SF01-017 Low Iron, Semi-Pure Rodent Diet
A semi-pure diet formulation for laboratory rats and mice based on AIN-93G.
- Iron content has been decreased to <10 mg Fe / Kg diet by exclusion of any added Fe to the
trace mineral premix.
- In addition higher purity minerals have been used to minimise trace level contamination of
iron in this raw material.
- The careful selection of raw materials has allowed us to reduce dietary in this diet from what
was previously achieved. Recent analysis of this diet (in powder form) has shown that the
average Fe level in this diet is 2.5mg/Kg
- The generally recognised minimum iron requirement in rats and mice is 35 mg Fe / Kg diet for
maintenance and growth and 75 mg Fe / kg diet during pregnancy and lactation. Diets
showing clear symptoms of iron deficiency are generally in the range of 2 – 10 mg Fe / Kg
- Whilst this diet has an iron concentration less than known requirements, it was not designed
as a diet leading to rapid symptoms of iron deficiency.
- The pelletised diet has an increased iron content than the powder form. Typically in the
range of 15 – 20 mg Fe / Kg.
- A suitable control diet is AIN93G or AIN93M
- This diet is the base diet for a number of controlled Fe diets, including SF07-082 with 2% Carbonyl Iron
