Abstract excerpt
The overall goal of this study was to reveal the genetic basis of semen production and quality traits in Italian Brown Swiss dairy cattle. Data consisted of 15,037 ejaculates from a total of 1,591 bulls. Semen traits evaluated were volume, concentration, number of spermatozoa, total motility, and progressive motility. A subset of 1,102 bulls also had records for sire conception rate, as a measure of reproductive...
