Yes, it's the same and used for the same problems that CMPK is.
Uhh...I got my injectable CMPK through a breeding farm buy-out. I *think* it's a Vet Rx., not sure on that...but mine has the dispensing vet's lable on them.
And you want to use the injectable when your goat is in a crisis...the oral is fine for profilactic use and prevention...like a doe isn't cleaning, she didn't eat her morning meal when heavy bred and not due but is showing no other hypocalcemia sypmtoms...you have her back to normal and kidded with the injectable, and want to give it orally to her until the bottle is gone to make sure she doesn't go into milk fever.
