From: Oxytocin in pig seminal plasma is positively related with in vivo fertility of inseminated sows
Violin plots showing the oxytocin (OXT) concentration measured in seminal plasma (SP) samples from entire ejaculates (n = 61) collected from boars of different breeds (Duroc, n = 14; Pietrain, n = 18; Landrace, n = 15; Large White, n = 14) used as semen donors in artificial insemination programs. Each dot indicates SP-OXT concentration of each individual ejaculate, dashed lines the median and dotted lines the 25th and 75th percentiles. No differences (P > 0.05) were observed among breeds in SP-OXT concentration
