Treatments were a control diet (C1: without added oil and emulsifier), control diet added with 2% soybean oil (C2...

Cryopreservation induces oxidative stress on sperm due to an increase in the number of reactive oxygen species (ROS), thereby resulting decreased quality. ROS's destructive potential is normally counteracted by their innate antioxidant system consisting enzymes, which include superoxide dismutase (SOD). This study aimed assess quality semen from Itik Pinas-Khaki (IP-Khaki) drakes that were cryo...
