First, I want to say THANK YOU to everyone weighing in on this. I have certainly spent a great deal of time & energy trying to make sense of all this- especially to PREVENT IT from ever happening again!
To respond to some of the very valid questions:
This began in Jan 2018- several months ago. At the time, I had no reason to think the feed was a contributing component- so at this time I do not have lot numbers from bags, but I am following up with the person that sent me her report to see if she has the numbers. At this time, the report can be found on the ECIR website, along with independent reports on several feed manufacturers & the different feed types- not just this one.
Equianalytical Report:
WSC 9.9
ESC 6.7
Starch 8.7
Feed Co in question (on their website):
WSC 5.3%
ESC 5.3%
Starch 6.4%
Starch +ESC 11.7%
NSC 11.7%
Certainly, I am not an expert at calculating all this, but the independent analysis is dramatically higher in all categories and it’s my understanding Starch packs a bigger punch to the endocrine system.
Also, I do not think Laminitis is caused by any ONE thing (unless it’s a retained placenta, black walnut shavings)- I am speaking of an endocrinopathic type.
According to the ECIR: Diet, Diagnosis, Exercise, and Trim are all important factors.
While my horse at the time apparently DID have an underlying insulin resistance/ slight PPID, he was exercised frequently until we hit really bad weather in January in the SE. According to what I have read on ECIR, exercise is a huge insulin buster.
As I discovered the variance when the report was forwarded to me, coupled with the timing of the mill change, (and Purina is not exactly known for quality control), add in the Founder’s letter admitting he has been made aware of “inconsistencies”… and it’s been the only logical conclusion I can draw.
At the end of the day, I am just searching for answers & clarity. If any other horse owners had similar experiences during the timing of all this, it would add validity to my hypothesis that an increase in the feed’s Starch & Sugar was a contributing factor in his case.
Lastly, I am happy to say, PJ is doing pretty well under the circumstances. He is recovering from his second abscess& subsequent osteomyelitis, and is now wearing a grazing muzzle, & eats a feed & forage with a GUARANTEED analysis. NOT taking any chances!!!
Also, I am going to go back & edit my post, removing the Company name- for obvious reasons, & Thank You Texarkana for the clarification on the NSC calculation:-)
