What is a good pulsation? I noticed recently at a show that my new milk machine (also my first) seems to be running way slower than the folks around me. I have been hand milking and now started using the milk machine....all of a sudden I have two lopsided does out of 7. I am running milk cultures to our state vets office in the AM to check out the smaller sides...but, after reading this have to wonder if my new machine has contributed???Kaye White said::biggrin Yeah, even I get mastitis...but I attributed it to my fluctuation in the old vacuum pump I had and milking with too slow a pulsation.
