Conteúdo: | The study was carried out to evaluate the growth rate of broad-nosed caiman, Caiman latirostris hatchlings, fed on four animal protein diets: (a) dead poultry from a poultry farm; (b) dead piglet from nursery and farrowing house is a swine farm; (c) whole tilapia (Tilapia rendalli e Oreochromis niloticus); and (d) a balance mixture of a, b and c sources. Sixteen seven-month old caimans, average weight of 208 g and, 38 cm of total lenght (TL) were distributed in four treatments. Four groups of four caimans easch were placed in cement enclosures inside a greenhouse. Diets were supplied at the average rate of 97.8% +- 34.8% of the body weight per week (average and standard deviation; wet weight basis). Body mass and total lenght of caimans were measured every 30 days dor six months (Nov. 1995-April.1966). An analysis of variance with repeated measures was performed. Diets provide suitable growth for weight and TL (mean +- standard deviation, respectively): (a) 2,157 +- 743 g and 79.5 +- 6.9 cm; (b) 1,811 +- 222 g and 75.7 +- 1.9 cm; (c) 2,431 +- 780 g and 80.7 +- 5.8 cm; (d) 1,683.5 +- 736 g and 74.5 +- 7.2 cm. There was no significant effect of diet on weight, but diet effect on TL of hatchlings approached significance (p<0.10). It is concluded that all diets have good potential, in growth sense, to be used in commercial farms or ranches and for captivity propagation programs of caimans.
