I keep seeing mentions of selenium and copper flushing, gels, blousing, etc...While there are lots of posts regarding these, none answer my questions. The posts all discuss method, where to buy, how to administer, if their goat is due, etc. :? :help: Are these necessary in goats who are fed quality hay, grain, and minerals? I've seen suggestions of doing both selenium and copper twice a year, is that the standard schedule? What are the symptoms that a goat shows when needing copper or selenium? Selenium aids in bone and joint growth and copper aids in cell development especially of organs, skin, and hair. So, while I can't imagine any selenium deficient symptoms until the goats have done without long enough to cause growth problems...copper I would assume would be a dull/wire goat and or dull or dry skin? What is blousing (I've also seen it spelled bolusing)?
