Once they are weaned, they should not suck again. However the odd one seems to get into the habit again. This was one of the best heifers we had and we caught her sucking the cow. Problem is, the calf that was on the cow suffered. If we tried to wean her again, say put her with the bulls all winter, then back with the cows to calve, she will more than likely suck out on any cow we have that is close to calving. When this happens, the calf that is born will get no colostrum. Not good for the newborn. Also not good for the momma who has to raise a baby and feed another cow. In a sense it will affect your bottom line. Here is how
1. Cow that sucks will steal from any cow causing poor calves at weaning
2. Cows that get sucked on by another cow bring the momma down in condition, lowering her ability to feed her calf, maintain her weight, and re breed. So she will either not be bred the next year or be bred late, costing you in a smaller calf or no calf.
We have a rule, if a cow starts this bad habit, it grows wheels
On another note we BBQ some ribeyes from her....tasty Must have just been the way i cooked the roast
