Low volume and lower concentration....

Postby smoky » Wed Apr 16, 2014 2:28 pm

Hey Jos,

I wrote to you last year about our stallion,
"Our stallion last year started out the season with 30 ml of gel free ejaculate but would stay in that 45-60 ml after a few times of collecting him.

This year he is at that 20 ml range and is lucky if we get 30ml. Concentration has been good and under microscope everything looks great. He is running in that 900-1000 mil/mL range.

Is there anything we can do to help him increase volume? Should we even worry about the volume since he is packing a punch with his concentration?

Thoughts?"


So here's an update to our stallion. We've been getting 10 ml of semen again in the 900-1000 mil/ml and great motility so we haven't worried much.

However, today when we collected, we barely got 4 ml of semen and the concentration was only 450 mil/ml. What's going on? What can we do to help this? He has a low libido as well, but if a mare is in heat we've never had a problem getting him to collect. He doesn't look sick or unhealthy and hasn't been in training. Nothing has changed for him in his environment.

When we first started collecting him, we used latex liners but the past two seasons have used disposable liners. Is this causing that much of a difference? I had no problem using the latex liners other than I didn't feel like we could get it clean enough. Any tips or suggestions on what to do?

I appreciate any and all help!

As I am sure I said last year, looking at the total number of sperm in the ejaculate is more important than the volume or concentration individually (which by themselves are irrelevant). The above total sperm number of 1.8 billion is low. There are factors sometimes unknown to us mere humans that can affect a stallion's desire to ejaculate completely - the tease mare may not be to his liking; the AV might be less than desirable in its make-up (too hot, too cold, too tight, too loose, not held right etc.); the person handling him or the AV may have caused intimidation at the wrong moment etc. etc. so something outside the stallion may have impacted something inside the stallion. Consequently, these numbers can and do vary between collections. If you are consistently getting low total sperm numbers then evaluation of the stallion's testicles to confirm an estimated daily sperm output based upon testicular volume can be useful to determine if there is a physical problem or not (if his testicles are small it may indicate that he is in fact giving all he's got).

When we first started collecting him, we used latex liners but the past two seasons have used disposable liners. Is this causing that much of a difference? I had no problem using the latex liners other than I didn't feel like we could get it clean enough. Any tips or suggestions on what to do?


If you have only just started seeing a change in ejaculate quality and - as you indicate above - nothing else has changed environmentally, then the disposable liners are not the issue.

If things are not going as desired, then the solution is to change something. Start by adjusting the AV - warmer, colder, tighter, looser - change the variables and see what happens. Have someone else handle the AV and see if that makes a difference. Play around to see what a change in a certain area makes. Try to do only one change per collection so that you can definitively identify a positive or negative response.

Finally, bear in mind that stallions, like mares, are seasonal breeders. In the height of the breeding season - and by "height", a stallion is thinking May and June - his sperm output may be double what it is in the winter period of the year, so what you are seeing may in fact be a reflection of seasonal variation with that particular stallion (some stallions are more seasonal than others).
We're always happy to try and help, but don't forget to check the articles section
of the website too, which has a search engine to help you look for answers!
