Maternal influences on ontogeny of suckling and feeding rhythms in the rat
Abstract
To assess the effects of both maternal and endogenous factors on the ontogeny of nocturnal feeding in the rat, day and night weight gain was determined in the sighted or blind litters of sighted or blind litters of sighted or blind dams and in young weaned at 15 days of age. Sighted dams impose a diurnal milk-intake pattern on their young. The nocturnal pattern of solid-food intake begins at 19 days of age. Blind litters also display nocturnal feeding when kept with sighted dams, but only until 35 days of age.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
