I need some advise about mastitis. Almost every goat we have or have had has gotten mastitis. This year no different. Our doe started showing little clumps in her milk, almost too small to see. Called our normal goat vet she said it happens when they start milking heavy (she is producing between 11 and 12 pounds a day first freshening 40 days in). So, called our emergency vet they said same thing. I didn't believe them but, 2 vets saying the same thing, well ok. Well yesterday found a speck of blood, now I truly believe mastitis, so we sent out some milk to be cultured. But, my question is why every goat does this to us? We keep pens clean, cleaning at least every 2 weeks, but make sure there isn't any exposed "dirty" areas in between. Have been cleaning udders before milking, making sure nothing dirty comes in contact with the udder, and use fight bac after every milking. Hay and grain are free from mold. But, for some reason we get mastitis. Is it possible to be hereditary? This does mom got mastitis, but she produced between 15 and 18 pounds of milk a day regularly, and developed a pendulous udder and thought it was from possible injury to her udder. But still other does without pendulous udders got mastitis too. Also wondered if it is possible if mastitis could stay in a barn? The barn our goats are in waqs an old cow dairy, but wasn't used for at least 12 years before our first milking goat came. I'm about at my wits end, we can't seem to keep a clean doe. Any advise or possible things I'm doing wrong? Please help.
