Had a few with mastitis recently, most cured ok with 3-4 tubes ubrolexin. No new cases for 10 days now but the last two which i have treated had 5 and 6 tubes ubrolexin plus metacam; appeared to have cleared it up, quarters still had a small hard 'ball' in but were milking out with no clots so thought they would be ok. This morning both are worse again, one is full of clots the other is harder again. I am thinking i just dry the quarters off now but what do others think? Re treating seems like bad practice.
