Last year we had a calf born that at about a day old became very rigid especially on his rear legs. He lived about 3 months and continued to have stiff joints and very tight and rigid in his movement. I chalked it up to a genetic abnormality and sold the cow to eliminate the problem. This past Saturday we had one born that is exhibiting the same characteristics. I know this cow is squeeky clean! I don't know about the bull. I am now off the genetic thing and leaning toward a vitimin/ mineral problem. It's seems like it is actually painful for the calf to get up or move. Has anyone experienced that and can you tell me what is going on? I will reveal what I am leaning toward after some of you respond. I don't want to lead anyone in a specific direction and I may be totally off track. Any help would be greatly appreciated.
