Maize-based diets, even when supplemented with protein-rich items such as earthworms, are responsible of important maternal infanticides in the endangered European hamster (Cricetus cricetus) owing to a major deficiency in vitamin B3. A supplementation of this vitamin suppresses maternal infanticides and restores a proper reproductive success (the picture is showing a female hamster eating an earthworm). See the paper ‘Diets derived from maize monoculture cause maternal infanticides in the endangered European hamster due to a vitamin B3 deficiency’ by Tissier et al, published in Proceedings B (http://dx.doi.org/10.1098/rspb.2016.2168)
