Comparison of the Effect of Heterologous and Homologous Seminal Plasma on Motility and Chromatin Integrity of Stallion Spermatozoa Selected by Single Layer Centrifugation

Table 1

Changes in the mean proportion of spermatozoa showing progressive motility (all, Class A, and Class B) after SLC and after the addition of own (homologous) or foreign (heterologous) SP to SLC samples ().

Kinematic	SP added 0 h, motility 0 h			SP added 0 h, motility after 24 h storage			SP added after 24 h
Progressive motility (%)	SLC only, no SP	Own SP	Foreign SP	SLC only, no SP	Own SP	Foreign SP	SLC only, no SP	Own SP	Foreign SP
All (%)	62 ± 17	62 ± 13	64 ± 18	61 ± 18^ab	70 ± 15^a	68 ± 15^b	61 ± 18^cd	73 ± 15^c	69 ± 17^d
Class A (%)	23 ± 14	24 ± 17	27 ± 16	31 ± 17^f	40 ± 18^f	29 ± 15	31 ± 17	47 ± 19	41 ± 23
Class B (%)	40 ± 11^e	37 ± 10^e	37 ± 13	30 ± 10	29 ± 11	39 ± 8	30 ± 10	26 ± 10	28 ± 13
