Effect of lutein supplementation on blood carotenoids and vitamins in a variety of marine mammals

Lutein, an oxygenated carotenoid concentrated in the retina in a variety of species, may enhance ocular health (Mares-Perlman et al., 2002). Given the high incidence of ocular pathology in captive marine mammals (Dunn et al., 1996), it was hypothesized that a lutein supplement may protect against some of these conditions. This trial examined the response of different marine mammals to...

Effect of dietary nutrient level and source on feeder mouse nutrient composition

Whole prey items may contain lower nutrient levels than desired for feeding exotic carnivores. The purpose of this trial was to gather preliminary data on the effect of different dietary treatments on the nutrient composition of mice at various ages. Dietary enrichment with vitamin E and chelated minerals in general did not improve total body levels of most nutrients, but...
