Dietary alpha-linolenic acid does not enhance accumulation of omega-3 long-chain polyunsaturated fatty acids in barramundi (Lates calcarifer).

This study examined the effects of substituting fish oil and fish meal with a blend of alpha-linolenic acid (ALA, 18:3 n-3) rich vegetable oils (14%, w/w) and defatted poultry meal (34%, w/w) in a formulated diet, on growth and tissue fatty acid profiles in barramundi fingerlings. Results indicated that on average, while the ALA levels of the barramundi liver and fillet increased with increasin...

Dietary alpha-linolenic acid enhances omega-3 long chain polyunsaturated fatty acid levels in chicken tissues.

The effects of enriching broiler chicken diets with a vegetable source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the accumulation of n-3 long chain polyunsaturated fatty acids (LCPUFA) in chicken meat were investigated. Sixty unsexed one-day-old broiler chickens (Cobb 500) were randomly allocated to one of six diets (n=10 birds/diet) for 4 weeks. The ALA levels varied fro...

Defining essential fatty acid deficiency in juvenile barramundi Lates calcarifer

Barramundi (Lates calcarifer), a catadromous teleost of significant and growing commercial importance, are reported to have limited fatty acid bioconversion capability, typical of marine species, and therefore require preformed long-chain polyunsaturated fatty acids (LC-PUFA) as dietary essential fatty acid (EFA). In this study, the response of juvenile barramundi (47.0 g/fish initial weight) f...

Omega-3 Long Chain Polyunsaturated Fatty Acids as Sensitizing

The efficacy of chemotherapy depends on sensitivity and intrinsic or acquired drug 14 resistance of cancer cells. The n-3 long chain polyunsaturated fatty acids (n-3 LCPUFAs) are 15 considered chemosensitizing agents and revertants of multidrug resistance by pleiotropic 16 mechanisms. The specific mechanisms are not fully understood, but nowadays, it is widely accepted 17 that there are a compl...
