On the basis of the thermodynamic approach, we report the magnetocaloric properties of the ternary ferromagnetic NdNi_4Si compound with magnetic phase transition temperature T_{C} at 8 K. The saturated magnetic moment in H = 9 T is equal to 1.5 μ_{B}/f.u. at 4.2 K and the compound crystallizes in the hexagonal CaCu_5-type structure (space group P6/mmm). The magnetocaloric effect was calculated in terms of the isothermal magnetic entropy change Δ S_{M} as well as the adiabatic temperature change Δ T_{ad} using the specific heat data and magnetization measurements. Within the second order phase transition significant values of these parameters have been observed.
