My 5 yo milking doe, unbred, 8 months into lacation, milking 1x/day was down. Able to get up, but muscles quivering, especially in the hind legs, but front as well. Temp is 100.8 compared to another two doe's who are at 101.9 - 102.1. Peeing, pooping, eating and drinking fine (was eating and drinking this morning - just was her pee and poop). I don't have real CMPK, but a substitute that the vet gave me: Cal-Phos #2 With Potassium by Phoenix Pharmaceutical, Inc. My syringe only goes to 12cc so I gave her two SQ shots of 12cc each. I came back in and did the math and the strength of it appears to be about 1/2 that of CMPK. Do I give her another 2 SQ shots? Wait and watch? When to give again and how much? Anything else? She gets COB ration w/Calf Manna for a total protein of about 17% at milking time. Almost free choice 2nd and 3rd cut alfalfa hay (nice hay) and of course free choice minerals and water. Thanks for the help.
