Specialty Feeds: SF00-213 High Zinc (1000mg/Kg) Semi Pure Rodent Diet

Diet: SF00-213 High Zinc (1000mg/Kg) Semi-pure Rodent Diet

A semi-pure diet formulation for laboratory rats and mice based on AIN-93G.

Zinc content has been increased to 1,000 mg / Kg by the addition of Zinc Sulphate to the trace mineral premix.
Zinc toxicity in rats or mice has not been clearly defined. Studies have indicated that under certain circumstances dietary zinc concentration in excess of 250 mg Zn / Kg diet leads to symptoms of toxicity. A more generally recognized toxic concentration is 5,000 mg Zn / Kg diet. The LD50 for Zinc Sulphate is reported as 1,700 - 2,000 mg ZnSO₄ / Kg, this equates to a zinc concentration of 650 mg Zn / Kg diet.
This diet was designed for a very short term feeding trial in SD rats.
Feed is manufactured as a 12 mm diameter cube, vacuum packed.
