“…Similar results were obtained by Johanson et al (1988), who used cooled semen stored for four days and with different diluents, and obtained the following results: 10.7 (Betsvill), 10.5 (Modified) and 9.4 (MR-A). Contrary to expectations, Fitzgerald et al (2008) and Dimitrov et al (2007) obtained a lower number of piglets per litter after intrauterine insemination: 8.97±0.54 and 8.88±0.41, respectively. Using Duragen diluent, Berg et al (2014) obtained a high number of liveborn piglets (14.2±0.7) with cooled semen stored for 10 days.…”

“…Experimental sows underwent intrauterine insemination with a dose of 90 ml containing 1x10 9 spermatozoa. Application of even smaller semen doses was described by Weberski et al (1994), Kuster and Althouse (1999), Martinez et al (2001), Watson and Behan, (2002), Dimitrov et al (2007), Fitzgerald et al (2008), and Pelland et al (2008), while Kruger and Rath (2000) used a very low number of spermatozoa in each dose (1x10 6 / ml). Similar results on the fertility of semen were obtained by Estienne et al (2007) when nine different semen extenders were used (Beltsvill Thawing Solution, Merck III, Androhep-lite, Sperm Aid, MR-A, Modena, X-Cell, VSP, Vital) in a dose of 35x10 6 spermatozoa/ml stored at 18°C for seven days.…”

Introduction. Artificial insemination of sows with cooled semen has become a routine practice in the swine industry and has almost completely ruled out natural mating. The storage time of the cooled semen and preservation of its qualitative parameters are of the upmost importance and depend partly on the semen extender used. The aim of this study was to determine the quality of cooled semen during storage in a thermobox with a commercial extender by assessment of sperm motility, cytomorphology, and assessment of reproductive parameters in sows after intrauterine insemination. Materials and Methods. The semen was preserved with Duragen® (Magapor, Spain) extender and stored at 17±1°C. A total of 110 sows were included in the study and randomly divided into four groups: K1 (n=25) , K2 (n=25), K3 (n=30), and K4 (n=30). The sows were inseminated twice with semen (>1x10 7 /ml spermatozoa) which had been stored for 1 day (S1), 3 days (S3), 5 days (S5), or 7 days (S7). Pregnancy was diagnosed by imaging ultrasound. Results and Conclusions. The best results were obtained when the sows were inseminated with semen stored for one day. However, there were no statistically significant differences in the number and vitality of newborn piglets when semen stored for 3 or 5 days was used. Intrauterine insemination resulted in a satisfactory number of farrowings and piglets despite the fact that a relatively low number of spermatozoa was determined in each dose used. The use of semen with a higher dilution rate and its intrauterine application ensured a larger number of obtained doses from one ejaculate and indicates this would lead to a more profitable use of boars.

“…Although this technology is already established, there is a constant need to improve the reproductive zootechnical results of herds when using this procedure [2]. The demand for new researches and alternative products to improve the quality of swine semen and to decrease costs [3] is growing in middle-and large-sized swine farms worldwide [4].…”

Aims: this study sought to assess the reproductive performance of sows inseminated with sperm treated with homeopathic medicines. Materials and methods: the semen of 2 sexually mature boars age 18 months Pietrain and Duroc cross-bred with similar genetic and reproductive performance were chosen, as well as 125 sows. Sixteen samples of semen were collected and standardized through semen evaluation. Three homeopathic preparations and a placebo (control) were tested on the sperm (n=31/32 per group): Avena sativa 6cH, Pulsatilla nigricans 6cH and Avena sativa 6cH + Pulsatilla nigricans 6cH. Sows were inseminated 3 times with the same estrous diagnostic procedures. Results: there was significant difference (p
