Abstract

A survey was conducted in Sahelian and Sudanian agroecological zones to assess the biometric features of the native Fulani sheep breed. 309 adult Fulani sheep individuals were sampled in the dominant pastoral production system. Seventeen (17) body measurements were recorded using the tape measure: Height at withers at (HW), Rump height (RH), Chest circumference (CC), chest depth (CD), body length (BL), total body length (TBL), rump length (RL), rump width (RW), neck length (NL), head length (HL), head width (HW), ear length (EL), tail length (TL), barrel circumference (BC), testicle length (TesL), testicle circumference (TesC) and body weight (BW). Based on these body measurements, eleven (11) biometric indexes were calculated (sternal slenderness index, auriculo-thoracic index, format index, compactness index, massiveness index, slenderness index, frame index, dactylo-thoracic index, body index, caudal index, and auricular index). Phenotypic dimorphism (P˂0.05) was observed in the Fulani sheep population. High, long and heavy sheep were recorded in the Sudanian zone (WH= ​​81.17±4.88; BL = 73.78±6.78 and BW = 39.28±3.03). A high correlation was obtained between BW and WH (r=0.95). The principal component analysis revealed that 5 components contribute to 70.94% of the phenotypic variability observed within the Fulani sheep population. The two components explain 48.36% of the variability observed according to body measurements. As well as the WH and RH could be considered for a program of selection and conservation of Fulani sheep
