title: [Effect of quality markers of ejaculates of beagle dogs after frequent semen collection].
abstract: Semen was collected from 4 adult beagle-dogs twice weekly during six months. The libido did not alter and frequent semen collection did not deteriorate the investigated parameters. Because of a bad constitution, the semen quality of one male was not sufficient. The mean volume of the second fraction of the remainder slightly decreased from January until June from 1.2 to 0.5 ml. On the contrary the mean volume of the first and third fraction increased, mainly from April until May from 0.3 to 1.0 (first fraction) and from 1.0 ml to 5.0 ml (third fraction), resp. The average of the sperm number/microliter augmented from month to month from 71.3 to 324.4 x 10(3)/microliter. The transmigration rate reached its maximum in April (52.2%). The monthly average number of the percentage of morphologically abnormal spermatozoa correlated with the corresponding transmigration rate. There were negative, linear relationships between specific morphological abnormalities of spermatozoa and both estimated motility and transmigration rate.
