  We use the semi-classical Boltzmann equation to investigate transport
properties such as electrical resistivity, thermal resistivity, thermopower,
and the Peltier coefficient of disordered metals close to an antiferromagnetic
quantum phase transition. In the quantum Griffiths phase, the electrons are
scattered by spin-fluctuations in the rare regions. This leads to singular
temperature dependencies not just at the quantum critical point, but in the
entire Griffiths phase. We show that the resulting non-universal power-laws in
transport properties are controlled by the same Griffiths exponent $\lambda$
which governs the thermodynamics. $\lambda$ takes the value zero at the quantum
critical point and increases throughout the Griffiths phase. We also study some
of the "universal" ratios commonly used to characterize Fermi-liquid behavior.
