A study was conducted to find out the effects of feeding signal grass (Brachiaria decumbens) on the levels of AST [Serum aspartate aminotransferase], ALT [serum alanine aminotransferase] and SAP [serum alkaline phosphatase] of sheep. Six male lambs were used in the study, three of which were fed with signal grass and the other three were fed with paragrass, ad libitum. Levels of AST, ALT and SAP levels were determined for three weeks interval using commercially available kits using Colorimetric method. Levels of AST, ALT and SAP showed a remarkable increase on the animals fed with signal grass. A continuous rise on the levels of serum enzymes were observed from the first week up to the third week of the study. The initial mean AST level was 54.40 IU/L, and three weeks after feeding signal grass, the mean AST level was 68.12. The initial ALT level obtained was 29.75 IU/L and after three weeks of feeding signal grass, the mean ALT level was 34.14 IU/L. The mean SAP level of the sheep before feeding signal grass was 35.73 IU/L. After three weeks of feeding signal grass, the mean SAP level was 73.52 IU/L
