The University of California has developed several software items for
commercial egg producers. These can be run on IBM XT compatible personal
computers. This software has been tested extensively for up to 15 years in
hundreds of applications. Sample print-outs are available upon request and
sample runs using your own data are possible.
Stand Alone Software
The following two software programs are written in Microsoft Basic and
are available on one disk for $100.
- Replacement Program Analysis - This program analyzes various
molting and selling options to obtain maximum returns per 1,000 pullets
housed for comparable time periods (1 year). Some 300+ combinations of
1, 2 & 3 cycles of production are compared. All performance data and
prices are configurable to your standards.
- Single Flock Projection - This program is a projection of a
"real" flock for weekly performance throughout its life. Flock size,
housing date, performance standards and prices are user configurable.
Performance and prices can be varied monthly (e.g. feed consumption can
be projected to increase in winter; egg size to go down in the summer).
The following programs require Excel software. The programs
may be downloaded from this page by clicking on the highlighted file name
below. For some programs supplemental information is available; if
you want this download the reference material below the program.
- Daily Flock Record (DAYRECD-1)
- University of California Daily Flock Manager (revised July 2006).
This spreadsheet is designed for Microsoft Excel software users. (a
similar version is available for Lotus 1-2-3). The basic sheet provides
for five flocks and can be easily expanded for more. A companion
program, Weekly Flock Record (below), can be used in conjunction with this
program for other performance measurements (egg size, feed conversion,
In recent years, daily monitoring of egg production and
mortality has become more important as we try to determine when egg
production and/or mortality problems are just beginning relative to
disease and/or management. In order to effectively use this type of
data, it is imperative that eggs and mortality data are collected at the
same time for each day.
spreadsheet is designed to allow daily entry of eggs produced and
mortality counts. It is suggested that the reports be printed
immediately after the final egg collection for the day and made
available to management. Any measurable differences in egg production
rates and/or mortality need to be highlighted and acted upon as soon as
A record system for 5 flocks (can be expanded) to summarize daily hen
counts, mortality, and egg numbers into a weekly summary. This program
is intended to be used to provide flock managers with daily summaries of
egg production and mortality comparisons on a timely basis (the same
- Weekly Flock Record (WEEKRCD) - A record system for weekly
analyses of up to 5 flocks (can be expanded) comparing egg production,
feed consumption and conversion, mortality, case weights, egg mass and
- Molt Monitoring (MOLTSCHE) - This program monitors daily egg
production, mortality, and body weight losses during a molt. Also
included are molting method recommendations and a weekly summary of egg
production compared to a standard.
- Flock Indexing (FLKINDEX) - This program analyzes the economic
significance of multiple performance traits. Upon entry of beginning hen
counts, weekly hen day egg production, weekly mortality rates, weekly
average case weights and weekly feed consumption the program calculates
hen housed egg production, standardized egg values and feed costs and
weekly current and to-date flock indices (egg income minus feed costs
per hen housed).
- Depreciation and Interest Calculator (DEPINT) - This program
calculates annual and per dozen costs (interest and depreciation) of
pullets, and building & equipment costs (for pullets, layers and egg
processing) based upon variable inputs of interest rates and
amortization lives for buildings and equipment.
- Projected Energy Intake of Laying Hens (ENERGY)
- This program estimates dietary energy intake, feed consumption and
feed costs per dozen based upon temperature, body weight, egg mass (egg
production x egg weight), feed price, and feathering. Modifying any of
these factors will change the prediction.
information for energy program.
- Case Weights and Egg Values (CASEWT) - This program uses current
egg prices (user input) and standardized egg size distributions for case
weights ranging from 36 to 55 pounds (at 1/2 pound increments) to
calculate per dozen values (blend prices) for 39 different case weights.
In addition, it calculates second cycle case weight values with four
different egg quality scenarios.
- Summary of the Egg Check and Invoice (EGGRECAP) - A program that
summarizes the egg grade-out percentages, price relationships,
undergrade distribution and deductions. The system can be used for daily
or weekly analyses and for a single flock or multiple flocks.
- Cash flow for Replacement Pullets (PULLCOST)
- This program can be used for budgeting a future flock of replacement
pullets from 0 - 20 weeks or to keep track of actual costs. Itemized
costs with sub totals can be modified to meet company
information for replacement pullet program.
- Optimum Cage Density (OPCGDEN) - This program was written by Dr.
William Roush and modified by Don Bell. It compares net returns per cage
for different bird numbers per cage using variable egg production and
feed consumption data provided by the user.
