The follow-up of the growth of the Ndama bovines through the barymetric formulas has feta approached with Congo Brazzaville, in the Technical Center of Support of Dihessé which aims at the multiplication and diffusion of the animals in the country medium and the repopulation of the official breeding. This study makes a development of the barymetric equations of females and males of Ndama of birth in 20 months of age. By age group, the thoracic perimeter (Pt) and the live weight (PV) have collected for 253 males and 405 females. The males are born with an average weight from 19.5±0.5 kg and females with 18.14±0.5 kg (td> 1.96). In the 16th month the live weight is not different but significant (114.5±10 kg and 90.1±5 kg). The thoracic perimeters were 62.2±6 cm and 60.7±11 cm with the birth and 110.5±3 cm and 103.8±6 cm in the 16th month (td>1.96).The coefficients of correlation enters the perimeter thoracic and the live weight is higher than 0.80 in the three phase of growth 'observed. This evaluation corresponds more to one series of segments of straight regression line. The equations of regression are relatively higher in the males than in the females (Y = 0.797 X-5.741 et Y = 1.899 X-111.918) to 10 months of age.
