What causes plugs in teats? I have one doe that seems to be having this alot this year. She's had them in the past. She has a baby on her 24/7 plus me milking, so I would think it would stay clear. This morning she had one that was very difficult to dislodge. It looks like a little white curd with a tiny bit of blood on it. No fever, no lumpiness or heat in the udder, no stringiness in the milk. Should I be looking toward mastitis or could this be dietary - like two much protein? She's a month fresh.
