[QUOTE=Spellcheck]I've heard that during the winter they should be fed 3/4 grass hay and 1/4 straw, but I don't really feel comfortable feeding anything that much straw, and my horse(s) and other livestock can't have it, so I've just been feeding a straight low-nutrition grass hay, not the richer kind like timothy grass or orchard grass. My mare is also an easy keeper, but I've had to supplement her with a little grain and alfalfa pellets to make up for the gaps in the grass hay diet.[\quote]
Straw can be high in nsc too, as with grass hay & grain, etc. 'Poor' quality & native grass hay - compared to 'good improved' types are generally lower & therefore better for Horses. Donk may need restricting tho android grazing muzzle one option. Regardless of hay quality its likely deficient in nutrients, so supping appropriately is beneficial. Grain doesn't give much nutrition though & alfalfa may be too high in calcium, energy, etc, esp for a donkey. Id opt for a good min supp that was palatable alone or with very little feed.
Not very fat by donkey standards? Well considering the amount of grossly obese donkeys, I'd have to agree& I wouldn't call her obese either, winter coat may also be disguising a bit, but considering the very serious health probs common to overweigh animals I wouldn't be sweating but would be taking measures
