This is purely my opinion and there are some people who will HIGHLY disagree with me.
I think with a small herd that is being sold at sale barns (primarily kill market) that vaccinating all your animals and separating any with active abscesses is an acceptable way to handle it. Any new animals you bring in should be vaccinated and isolated for 30 days in different isolation area than the one used for abscess animals. The study I read said the vaccine is about 80% effective. If you keep everything clean and be careful with infected animals you will reduce the incidence considerably.
If you sell any at other than a sale barn let the buyer know you have CL in your herd and how you are managing it. When you visit other farms wear shoes and clothing you do not wear in your barn or when working with your animals.
CL and other infectious diseases is the primary reason not to buy at sale barns. The animals there are others rejects, sick and problem animals. Do some research and ask around, there are lots of places in TN to get decent market animals. Buy directly from the producer.
Do you have any other goats than the one you just purchased? Goats have different nutritional needs than sheep and she will need to be fed separately. Goats need copper and copper kills sheep. All-stock feed and mineral is not sufficient for goats.
I too am an animal lover but I grew up on a farm so it is easier for me. I see it this way- animals are eaten, that is what our bodies are intended to eat. The animals I raise may have short lives, but they are good lives. If more animal lovers raise food animals, fewer food animals will have miserable lives on factory farms.
Be careful, CL bacteria can cause a skin infection in humans. Most importantly, enjoy your farm!
