12—Lancaster Farming, Saturday, October 9,1971
A Registered Holstein Cow owned by Paul B. Zimmerman,
Ephrata RDI, completed the highest 305 day lactation. Agnes
produced 21,008 pounds of milk, 866 pounds of butterfat with a
41 per cent test. Second high lactation was completed by a Regis
tered Holstein Cow owned by Mervin Nissley, Bainbridge RDI
7 produced 20,957 pounds of milk, 859 pounds of butterfat with a
41 per cent test in 298 days.
The herd of Christian K. Lapp, Gap RD2, had the highest
daily butterfat average. This herd of 39 0 Registered Holstein
Cows averaged 52 4 pounds of milk, 183 pounds of butterfat with
a 35 per cent test The herd of Paul B. Zimmerman, Ephrata
RDI, placed second. This herd of 33 0 Registered Holstein Cows
averaged 49 4 pounds of milk, 1.82 pounds of butterfat with a 3.7
per cent test

Several items such as breed,
age, production level, season and
genetic make-up are linked to
twinning, but the most important
cause of twinning, from a
management standpoint, is
681 hormone unbalance.

Twinning In Dairy Cattle
Even though twin calves are
interesting, especially to farm
visitors, dairymen who prefer to
have calves born singly rather
than as multiple births have good
reason for their preference.
Studies have shown that there are
disadvantages associated with
twinning.
About 90 per cent of the heifers
born twin to bulls are non
breeders.
Also, twin calves are more
difficult to raise and have a
higher mortality rate than single
birth calves.
The effects on the cow are
perhaps even more important.
Cows having twins are more
likely to have retained placentas;
are more difficult to breed back
and have longer calving in
tervals. They often produce less
milk during the succeeding
lactation
For example, cows with cystic
ovaries are about 10 times more
apt to have twins than non-cystic
cows. Home studies have shown
that more than one-third of the
cystic cows had twins.
This might be the result of the
cystic condition itself or it may be
related to the effects of treating
this condition with hormone
injection.
Serious hormone unbalances
often result from the treatment of
such conditions as retained
placenta or absence of heat signs
with hormone injections. Such
treatments may be indicated in
some situations, but their in
discriminate use should be
discouraged. They should be used
only under the supervision of a
veterinarian.
Large Cows vs. Production
Dairy cows that are above
average in weight for the herd
tend to be less efficient than
small ones in converting feed into
milk, according to a recent USDA
study. The study indicates that
body size alone is not sufficient
basis for selecting cows, but it is
a factor to consider in evaluating
animals for profitability.
The USDA found that two-year
old cows studied hit both their
peak feed efficiency and their
peak income-over-feed cost at
about 1,170 pounds, even though
herd average weight was 1,280
pounds. The 1,170 pound cows
earned $320 over feed cost, but
cows weighing over 1,450 pounds
in first lactation earned only
about $250 over feed costs.
Since smaller cows had higher
income-over-feed cost, delaying
the breeding of heifers to attain
large body size is not necessary,
the study concludes.
