Sweetfeet-nitrate poisoning

Just fyi -

You mentioned in your reply to my post about Tifton 85 bermuda, that your daughter had said some horses got nitrate poisoning from it.

I asked where she got that, and you told me she read it in Barrel Horse World. I contacted Barrel Horse World about the article. They replied and gave a link to the article.

The article was from Colorado State University and was about forages in general. I read it and it didn't mention Tifton 85 or any incidents of nitrate poisoning in horses from Tifton 85.

Since the article was in BHW, perhaps your daughter assumed some horses had gotten nitrate poisoning.
 
Hi, Nancy. Must have been a reply from a different person. But perhaps they will notice the nitrate poisoning in the subject and will read it too.
 
It is actually pretty hard to kill a horse by nitrate poisioning, especially with hay, average horse is not going to eat enough at one time to kill him. At the average fertilizing rates for grass hay, say 60 units of N per acre, as long as you get any rain at all between application and harvest it will not be nitrate stressed enough to kill a horse. Ruminants, cows, sheep, goats are a different story.

As I stated my daughter emailed the BHW article a month or so back. There could have been some more revelations since I first read the article on the supposedly nitrate horse poisoning. I'll ask my daughter as she reads BHW regularly.

Thanks, Jim. Contacted my ag agent and he didn"t know of any reports of nitrate poisoning from 85.

Very interested in following up on this.
 
Nothing related to nitrate poisoning but for those caught in this drought,be vigilant in preventing livestock breaking into johnson grass because it will definatly kill them. Don"t get me wrong,I"ve fed tons of j.grass as hay and grazeing. The problem usualy arises if j.grass is under or recovering from stressed growing conditions.
 
You are absolutely correct. JG is well know for causing poisoning under stress conditions.

We didn't have enough of it in our pasture to cause a problem. I don't think it lasted but one growing season. Horses ate it to the ground, then pawed up the roots and ate them.
 
What I am learning from this forum is that the information and feedback you receive is worth exactly what you paid for it.

No brag, just fact.

Yep,arn't momma nature smart? Had that been a large stand of JG that was in jepordy of being wiped out because it was stressed,the animals would never made it to the roots. I am happy to know that as a horse person you don't believe the fable about horses unable to eat JG under any cercumstances. I can't speak for horses but I've baled drought JG for cows without problems. Humidity and sun was ideal for cureing and might have made a difference.
 

Nancy, there was a case around Elgin where some stressed ropin' steers were turned in on a lush field of T-85. Some or all died, I don't recall exactly how many. But it was attributed to the condition of the animals and recent fertilizer application plus the drought conditions. The examiner concluded it was nothing particular to T-85, mostly the stressed condition of the animals to begin with. There was an effort to blame the deaths on GMO grass species which the hybrids of bermuda grass are not GMOs. The incident had nothing to do with GMO plants.
 
I read a report of that incident. Its the only incident of prussic poisoning attributed to T85 that I have been able to find.

According to what I read, the conditions that lead to the poisoning were pretty unusual.
