Various natural antioxidants are being added to the freezing diluents in order to minimize deleteriouseffects to the membrane of spermatozoa during the cryopreservation process. Avaliou if stallions semencharacteristics cryopreserved amid thinner Botu-crio plus ethanol extract from the bark of mufumbo(Combretum leprosum) at different concentrations (30 mg, 60 mg and 120 mg). Samples of each treatment weresubmitted to hypoosmotic test membrane integrity tests and mitochondrial function (fluorescent tubes); Therewas no significant difference (P > 0.05) and the percentage of spermatozoa reactive to hiposmotic test betweenthe groups tested. The percentage of sperm with intact plasma membrane, as well as the mitochondrial potentialwere not statistically different (P > 0.05) between the control and treatment.(AU)
