AbstractFull Text

Semen from Large White and Pietrain boars was collected at 3 and 4 day intervals. Volume, percentages of live, immature and motile spermatozoa and tail abnormalities were evaluated in order to assess ejaculate quality. The number of insemination doses per ejaculate was calculated for each breed and ...
