I went to give my calf a shot of LA200 and noticed it had expired Jan 2005,(the LA200 not the calf). I didn't know if it was still good, so I bought some at the feed store, I didn't have my glasses on and thought it said april 2008. I gave the calf a shot and looked at the bottle again with glasses and it had expired April 2003. Bought another bottle today it expires in 2007. (wore glasses)
Gave it another shot, it lunged and I broke the plunger off,(at least it wasn't the needle) ended up pushing it down with my little finger.
Anyway, I have the calf with the foot that looked similar to Ollies.
Started alternately treating it with diluted Iodine and straight bleach. It looks much better and it is putting weight on it most of the time. I don't know if the expired la200 worked or it was the iodine or just time.
