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.

Abstract
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.File in questo prodotto:
