Modern Trends in Swine Production-1961

The pastures and bigger lots seen later in the film are closer to what I remember. Some of the sights and all of the sounds match recollection.

Esp. the muted grunts and slamming feeder lids in this section and this one.

And the US Steel logo that appears is very familiar.
