Table 1 Boar age, ejaculate characteristics and sperm functional parameters in liquid-stored semen (n = 36) for each of the two groups of SP-samples grouped hierarchically (P < 0.001) according to OXT concentration

From: Oxytocin in pig seminal plasma is positively related with in vivo fertility of inseminated sows
