He met with factory manager, Martin Reupp, before taking part in a question and answer session.
This was followed by a tour of the factory, which employs 643 workers. The potential to use green energy was discussed.
Mr Barclay said: “It was a very interesting visit. Nestlé Purina is one of the area’s main employers and I was impressed to see how much they have invested and the rapid growth they have enjoyed over the recent year.”
