DURASHELL® is a specifically formulated combination of organic trace minerals to increase eggshell quality. Trace minerals in DURASHELL® are neutrally charged so they do not dissociate. Trace minerals in DURASHELL® also do not interact with other minerals. Therefore, the bioavailability of trace minerals in DURASHELL® is much higher than trace minerals in sulfate or oxide forms.
DURASHELL® should be used in layers and breeders feeds in the amount of 1 kg/ton.
