The aim of this work is the comparison of sodium, calcium, magnesium and phosphorus concentration in pre-ovulatory follicles and follicular cysts and their concentration in the serum of sows. The research was conducted on sows (Polish Large White x Polish Landrace crossbred). Sodium concentration in cystic fluid was higher than in the follicular fluid (P<0.05). Sodium concentration in the serum of cysts-bearing sows was higher than in non-cysts-bearing sows (P<0.01). Differences were also observed between cysts and serum of cysts-bearing sows (P<0.01), as well as follicles and serum of non-cysts-bearing sows (P<0.01). Calcium concentration in the serum of non-cystsbearing sows was higher than in the case of cysts-bearing sows (P<0.01). Differences were also between calcium concentration in the cysts and its concentration in the serum of cysts-bearing sows (P<0.05). Magnesium concentration in the serum of cysts-bearing sows was lower than in non-cysts-bearing sows (P<0.01). Differences in magnesium concentration were also between cysts and serum of cysts-bearing sows (P<0.01), as well as between follicles and serum of non-cysts-bearing sows (P<0.05). Phosphorus concentration in the cysts was lower than in the follicles (P<0.05). It was also lower in the serum of non-cysts-bearing sows than in the follicles (P<0.05). The concentration of sodium, magnesium and phosphorus in the serum was positively correlated with the concentration of the mentioned macro-elements in ovarian structures (r = 0.66, P<0.01; r = 0.49, and r = 0.48, P<0.05, respectively). A negative correlation was found between the concentration of serum calcium and the ovarian structures (r = -0.47, P<0.05).
The differences in the concentrations of macro-elements suggest that the ionic composition may be one of the factors associated with the processes occurring in the ovarian structures of pigs.
