Keywords: pigs; boar; ejaculate volume; motility
The main objective of this study was to evaluate the effect of age (A) and the intensity of the boars' utilization (s) on the phenotypic variability of ejaculate volume (VOL) and sperm motility (MO). The study included 274 ejaculates of Large White boars (LW). Boars were divided into six classes according the age when the ejaculate was taken (10-13, 14-17, 18-21, 22-25, 26-29 and ≥30 months). Semen samples were analyzed during four seasons (spring, summer, autumn, winter). The intensity of the use of boars was seen as the impact of the group (class) of intervals between two successful collections (I; ≤ 5 , 6, 7 , 8, 9-10, 11-13, 14-21 days). Data processing was performed using the GLM procedure using the statistical package SAS 9.1.3 (SAS Inst. Inc., 2002-2003). Average values of VOL, MO, I, A, were: 178.94 ml, 90.35%, 9.37 days and 655.93 days. The effect of boars on both studied sperm traits was highly significant (p<0.001). The volume of ejaculate varied under the influence of boar age (p<0.001) and season (p<0.01). The effect of I on VOL and MO was not significant (p>0.05). Traits VOL and MO varied (p<0.001) between boars which indicated the need for individual control of each of boars used for artificial insemination. The highest VOL was determined in boars at the age of 26 to 29 months, and the difference to the boars aged 10-13 months was 62.70 ml (p<0.001). No statistically significant differences in regard toVOL between boars older than 17 months (from class 3 to 6) were recorded. The highest differences between winter and spring period were determined in mean values of VOL (32.15 ml; p<0.01). In the winter period, boar ejaculate volume was lower than in the autumn (-26.57 ml) and the difference determined was statistically significant (p<0.05).
