Sows

The summary of an extension post on farrowing and nursing facilities:
The decision regarding space allocation pits the biology of the pig against the economics of production systems. Since each 3% reduction in space allocation for pigs in fully slatted facilities results in only a 1% reduction in daily gain and daily feed intake, producers have historically accepted a reduction in individual pig performance in order to maximize economic returns from investments in facilities. Based on the recommended codes of practice from the European Economic Community and Canada, there is no agreed upon standard for space allocation in the world community. In the future, considerations such as welfare codes and response of the market chain may change the space allocation decision.
If I recall, Florida put some sort of restriction on farrowing pens. I'm rather of two minds on this, and similar animal welfare issue. On the one hand there's a power imbalance between the animal grower and the animals.  One of my rules is based on Lord Acton: power corrupts.  Granted over the long haul it's in the interest of the grower to treat her animals humanely, but so is it in the interest of employers to treat employees well.  We know neither happens in every case.  On the other hand, there's definite economic tradeoffs, as shown by this study.  The bottom line, as society gets wealthier we can afford to put some of the wealth to better treatment of animals as opposed, say, to more square footage for the home.
