In the effectuated research, we aimed to observe the effect of dilution of boar sperm with water with a 30 ppm deuterium content on sows’ fecundity. The control batches (CB) were formed by 367 sows inseminated with doses based on bi-distillate water. Experimental batches (EB) were formed by 366 sows inseminated with doses based on deuteriumdepleted water. The effect of deuterium depleted water was analysed function on utilised synthetic diluent (BTS and Merck), boars’ age and season for sperm gathering. In relation with utilised diluent, fecundity was between 79.5% and 80.2% at CB and between 78.7% and 81.9% at EB. Fecundity of boars aged 1 year oscillated between 79.9% at CB and 79.8% at EB, and at boars with age of 3.5 years between 79.8% at CB and 80.8% at EB. In spring, fecundity was between 81.1% at CB and 82.2% at EB, and in summer between 78.6% at CB and 78.3% at EB. No matter of analysed factor differences between control and experimental batches were insignificant.
