Influence of Organic Selenium (SelPlex) on the Reproduction on Males Carp (Cyprinus carpio), Lausitz Variety

The goal of this research was to analyze the effect of organic Selenium (SelPlex) on the reproductive function in 3 summer old males common carp (Cyprinus carpio), Lausitz variety. The researches were carried out on two groups on a total 12 males carp in 3 summers old (6 in each group). Experimental period was 39 day and organic Selenium (SelPlex) at a dose of 0.03 mg/kg feed was added in the feed for the experimental group. The use of SelPlex significantly influenced the concentration of spermatozoa of the three summers carp. Analyzing the results obtained shows that the addition of organic selenium in the nutrition of carp breeders caused a slight increase in protein, and fat decreased slightly from sperm, the differences between groups were non-significant (p>0.05%). The slight increase in the amount of protein in milt is due to the positive effect of organic selenium over glutathione peroxidase activity of sperm cores (SN-GSH-Px), which is an integral part of sperm chromatin with the possibility of amino-acid uptake. Researches regarding viability, meristically and somatic measurements of breeders were carried out and significant differences were recorded in the experimental group compared to the control
