Joint ill is one of the toughest to treat in calves. If you are using pen...toss it in the bush. Hit with Excede or what ever they recommended in the link above. We use nuflor and an anti inflam. Normal treatments can take over a week sometimes two with it in the joints. Nuflor has an IM and SQ dosage. We go with the IM because it is every two days and the other is longer 4 days i think...read the label.
Do not stop treating just cause you think it will be ok. At that point, where the calf is doing well and on its way to recovery, give the last dose the longer acting
With this tough bug, always err on the side of caution. If it re occurs it will be even worse
And yes, if conditions are ripe, navel ill can start just after birth. The wet navel acts like a sponge and soaks the bacteria into the liver. Once there, it will go septic and procede to the joints. We had one calf that went septic within less than 24 hours from birth, and ended up with a brain infection 24 hours later...encephylitis (sp). We started agressively with treatmens at the 12 hour mark from birth, but it was fast.
He is a last spring (2011) calf. He is alive and being grassed this summer and then butcherd. The steer is small, about the size of a 6 month old...and slobbers like no bodies business. Hubby named him "slobber pants"
