My Nubian, Rayna was bred to kid at a year old. In the last couple weeks of her pregnancy, her udder seemed to be coming in even. In May, she gave birth to twins (wethers), who we left on her. She was a good mom to them and all seemed to be going OK until her twin kidded a couple weeks later. The kids started to nurse off the sister as well as their mom and I noticed Rayna's udder starting to become uneven. I thought they were just sucking more off the small side , so didn't worry at first. When I thought I should test her, the small side turned the mastitis indicator greenish, so I treated her with Today. After completing the two dose treatment, her milk still wasn't coming back in that side like it should. I called my vet and he said it probably wasn't mastitis because the milk looked normal and the udder wasn't swollen, red or hot to the touch. He said to be on the safe side to do the Today for a few more days and to give her Nuflor shots as well. I did that and her milk never came back in. He thinks she probably has a problem with the gland in that side. The one side dried up and she made as much milk on her good side as her twin gave on both sides. She is now bred again to kid in March. I'm wondering if this is something her doe kids could inherit. I've never seen this before in a goat who didn't have real obvious mastitis. Have any of you had this show up in your herd?
