Enhancement of frozen-thawed quality of bull semen after enrichment of docosahexaenoic acid extended in tris- extender

The present study aimed to depict the quality of frozen-thawed bull sperm extended in Tris-buffered extender (TBE) supplemented with docosahexaenoic acid (DHA). Electro ejaculator was used to collect the semen and ejaculates having ≥ 20 × 109 spermatozoa with an initial motility rate above 70 %, and...

Electro ejaculator was used to collect the semen and ejaculates having ≥ 20 × 109 spermatozoa with an initial motility rate above 70 %, and normal morphology and viability of ≥ 80 % were extended in TBE, to which different concentrations (0, 3, 5, 10 and 15 ng/ml) of DHA were enriched.

Consequently, straws were thawed at 37C0 for 30 seconds and motility was accessed with the help of computer-assisted semen analyzer (CASA) and membrane integrity with the hypo-osmotic swelling test.

Level of TBARS was higher (p < 0.05) at 15 ng/ml as compared to other DHA supplemented and control groups.
