Abstract Background One of the semen quality parameters use to determine fertility is the percentage of sperm that express normal morphology. Sperm head morphometry is also correlated with fertility. The objectives of this study were 1 to investigate the sperm morphology and normal sperm head morphometry of Thai native crossbred stallions and 2 to compare our results with the characteristics of proven fertile sperm from purebred stallions. Methods Semen samples were collected monthly from nine stallions of which five were Thai native crossbred T and four were purebred of proven fertility F F1 was a Standard-bred F2 was a Warmblood F3 and F4 were Thoroughbreds . All the animals were aged between 5 and 12 years. Sperm morphological examination was performed using formaldehyde-fixed
