< Ear notching tells the producer which litter the pig was born to. The tool they use ,( pictured here ) is like a pair of scissors with razor blades .. No they do not be nice to the little pigs when they do this none of this is nice and of course no sedation either ... just a screaming baby grabbed and held screaming while they slice his little baby ears . If you eat pigs your eating babies PLEASE STOP EATING BABIES and put an end to this barbaric and cruel industry.
