Once these goals are objectively
evaluated, a sound genetic program can emerge.
If the A.I.organization you are using has a sound genetic program, 76
percent of the genetic progress you can make is being taken care
of for you.
You then only need to worry about the remaining
24 percent, 18 percent of which is accomplished by choosing a
group of sires available from the A.I. organization that fits your
selection goals.
The remaining 6 percent involves the selection
of cows to produce replacements. The genetic progress from
the selection of cows to produce replacement is low because
a producer has a limited number of cows to use to produce
heifers, thus greatly limiting genetic progress.
