Table 6.

Reproductive parameters obtained 6 days after heterologous seminal plasma (SP) or Beltsville Thawing Solution (BTS; control) infusions 30 min prior to insemination.

Group	No. of sows	Corpora lutea	Oocytes-embryos	Recovery rate (%)	Viable embryos	Fertilization rate (%)
SP	16	25.7 ± 8.4	24.3 ± 8.6	94.8 ± 14.1	22.6 ± 7.3	94.3 ± 11.8
BTS	18	24.9 ± 5.6	22.8 ± 5.1	92.0 ± 9.7	21.1 ± 6.4	91.3 ± 14.9

Data are mean ± standard deviation (six replicates). Means of corpora lutea, oocytes-embryos and viable embryos were compared by using unpaired Student t-test. Means of percentage data (recovery and fertilization rates) were analyzed using Mann Whitney U-test for two independent samples.
