Abstract:

The present study was designed to investigate the effect of extracts of medicinal herb which major component is barrenwort on frozen dilute sperm quality in northern shaanxi cashmere goat. Four simple prescriptions and one compound prescription were added into dilute sperm, according to volume fraction 5%, 10%, 15% and 20%, respectively, and then frozen semen straws. The indexes of sperm activity rate, deformity rate, acrosome abnormity rate, survival time at normal temperature, effective survival time were analyzed, compared to that of control group. Results indicated that thaw sperm quality was the best among these groups when added 10% compound prescription extracts of barrenwort, morinda officinalis, dodder, actinolite, glycyrrhiza. Average of sperm activity rate, deformity rate, acrosome abnormity rate, survival time at normal temperature, effective survival time were 0.433, 14.28%, 16.64%, 8.00h and 4.56h respectively when added compound prescription into spermatozoa diluent. Results support that extracts of medicinal herb improve thaw sperm quality.
