A retrospective study evaluating vitamin E supplementation in pelicans and plasma alpha-tocopherol concentrations in pelicans, storks, and flamingos

A retrospective study was conducted to evaluate the effectiveness of two vitamin E supplement forms in pink-backed pelicans (Pelecanus rufescens). The forms were a paste supplying 100 IU vitamin E daily or a capsule supplying 10.5 IU vitamin E daily. Baseline blood alpha-tocopherol concentrations were 7.15 ug/ml in 1998. After 10 months receiving vitamin E in the capsule form, the...

Limitations of Plasma or Serum Analysis in Assessing Vitamin E Status of Domestic and Wild Animals

Venipuncture is a relatively noninvasive means of sampling tissues for determination of deviations from physiologic norms. To the extent that norms can be defined and deviations from norms can be associated with abnormality, blood analyses may be medically useful. However, studies of vitamin E metabolism have shown that neither the magnitude of body stores nor the availability of dietary supplies...
