[QUOTE="Lucky_P, post: 1799052, member: 12607"] Simme, I was trained to to BSEs while in vet school and did quite a few while I was in practice. My last 28 years were spent in a veterinary diagnostic lab setting, and we did semen evaluations - though only one local practice was close enough to bring fresh-collected samples for examination (When I was in practice, I had my own microscope and warming chamber... did the entire thing on-the-farm, from palpating testicles/internal organs to examining extended penis, collecting semen and doing semen evaluation.. Semen evaluations at the D-lab were done mainly by the technician in the clinical pathology lab - but I performed evaluations when she was out, and we cross-checked one another at our semi-annual competency exercises. I've only examined a few straws of frozen/thawed semen, and the best I can say is: Frozen semen is a very different 'creature' from semen collected at chute-side. MUCH lower numbers, and motility, to my eye, was really slowed. I've not reasearched what parameters indicate that frozen/thawed semen is acceptable, in many years. Certainly, if they're all dead, there's your answer. But if some/all are moving, albeit slowly, what's the verdict? IDK. [/QUOTE]
