Documentary researcher - pig large intestine as a probiotic

Hi,
I am doing research for a documentary and I would love to speak with someone who has experience using pig large intestine as a probiotic.
I understand it's a controversial topic, and I will treat all conversations with confidentiality and respect.
I'm happy to answer any questions or discuss any concerns you have about speaking with me.
