Resumen:	The magnetic and magnetocaloric properties of Nd5Si1.45Ge2.55 compound has been studied under high hydrostatic pressure up to 0.9 GPa. At ambient pressure, the Curie temperature (TC) and magnetocaloric effect (MCE) give values TC=58.1 K and-Δ SM=4.9 J/kg K. Both TC and MCE weakly increase with pressure. Using the value of compressibility (1.7*10-2 GPa-1), we showed that the values of dTC/d V and d\|-Δ SM\|/d V obtained from experiments under high pressure are sufficiently lower than those estimated from the x-dependence of the lattice cell volume of Nd5(SixGe1-x)4 compounds. It indicated that the changes of magnetocaloric properties cannot be explained only by volume effect.
