Calves are born with teeth, but only a few have already emerged when they were born. By 1 month of age a calf should already have an entire set of 8 temporary incisors. Their adult teeth replace their baby teeth when they reach ~2 years of age.
Calves are born with teeth.
they dont. They only have bottom teeth for grazing.
They should, because at that age they're already start to eat more "harder" foods.
The calves are actually sexually mature and no longer "calves" by the time they lose their baby teeth, which is in fact around 2 years of age. You don't find this in feedlot steers because they have been killed and butchered (at around 14 to less than 24 months old) before they've dropped their baby teeth to be replaced by new ones. You find this more often in breeding bulls that are around 2 years of age, and heifers that have just had their first calf.
Highland calves can and should be weaned between the ages of 6 to 10 months of age.
Any age.
They do have teeth, they are born with two or three (a few none at all) and start growing their baby teeth until they are 2 years old.
Yes, most newborn calves have a few teeth already sprouted by the time they are born.
They can get grubs at that age if there is no deworming or anti-parasital program on your farm. If you deworm at the appropriate times, especially the cows, then calves at this age will not get grubs. But if you are concerned about bottle calves, then you should see your large animal veterinarian for a dewoming program for these bottle calves of yours. I would also recommend seeing what program is best for lactating cows with calves.
Yes, pretty much. The molars themselves are not exactly baby teeth as they don't fall out unless there's some sort of infection in the molars, but the incisors are baby teeth and will fall out when the animal reaches around two (sometimes three) years of age.
Depends on its sex and age. Older calves weigh more than younger or newborn calves; male calves weigh more than female calves.
Most calves are weaned at around 6 to 10 months of age.
