Influenza di alcuni parametri quali-quantitativi del seme di verro sulla fertilità suina

176 semen samples were collected from 51 boars. Collections were made twice weekly for 6 weeks, from the and of May to July. The semen was used to inseminate 701 sows. Sperm concentration was estimated photometrically and using a counting chamber, and sperm motility by a computer-based system. Photometric determinations tended to underestimate sperm concentration. Farrowing rate was significantly affected by sperm forward motility and sperm concentration.
