Diagnostic Test Breakeven Calculator
This spreadsheet can be used by veterinarians and diagnostic laboratories to
evaluate the economic return for implementing herd diagnostic screening for
diseases affecting beef cattle. It also evaluates the sensitivity of the assumptions used by the veterinarian.
Calculating Trace Mineral Supplements
This spreadsheet aids beef producers that utilize custom mineral mills in formulating appropriate
mineral mixes. It is not as comprehensive as the Mark Trump / Kenneth Suter Mineral Calculator nor
does it calculate least-cost alternatives.
Mark Trump / Kenneth Suter Mineral Calculator
Microsoft Excel-based mineral calculation program that determines
the cost of minerals fed to livestock
Evaluating Marketing Options for Cow-Calf Producers
This spreadsheet can be used by cow-calf producers to help determine whether to:
Determining Replacement Rate for Cow-Calf Herds
This spreadsheet can be used to determine the number of replacement
heifers needed to keep the herd size constant given the
pregnancy/retention rates for each age classification of cows.
Determining the Value of Replacement Heifer Development
Systems
This spreadsheet can be used by producers and their veterinarians to
determine the value of an alternate heifer development system
compared to the farm's current production inputs. You will be asked
to fill in several variables concerning the herd's current
production and economic situation. The output is the amount of
dollars available for the farm or per pregnant heifer to move to the
alternate system. By using several production scenarios (expected
case, best case, worst case), a confidence range can be produced for
your situation.
Evaluating Mineral Feed Tags for Beef Cows
This spreadsheet calculates the percentage of NRC requirement for
essential minerals that is supplied by your mineral source from
information available on the feed tag.
Pregnancy Histograms
This spreadsheet can be used to create pregnancy histograms. Inputing several variables
will allow the user to customize the spreadsheet to their own opperation.
Using BRD-Treatment Option Calculator
This spreadsheet can be used by veterinarians consulting with feedlot
and stocker cattle producers interested in evaluating their options
for treatment protocols for bovine respiratory disease. The
spreadsheet allows you to compare your current therapy (cost and
"death rate following treatment") with an alternate treatment of a
different cost. You will be asked to fill in several variables
concerning the situation you are evaluating. The output is the needed
"death rate following treatment" for the alternate therapy to be
economically equivalent to the current therapy. By using several
production scenarios (expected case, best case, worst case), a
confidence range can be produced for your situation.
Evaluation of Buying Feeders
This spreadsheet can be used by producers interested in feeding cattle
until slaughter. The spreadsheet can be used to estimate three
outcomes:
You
will be asked to fill in several variables concerning the feeding
situation you are evaluating. This set of calculations is designed to
aid in determining an outcome with a given expected performance
(health, growth, sale value). By using several production scenarios
(expected case, best case, worst case), a confidence range can be
produced for your situation.
Evaluation of Buying Stockers
This spreadsheet can be used by producers interested in growing
stocker cattle. The spreadsheet allows you to have a period of
confinement where the cattle are receiving a majority of their
nutrient needs in the form of harvested feedstuffs (silage, feed
grain, hay, etc.) followed by a period of time where the cattle are in
a grazing situation (with or without additional supplement). The
spreadsheet can be used to estimate three outcomes:
You will be asked to fill
in several variables concerning the stocker situation you are
evaluating. This set of calculations is designed to aid in determining
an outcome with a given expected performance (health, growth, sale
value). By using several production scenarios (expected case, best
case, worst case), a confidence range can be produced for your
situation.
Evaluation of Retained Ownership vs. Sell at Weaning
This spreadsheet can be used by producers interested in evaluating
their options for selling calves at weaning or owning them for a
period of time past weaning. The spreadsheet can be used to estimate
two outcomes:
You will be asked to fill in several
variables concerning the situation you are evaluating. This set of
calculations is designed to aid in determining an outcome with a given
expected performance (health, growth, sale value). By using several
production scenarios (expected case, best case, worst case), a
confidence range can be produced for your situation.
