I don't think the nylon rope is going to work for pigs. They will chew anything they can reach and they would make short work of this rope. You will probably need wire.

Mark I always have handy a roll of plastic coated wire and wire snips handy I attach my garden wire panels to stakes and other things when I really want something secured, but easy to remove and reuse. I also used it to secure tarp around some extra straw bales I didn't want to get wet last year through the winter. It is one of my favorite things - plastic coated wire!! Jayne
