- Effect of spermatozoa incubation in the presence of anti-Prt serum (APPA) or pre-immune serum (CSerum) in the fertilization medium on embryo production rates in 4 replicates for cleavage and 3 replicates for D6/7 embryos (least squares means ± standard error). n: total number; data within columns with different superscripts are statistically different (P ≤ 0.05); Cleavage rate: number of cleaved embryos per number of inseminated oocytes; D6-7 embryo rate as the number of morulae and blastocyts at these days per number of cleaved embryos.
