An Excel Spreadsheet is available to help dairy
producers and their consultants to evaluate the economic
feasibility of anaerobic manure digesters that use
flushing systems for manure management. The
spreadsheet considers both sales of gas and/or sales or
reduced purchases of electricity and is based on standard
investment analysis techniques. The documentation is

DairyVIP is an Excel-based computer program that
assists dairy farm consultants and dairy producers to
evaluate the consequences of changes in herd
management and prices on dairy
farms. The user-friendly program
uses farm-specific inputs related to
prices, milk production,
reproduction, involuntary culling,
body weights, breeding and culling
decisions, and other important
inputs. Seasonal effects can be soueeta MHk, I..
included. DairyVIP first determines Dairy Check4ff
the herd demographics that follow from these inputs.
The herd demographics then determine over 40 herd
statistics such as profit/slot/year, cull rates, calving
interval, and many more. Results can also be displayed
per cwt milk yield. Two sheets with over 70 figures
based on the results are also shown. The consequences
of two different sets of inputs can be compared side by
side. The latest version of DairyVIP, including
documentation, can be downloaded from the Florida
Dairy Extension website at http://dairy.ifas.ufl.edu/tools.

Since it's time to cool cows again, it's time to tune
up your cow cooling systems. The first thing is to clean
your fans; dirty fans reduce air speed by 50%. With the
price of energy these days it is important to keep the fans
clean. It is not against the law to clean fans twice a year,
especially if you have dusty roads near the barns. The
faster the air movement around the cow, the faster the
sprinkler water will evaporate from the cow's skin and
the cooler they will be. The cooler the cow is the more
food she will eat and the more milk she will produce.
Fans will use the same amount of electricity if they are
dirty or clean, so keep fans clean.
The second part of the cow cooling process is the
use of water to be evaporated off the cow body to take
the heat with it and cool the cow. This means that you
only need enough water to get the cow wet to the skin,
then turn the water off and the fans will evaporate the
water from the cow. Adding too much water reduces the
efficiency of this process. The excess water runs off the
cow to the floor to the lagoon.

To conserve water you should adjust your sprinklers
to just add enough water to soak the cow's skin and start
to run off the cow. The length of the off cycle should be
long enough to let the fans evaporate the water off the
cow and then start again. There are some very good
sprinkling controls on the market that are easy to adjust
and will add more cycles as heat increases.
One of last year's Dairy Check Off Projects was to
determine the results of turning sprinklers off on one
side of a barn at the Dairy Research Unit at midnight and
turn them on again (by timer) for one hour after the cows
came back from the milking parlor.
Our night time cycle for this
particular barn is one minute of
water every ten minutes. This is a
very short cycle compared to most
dairies. The water saving was 600
gallons of water per cow from the
end of May to the first week in
s.bary s1k, Ic. October. On a 1000 cow dairy this
ar will be 600,000 gallons of water
saved, 1.2 million gallons on a 2000 cow dairy.
Remember that the less water you use, the drier the
floors and the lower the humidity in the barn.
Sprinklers are stationary, cows are mobile. All it
takes is a timer in front of the sprinkler controller to shut
off the water when cows are in the parlor, laying down
etc. If you don't have timers on the sprinklers, you are
wasting water, and have soggy cows and are filling your
lagoon. Less Is More!

PCDART is used by 113 herds in Florida and
Georgia. A new program release, version 7.9, is
expected any day now. This release will include the
Protocols and Ci, system which has been under
development for the last 30 months. The new system
allows each herd to define an unlimited number of
chores, each of which can be a drug, vaccine, treatment
or therapeutic action. This major enhancement will
allow users a new way of listing cows for action based
on pre-designed set of chores called a protocol. A
dynamite feature is the ability to designate milk and/or
meat withholding time for each chore. The use of these
allows automatic listing of cows for which milk or meat
should be withheld from market or conversely, when
cows can be moved out of the hospital herd. Herd
managers can summarize chores by date, count or
percentage. This is truly a major enhancement that
offers comprehensive herd health management options.

For herds where protocols don't fit the management
plan, the use of chores alone can offer a way to simplify
and improve the recording of health events and
treatments. Also, significant use of chores can be
applied to heifers.
To get a first-hand view and details on the new
version, plan now to attend the PCDART workshop
in Gainesville on May 2 as a part of the 2007 Florida
Dairy Production Conference. The workshop starts at 9
a.m. and the location is the Hilton University of Florida
Conference Center, located at 1714 SW 34th Street,
Gainesville, Florida.

Summary results of the 2005 financial and
production Dairy Business Analysis Project (DBAP)
survey are now available at the Florida Dairy Extension
site at http://dairy.ifas.ufl.edu/dbap (look for "Dairy
Business Analysis Project: 2005 Financial Summary").
Both an html and a PDF version of the report can be
viewed and downloaded for free.
Twenty-one dairy producers in Florida and Georgia
participated with their completed 2005 data. The
summary consists of 16 tables and 5 figures detailing the
collected information. Data is grouped by business size,
production efficiency, revenues and expenses, financial
performance indicators, and balance sheet information.
Sorts are by state, herd size, milk per cow, net farm
income per cwt, rate of return on assets, assets per cow,
and liabilities per cow.
Interested dairy producers can still enroll to
participate with their 2006 data. In return, participants
will receive a report that benchmarks their financial and
production performance with other participants in the
project. Anonymity of data and participants is
New this year is that we will provide a benchmark
report early in the year for those producers who submit
their data timely. A second, final benchmark report will
be provided when all data has been collected this year.
