This study had been carried out to investigate the effect of inbreeding on some morphological traits in purebred Syrian Arabian foals. Data of 10 body measurements for 108 horses included 60 colts and 48 fillies were collected at Bassel Al-Assad stud for purebred Arabian horses. It consisted of wither height, croup height, complete body length, back line length, chest depth, chest width, chest girth, neck girth, croup width, and cannon bone length for front legs. Pedigree data were extracted from stud book of purebred Syrian Arabian horses with four ancestor generations and Inbreeding coefficients were estimated. General linear model (GLM) was used to study the effect of inbreeding on studied traits. The results cleared that growth rate for biometric traits in Syrian Arabian foals similar to other Arabian foals in different regions. On other hand, it was different from growth rate of foals of other breeds.
