Ivermectin and bulls.

I don't know but suspect it could because it works to interfere with the channels that effect nerve cells. Since ejaculation depends on nerves, it might but I don't think it would be permanent, however I don't know with any degree of certainty.

If his problem is dietary, then supplementing a dry feed might help. If it is parasitic then the Ivermectin should help. If it is viral, then it might or might not help.

It sounds dietary, so maybe address that first.

I have a yearling bull that goes through bouts of diarrhea. He has had SafeGuard, and it is possible it has more to do with the grass kicking in.
But was thinking if I were to treat him again I might use the Ivermectin.

Ivomectrin isn't the best for deworming. Cattle are becoming immune to it. SafeGuard is best; gets more
types of parasites over a longer period of time. We offer SafeGuard in our mineral so it can work over a longer period of time.

I have been fortunate to have personally worked with Dr. Bliss:
"In the past two to three years, it has become evident that the modern anthelmintics upon which the American cattle industry relies have begun to show diminished efficacy," said Dr. Don Bliss, parasitologist at the MidAmerica Agricultural Research Center, Madison, Wis., who has monitored thousands of fecal samples from cattle throughout the United States over the past 20 years. Bliss said he sees examples of anthelmintic resistance on a daily basis.

This was from 2005, so kind of old news. Dr. Bliss was very brave in sounding the alarm several years ago,
when most didn't agree with him. But his findings have proven to be right.

I have read that Ivermectin can/might affect bull fertility. Is this a concern ?

I think this comes from the false rumor that human males taking Ivermectin would go sterile. This baseless info came out to discourage people from taking it to ease the effects of Covid. It has been proven false. I can't find anything that indicates it would be a problem in male bovines.

Thanks. he went through a treatment for coccidiosis when I first got him about 6 months ago, so I wouldn't think he would have a repeat of that. I will keep stuffing as much hay into him as possible :) It always looks so much worse for a light colored animal to get diarrhea. I think he will shed off to be sort of a silver grey Murray Grey so it is very noticeable.

I should have him back over to my place pretty soon and can put him in the chute and curry all the ickkys off his bottom.
