±3.55, 45.77±4.70, 48.49±5.76, 51.63±6.86 for single mode and 29.84±3.19, 36.42±2.95, 39.65±3.20, 42.84±4.54, 46.30±5.34, 48.44±6.35 for the twins mode, respectively for the same standard age. In addition the heart girth of the birth mode at this standard age was 30.38±2.86, 37.40±4.15, 43.75±4.41, 47.92±5.54, 52.32±5.97, 55.10±6.27 and 29.50±3.65, 35.85±3.85, 40.43±4.34, 45.25±4.78, 49.06±5.71, 52.72±5.90, respectively for single and twins. Pearson correlation illustrates relationships between body parts and body weight of local kids`. This correlation during growing life was higher significant (p< 0.01) for each sex and each age type especially after 30 days. Based on the magnitude of the correlation body length, height at withers and height girth could be selected for predicting live weight of the animals after one month of age.
