Pull ServiceName attribute from another class in the Agenda view using the foreign key ServiceID with Razor Asp.Net mvc

I have a Index view that lists the schedules.

In this list the calendar attributes include a foreign key IDServico , however, the list only appears the IDServico index and needs to appear the Service Name .

The code that displays the index looks like this:

@foreach (var item in Model) 
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.AutorizacaoAgenda)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Data)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Hora)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Disponibilidade)
        </td>
        @*Aqui é o código para mostrar o IDServico*@
        <td>
            **@Html.DisplayFor(modelItem => item.IDServico)**
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id=item.ID }) |
            @Html.ActionLink("Details", "Details", new { id=item.ID }) |
            @Html.ActionLink("Delete", "Delete", new { id=item.ID })
        </td>
    </tr>
}

My Controller looks like this:

using System.Collections.Generic;

using System.Data.Entity;
using System.Linq;
using System.Net;

using System.Web.Mvc;

            ViewBag.IDServico = new SelectList(db.Servicos, "ID", "Nome");
            return View(agendas);
