The results of the measurements of temperature dependence of the electrical resistivity ρ(T), thermal expansion L(T) and susceptibility χ(T) on single crystal DyNi_{5} in the temperature range 4.2-300 K are reported. The maximum in ρ(T) at T_{N}=12.2 K was observed which corresponds to the transition to antiferromagnetically ordered state. Taking into account the Bloch-Grüneisen formula for electron-phonon contribution ρ_{ph}(T) to ρ(T) the anisotropic magnetic contribution ρ_{mag}(T) was determined. We also observed the anisotropic behaviour of L(T) at low temperatures.
