Morphological characteristics of stallion spermatozoa.
A study of the morphological characteristics of stallion spermatozoa was conducted at the semen laboratory of the Department of Animal Production during four breeding seasons. A total of 590 ejaculates collected from 216 stallions aged from 2 to 26 years and including 13 breeds or colour types was examined. Overall means for the spermatozoal characteristics of these stallions and the classes of head and tail abnormalities are presented and compared with results of other works. Scanning electron micrographs are included to illustrate recognised abnormalities.
