Abstract

© 2018 Blackwell Verlag GmbH The use of foetal bovine serum (FBS) in cell culture media is quite common. However, little is known about the effect of FBS on sperm. The severe difficulties in alpaca reproduction demand the search of new methods for in vitro reproductive management. In the present study, we use for the first time FBS as a supplement in the culture medium for sperm in alpaca, and the effect of FBS on motility, acrosome reaction and sperm binding to the zona pellucida in this species was evaluated. A concentration of 10% v/v FBS was used. The sperm motility with FBS at the first hour was 32.8% (vs. control = 30.0%), whereas at the second hour sperm motility with FBS was 30.2% (vs. control = 28.8%). The acrosome reaction reached an average of 44.0% for treatment with FBS (vs. control = 30.1%). The sperm-zona pellucida binding assay showed that the samples incubated with FBS had an average of 2.7 bound sperm (vs. control = 1.7). Only a significant difference was observed for sperm motility at the first hour and for the acrosome reaction. It is concluded that FBS favours the capacitation of sperm in alpaca.
