1992
DiGiacomo, R.F. | Deeb, B.J. | Anderson, R.J.
Reproductive abnormalities in New Zealand White rabbits at a large commercial rabbitry were linked to an excess of dietary retinyl acetate. Fetal resorptions, abortions, and stillbirths were common in pregnant does. Examination of aborted and stillborn fetuses disclosed hydrocephalus, microencephaly, and cleft palate. Analysis of the commercially prepared feed disclosed a total vitamin A content of 102,278 IU/kg, of which 97,618 IU was retinyl acetate (recommended total vitamin A concentrations are 6,000 to 12,000 IU/kg). Levels of vitamin A in the plasma of does with reproductive disorders were 517 to 1,667 ng/ml (normal level is 300 ng/ml), and liver levels were 2,070 to 12,854 micrograms/g (normal range is 50 to 300 micrograms/g).
