We have flushed our Hairy donor twice this yr. Both times the semen we have used has been poor quality. The technician AI her always tests the semen before doing it. On the first bull it showed really low mobility so just to be safe we put in 5 straws. We got 10 eggs out of the deal so i can live with using that many straws. But Thursday ahead was bred for her her flush next week and when checking the semen the vet said mobility was low again and more or less half of the straw was dead so again we put in 5 straws. Hope it pays off again! Just curious if anyone else has had problems like this and what can u really do to get higher quality semen?
