Alteration in fatty acid profile in rainbow trout (Oncorhynchus mykiss) following the diet supplemented with clinoptilolite

Popis výsledku v původním jazyce

The goal of this study was to investigate the effect of clinoptilolite as a feed supplement the fatty acid profile of rainbow trout muscle. A total of 180 rainbow trout were placed in twelve tanks of the volume of 160 l (15 fish in each). The duration of the experiment was 51 days. The industrially produced granular feed Biomar EFICO Enviro 920 Advance 4.5 mm was used as a base for the feed mixture. The clinoptilolite was mixed with commercial trout feed in five different rates (1%, 2%, 3%, 4% and 6%). The control group was without the addition of clinoptilolite. Lipids for determination of the fatty acid profile were extracted with methanol-chloroform solution according to Folch et al. (1957). The lipid analysis of muscle samples was performed individually from six fish in each group. We found significant differences in the fatty acid content of fish muscles, but no differences in the relative fatty acid content were confirmed. In general, the addition of 3% clinoptilolite was different from other treatments and controls. The lowest n-3/n-6 fatty acid ratio was found in the control, while the addition of clinoptilolite increased this ratio. For human nutrition, fish is indispensable as a valuable source of quality animal protein and fat. Fish fat is a rich in n-3 and n-6 fatty acids. The composition of the fatty acid groups depends on the diet, age or environmental conditions. The composition of fatty acid spectrum in fish can be adjusted by special diet with some additives such as clinoptilolite.
