Maximizing Genetic Progress
The amount of progress that can be gained from an A.I. program can be divided into four specific areas as shown in Table III.
Most progress is made in selecting sires to produce the next generation of bulls, with 43 percent of the total genetic progress in this area.
The second most influential factor in genetic progress comes from selecting dams of future bulls (33 percent).
Selecting a group of sires to breed your cows accounts for 18 percent of the total genetic progress, whereas the selection of dams to produce cows is the least important, accounting for only 6 percent of the total.
