Abstract

The study of physical, biological and morphological parameters of sperm production, despite the strict criteria established by regulatory documents, does not always allow an objective assessment of fertility ram producers. The study of sperm production in terms of the DNA fragmentation index in addition to studies on morphological parameters will allow the most complete and objective assessment of the reproductive ability of the studied spermatozoa of ram producers. The informative value of this method of research, coupled with simplicity and low cost, allows us to recommend this study in the practice of evaluating sperm quality.
