Ok we have this calf who just turned 6 months, she was about to be weaned. She was fine yesterday, was running around. But today we woke up and her dam was bellowing, so we went out to find her and she was laying flat an couldn't stand up, so we got her in the trailer and took her up to the vet, the vet said she had swelling through her brisket and underline, and her temperature was too low. He said that he thought it might be blackleg? But from what I am finding it doesn't look like black leg to me. Any ideas?
