Pig Classifications
I still remember the first time I called to inquire about purchasing feeder pigs from a local farmer. “Are you interested in gilts or barrows?” She asked me. I had absolutely no idea what she was talking about and sheepishly asked what she meant by that. I want to help other clueless homesteaders avoid embarrassment. So, I have put together a list of commonly used terms in the world of pig farming.
Baconer – a finished pig ready for market typically weighing between 150-300lbs.
Barrow – a male pig that was castrated before reaching sexual maturity.
Dam – the female parent.
