Ferret Nutrition
Food Comparison Chart
Ferrets are carnivores in the wild, they are made to eat meat. They cannot digest vegetable matter very well and can get sick from it. Their short digestive tracts pass food within 4 hours, often between 2 and 3 hours. So nutrients must be absorbed within that time. Vegetable matter takes a long time to digest - time that a ferret doesn't have. So, above all else, feed your ferret a food high in meat, preferably from a known source.
It is recomended that food be given to ferrets at all times so that they will eat when they are inclined. Growing kits and pregnant or nursing females will eat a lot more than your average ferret, so provide them with more than usual.

 Brewer's Yeast, a good vitamin B supplement
Beef products are questionable because of digestibility and allergic reactions.
Always the first ingredient:
Meat in some form (whole, meal, by-product...)
Always in the first three:

Never in the first three:

 Corn, Soy, Wheat
No by-products
By-products consist of such things as necks, feet, bones, blood, intestines, ligaments, and almost all the other parts not generally consumed by humans.
"Pet food provides a place for slaughterhouse waste and grains considered 'unfit for human consumption' to be turned into profit. This waste includes cow tongues, esophagi, and possibly diseased and cancerous meat. The 'whole grains' used have had the starch removed and the oil extracted -- usually by chemical processing -- for vegetable oil, or they are the hulls and other remnants from the milling process. Some of the truly whole grains used may have been deemed unfit for human consumption because of mold, contaminants, or poor storage practices." (An API Report)
Whole flesh is best, more of a natural diet. But they have more water, and there will be less actual meat after the water is taken out during processing. Meat meals are rendered, and unless the manufacturer makes it's own meal, the meals could consist of unfit tissue. Yum. By-products can be perfectly nutritious, but because the term covers anything, it can vary from bag to bag. It's at best uncertain, generally non-nutritive, and problematic at worst. There COULD be a link between slaughterhouse wastes and cancer and other diseases.
You will have to compromise, there is no one perfect food. It is advisable to mix foods anyways, in case the brand becomes unavailable, or you go on vacation, new good brands come out, your ferret develops an allergy, etc. Ferrets become finicky after a while, but if they know that different kinds of kibble are "food", they won't encounter a problem switching.
Whole ground rice the best grain
White rice is more digestible to cats and dogs, and is less likely to cause allergies than corn or wheat. Up to 20% of other grains can escape digestion. It's used in many ferret foods already. So it's likely the best to use with ferrets...
Avoid corn, wheat, and soy as much as possible. Soy has a lot of protein, and can greatly skew the amount available in the crude amounts in the analysis, especially if there are other vegetable proteins.
No generic meat or fat sources
"Poultry" and "Animal" labels could be misleading. The exact origins of such products is unknown. Many fats are collected from restaurants' grease traps and placed in steel drums. They can then spoil until they are picked up by rendering companies and mixed with preservatives.
Chicken fat (and other specific fats) probably aren't treated in such a manner and may not require the chemical preservatives (BHT, BHA, ethoxyquin).
"Animal" digest is a broth made from anything that once lived. Chicken digest will be quite nutritious and appetizing to ferrets. Many "natural flavors" are made from digests.
No chemical preservatives - BHT, BHA, Ethoxyquin
Although not proven toxic, they haven't really proven safe, either.
"While the law requires studies of direct toxicity of these additives and preservatives, most of these additives have not been tested for their effect on each other once ingested. Three commonly used preservatives, BHA, BHT, and EQ, have a proven synergistic effect that may lead to the development of certain types of cancer."
Natural preservatives include Vitamins C (asorbic acid) and E (tocopherol); HOWEVER, they are NOT as effective and so their shelf life - about 6 months - is shorter than food preserved with chemicals.
Liver, bone and blood meals
Liver might be nutritious, but it's used to filter toxins from the bloodstream, and could contain residues. Avoid it in large quantities.
Bone and blood meals aren't meat. They may add vitamins and minerals, but probably are best in smaller amounts, not a large percentage like I've seen in some less popular brands of ferret food. Don't avoid them, they are good for your pet (I think). They will also make your garden grow better, too.
Ferret food should have a protein content of 32-38%, fat content of 18-22% and fiber content no higher than 3%. It should not have corn in the first three ingredients and meat is better than meat by-products. Fish should be avoided. These foods have been rated according to these guidelines. One star assigned for each element.
