Age-Related Dynamics in the Conventional, Non-Conventional, and Bacteriological Characteristics of Fresh and Liquid-Stored Porcine Semen.

ABSTRACT: This study strove to investigate the effect of boar age on conventional and non-conventional quality traits of fresh and liquid-stored semen. Sixty boars were allocated into 3 groups: 8-12 months (young); 24-36 months (adult); and 48-60 months (senior). Ejaculates were divided into two parts; the first one was assessed in native state while the second one was extended in the Androstar Plus extender containing gentamycin, stored at 5 °C and evaluated following 72 h. Young animals presented with a significantly lower sperm motility (p < 0.01), membrane and acrosome integrity (p < 0.0001), and mitochondrial activity (p < 0.0001) against adult boars. Significantly higher levels of free radicals and tumor necrosis factor alpha (p < 0.001), interleukin 1 and 6 (p</
