Effect of bovine serum albumin on motility and fecundity of turkey spermatozoa before and after storage.
Motility characteristics of turkey spermatozoa before and after storage for 24 h at 7 degrees C in diluent with and without bovine serum albumin (BSA; 1% final concentration) were measured by computer-assisted semen analysis. BSA significantly increased the percentage of motile spermatozoa and sperm velocity, linearity, lateral head displacement and beat frequency in each treatment, but BSA in fresh or stored semen in diluent did not augment hen fertility over 15 weeks of egg production. Fatty-acid-free BSA, globulin-free BSA and Fraction V BSA all significantly increased each sperm motility characteristic compared with semen in diluent alone. The lack of correlation between sperm motility and fecundity emphasizes the need to develop procedures for semen evaluation that accurately predict the fertilizing capacity of an aliquot of semen.
