Abstract:
Animal artificial insemination (AI) suffers from bacterial contamination of semen media which results in decreased success of the process of artificial insemination. It is difficult to treat the semen extender medium to reduce the bacterial growth in the presence of semen using the conventional techniques of bacterial inhibition. In the present work, a new optical method developed for bacterial growth inhibition in semen containing extender medium using diode laser (DL) and commercial cheap light emitting diode (LED) is presented. Certain wavelengths and exposure times suitable for the process of artificial insemination are found to be optimum at reducing bacterial growth with a minimum significant effect on the semen motility and viability.
