We have a Gotland ewe, Betsy. In her first year of lambing triplets (2009) with us she developed mastitis in her left quarter. We had the vet insert an antibiotic straw, gave her further injections as directed and stripped the quarter of the 'cheese' a few times every day until she was empty. She kept the quarter as a result, but we gave her a break from lambing the following year to fully recover. In 2011 she produced a fine set of twins and, to our delight, both udders were sound and milk was produced for both lambs. Betsy has just given birth to another set of twins tonight, very quietly bless her without any fuss (she just gets on with it - the advantages of experienced ewes) and I've found whilst the right side is soft and produces milk, the left is hard, slightly lumpy and NOTHING comes out. She patiently let us try so it doesn't hurt her. It feels the same temperature as it's partner (not hot/not cold) and is not a dodgy colour (had a ewe with gangrene last year and the udder was removed, so I know the blackness and cold to look for). I will call the vet tomorrow and I've fed the babies the powdered colostrum to be on the safe side but I wonder if any of you have any advice and experience to share on the matter. It would be much appreciated. I don't want to have missed something obvious or find out I could've done something.
