Abstract
- Often, for the sows's artificial seeding, literature recommends the use of a 3-5 billion mobile sperm / dose. This number is high compared with other species and is determined by the particularities of the uterus. With various techniques has tried to reduce the number of sperm \ dose without sowing depreciate results. Intrauterine insemination consists in semen laying in the uterine horn base, using a special catheter, simple and easy to handle. Avoiding the first obstacle for the spermatozoons, cervix, the method allow the spermatozoons number (insemination dose) decrease, without sow reproduction performance depreciation. Biological material was represented by Camborough primiparous and multiparous sows distributed in tow batches: · control batch (CB) -usual inseminated sows with 4 billions/dose mobile spermatozoons; · experimental batch (EB)-intrauterine inseminated sows, with 2 billions/dose mobile spermatozoons. Semen was diluted with diluent Merck III. Each sow was inseminated twice on heat cycle. Intrauterine inseminations lead to fecundity increasing (by 6,9%). Differences between groups were semnifictive (p <0.001). In both groups, the fecundity was lowest in summer season compared to others. Prolificity increase too (0,24 piglets/sow). Differences were not significant (p <0.05). Number of piglets wean was near regardless of insemination technique. [ABSTRACT FROM AUTHOR]
