I have NO idea why she got mastitis. Cher, my milk doe that I just started trying to dry up a couple weeks before Christmas now has Mastitis in her right side. I noticed for a couple days she seemed a little painful and today I squeezed to see if I could relieve some pressure on that side as she is still bagged up and sure enough, chunky, like thin cottage cheese. Not much. I just milked her out completely on both sides, as the left side was really tight too and I didn't want to take a chance that there might be mastitis there too. It did not appear to. I gave her 3cc Pen. Procaine G (all I had on Christmas Day). She is running fever and I have put one of my big, long tail sweatshirts on her which she seemed to really appreciate, to keep her from getting too chilled. Am I giving her the right penicillin? What do I need to get to infuse in her infected udder? SHould I go ahead and treat both sides just for good measure? and....WHY did this happen. The last day I milked her out she was fine. I washed her before I milked and I sprayed afterwards like I always did. I have not had a problem with her at all this summer. But...now that I am trying to dry her up she gets Mastitis. :no: She is also still thin. I thought once I quit milking her she would possibly put on a little weight, but she hasn't and I did get some BOSS and added to the alfalfa pellets that I am feeding them along with fresh coastal hay. Anything else I need to be doing for her?
