Chromatin condensation but not DNA integrity of pig sperm is greater in the sperm-rich fraction

Table 2 Sperm concentration, oxidant activity (AOPP), total antioxidant capacity (CUPRAC) and oxidative stress index (OSi) results from the different ejaculate-fractions

	Concentration, spz/mL	AOPP, µmol/L	CUPRAC, µmol/L	OSi (AOPP/CUPRAC)
SRF-P1	1.34 × 10⁹ ± 1.88 × 10^8a	78.90 ± 15.60^a	188.40 ± 15.42^a	0.42 ± 0.06^a
SRF-P2	5.66 × 10⁸ ± 1.27 × 10^8b	48.25 ± 11.85^b	224.23 ± 41.66^ab	0.23 ± 0.09^b
PSRF	1.32 × 10⁸ ± 3.90 × 10^7c	20.15 ± 1.28^c	250.32 ± 9.58^b	0.08 ± 0.00^c

SRF-P1 First 10 mL of the sperm-rich fraction, SRF-P2 Rest of sperm-rich fraction, PSRF Post sperm-rich fraction. A total of 6 SP-samples were used for analysis, and results ptesented as mean ± standard deviation (SD)
^a,bDifferent letters mean statistical differences between ejaculate-fractions (P < 0.05)
