Studies like this drive me nuts.
First, all of these horses were supposedly normal, nonobese horses. Average weight was 1100 lbs.
They fed the horses hay that was 0.4% starch and 5.4% ESC. This is a nice low sugar+starch hay.
Then, they fed these horses an average of 5 1/2 lbs of grain consisting of corn, oats, barley and molasses. The starch was 34.7%, the ESC was 2.8%.
As we know starch breaks down into glucose + glucose. ESC breaks down into glucose + fructose. It's the glucose number that causes the insulin to rise.
Then, they fed 3 oz, or 6 oz, or 9 oz, of psyllium pellets. The psyllium pellets were 17.2% starch and 2.2% ESC. (These are high numbers for sugar and starch.)
They fasted the horses overnight, then fed them the grain with the psyllium pellets mixed in, and their hay.
They claim that the blood glucose levels were lower and the insulin values were lower with feeding psyllium.
But the crazy part was that the area under the curve was the same for glucose and for insulin for the treatment group and the controls. The peak just wasn't quite as high.
When they did the intravenous glucose challenge, there was no difference in mean glucose response, no difference in area under the curve, and no difference in the time to peak glucose. As for insulin, there was no difference in area under the curve, no difference in peak insulin concentrations, no difference in time to peak insulin.
And none of this work was done on insulin resistant horses.
So, if you want to reduce the glucose and insulin response, why not remove the 6 lbs of oats/corn/barley/molasses? Replace it with beet pulp.
I just can't think of any practical reason for this study.
And I certainly would not extrapolate any of these findings to say that psyllium is good for lowering the insulin response in insulin resistant horses. The data just doesn't support this sort of leap.
To lower the insulin response in insulin resistant horses, the best method is to feed low sugar/starch hay, with beet pulp. And get plenty of exercise.

ok danke Katie.katiebell hat geschrieben:Die Studie muss man sich etwas näher ansehen, um zu verstehen, dass sie für IR Pferde keine Rolle spielt. Hier ist ein hilfreiches Zitat:Studies like this drive me nuts.

auch die hats mit begeisterung gefressen.
Hach, ich freu mich grad so!!!Und das ist das Blutbild das ich direkt in der Klinik habe machen lassen weil sie diese Woche ja eh dort stand:Glucose: 83 mg/dl
Insulin: 17.9 uIU/ml Note: uIU/mL = IU/L = U/L = mU/L
Results:
If the G:I ratio is less than 4.5, horse is severely IR. If the G:I ratio is between 4.5 and 10, the horse is compensated IR. A G:I ratio greater than 10 is normal.
G:I ratio = 4.64
A RISQI greater than .32 is normal. A RISQI less than .32 indicates IR. A RISQI less than .22 indicates severe IR.
RISQI = 0.24
Some horses will have a normal G:I ratio and RISQI but still be in danger if the glucose is over 100. An MIRG greater than 5.6 will indicate IR in these cases.
MIRG = 9.26
IR Status = Compensated IR, laminitis risk
