Evaluación del efecto crioprotector de diferentes fuentes de antioxidantes en el semen bovino

Abstract

Regional Livestock Union and Autonomous University of Chihuahua - Mexico, evaluated different concentrations of antioxidants; cysteine 2mM, Caffeine 5mM, ascorbic acid 4.5 mg / ml in a commercial diluent, plus a control treatment to analyze semen quality: Viability %, Progressive motility %, membrane integrity %, acrosomal integrity %. We used 6 ejaculates of different animals, obtained by the use of an electro ejaculator. The experiment was managed under a DBCA, the results obtained were subjected to a Tukey test at a P ≥ 0.05. The data presented for the mentioned variables did not show significant statistical differences; the benefit / cost was $ 1.63 for the control treatment. Under the technical conditions and resource in that this research was carried out, the use of a source of extra antioxidants in the commercial diluent for cryopreservation of bovine semen did not improve seminal quality characteristics.
