Inclusion of bovine serum albumin in semen extenders to enhance maintenance of stallion sperm viability. Abstract Text:

J L Kreider,W C Tindall,G D Potter,

Semen from seven mature stallions was used to test the motility response of sperm cells when 3% bovine serum albumin (BSA) was added to seminal plasma and skim milk diluents. A total of 45 ejaculates was collected by artificial vagina and immediately evaluated for percent motile spermatozoa (PMS), rate of forward movement (RFM) and sperm cell concentration. Aliquots (four from each ejaculate) of raw semen containing 500x10(6) sperm cells were exposed to each of the following treatments: (1) seminal plasma (SP), (2) SP+BSA, (3) skim milk (SKM), (4) SKM+BSA; and incubated in 50-ml tubes at 37 C. The sperm cell characteristics, PMS and RFM, of each treatment suspension were reevaluated at 0, 0.5, 1, 2, 6, 12, 18 and 24 hr post-treatment. Inclusion of BSA and the type of extender, either seminal plasma or skim milk, significantly (P<0.05) affected the PMS and RFM of spermatozoa. Analysis of means within evaluation times showed that PMS maintenance was enhanced (P<0.05) when BSA was included in extenders at all incubation intervals except 24 hr. SKM+BSA maintained the highest (P<0.05) PMS for the first 2 hr with SP+BSA sustaining the highest (P<0.05) PMS from 12 to 24 hr. Skim milk alone sustained higher (P<0.05) PMS than the SP diluent for the first 6 hr of incubation, whereas SP maintained a higher (P<0.05) PMS than SKM from 18 to 24 hr. The RFM of spermatozoa was greatest (P<0.05) for the first 6 hr of incubation when exposed to SKM+BSA. Seminal plasma + BSA sustained a higher (P<0.05) RFM for the first 6 hr of incubation than SP alone, but not higher than SKM at this interval. Skim milk sustained a higher (P<0.05) RFM of spermatozoa for the first 6 hr of incubation than SP. These data support the hypothesis that BSA protects spermatozoa from the harmful effects of lipid peroxidation. Including this substance in semen extenders may prolong maintenance of sperm motility.
