Principal causes of claw diseases are lack of keratinization-stimulating substances in feed, elevated humidity, aggressive alkaline environment in stalls, damage of horn capsule and soft tissues of extremities, adynamia and insufficient physical exercise, and also large-scale introduction of highly specialised dairy breeds of cattle with weak claw horn.

Properties of the products Novyrate®C and Lumance® surpass those of unprotected sodium butyrate, and as broiler growth factors and productivity stimulators they are identical to a feed antibiotic. Experts recommend including Novyrate®C and Lumance® in diet as they serve as an effective alternative to bacteriostatic products.
