Calf was born backwards, She never got past the feet before I noticed and pulled it.  Very big bull, and very stupid.  After 6 days, he still won't suck a bottle, finger or the cow.  A few times he has taken the initiative to go poking around the bag, wagging his tail and bunting, but stick a tit in his mouth, or squirt some milk in and he gets quite upset with the interference.  We've had the odd calf do this, but they always figure it out by the third day.  The old cow has a big bag and big tits, but is very cooperative and patient with my efforts.  

Are there any tricks to train this calf to suck?  Me and the cow are both running out of patience for this routine, she doesn't want to be a milk cow, and being a milk maid wasn't one of my ambitions in life, so I would like to eliminate the middle man.

He has had vitamins, A D E, Selenium, B and Cortizone with antibiotics, temperature is on the high end of normal, acts healthy and normal.
