概要	It is still unclear how animals regulate the ingestion of deficient vitamin C (VC). Our previous behavioral studies using Osteogenic Disorder Shionogi (ODS) rats, which lack the ability to synthesize VC, have shown that the preference for familiar VC solutions is increased in ODS rats after VC deprivation compared to before (Yasuo et al., 2019). However, it is not clear whether VC deficient rats ingest novel VC contained diets selectively. In the present study, we conducted a food choice test in which VC deficient ODS rats were presented with a novel VC contained diet and a VC deficient diet (The ODS rats were naïve to them). The results showed that the novel VC contained diet was ingested more than the VC deficient diet on all experimental days after VC deprivation. These results suggest that the ODS rats may ingest VC during VC deficiency selectively, even if they have never ingested VC solution or VC contained food before VC deficiency.
