What is the Correct Way to Check Repeatability in Balances?

Zoalene is usually added to feed in doses of 125 ppm (preventive) or 250 ppm (curative). It is a broad-spectrum anticoccidial drug, preventing seven main strains of Eimeria coccidium. It leaves no residues in tissues. It can be also used to prevent coccidiosis of domestic rabbits.

If zoalene is held at 120-125 °C for 24 hours or longer, it may react and self-heat and even explode.
