Background:
The temperature of artificial vagina is a critical factor for the semen collection of bulls. Lower AV temperature • Poor or fail to thrust • Fail to donate semen • If donate, low sperm concentration and chances of contamination of semen with urine. High AV temperature • Some sperm may be killed • Cause burning of penis and develop fear to donate in AV. Technology Details We have modified the existing AV. At the time of semen collection, some bulls take more time to donate the semen meanwhile the temperature of AV goes down from the required temperature. Routinely semen is collected in early morning and in winter season if the environmental temperature is very low in the situation AV temperature also fall down rapidly in that condition this modified AV helps to collector in changes the AV to get better semen quality. Generally young bulls require low temperature of AV while mature bull requires high temperature of AV to donate good quality of semen. In that condition, semen collector can identify the bulls which one requires high or low temperature of AV.
