Abstract

The purpose of this subject was the determination of the activity of glutamic pyruvic transaminase, using a colorimetric method to permit to establish standards of activity of glutamic pyruvic transaminaso in spermatozoa for study of their metabolic behaviour in different physiological and experimental conditions.Thus, the activity of GPT was determined in forty samples of semen from eight Mantiqueira bulls. The results showed that the method employed had good reproductibility and the variation coefficients wfthin of the normal limits. It was conclued that this method may be recommended for the establishment of the enzimatic standard in spermatozoa of bulls.
