Abstract
OBJECTIVE: The objective of this study was to compare the biochemical composition of follicular cysts, pre-ovulatory follicles and serum in sows. MATERIAL AND METHODS: The research involved multiparous sows (cysts-bearing sows, n = 21; non-cysts-bearing sows, n = 22). Concentration of glucose, protein, cholesterol (CHOL), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triacylglycerol (TAG) in the samples was determined. RESULTS: Glucose concentration in serum was higher than in cysts and follicles (p < 0.01) and glucose concentration in cysts was higher than in follicles (p < 0.01). Differences were also observed between the concentration of glucose in serum of cysts-bearing and non-cysts-bearing sows (p < 0.01). Protein concentration in cysts and follicles was lower than in serum (p < 0.01). Concentration of cholesterol in the serum of cysts-bearing sows and non-cysts-bearing sows was higher than the one in cysts and follicles (p < 0.01). Cholesterol concentration in the serum of cysts-bearing sows was higher than the one in non-cysts-bearing sows (p < 0.01). Concentration of HDL in serum of both cysts-bearing and non-cysts-bearing sows was also higher than the one in cysts and follicles (p < 0.01). Cysts-bearing sows had a higher concentration of HDL in the serum than non-cysts-bearing sows. Differences were also observed between the concentration of HDL in cysts and the one in follicles (p < 0.05). LDL was determined not to be present in either cysts or pre-ovulatory follicles. TAG concentration in the serum of cysts-bearing sows was higher than the one in the serum of non-cysts-bearing sows (p < 0.05). Differences were also detected between the TAG concentrations in cysts and in follicles (p < 0.01). CONCLUSION: The differences in the biochemical composition of the fluid in follicular cysts and pre-ovulatory follicles point to the variable intensification of the course of metabolic processes in pathological and physiological ovarian structures.
