I find interesting tidbits while browsing around. Things I did not know, and I want to remember:
Nicarbazin is an anticoccidial drug that reduces reproductive performance when it's inadvertentlyadded to layer or breeder diets at normal anticoccidial levels. The yolk membranes are weakened,resulting in mottling of the yolk. Nicarbazin fed to brown-egg layers turns their eggshells white within 48 hours, although this is completely reversible when the product is withdrawnfrom the feed. Even low levels of nicarbazin can cause some loss in shell color, mottlingof egg yolks and a decline in hatchability.
