After harvesting of its roots, sugar beetleaves (SBL) become waste in the field. SBL could cause some inflammation problems in the digestive tract of cattle anddecrease tasty of feed. This study was carried out to determine the effects of three different extracts from SBL on hematologicaland blood serum biochemical parameters, and semen quality of goldfish Carassius auratus. These extracts contained proteins,essential oils and carbohydrates from SBL were added to fish feed at ratios of 5 and 20 ‰. The serum total protein, glucoseand albumin values increased while cholesterol and liver enzymes activities decreased in all SBL extract groups. Also, thehighest hemoglobin values were found in the groups fed with the supplementations of the essential oils extract. Moreover, thelowest lipid peroxidation and the highest catalase activity levels of seminal plasma were found in these groups. Thesupplementations of the essential oils extract which contains phytol and vitamin E improved blood parameters and increasedthe motility parameters as well.eninfo:eu-repo/semantics/openAccessBiyolojiBalıkçılıkZoolojiArticle15445846810.22392/actaquatr.556299368569
