“…The type of diluent, as well as the type and inclusion level of cryoprotectant, may be modified again to obtain better results (Gerzilov, 2010;Rakha et al, 2018;Di Iorio et al, 2020). Previously reported studies on rooster semen cryopreservation showed that the inclusion levels of DMSO or glycerol can vary depending on the cryopreservation procedure and the animal breed used, suggesting that a single protocol will not always work for all breeds (Blanch et al, 2014;Khaeruddin et al, 2019;Long et al, 2010;Pelaez et al, 2011;Svoradová et al, 2018;Telnoni et al, 2017). In rooster semen cryopreservation, a higher inclusion of DMSO [i.e., 7.0% (Khaeruddin et al 2019) and 10.0% DMSO (Telnoni et al, 2017)] was used.…”
