In the dairy sector calves should be weighed at the start of the housing season to give an indication of how far off they are from the target weight they need to be at for breeding. They should be weighed again at turnout again to determine are they near breeding weight or to determine if they need to be fed more meal at grass to reach optimum breeding rate. Finally they should be weighed at second housing to determine if they will be at optimum weight at calving down.
In the suckler herd calves should be weighed 2/3 times in their first year to determine performance.
Similarly to dairy stock they should be weighed at the start of housing and end of housing. Weighing prior to slaughter will give an indication of kill out ratio.
