Oral Deworming Options

I have 4 butcher hogs that I need to figure out the deworming options for. In our area, lots of people do the injectable Ivermectin, or the pelleted options. We have a lot of fair kids that use the Safeguard equine dewormer and give that orally. I have done that once, and wanted to know if I should deworm again, with something different? I would really prefer to do the oral option. I don't feel too confident giving the injection and the pelleted option is not going to work because I do not have a way to separate my hogs. If I should deworm again, can I give Ivermectin orally by using the equine paste? Thanks! Just not too sure on what the deworming schedule should be like for hogs.
