The objective of this study is a morphometric characterization of local goats in western of Algeria. With the use of 19 quantitative variables, we carried out a discriminant analysis on 119 goats and 32 bucks divided into 4 Wilayas (Tlemcen, Adrar, Naama and Bechar). The discriminant analysis on males was not significant. As for the female population, the analysis of variance (ANOVA) on the region effect was highly significant p=1.32 x 10-11. A clear separation has been found between the populations, with the exception of Naama and Tlemcen, which are overlapped. Measurements belonging to chest width ( LP),chest circumference ( TP), chest depth ( PP), rump width (LB), ischium width (LI), withers height( HG), ear length LO) and hair length (LPI).are the best variables that separate between regions in the female population, with a very high significance level (p<0.01). The area under the ROC curve (AUC) is 82.04%. This study can serve as a basis for more precise genetic characterization studies of this species.

The Barbary sheep (Ammotragus lervia) is a hoofed animal ranked globally as a vulnerable species. The Tlemcenhunting reserve is one of the structures that aims to protect, preserve and develop this species in ex-situ, but theproblem is that the reserve does not have the history of its provenance; On the basis of this observation, we havehighlighted our study, which is divided into two parts. The first part focus on a morphometric study targeting 42 adultindividuals, 18 of which were imported from the United Arab Emirates and 24 developed in Algeria; this study focusedon 18 variables including 15 quantitative and 3 qualitative. The data collected were subjected to a statistical analysis bythe software R which; the principal component analysis (PCA) and the ascending hierarchical classification that the twopopulations are distinct from each other without significant separation since the work has was conducted on the samespecies. In addition, we have been able to identify specific subjects of each population that can be used as breeders. Asfor the second part, it is a phylogenetic study targeting the population of Algeria only, in which a molecular analysis of6 collected samples has allowed us to obtain a partial DNA sequence of cytochrome b. We subsequently retrieved thenucleotide sequences of cytochrome b from the same taxonomy from the GenBank database and processed all thesequences by the MEGA software, after alignment by the ClustalW method. The phylogenetic tree showed that thebarbary sheep population of the Tlemcen hunting reserve is a North African subspecies.
