Ejaculate quality is influenced by boar behaviour at the time of collection

Ejaculates were collected from the same boars twice a week, in spring during two years. Most animals had very good sexual reflexes and were scored as 5. They gave ejaculates which had good volume, concentration and motility and could be processed into the largest number of insemination doses. This had an obvious positive economic effect. Age influenced ejaculate quality in young boars, with the exception of a few animals in which sexual reflexes were diminished. Nevertheless, ejaculates had the necessary characteristics and could be processed.
