First of all,
Welcome to Predator Masters. We are glad to have you here.
Now for your question. Javalina's will respond to the distress calls of their young very readily. As far as which call you need to use it is really up to you. I have Javalina calls and other calls with enclosed reeds. They are EXACTLY the same call. Reeds are the same and the bodies are the same. Use what you already have and go kill some Javo's.
