(g = gram, mg = milligram, mcg = microgram)
A rat will typically eat about 15 g of dry food blocks a day. So a kg of diet will feed between 52 and 76 rats, depending on their size. A rat needs about 60 calories a day depending on size.

Approximate need
Vitamins for one rat per day
A 0.6 mg/kg of diet 0.11 - 1.2 mcg or 0.37 - 4 IU
D 1000 IU/kg of diet 13 - 19.2 IU
E 35 mg/kg of diet 0.46 - 0.67 mg or 0.69 - 1 IU
Niacin 20 mg/kg of diet 0.26 - 0.38 mg
Pantothenic Acid 8 mg/kg 0.1 - 0.15 mg
Riboflavin 0.8 mg/1000 kcal of diet about 0.05 mg
Thiamin 4 mg/kg of diet 0.053 - 0.077 mg
B6 7 mg/kg of diet 0.09 - 0.13 mg
B12 50 mcg/kg of diet 0.66 - 0.96 mcg
(For Vitamin A, 1 IU = 0.3 mcg, for Vitamin E one IU = 0.67 mg)
Vitamin A is one of the few vitamins that can cause problems if the dose is too high. Chronic toxicity symptoms are hair loss and dry rough skin
Minerals
Calcium 5 g/kg of diet 0.066 - 0.96 g
Phosphorus 4 g/kg of diet 0.05 - 0.77 g
Flouride 1 mg/kg of diet 0.013 - 0.019 mg
Iodine 0.15 mg/kg of diet 2 - 2.9 mcg
Chloride 5 mg/kg of diet 0.066 - 0.96 mg
Iron 35 mg/kg of diet 0.46 - 0.67 mg
Copper 5 mg/kg of diet 0.066 - 0.96 mg
Magnesium 800 mg/kg of diet 10.5 - 15.4 mg
Potassium 35 mg/kg of diet 0.066 - 0.0.67 mg
Manganese 50 mg/kg of diet 0.66 - 0.96 mg
Sulfur 3 mg/kg of diet 0.039 - 0.058 mg
Selenium 0.1 mg/kg of diet 1.3 - 1.9 mcg
Zinc 12 mg/kg of diet 0.16 - 0.23 mg
Chromium 0.3 mg/kg of diet 3.9 - 5.8 mcg
(note: other research has shown that giving chromium picolinate at 189 mcg/lb daily extends the lifespan of rats)
