Resumen:
Increasing polyunsaturated or long-chain fatty acids in meat for human consumption improves both nutritional quality and consumer perception. The increase could occur through the addition of rich sources of omega-3 fatty acids (such as flaxseed or flaxseedoil) to the animal diet. The aim of this study was to evaluate the effects of dietary supplement with two presentations of flaxseed (crushed seeds or oil) on the change of FA content in two cuts of caiman meat (tail and neck). We measured fatty profile in two different caiman meat cuts (neck and tail) from 30 animals (total length 96.7 ± 4.9 cm, Response to Reviewer Commentssnout-vent length 47.8 ± 3 cm, weight 4.2 ± 0.6 kg), raised in individual enclosures, fed three a week for 50 days with: crushed chicken head and a dry food formulated for these reptiles in a 70/30 ratio (C, n=10), control diet with 10% crushed flaxseed (FS, n=10), and control diet with 10% flaxseed oil (FO, n=10), while the remaining days animals were fed the control diet. Meats from animals fed both enrichment diet (FS and FO) showed an increase of C18:3n-3 and ΣUFA respect to control diet. Although both enriched diets raised the levels of C18:3n-3, the neck showed higher values than the tail. We observed that the neck, is more susceptible that the tail to be improved by FO, which could suggest that it is more beneficial to consume neck meat. In order to be implemented in caiman farms, flaxseed oil is more expensive than seed, but more effective, easier to manage and is practical for application on caiman farms.
