| Resumen en inglés | The aim of this article was to evaluate the effects of 17-a-methyl-testosterone on some morphometric indexes in bullfrog (Rana catesbeiana). For that purpose, 120 animals with an initial weigth of 42.052 ± 0.528 g were distributed in four 1,54m2 confinements, and fed "ad libitum" with rations containing 44% of crude protein and incorporated with different concentration of the androgen: 0, 20, 40, and 60 mg/kg, respectively. The hepato-somatic index was calculated using the relation HSI = Wf/WT, where Wf was liver weight and Wt was total weight, and the lipo-somatic index was calculated by the expression LSI = WL/Wt, where Wl was visceral fat. It was observed that the hormone did not have an effect in the hepatossomátic and lipossomátic indexes |
| Resumen en portugués | Objetivou-se por meio deste trabalho avaliar o efeito do androgeno 17-a-testosterona nos indices morfometricos de ras-touro. Foram utilizados 120 animais com biomassa final de 42,05 ± 0,528 g e estes foram alimentados ad libitum com ração comercial contendo 44 % de PB o qual foi incorporado o andrógeno em diferentes concentrações T1-0mg/kg, T2-20mg/kg, T3- 40mg/kg, T4-60mg/kg. O indice hepatossomatico foi calculado pela formula IHS = Wf/WT, onde Wf= peso do fígado e Wt = peso total e o indice lipo-somaticos ILS=WL/Wt, onde Wl= gordura celomatica. Observou que nao houve efeito do hormonio nos indices hepatossomatico e lipossomatico |
