Ok, long story here...Usually raise 300 lb Holstein steers, but the sale barn didnt have any so I brought home some 185 lb steer calves. They took to the water, calf starter (and medicated crumbles), and hay fine.I have had them 1 week. They must have just been weaned because they will still suck on just about anything. 1 calf was hanging back and clearly not eathing much, but when I would go into the pen with a bucket of feed he would bolt away. I figured if I couldnt catch him he must not be too bad. I went to feed them this morning before work and this one didnt want to get up. I got in the pen and gave him a shot of LA-200, and got him up. He didnt want to move around at all, and wouldnt eat. He was holding his head low, and didnt look well at all. Came home at noon and he was out side the barn with all the others. This evening he was down again, and not eating. I decide to drench him some electrolites. When I put the tube in he latches on and sucks on to the tube and has the 1500 ml down in no time. I decided that maybe he wasnt weaned like the others and needs some milk. I got a new bottle and some replacer. He latched right onto the nipple and sucked like crazy, but after a minute or so almost nothing was out of the bottle. It looks like the nipple has an air vent in the top that should wasnt punched open. I punched it open, and he went to town again, but still the milk is barely coming out. How long should it take for a calf to finish a 2L bottle? I finally poured the milk into the drencher, and with some care he drank 1/2 the bottle. It seamed like the nipple wouldnt let the milk out fast enough. Should I just keep trying to bottle feed him till he gets his strength and drive back? He was born 8/2. How much milk should I feed a calf that age? Thanks for any info. I usually dont deal with the bottle babys so this is a little new to me.
