  The resistivity, magnetoresistance and in-field heat capacity measurements
were performed on GdPt$_{2}$ intermetallic compound. The magnetocaloric
parameters $\Delta T_{ad}$ and $-\Delta S$ were derived from the in-field heat
capacity data. Comparison has been made between the magnetocaloric effect
$-\Delta S$ and difference in resistivity $-\Delta \rho$ $(=\rho(H)-\rho(0))$
as a function of temperature. There is distinct difference in the temperature
dependence of $-\Delta S$ and $-\Delta \rho$ below the ferromagnetic transition
temperature. However after removing the domain wall contribution from $-\Delta
\rho$, the nature of $-\Delta S$ and $-\Delta \rho$ dependence as a function of
temperature are similar. Our observation indicates that the domain wall
contribution in magnetocaloric effect is negligible in spite of the fact that
it has significant contribution in magnetotransport.
