Modified Artificial Vagina for Semen collection from Bulls.

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.
