are from heifers that may not have calved themselves yet and as such, we will not have had the opportunity to see the phenotypes of the

in total ? we can see that these
bull
dams
have produced almost 11,000 kg milk with 4.27% fat and 3.62% protein. please note that 80% of these
dams
are 1st calf cows so this is a very high production level. in comparison, in table 2 we can see the average classification of the
bull

with 83 for frame, 84 for feet and legs and 85 for mammary. as mentioned, it takes quite something to be among the selected
