It is a new year once again. It is time to repeat what
we did right last year and not to repeat what did not
work well last year. Hurricanes caused more problems
than anyone could imagine.
Resolution #1 Cull chronic mastitis and other cows
that live in the hospital herd. To do this you must keep
records to determine which cows are the problem cows.
Many people keep records in a day book but never look
at it. PCDART has a herd health section to record all
health data. This data should be recorded and looked at
and culling decisions should be made on animals staying
longer in the hospital herd than the time needed to sell
milk to make a profit. If this time is longer than their
profit margin, cull them (30 days out of the bulk tank is
about the limit before they become unprofitable). You
can use hand recorded data as well to determine length
in the hospital herd. This is more important than ever
with the new "downer cow" rule. If you have a cow that
needs to be culled because she is lame or has chronic
mastitis or other problems, do not put her in a lot to lose
500 pounds and become a downer cow. Make the
decision before you fill her up with antibiotics.
Resolution #2 Milk clean dry udders, post-dip, and
keep equipment in good repair.
Resolution #3 Keep your cows cool. Our summer
research has shown that our cows became hot at night if
no sprinklers were used at night. When hot weather
comes, leave the sprinklers and fans on all night. Set the
sprinkler thermostat at 68 degrees F and run them all
night as long if the barn temperature is above 68F. Run
fans 24 hours a day if your cows have access to the barns
for that time.
Resolution #4 Clean your fans. For many
dairymen, the first time their cooling fans were ever
cleaned was last year when Charley, Jean or one of the
other hurricanes either blew in enough water to clean
them or they blew them into a new lake. Put timers on
your sprinklers (set the timer so the cow gets wet to the
skin, shuts off, and turns on again before the cow dries
off). Cooling occurs when we wet the cow and the fans
dry the water off the cow and take the heat with it.
Usually, sprinklers that are on for 1 to 2 minutes every
10 to 15 minutes will suffice, but this varies due to water

pressure fluctuations, supply, and pipe size. Set your
sprinklers individually for each barn, not what Joe Blow
down the road uses. Also keep in mind that dirty fans
are half as effective as clean ones.
Resolution #5 Keep your cows as clean and
comfortable as possible. Most of our mastitis problems
are due to Strep uberis. This organism lives in the
ground and in our free stalls, including sand bedding.
Bedded packs are a huge reservoir for mastitis pathogens
when wet and dirty. Remove old dirt in pasture mud
holes, put in clean dirt, especially in calving lots. Clean
and drain cooling ponds, keep free stalls and packs
bedded and clean.
Resolution # 6 Have a plan for the next hurricane.
Generator maintenance is probably higher on your list
than this time last year.
Resolution # 7 Enjoy life. You folks are among
the best people in the world. You have gone through
terrible hardships. This is a tough business in good
times, you did not need a bunch of hurricanes to
challenge you, but maybe some good may come out of
them anyway.
If you need help in any of these areas let me or any
of the Dairy Agents know. We will be glad to help.

With the departure of Dr. Mary Beth Hall, dairy
nutritionist, I have been asked about the timing of a
replacement to provide the dairy extension nutrition
support to the Florida dairy industry that has been
customary during Dr. Hall's tenure in the department.
The answer to that question requires an explanation of
the Institute of Food and Agricultural Sciences' (IFAS)
and the Department of Animal Sciences' processes for
filling faculty positions.
The IFAS administration releases positions to
departments for the purpose of recruiting new faculty

members based on the budgetary situation at the time
and the programmatic priority of positions within IFAS.
Then, within the Department of Animal Sciences,
faculty positions that need filling are prioritized based on
programmatic needs. This past year (FY 2004-2005)
IFAS has not released any faculty positions to be filled
due to budgetary constraints. Therefore, no attempt has
been made to fill any positions. The department has
prioritized positions to be filled and continuously revisits
the priorities as faculty members leave and new ones are
The Department of Animal Sciences has
programmatic responsibilities in four broad areas. These
are dairy, equine, beef and muscle foods. During the
time period beginning in 2000 and continuing through
2004, the department lost 20 faculty members from the
various program areas. Three of these 20 were faculty
members associated with the Poultry Science Program
which was terminated in 2002. During that same time
period seven new faculty members were employed with
an additional two employed to replace two faculty
members that left prior to 2000. The effective net loss in
faculty members from all programmatic areas within the
Department of Animal Sciences has been 10 since the
beginning of 2000. Naturally, with this magnitude of
faculty loss, each programmatic area, including dairy,
has very high priority faculty positions that need filling.
The reality is that, at least for the last 7-8 years, IFAS
has not been able to release enough faculty positions to
be filled to meet the department's high priority position
Obviously filling the dairy nutrition position is a
very high priority for the department. The dairy faculty
members in the department recently met and identified
the nutrition position and a lactation biology position as
two of the highest priority dairy program positions to be
filled. Very high priority positions for the department
have also been identified in the equine program. In view
of the present faculty staffing, the highest priority
position to fill is in the department's equine program
with the second priority position in the dairy program.
Currently we have two ruminant nutritionists in the
department with extensive dairy nutrition experience.
They are Dr. Charles Staples and Dr. 'Gbola Adesogan.
Although neither has any significant extension
appointment, they will try to address your most pressing
needs. Presently, I have no indication if any faculty
positions will be released by IFAS to the Department of
Animal Sciences for filling during FY 2005-2006. Be
assured that I and the entire Department of Animal
Sciences are committed to having strong dairy teaching,
research and extension education programs in support of
Florida's dairy industry and will be doing everything we
can in the present environment to provide the faculty
members necessary for that support.

The Department of Animal Sciences is pleased to
welcome Dr. Alan D. Ealy to the faculty. Dr. Ealy was
raised on a family owned and operated dairy farm in
Western Pennsylvania and received a BS in Dairy
Production from Penn State University in 1987. He then
attended Michigan State University and received an MS
degree studying the effects of negative energy balance
on reproduction in cattle. His PhD was completed at the
University of Florida under the guidance of Dr. Peter
Hansen where he investigated the effects of heat stress
on embryo development in cattle. Dr. Ealy held a
Postdoctoral Fellowship and later a Research Assistant
Professor position at the University of Missouri before
accepting a position as an Assistant Professor at Penn
State University in 2000. Dr. Ealy's primary research
interest at the University of Florida is to better
understand the events of early pregnancy in cattle so that
schemes can be developed to reduce embryo mortality in
dairy cattle. Dr. Ealy started his position at Florida in
the summer of 2004.
