Impact of the Balance Cooling the Bulls Frozen Semen Quality

Cooling down balancing is to freeze important link in semen procedure of production. Test that the semen that kind of bull produces with the unit is a sample book, instrument equipment such as using the low temperature to balance a chest,measuring the temperature instrument,the microscope, studies an impact of cooling balance over the mass freezing semen. Result indicates a dilution law, adopts proper thin tube semen quantity is 100 ～ 300 branches in beautiful dress in every box; Adopt repeated diluting law, semen dilutes proper capacities of queen in every beaker being 50 ～ 120 milliliters. After adopting the balance first, drinking wine holding the balance cooling down the day after tomorrow with and cooling down first drink wine holding two kinds different method with, The effect difference to the mass freezing semen is not notable( 0.05). Under the environment balancing the chest temperature being 4℃, Semen falls to 1 ～ 1.5 hours balancing proper the temperature time being from the temperature diluting the queen , balance time is 3 ～ 4 hours.
