Koza, G.A.; Mussart, N.B.; Barboza, N.N.; Coppo, J.A.: Biochemical and morpho- metrical response to the supplementation of fish, chicken and bovine meat in the diet of Cayman yacare captive specimens. Rev. vet. 23: 2, 110-115, 2011. Nutritional biochemical indicators, liveweight and corporal dimensions allow to evaluate the impact of different diets regarding the growth of Caiman yacare, as well as to optimize their commercial breeding. In a hatchery located in northeast Argentina, three diets were evaluated using 60 sub-adults specimens (liveweigh: 1.46 ± 0.06 kg and muzzle-sewer longitude: 37.29 ± 0.28 cm), divided in three groups of 20 animals each (50% each sex). All animals received a basal diet (70%) of balanced food (DM 88%, CP 30%, EE 11%, ash 4.5%) and a supplementation (30%) that varied according to the group (bovine meat, chicken or fish). At the beginning and the end of the trial (170 days) weighings and corporal measurements of the reptiles were carried out. Also, blood analysis (nutritional profile) were performed in 10 animals of each group (50% of each sex). Through a totally randomized design, the analysis of the covariance (ANCOVA) was carried out. Parameters such as longitude and head wide, as well as values of total pro-
