Well.. Around here, and I'm sure in a lot of other places, people who raise meat goats aren't terribly concerned about the health of their herds so long as they're not losing a ton of animals from an outbreak of something acute.. That's fine, I guess...I don't operate that way, but to each their own.
What I wish they realized, though, is that CL is still an economic problem for them. CL affects carcass quality, which affects their bottom line at the market. If not for the presence of CL in such a high percentage of meat goat operations, I personally believe the market price for all slaughter goats would be much higher.
It's also an economic problem in dairy goats. Since CL is a zoonotic disease, meaning that humans can be infected with it, there aren't many people who are willing to purchase a known CL+ goat to provide their family with fresh milk to drink. Having uncontrolled CL in a dairy herd makes it basically impossible to sell kids.
Now...if you go beyond the dollars and cents and risk to humans and actually consider the welfare of the animal, it's important to understand that CL doesn't only manifest itself as knots under the skin. A goat can get CL abscesses on its internal organs, and they often affect the lungs, liver, heart...sometimes even the spinal cord and other organs. Ill-thrift sets in, pneumonia, downers..
Make no mistake...goats die from CL. It absolutely is a terminal disease.
Here's the thing...I truly believe CL could be all but eradicated if people would only spend $0.50/head on Case-Bac. That's economical for anyone -- I don't care how big or small your herd is.
To me, that's probably the most frustrating thing about it.
