Resumo: | Cost of feeding is the main limiting factor of caiman farming. The use of livestock discards and byproducts as food sources in caiman farms might help solving this problem. On the present study, four different livestock discards were evaluated as food for broad-snouted caimans (Caiman latirostris) on the first year of life. A total number of 120 hatchlings from six different clutches were kept in four tanks inside a greenhouse. The following diets were used: fish, swine, chicken, mixed (fish + swine + chicken, equal proportions). The experimental design was based on nested ANOVA. Weight gain and growth rates of snout-vent length and belly-width were measured and growth models established. The mixed diet resulted in best growth rates and weight gain, but no consistent difference in growth models among diets were detected. |

O custo da alimentação é o principal fator limitante para a criação de jacarés em cativeiro. O uso de descartes e subprodutos como fontes de alimento em fazendas de criação de jacarés poderá auxiliar a resolver este problema. No presente estudo, quatro diferentes tipos de descartes provenientes da produção animal foram avaliados como alimento para o jacaré-de-papo-amarelo (Caiman latirostris) durante o primeiro ano de vida. Um total de 120 filhotes provenientes de seis ninhadas foram mantidos em quatro diferentes tanques dentro de uma estufa plástica. As seguintes dietas foram usadas: peixe, suino, frango e mista (peixe + suino + frango em iguais proporções). O delineamento experimental foi de ANOVA por blocos. Ganho de peso e taxas de crescimento do comprimento rostro-anal e da cintura comercial foram medidos e modelos de crescimento foram estabelecidos. A dieta mista resultou em melhores taxas de crescimento e ganho de peso, mas não foram detectadas diferenças consistentes entre as dietas usadas quanto aos modelos de crescimento.
