| الوصف: | RiassuntoTraditional insemination techniques in pigs depose a high number of spermatozoa (2 to 3x109 spermatozoa) in a large volume of liquid (80-100 ml) into the cervix channel. The dose can be reduced markedly deposing it directly into the uterine horn. Previous studies showed that fertility rate and litter size were not significantly different with 5 or 15x107 spermatozoa in 10 ml into the uterus. The goal of this study was to determine the on-farm application and the reproductive performance of the deep intrauterine insemination (Firflex® probe, MAGAPOR, Spain) in sows. Experiments were conducted under field conditions in 4 commercial pig farms in the North of Italy (September 2003 and March 2004). A total of 166 crossbred multiparous sows were randomly selected after weaning and assigned to one of the following groups: Group 1 – traditional insemination with 3x109 sperm./dose, two insemination per oestrus (n=94) and Group 2 – deep intrauterine insemination with 15x107 sperm./dose, one insemination pe. |
