Took in a 5yo jersey that calved in early september. I looked at this cow in late august and she was a beatiful healthy cow, perhaps even a little hefty. some new to cows people bought her before I decided if I wanted to spend the $$$ on her. long story short, they haven't really been milking her except when they need a little milk and the cows been nursing her calf. other than that I know nothing about what happened between august and now. picked her up 5 days ago, she looks like shes starving to death. skinniest cow I've seen in person. started her on grass hay thats about 25% timothy and lots of alfalfa with little grain. shes producing more just on the few days even though we haven't been milking her out all the way hoping shed put weight on rather than kill herself making milk. lastnight went out and she was down. finally got her up. gave her some cmpk just in case it was milk fever related. milked her, turned her back out. never really showed any signs of milk fever. tonight, down again. can't get her up. the couple of times she tried, she couldn't get her legs under her for what appears lack of strength. do we give her time? do we hoist her up? shes ben down around 5yo hours at this point. we've got a "blizzard" coming in tonight/tomorrow. she at least lated down in the barn but has no water. I'm no dairy expert but have several other jerseys. never had a rescue cow before. would really like to save her if at all possible. she was such a nice cow. sorry for all the typos... my "smart" phone isn't nearly as smart as it thinks it is.
