We've an old oxford sow, she was one of our first pigs, and grandmother to one of our breeding sows, we'd kept her for sentimental reasons, however this morning was really lame on her front trotters, walking round (quite happily on her knees!) i've cleaned them up (not really bad) and sprayed them with foot master, but i think its more likely her huge size, she must be the size of a shetland pony well over 400kg. now we occasionally have had lameness before when there run goes from hard dry to wet, which is whats happened. now i'll keep her in now on deep straw and in till hopefully it clears up with some spray and medication but is this cos of her size putting pressure on her feet... do we sausage her???
