Coprophagy is important for the nutritional balance of _________.
prohojiy [21]

Coprophagy is important for the nutritional balance of rabbits and their relatives.

The behaviors of the rabbit, rat, mouse, hamster, guinea pig and chinchilla have all been linked to coprophagy, which is the act of an animal re-consuming its own discharged excrement. Cecotrophy is a better name for it.

The omnivorous rats, mice, and hamster display cecotrophy to a lesser level than herbivores' hindgut fermenters like the rabbit, guinea pig, and chinchilla. In order to boost the supply of folic acid and vitamin B12, it may rise during pregnancy and lactation.

Coprophagy is an intrinsic behavior triggered by the reflex, despite the fact that modern diets make it unnecessary for survival.
