If he's not even attempting to nurse and you had to pull him I'm assuming he's dystocia and most likely has a swollen head/tongue? Does he even attempt to suck on your finger if you stick it in his mouth? I give calves like that a shot of Vitamin B Complex for energy, Banamine to help reduce swelling and Nursemate ASAP. You'll probably have to continue to tube him while you train him to nurse &/or take a bottle. Next time mama's in the chute, secure him with your legs, hold his head, guide it to the teat and literally open his mouth with your fingers & put her teat inside. Hold his head/clamp down on his mouth (not hard) so he doesn't pull away and squeeze the teat so he gets a taste of her milk. If this doesn't get him interested, stimulate his mouth/sucking reflex by moving her teat in-n-out, just a little. Good luck!
