Just had a ram Collected .He was very fertile. Got 8 ml on an ejaculate, and had to extend twice what considered normal to even get a good count.
He had bred 20 ewes from august 14 to august 28.
This was done t Iowa State.
They have tested a lot of rams,10 the day I was there.
over fifty percent were as yours is. I was glad mine was good and successfully froze semen. And survived post thaw.
Point being, they test hundreds of rams per year, and many will fail until late august or september.
A lot of rams have been sidelined in midwest,because of heat ,humidity .
May take 8 weeks to recover. An agressive mineral program seems to help. As does shade,breeding at night,fans and manageing breeding to conserve ram serving capacity. Maybe you have been lucky , and not had a problem .
Based on semen test, your ram is producing . You would be hard pressed to collect anything.Most auctions have specific criteria to deem a ram non producer.Including returning to breeder ,at your cost.The ram has to be in at least as good of condition, weight as when you recieved him. And breeder has right to use ram himself.If he settles ewes for breeder , your out.
That being said, I have sold one bad ram .15 plus years ago, a ram lamb sold at Sedalia to Pennsylvania. Buyer noticed ram lamb remarking,tested and 100 percent deformed.
They bred ewes to back up ram, and waited 3 months to retest. Still dead.
Sent ram to sale barn.They took pick out of my Sedalia consignment the following summer.And sent me check for salvage value of ram.I did not ask for or expect that.They were happy with replacement. I could have had them return ram.O trusted thier vet.
Talk to the breeder,and see what they have to say.
This one may be chalked up to tution.
