METABOLIC CONSEQUENCES OF THE EARLY ONSET OF OBESITY IN COMMON MARMOSET MONKEYS.

We examined the patterns of fat mass gain from birth to 12 months in common marmosets (Callithrix jacchus), and tested the hypotheses that juvenile marmosets with excess adipose tissue will display higher fasting glucose, decreased insulin sensitivity, and decreased ability to clear glucose from the blood stream. Lean and fat mass was measured by quantitative magnetic resonance at 1, 2,...

Influence of diet and time on fat and retinol concentrations in adult feeder crickets

Many captive amphibians are fed supplemented crickets (Acheta domesticus) as a basal diet. There is concern that some amphibians have unique requirements for certain vitamins, particularly vitamin A due to its association with squamous metaplasia of mucous producing epithelia, resulting in inability to capture prey. Because vitamin A is fat soluble, it was hypothesized that increasing fat concentration of crickets...

Age Changes in Digestibility of Nutrients in Ostriches

Age Changes in Digestibility of Nutrients in Ostriches Roselina Angel Purina Mills Inc., St. Louis, Missouri A digestibility study was conducted with 3-, 6-, 10-, and 17- week old and 30 month old ostriches. Two methods were used to determine digestibility: the total excreta collection method and a marker method, using chromic oxide. No significant difference between methods used to...
