CONCLUSIONSDCAD +40 and -40 and fish oil supplementation decreased dry matter intake, but had no effect on dry matter and organic matter digestibility.

DCAD +40 and -40 indicated were out of the normal range, therefore decreased body weight.

Excess of anion or cation intake were excreted via urine, thereby changed urine pH.
