We were given a calf at 5 days old, she had been pulled, she was born 3 weeks premature. Have had her to vets, he's given her Selenium, long acting penicillin, and Bentamin 2ml each day for 6 days. We are using the last of the Bentamin today. She can move all her legs, but still doesn't seem to have the strength to stand up, she's nursing well, I am feeding her 4x a day about 4 pints each feeding. We are new to this, and was wondering if there's anything else we should be doing? Also, should we have a sling or something made up to help her have strenth in her legs? I think that her tendons haven't fully developed in the legs. Would appreciate any help I can get, we take her back to the vets on Wednesday for followup.
