I have these little holstein bull calves and there is something wrong with em. They just get the runs and this one here was fine and acted ok last night and ate its full bottle then this morning it's laying flat doesn't wanna eat and just acts like it wants to die. Wednesday that happened to a little heifer she's about a week and a half old and she ate the night before had the runs but wasn't dehydrated and then I went out and she was dead. I'm giving penicillin, probios and putting an egg in their bottle, and also SMZ tablets. What's the deal? This one today got Baytril, Banamine, blue scour tablets, and 3 pints of an eletrolyts solution plus nutridrench. Any ideas? This is a big deal this is the 3rd one out of 7 that is acting like that. They are being fed raw cows milk a bottle twice a day.
