BEST TIME OF A.I.: At the beginning of heat, very little mucus is present. As the estrous progress the mucus is transparent and observed in the floor of vagina. Towards the end of estrous it becomes cloudy which is the best time for breeding (24-30 hrs after onset of estrous or 24-30 hrs after showing the heat symptoms.). At the end of heat period the mucus becomes cheesy. While in case of cattle when the clear thick mucus is hanging from the valva to the floor is the best time for A.I. (16-18 hrs). Double insemination is also practiced in case of doe. First insemination at 24 hrs of onset of heat and second insemination at 12 hrs after first insemination.
