The objective of this study was to evaluate the effect of addition of the antioxidants Trolox and catalase to a ram semen cryopreservation extender on lipid peroxidation and hydrogen peroxide generation on the extender and in the thawed semen. Semen was collected from 23 Santa Inês rams (one ejaculate per ram) and diluted at 32 ?C to a concentration of 400×106 cells/ml in one of the following solution: Tris-egg yolk extender (control), or the same extender supplemented with either 50M Trolox/108 sperm (Trolox), 50g catalase/ml (Catalase) or a combination of Trolox and catalase (Tro + cat, 50M Trolox/108 sperm and 50g catalase/ml). The semen was loaded into 0.25 ml straws, cooled and frozen in a programmable freezer and subsequently stored in liquid nitrogen. Prior to evaluation, frozen straws were thawed in a water bath (42? C for 20 s). Lipid peroxidation (LPO), both spontaneous and catalyzed, on the semen and the extender were measured using the thiobarbituric acid (TBA) assay in accordance with the method described by Buege and Aust (1978). Hydrogen peroxide (H2O2) generation was measured using the horseradish peroxidase-dependent oxidation of phenol red to a derivative with absorbance at 610 nm, according to the method described by Pick and Keisari (1980). Spontaneous LPO resulted in the least production of thiobarbituric acid-reactive substances (TBARS) in the Tro + cat (1.37±0.02 nMol/108 sperm), compared to amounts in the other treatments groups. In the catalyzed LPO experiments, the least (P < 0.05) amounts of TBARS were observed in Trolox (2.52±0.02 nMol/108 sperm) and Tro + cat (2.54±0.02 nMol/108 sperm) groups, compared to the control (3.81±0.02 nMol/108 sperm) and catalase (3.83±0.02 nMol/108 sperm) groups. Hydrogen peroxide generation was less (P < 0.05) in the Trolox (6.00±0.18 nMol/40×106 sperm/±40 min) and Tro + cat (6.08±0.18 nMol/40×106 sperm/±40 min) groups than in the control (6.97±0.18 nMol/40×106 sperm/±40 min) and catalase (6.53±0.18 nMol/40×106 sperm/±40 min) groups. Compared to the control group, Trolox and catalase treatment significantly reduced TBARS in catalyzed LPO and hydrogen peroxide concentrations in the samples (P < 0.05).
