BRASILIA, April 25 (Reuters) - Brazil's domestic debt load rose to 1.143 trillion reais ($565.8 billion) in March, up 2 percent from 1.120 trillion reais the previous month, the National Treasury said on Wednesday.

The average maturity of the domestic federal debt rose to 31.88 months from 31.64 months.

Including external debt, Brazil's federal obligations totaled 1.278 trillion reais in March, up 1.4 percent from the previous month. ($1 = 2.02 reais)
