I am on round 2 with some goats, 3 with some and want to do round 4 with others, of LA200 for the problems that I have posted about in earlier threads. They are responding well to it, no more abortions, runny noses and coughing going away. Some still a little under the weather, but getting well. I called several local feedstores within reasonable driving distance and none had off-brand tetracycline inj. They only had LA200 which i know is a more painful injection. I have given it subQ and have been giving it carefully, on different sides behind front leg, tenting skin well up with no difficulty at time of injection. They show no distress at the time and seem to maybe have a bit of a sting as they are led back to their pens. The trouble comes the next day when they are sore and limpy and seem miserable with it. The first 2 inj. with some, was on the same side...then when i alternated sides, both sides are sore and they look pitiful like they don't want to walk and if they do, it is like it is very very painful. It is very noticeable. Is this the norm? I feel terrible about it. Am I wrong in giving it behind from elbow? I give it about 3 inches or away, not right behind it, and it also depends on where i can grab a good handful of loose skin, each goat a bit different than the other.
