Version history

Version 1.8.1.0 (released 07/02/2024)

• The InraPorc program is now available in Chinese

Version 1.8.0.0 (released 12/07/2023)

• Communication with server (TLS 1.2)

Version 1.7.1.0 (released 21/10/2016)

• The 2D-graph representing the response of protein and lipid deposition to energy intake includes two data points reflecting the actual protein deposition, lipid deposition, and energy intake. This representation and some of the associated traits may be difficult to interpret when a feed restriction is applied. Therefore, additional data points have been included that represent the situation for ad libitum feeding, making the 2D-graph consistent with the 3D-graph.

Version 1.7.0.0 (released 05/04/2016)

• The Web server has changed, HTTPS is now used
• Some fixes in the calculation and display
  • Crude fat of some ingredients
  • Percentage of feed for a transition with rule changes on duration
  • Improvements on graphics

Please note that previous versions do not support automatic redirection. It is therefore necessary to perform this update in order to use the automatic features like requesting a license activation key and checking for updates.

Version 1.6.5.8 (released 16/01/2014)

• Feed ingredients supplied (in the previous version, confusion on free amino acids and vitamin and mineral products)

Version 1.6.5.7 (released 23/08/2013)

• Several bug fixes
• Updated on 04/09/2013 (feed ingredients translation)

Version 1.6.5.3 (released 10/11/2011)

• Improved calibration of growing pig profile

Version 1.6.4.0 (released 23/05/2011)

• Post-absorptive efficiency of isoleucine utilization was changed from 60% to 67%. This means that the ideal Ile:Lys ratio will change from approximately 60% to 55%.

Version 1.6.3.8 (released 25/02/2011)

• Install a new dataset from the File menu
• Fixed small problems viewing the simulation results (units) related to the translation system
• Display a warning when an amino acid limits protein deposition when calibrating a growing pig profile

Version 1.6.3.3 (released 09/11/2010)

• New logo in reports
• Check the license data validity when "Automatic" or "Manual" button is clicked

Version 1.6.3.1 (released 08/11/2010)

• Resolve an issue displaying rules in feed rationing plans for growing pigs
• Don't ask for data conversion in evaluation and read only modes

Version 1.6.3.0 (released 22/10/2010)

• Upgrade to Delphi 2009 (Unicode)
• Automatic search for new versions
• License activation key requests simplified

Version 1.5.3.1 (released 10/06/2009)

• Correction of a few other bugs when exporting the composition of feeds and feed ingredients to Excel.

Version 1.5.3.0 (released 18/05/2009)

• Correction of a few bugs when exporting the composition of feeds and feed ingredients to Excel.

Version 1.5.2.2 (released 11/03/2009)

• Correction of a few calculation errors in the report of multiple simulations (comparison and sensitivity analysis).
• Correction of a few calculation errors in the export of simulation data to Excel.

Version 1.5.2.0 (released 18/02/2009)

• Because of the changes me made in this new version, we had to change the structure of the datafiles. This means that the new version will not be backward compatible with earlier versions of InraPorc. Although the conversion process should be safe, it may be good to make a backup of your datafiles before migrating to the new version.
• Many new features in the animal profile for growing pigs:
  • Estimation of model parameters from observed feed intake and growth data. You can now provide your observed data and InraPorc will calculate the parameters for the animal profile that will fit the data best.
  • A new function for describing the ad libitum feed intake. With the Gamma function, feed intake is described relative to the maintenance energy expenditure. With this function, it is possible to have a declining intake with increasing BW.
  • In addition to the ad libitum feed intake, you can also provide another feed rationing plan in the animal profile. This will allow you to see how the animal responds to a feed restriction, relative to the ad libitum feed intake.
  • Many interface changes.
• Feed wastage can now be defined in a feed rationing plan. Each rule within a feed rationing plan can have its own percentage of feed wastage.
• The equations for backfat thickness and lean meat percentage are changed. Lean meat percentage now corresponds to the European definition of lean meat. User-equations for backfat thickness and lean meat percentage can be defined in the configuration menu.
• Correction of several small bugs.

Version 1.4.0.2 (released 19/09/2008)

• The statistical algorithm for estimating parameters of the sow profile has been changed. This has greatly reduced the time to perform a calibration (from about 5 minutes to typically less than one minute).
• A bug concerning phosphorus retention is corrected. It is now also possible to distinguish fecal and urinary phosphorus excretion.

Version 1.3.2.5 (released 25/03/2008)

• Correction of a minor bug in the animal profile of sows related to the calculating the mean values of the herd.

Version 1.3.2.4 (released 07/03/2008)

• Correction of a minor bug related to the use of the French or English helpfile when switching between languages.

Version 1.3.2.3 (released 05/03/2008)

• If the default directory does not exist, InraPorc will no longer propose to correct the data files (*.rec).
• Correction of a bug related to the export of multiple raw materials and feeds to an Excel file.

Version 1.3.2.1 (released 15/11/2007)

• A minor bug was corrected that caused some buttons to be displayed in French (Oui, Non), rather than in the selected language.

Version 1.3.2.0 (released 12/11/2007)

• A bug was corrected that caused the reports to be displayed and printed in English, rather than in the selected language.

Version 1.3.1.0 (released 25/10/2007)

• In the INRA-AFZ database of feed ingredients, two aspects have been modified:
  • DL-methionine now has a sulphur content (it was zero)
  • the lactose of dairy products is now included in the sugar fraction (it was included in the residu fraction)
• A translation bug in the Dutch language has been corrected.

Version 1.3.0.0 (released 11/10/2007)

• InraPorc is now available in Polish.
• The system of working with new languages has completely been changed. Although this may not be visible to most users, it greatly facilitates the translation of InraPorc into other languages.
• A new warning message has been included to alert users that the nutrient requirements predicted by InraPorc are (too) low. Part of this is due to the fact the requirements are predicted for an individual animal and not for a population. See the publication list for more information on this topic.
• A bug was corrected that caused an error when the initial body weight of the pig was reduced to a low value.

Version 1.2.1.1 (released 15/05/2007)

• A bug was corrected that resulted in an error message (and system lock-up) during printing when working in a language other than French.

Version 1.2.1.0 (released 09/05/2007)

• The help system has been modernized.
• Many internal changes allowing the translation to other languages (Brazilian portuguese has now been included, Polish will follow later).
• The import/export module of feed ingredients and feeds has been modified. Data can now be imported and exported according to a user-defined configuration.
• For growing pigs, raw simulation data can now be exported to an Excel spreadsheet file (InraPorc.xls). This allows the user to build their own calculation modules in Excel (e.g., to perform an economic evaluation) using InraPorc to provide the technical data. The raw data are written to a specific InraPorc tab-sheet of an Excel file. The other tab-sheets can be used to construct additional modules. This option is available for a single simulation (i.e., 1 data line of raw data) and for comparisons of simulations (up to 5 data lines of raw data).

Version 1.1.0.2 (released 27/02/2007)

• Another minor bug fix for the feed rationing plan (growing pigs).

Version 1.1.0.1 (released 16/02/2007)

• There was a bug in the calculating the order of first-limiting nutrients (growing pigs).

Version 1.1.0.0 (released 13/02/2007)

• In the feed ingredients tab-sheet of a feed, a feed ingredient can be easily exchanged with another without changing the quantity (for example, exchanging corn-oil for soy-oil on an equal-quantity basis).
• The list of feed ingredients used in a feed can be sorted alphabetically or based on level of incoporation in the feed.
• The data integrity is now checked when loading a dataset. If errors are found in the links between the different datafiles, the broken links can be deleted, allowing you to regain access to the datafiles.
• Several additional bugs were corrected.

Version 1.0.5.0 (released 09/01/2007)

• The total consumption of feed ingredients can now be displayed in a simulation (e.g., the total quantity of wheat consumed during the production cycle).
• Mostly for educational purposes: the response of growing pigs to the energy supply can now be displayed as a 3D-graph. This option is accessible in the "animal profile", using the tab-sheet "Response to a feed restriction" and clicking on the "Response curve" button.
• A few minor bugs were corrected.

Version 1.0.4.1 (released 08/09/2006)

• The raw data of a single simulation can be exported by right-clicking on the graph. Data are saved as a CSV-file so that it can be used for further calculations or in presentations.
• A few translation errors of feed ingredients in US-English are corrected.

Version 1.0.4.0 (released 31/08/2006)

• The InraPorc program is now available in six languages: French, English (USA and UK), German, Dutch, Italian and Spanish. Helpfiles are available only in French and English.
• Information concerning the residue (organic matter minus protein, lipid, starch and sugars) is shown. The residue is used in the calculation of energy values.
• The "Enter" key can be used to move to the next field.
• A warning message will be shown if the information in a feed rationing plan, feed sequence plan or animal profil is incomplete. Prior to this change, an incomplete feed rationing plan could be saved but was not available for a simulation. This is still the case, but the user is now alerted that the feed rationing plan is incomplete when he saves it.

Version 1.0.3.2 (released 11/07/2006)

• Correction of a bug when comparing simulations.
• The Inra-AFZ database of feed ingredients is no longer required in the data directory. The list of feed ingredients is displayed in the same language as the program.

Version 1.0.3.1 (released 29/06/2006)

• Change of the QuickReport version.
• The printing error "Ressource TQRProgressForm non trouvée" when using InraPorc in languages other than French has been resolved.
• The printer can be changed in the print preview window.
• Reports can be exported as PDF files.
• The main window is no longer grey but includes an image.
• A personal logo can be inserted in the main window of InraPorc.
• The configuration settings are saved when quitting the configuration and not when quitting InraPorc.
• When changing the language, the message that InraPorc has to be restarted will be shown when quitting the configuration menu.
• When the default data directory is changed, it will be used immediately (and not after restarting InraPorc).
• A change in digestibility of organic matter for sows had no effet on energy values.
• The calculated mean interval between weaning and estrus was incorrect.
• In the feed rationing plan for growing pigs, a percentage of ad libitum feeding can be used. Also, a rule can now be changed once a certain level of feed intake has been attained. Feed intake can be entered on a dry matter basis.
• The increment values when for the growing pig profile have been changed.
• The layout of the comparison module for simulations for growing pigs has been changed.
• For growing pigs, results can also be displayed as feed efficiency (i.e., gain/feed). Feed efficiency and feed conversion ratio can now also be expressed on an energy basis.

Version 1.0.2.3 (released 16/05/2006)

• A change in initial BW resulted in a division by zero.
• The marginal PD and LD marginal values were incorrect when showing the graph of the response curve to energy.

Version 1.0.2.1 (released 12/05/2006)

• When the initial or final conditions of a single simulation were changed, the calculations were incorrect.

Version 1.0.1.3 (released 11/05/2006)

• Initial release
