Vetark have spent several years working with their insect feeds BUG GRUB and GRUB GRUB to develop a single product which covers the needs of both groups (hoppers and mealworms) and to produce the best gut loading effect we can. Now we have NUTROGRUB - based on a fine vegetable flour enhanced with our world leading supplement NUTROBAL and its superfine calcium. This has been a roaring success and has resulted in increg calcium levels in crickets by MORE THAN TENFOLD ie x 10, and in mealworms MORE THAN SEVEN FOLD ie x 7. The tests were carried out by an independent laboratory and impressed even us! The protein level is low enough that the mealworms don't mature too quickly, but more than adequate for support of the feeder insects. Gut loading is useful in increg calcium levels but for belt and braces we still always recommend dusting with Nutrobal as well. BOX CONTAINS 1 x 300g Nutrogrub - gut loading food for insects

The same superfine calcium as nutrobal. Enhanced calcium. Veterinary developed gut loading calcium for live food insects.
