Why are all my deer coughing??

2 weeks ago in my breeder pen, a doe fawn started putting her head down and coughing intensly for about 30 seconds at a time when all the deer were coming up to eat, she did this often. I did nothing to her, she was acting normal and had no noticable nasal drippage, but I decided to get some safeguard and worm the whole pen, I wormed again with another full dose of safeguard 4 days later. The fawn stopped or at least showed less symptoms. But now over the past 4-5 days I have had multiple other fawns and even 4-5 different adults starting this, and the fawn the started it off, is showing even worse symptoms tonight, but still acts normal and has no nasal dripping. I just wormed again this weekend and with a different type of wormer, a goat dewormer.

I can't figure why they are doing this, it is only the breeder pen, no other pens are. There is a huge amount of acorns in this pen, are the acorns possibly playing a factor in the coughing??

The other thing that came to mind is that i bought a doe off a friend and put her in the pen i am having this problem with, about 3 weeks ago, and he was having some coughing issues at his farm, no fatalities, but just alot of coughing he could not get rid of it. Maybe this doe brought a sickness is that is highly contagious?? The doe i got from him has not coughed yet since she got here.

I take pride in a healthy herd and this whole thing is starting to really upset me, I would like to see it stop, does anyone have any suggestions?? Thank you.

Ryan, Auromycin crumbles are added directly to my mix at the mill.



Mark, Yes! I never thought of it but the last few bales I fed were from the bottom of the pallet, even with my alfalfa bales being stacked on a pallet, my last row of 6 apperently picked up some moisture and were very dusty when i fed them, Will the deer get over the coughing on there own, or do you recommend antibiotics? I will not feed anymore dusty hay, those bales can go to the cattle.



AMW- Stools look great, very black, and very solid pellets, no concern on that end.
