DNA fragmentation index - a marker of fertility mink sperm products

The main direction of the research was to study the morphological and functional characteristics of spermatozoa in the ejaculate of male minks and to identify the fragmentation index of nuclear and mitochondrial DNA of spermatozoa.In the course of the experiment, a direct dependence of the biological usefulness of sperm on protein nutrition was established, namely, the lack of the necessary composition of amino acids in the basic diet of minks.The results of the study showed that in the ejaculate of males who received 2 and 4 ml of a 15 % solution of protein hydrolyzate in the diet, compared with the control group, who received only the basic diet, the content of motile spermatozoa is 17 and 15 % more (p
