[Thawing of bovine seminal fluid].
Comparative experiments were carried out at 39 degrees C and at 70 degrees C in water bath for the thawing of seminal fluid frozen in straws. The motility of spermatozoa was followed up as well as the absolute survival rate after thawing. By means of a thermocuple the temperature rise was traced as occurring in independence on the weather. The results spoke in favour of the regime at 70 degrees C for 7 sec. They were statistically significant (p less than 0.001). At 39 degrees C motility of spermatozoa was 36.26 per cent, and the absolute value of survival rate--353.85 min. (at 70 degrees C--45.47 per cent, and 376.85 min respectively). It is suggested to use the regime at 70 degrees C in an automatic apparatus, which is now being tested by the author.
