Re: HELP!!! Feeding a nervous/flighty horse
Of course the supplier would recommend you keep feeding it - they want more sales don't they?
Alfa-A & speedi are both good but high energy feeds, so if your horse is a good weight, yes, it's good to watch the quantity. I gather he's getting grass/hay? What exactly is the oat & barley free mix? That is probably what I'd cut first, tho don't know what's in it. Why do you want a high fat feed if he's a good weight? Fat is also an energy source.
His nervous behaviour could be due to a nutritional imbalance rather than purely too much energy. Eg. lack of magnesium can make horses more edgy. Is he getting a good nutritional supp? If not I'd advise that, which could include linseed/flax, which is a good source of essential fatties. I'd also put him on a probiotic, after the antibiotics, as his 'nervousness' could be due to gut upsets or such, from the drugs, being cooped up, starchy diet &/or inappropriate feeding, that may have also happened.
