Impact of dietary n-3 and n-6 PUFA on oxidative status and inflammation in yellow-rumped warblers

The intake and ratio of the essential fatty acid classes, n-3 and n-6 polyunsaturated fatty acids (PUFA), impact animal health. The dietary ratio of these fatty acids can be important as n-3 PUFA are considered anti-inflammatory, while n-6 PUFA are pro-inflammatory. Additionally, the increased number of double bonds in PUFA makes them more vulnerable to oxidative damage, potentially increasing the...

Fatty acid status of free-ranging and captive black rhinoceros (Diceros bicornis): correlation to the use of grain-based products

It has been suspected that the fatty acid (FA) status of captive black rhinoceroses (Diceros bicornis) differs drastically from their free-ranging conspecifics, due to the difference in FA pattern between the natural forage and the captive diet. Natural forage of black rhinoceros, and temperate browse, contains a n-6/n-3 FA ratio (expressed as % of total FA) of 0.1-0.3. In contrast,...

Fatty acid status of free-ranging and captive wildlife – a literature survey

In human nutrition, the discrepancy between the fatty acid (FA) status of people from “original” and “civilised” living conditions is interpreted as a major contributing factor to “civilisation-related” diseases. People from “civilised” living conditions are often characterised by a low status of polyunsaturated fatty acids (PUFA), particularly of n-3 PUFA, and a low unsaturation index (UI); the proportion of n-6...

Serum fatty acids concentrations in free-ranging and captive giraffe (Giraffa Camelopardalis)

Serum concentrations of fatty acids in captive giraffes were compared to values obtained from free-ranging giraffes in an effort to identify potential nutritional differences in the captive population. Captive giraffes have a specific set of maladies, including peracute mortality, energy malnutrition, pancreatic disease, urolithiasis, hoof disease, and severe intestinal parasitism that may be nutritionally related. Serum samples from 20 captive...

Nutritional status in captive Bottlenose Dolphins (Tursiops truncates)

Nutritional status of captive dolphins (Tursiops truncatus) was examined using biochemical analysis. Voluntary blood samples, obtained from four healthy captive bottlenose dolphins at Brookfield Zoo, were analyzed for vitamin D metabolites [25(OH)D and 1,25(OH)2D], lipids (total cholesterol, triacylglycerides, HDL-cholesterol, and LDL-cholesterol), and fatty acids. Fish fed to these dolphins were analyzed for dry matter, crude protein, fat, energy, vitamin D,...

Effect of diet on body composition and growth parameters in juvenile seahorses (Hippocampus spp.) at the Toronto Zoo

To date, all information on the feeding of seahorses (Hippocampus spp.) is contained in fish hobbyist magazines emphasizing acceptance of feed rather than its nutritive value. The juvenile stage is most critical in seahorse development and the most problematic in terms of feeding. This study compared the effects of two typical diets, Neomysis integer and Mysis relicta, on the body...
