Mastitis and dry cow treatment
Mastitis management and control has been a long
sought after goal in the dairy industry. Unfortunately it
has also been an elusive goal. With all of the work and
studies and 'research being done on the problems of
mastitis, the incidence of mastitis has not decreased
markedly over the past SOyears. Approximately 50 per
cent of the cows in car dairy herds are still infected.
In many herds the extent of mastitis control is simply
the infusion of a- prepared treatment 'into- a quarter
whenever there is a flareup. ‘ But the most rewarding
results in mastitis control and management can be ob
tained from a properly conducted ,dry cow program.
Today, treat or not to dry treat; that has been the much
argued question ever since dry treatment was first in
troduced. There is little argument that at least problem
cows should be dry treated. But highly qualified and
knowledgeable people will still argue both sides as to
whether all cows should- be dry treated. Let’s examine
both sides.
Why dry treat only problem cows? In tills cast problem
cows can be divided into two categories. One way is to
treat only those cows which have had actual cases of
mastitis during the lactation. The second method goes one

step further, and, as many farmers do, have the cows
cultured when they are due to go dry and treat only those
animals which show infection at that time. .Why not treat
all the cows? The expense of the product is one reason but
is not a valid, argument considering the consequences.
“Why bother to treat an animal which does not have a
problem? is another comeback. More serious and not yet
resolved problems is the possibility that continued and
' constant use of a dry treatment product in- every cow will
result in development of resistant strains of bacteria
which will then not respond to regular treatment. This is
always a possibility but has never proven td be of suf
ficient significance to be of concern. ■ " ■ -
. Another more serious drawback had been the evidence
that dry cow treatment which eliminated' the more
common, routine,- easily - treated organisms from the
udder, made it more susceptible to the more serious acute
coliform mastitis. In some herds it did appear that as 100
per cent dry treatment was'practiced and routine cases of
mastitis subsided, that there was an increase in acute,
coliform mastitis. However, this increase appears to be
related to environment and management also. It is
possible that the staph and strep free udder is more

manure contaminated areas. So a complete dry cow
treatment program will have to be coupled with improved
environment management to prevent contact of the udder

It’s a great feeling to know that you are the master of
your farmlands , that when you treat your soil right,
it will treat you right. Liming is one of the most impor
tant factors in keeping your soil in the highest produc
tive range. -By raising the pH from a level below 6.0 to
6.5 or higher, you can expect to harvest .8 more tons
of alfalf? per acre; with similar increases for all other
forage and cash crops.
