my gerbils are weird eaters and I have been trying to mix my own feed out
of stuff they actually eat based on the nutrition percentages on the web
site. but I have a question. Are the percentages by weight or by
calorie? that is, would 8% fat be about one gram of fat out of 10 grams of
food (that would be 9 calories out of 45, or 20 % of calories), or
would it be 8 calories (about 1 gram) of fat out of 100 calories of
food? (that would be one gram of fat and 23 grams of protein or
carbohydrate) There is a pretty big difference. (the sweeties are
such weird eaters that they won't eat seeds at all--even sunflower seeds.
Not even a nibble. How weird is that?) How much sodium should they
get? do I need to worry about other minerals, like calcium, if they are
not nursing or pregnant? |
