The involvement of beta-1,4-galactosyltransferase and N-acetylglucosamine residues in fertilization has been lost in the horse

Table 3 Number of fresh or frozen spermatozoa bound to the zona pellucida per oocyte incubated with or without purified GalTase.

Groups		Galactosyltransferase	No additive
Fresh semen	No. Oocytes	43	42
	Spermatozoa/oocyte (mean ± SEM, n = 3)	99 ± 6	104 ± 12
Frozen semen	No. Oocytes	40	40
	Spermatozoa/oocyte (mean ± SEM, n = 2)	89 ± 5	91 ± 7

No statistical difference was observed between the columns in the same line (for fresh semen F = 0.14 and p = 0.70, for frozen semen F = 0.06 and p = 0.80)
n: number of replicates
