Profitable Breeding
One of the secrets of a success
ful and profitable dairy breeding
program is the consistent use of
top genetic bulls on all cows from
which you intend to keep any
offspring, according to VPI dairy
specialist, Bennett CasseL Each
breeding on your farm, including
services to heifers and problem
breeders, is an opportunity for
making genetic progress in your
On many farms, one third or so
of the offspring that are bom and
raised for herd replacements come
from first calf heifers and problem
breeders. These heifers and prob
lem breeders should be bred, not
to non-dairy bulls or bulls of
unknown genetic origin, but to
bulls that have the opportunity to
introduce some good genetics into
the herd at reasonable costs. If you
are interested in using A.I. sires on
heifers, but find it difficult to
detect heifers in heat or inconve
nient to constrain them for servic
ing, consult your veterinarian and

This is not to say that all the
good bulls are in A.I. service.
However, A.I. bulls generally do
have a lot more records making up
their proofs, which means you can
more reliably predict the impact
they may have on your herd. Herd
sires will continue to be used for a
variety of good reasons, some of
which are: convenience, improved
conception in some cases, person
al preferences, developing proofs
to merchandise bulls, etc. The
noint is, if you are going to use
natural service, select healthy, vir
gin dairy bulls out of good genetic
stock and switch bulls frequently
enough to reduce the risk of a
“dud” bull leaving a big hole in
your breeding program.
What are “top genetic” sires?
That varies, depending upon who
you talk to, and upon individual
Breeders’ goals. For one breeder it
might be sires with high PD values

If you have been selecting ser
vice sires wisely and making
genetic progress with each suc
ceeding crop of calves, the best
females in your herd should be in
your young heifers not yet bred.
You probably would not think of
breeding your best cow in your
milking herd to any old bull of
unknown genetic origin; nor
should you do this with your best
females in the herd, your youfig
The trouble is, you don’t know
which heifer will be your best cow
of tomorrow until she freshens
and proves herself. However, your
DHIA reports can give you a clue
if you have been reporting breed
ing information and animal identi
fications accurately. It will show
up on your reports as parent aver
age (PA) or estimated transmitting
ability (ETA). These estimates
consider what the calf has inher
ited from its dam and sire.
On the Penna. DHIA reports
parent averages (PA) of calves can
be found on their dam's Individual
Cow Page.
Several Raleigh DHIA reports
show calves estimated transmit
ting abilities (ETA). It may appear
ETAP, etc. You can find it on one
of the Individual Cow Records
(DHI-303. but not on DHI-203),
and on die following optional
reports, if requested: Annual Heif

Calf Management Listing
(DHI-214), and calves Individual
Identification Page (DHI-204).
So. for good genetic progress,
and to keep your breeding prog
ram on a well-planned track, plan
what sires you want to use consid
ering: breeding goals that will
have a positive financial impact
on your business, bull’s genetic
merit and reliability ratings,
semen costs, etc. Here’s where
you might want to solicit the
experience of a breeding
Then, determine how much
semen you will need for the next
six months or so. With this infor
mation in hand you are now in a
position to shop for the semen and
breeding services you need in a
very methodic, business-like man
ner. This will help you avoid the
temptation of buying a few straws
of a new “hot" sire or from over
stocking your semen tank.
When die next sire summary is
published, be ready to revise your
list of chosen sires and prepare
your shopping list for the next six
months or so. Remember, proofs
of young sires you chose earlier
may change when their second
crop of daughters come into milk.
With the rapid genetic progress
that is taking place in the industry,

How well have you been doing
keeping your herd genetically
ahead of the average, and toward
the front of the pack? The genetic
profile of the sires you have been
using is a good indicator. You can
And this on the Raleigh DHIA

may be to strive for an average

80% or above..
You may have many opportuni

cally. So do your competitors, so
don’t miss the opportunity to stay
abreast of or ahead of your com

is being able to manage the herd in
a manner that allows cows to
express their genetic potential and
remain in the herd long enough to
reward you with some good
offspring and profit margins.
