title: Motility and fertility of equine spermatozoa extended in bovine serum albumin and sucrose.
abstract: Inclusion of either 1 or 3% (w/v) bovine serum albumin (BSA) in 8.6, 10, or 12% sucrose enhanced the maintenance of equine sperm motility in vitro at 38 degrees C for 8 h. There was a trend toward higher percent motile spermatozoa (PMS) at 16 and 24 h of incubation in semen samples containing BSA than in those that did not. The highest concentration of sucrose (12%) was slightly less effective in supporting PMS than either of the lower concentrations. However, sucrose concentrations had no apparent effect on rate of forward movement (RFM) of spermatozoa. Pregnancy and foaling rates were similar for mares inseminated with semen extended in either cream gel or 3% BSA-10% sucrose.
