t: In Santa Fe (Argentina) Proyecto Yacaré is a program based on ranching(collection of Caiman latirostris eggs from wild populations for farming of hatchlings).Ten percent of the hatched animals are reintroduced into the same harvesting areas,and ninety percent is used for leather and meat production; until today lipid depositsof the carcass are discarded. Previous studies reported enrichment of caiman meatwhen ground flaxseed is included in the regular diet. For this reason, our work aims toassess whether the addition of flaxseed to the diet (considered a powerful antioxidant)also improves fat quality, delaying deterioration and extending fat integrity. In orderto do so we grew during 30 and 60 days caimans of slaughtering size. Animals were fedad libitum six times a week with the control diet (crashed chicken head + dry balancedsupplement 70/30) (C30 and C60), and control diet + ground flaxseed (90/10) (FS30 andFS60). After the experiment we removed fat deposits and determined catalase andglutathione peroxidase activity, lipoperoxidation (LPO), and oxygen reactive species(ORSs). Flaxseed addition in diet increased antioxidant enzymes activity, and reducedlipidical peroxides and ORSs in both groups fed with flaxseed but in FS60 there wasa greater decrease in LPO and ORSs compared to the other groups. Based on ourresults, we corroborated the antioxidant capability of the diet with flaxseed, increasingquality duration and integrity of fatty tis
