The aim of this research is the study of the animal genetic resources biodiversity and to list information on the main varieties of indigenous cattle "Brune de l'Atlas". Data collected during 2022, from 51 cows with two stage of lactations. In this context to characterize this population, sixteen body measurements and five qualitative traits were used. The morphometric approach addresses the following measurements: HG, HD, HS, HP, LSI, LE, LH, LB, TP, TCA, Ltro, Lisch, IDT, PV1, PV2, TS) and the phenotypic approach based on coat color, mucous membrane color, head color, leg color and cephalic profile. The barymetric results obtained are respectively 134.33±9.28cm, 131.51±8.50cm, 137.25±9.63cm, 70.55±5.62cm, 151.10±12.76cm, 41.94±5.48cm, 50.35±5.97cm, 9.76±4.40cm, 172.59±10.68cm, 20.25±1.26cm, 47.63±5.77cm, 30.67±4.84cm, 0.115±0.016cm, 415.86±75.06kg, 387.93±13.46kg and 212.63±13.46cm. The fawn color is the dominant color of the studied population; it is 58.8% with the presence of different colors: black, gray and light gray. The majority of the population has dark mucous membranes (64.7%) and a concavilinear cephalic profile (72.5%). In conclusion, the majority of indigenous cattle are short stature and fawn in color.
