This work focused on inexpensive methods of evaluation fowl sperm morphology, based on eosin-nigrosin smears, which can determine disorders in spermatogenesis and can be recommended for evaluating the fertilising potency and selecting males in flocks reproduced by artificial insemination. Four fowl breeds (Black Minorca, Italian Partridge, Forwerk and Greenleg Partridge) were used to determine the efficacy of sperm morphology evaluation using four eosin-nigrosin staining methods (according to Blom, Bakst and Cecil, Morisson, Jaśkowski) and three examiners of different experience (high, medium, novice). There were significant (P 0.01) differences in sperm morphology between Blom's staining method and those of Bakst and Cecil, Morisson or Jaśkowski, irrespective of fowl breed and examiners experience. Blom stain caused sperm head swelling and showed a drastic reduction in the proportion of live spermatozoa with normal morphology. The staining method had a greater influence on sperm morphology evaluation than the experience of the examiners.
