Effect of bovine seminal protein on the quality of frozen spermatozoa from goats

The aim of this study was to determine if the quality of frozen spermatozoa from goats can be improved by adding bovine seminal protein to sperm diluent. Thirty-six healthy, 3-5 years old, 40-45 kg high-libido goats were used. Seminal protein was obtained from two five-year old Simmental bulls. The 36 goats were equally distributed into three groups: P0, with only egg yolk citrate diluent and goat semen; P1, with 2.5 mg/ml bovine seminal protein, egg yolk citrate diluent and goat semen; and P2, with 5 mg/ml bovine seminal protein, egg yolk citrate diluent and goat semen. Results suggest that addition of 2.5 mg/ml bovine seminal protein to goat sperm diluent can improve the quality of frozen spermatozoa of goats.
