I have a 6 yr old ND doe that freshened monday with quads. 2 I am bottle feeding and 2 are on her. I milked out some colostrum from both teats and udder was even, didn't notice anything abnormal. Yesterday I noticed her udder was slightly uneven and checked the larger side to make sure there wasn't too much pressure, there wasn't. I figured her kids must be favoring one side so this morning brought her on the milk stand to milk out the larger side. I also milked out some of the smaller side and noticed it felt like there was a hard mass in there. It was very odd feeling, because I could move the hard part a little so it wasn't like the entire side was hard and tight. She is still producing milk on that side with no clots or anything abnormal. I have several years of neg. CAE tests on her. I have not yet taken her temp although she is eating and acting completely normal. I have never ran across this before. Could it possibly be mastitis? There did not seem to be any heat in it and didn't seem to be at all painful to her.
