Extract

The mean change in the pH of 134 undiluted ejaculates of clinically normal bulls was –0·302 ± 0·027 after 1 hr. storage at 37°C. The greater the pH. change, the lower was the initial pH and the higher was the initial motility and the number of spermatozoa per c.mm. The greater the decrease in pH the poorer was the motility after incubation. The motility was better maintained in semen diluted with egg-phosphate medium, compared with undiluted semen, which agreed with the smaller pH change in this medium. There was no evidence of a relationship between the pH change and the motility after incubation and the period of time for which a high motility was maintained during storage. It is suggested that the determination of the initial pH and the pH change after 1 hr. incubation may provide a useful and accurate evaluation of the semen of the bull.
