Advances in Boar Semen Cryopreservation

Table 1

Cryosurvival (examined using Computer-Assisted Sperm Analysis, CASA) mean ± SEM percentages of total motile spermatozoa, 30 min post-thaw at 38^∘𝐶) of boar spermatozoa from P1 (1st 10 mL of the sperm-rich fraction, SRF) or the entire SRF when subjected to a simplified (SF, 3.5 h) or a conventional freezing (CF, 8 h) and an equal thawing (35^∘𝐶 for 20 s).

Simplified freezing (SF, 3.5 h)		Conventional freezing (CF, 8-9 h)
P1-spermatozoa	SRF-spermatozoa	P1-spermatozoa	SRF-spermatozoa
62.9±3.13^a	54.2±3.50^a	70.0±4.40^a	64.0±2.60^a
