英文摘要	The Algerian goat herd has an extraordinary genetic diversity but till now, its populations have been narrowly described. The objective of this study is the morphological characterization of goat populations living in southeastern Algeria in perspective to develop a goat breeding strategy in the study's area. In total, 906 goats including 791 females and 115 males were phenotyped from 12 districts representing five zones of Biskra using 17 quantitative variables and 10 qualitative ones. Goats have been identified by breeding location. The results showed that the breeding site had a significant effect on some external measures and qualitative morphological traits. Strong positive correlations were observed between the majority of external measurements. PCA revealed the most discriminant characters describing size and shape of goats, namely head length (HL), body length (BL), hair length (HairL), and tail length (TL), ischium width (IW), chest circumference (ChC) and chest depth (ChD), height at withers (HG) and rump (HR), and the round of the anterior cannon (RAC). It allowed goat repartition into homogeneous groups. Three subpopulations were obtained by the clustering method. This study is the first step towards establishing programs for the conservation and improvement of local goat genetic resources threatened by uncontrolled crosses.
