Most calves are weaned by this time, thus may be still called calves, but others may call them heifers (if female), bulls (if intact) or steers (if castrated).
If it's weaned it's called a weaned or weaner calf. If not, it's still a calf.
That all depends on what breed that beef calf is. A 1 month old beef calf can weigh anywhere from 80 lbs to over 200 lbs or more.
A 6 month baby is six month old
I think it depends on what you're saying. eg. A six-month-old rabbit or. A rabbit that's six months' old.
This all depends on the breed. Three-month-old calves of different breeding will weigh more or less than the other. For instance, a Charolais calf will weigh more than a Jersey calf, or a miniature Angus calf will weigh less than an Angus calf (one that is normal in size and proportion).

A calf can be sold when he is only a day or two old. But this is highly unrecommended, because of the high stress these baby calves go through, which can lead to sickness, injury and even death. A calf that has been weaned off the bottle at 3 months of age has a better chance of surviving his ordeal at the stockyards than a two day-old calf. Six month old calves that have been weaned off their mothers have an even better chance than 3-month old or two-day old calves do. So it all depends on when you want to sell, if you have the heart to let them go.
Around 300 lbs.
That depends on the breed. Since this is in the Jersey cattle category, the weight of a three-month old Jersey calf would be around 150 to 200 lbs at the most.
Depends on the breed and body condition of the calf. A 600 lb Jersey calf can be around 7 to 8 months old, whereas a 600 lb miniature calf may not be a calf at all, but a 15 month old heifer or bull. A soggy Angus calf at 600 lbs may be at around 5 to 6 months of age.
The most accurate way to tell the age of your calf is by looking at his front teeth. A newborn calf will have no teeth; a week old calf will only have maybe one or two teeth that have popped up already; a 1 month old calf will have all 8 lower incisors already.
Usually around 200 lbs.
