The Suinfort<sup>®</sup> Semen Supplement Counters Seasonal Infertility in Iberian Sows

Suinfort<sup>®</sup>, a commercial semen supplement demonstrated to increase fertility and litter size in commercial sows, was tested to improve reproductive performance in Iberian sows. A total of 1430 Iberian sows were artificially inseminated (AI) with semen from Duroc boars and assig...

A total of 1430 Iberian sows were artificially inseminated (AI) with semen from Duroc boars and assigned by parity to receive the seminal additive Suinfort<sup>®</sup> containing 2 IU oxytocin, 5 µg lecirelin, and 2 mM caffeine (SF; <i>n</i> = 1713 AI), or to serve as non-supplemented controls (CON; <i>n</i> = 2625 AI). CON showed a lower fertility comparing to winter for spring (<i>p</i> = 0.001) and summer (<i>p</i> < 0.001); summer was lower than autumn (<i>p</i> = 0.012). SF removed this seasonal effect (<i>p</i> > 0.05). Fertility was significantly higher for SF sows during summer (<i>p</i> = 0.025) and autumn (<i>p</i> = 0.004). Total born, live-born, stillborn, and mummified piglets did not differ between CON and SF but were impacted by the season, with total and live-born decreasing in summer compared with autumn (<i>p</i> < 0.001) and winter (<i>p</i> = 0.005). In conclusion, seminal supplementation with Suinfort<sup>®</sup> improved the fertility of Iberian sows during periods of seasonal infertility.Javier PiñánFelipe Martinez-PastorBeatriz AlegreMagdalena MajRoy N.
