I am a vet tech, depending where you are in the country will often dictate the mature size, Frame and weight of the particular breeds. There is greater diversity within breeds than accross them. Mature Cow weights for Southern regions range from 1000-1600, Mature Bull weights can range from 1400-2800. Factores such a method of development will also affect mature size, such as creep feeding or grass/ high roughage development, and Nutrition management through the first 3 years, cattle start getting mature teeth around 16-18 mo. of age, as this happens they may drop weith or fail to gain unless properly managed, this process continues into the 3rd year, Brahman breeds can take even longer.
Hope this helps
