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 s
tud 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.
