Dry matter efficiency

This report reflects the level milk yield produced per unit of dry matter consumed per day.  Producers may also see the DME(FPCM) which includes the fat and protein percentages (these percentages must be manually entered into the program).  You can select certain pens or all of them at once.

It’s showing:
  • what the dry delivered weight, dry recorded refusal and dry external concentrate for the pens selected were
  • the number of animals in the pens that day
  • dry matter intake per animal which is also taking the recorded dry exterenal conentrate into account
  • the total cost to feed the pen
  • milk weight produced by the selected pens
  • milk revenue per day with milk prices recorded
  • margin per animal based on the feed cost and milk revenue
  • the total cost to feed the pen
  • the Dry Matter Efficiency. Using the filter option allows you to calculated the DME over all animals or only the milk producing pens.
Time range: The selected time range is given here. It is possible to change the time range by clicking the time range, make changes and apply
Create preset: When a selected time range and or properties combination will be applied repeatedly, this can be saved as a preset using this button. The preset will be saved with a name you can enter yourself. It is possible to edit the preset in the preset area using the details button.
Select preset: When you’ve already created presets, this will enable you to choose from the previously created presets
Download: With this button the report preview will be downloaded to a file.
Properties (gear icon): This will enable you to customize the report. This is possible using different tabs:

General: 
  • Max trend: The percentage entered here is used to show when the trend in DME between days is higher or lower than the set max trend.
  • Show DME (ECM or FPCM): it is possible to show or hide the DME (ECM/FPCM) data on the report. This is only relevant to display if fat and protein are available. 
  • Show fat and protein: it is possible to show or hide fat and protein on the report. This is only relevant to display if fat and protein are processed or entered. 
Pens: Only the data of selected pens will be used for calculation of data on the report. 
Pen types: Only the data of selected pen types will be used for calculation of data on the report.

Report data:
  • Date: the date the specified pens were fed
  • Dry weight: the dry delivered weight that was delivered to the pens
  • Dry refusal: if refusal is registered, then dry refusal is displayed here
  • Dry external concentrate: this is the dry external concentrate. A fixed dry matter of 80% is used to calculate the dry external concentrate value.
  • #Animals: shows the number of animals that were fed that day in the selected pens.
  • DMI /  Animal: the Dry Matter Intake per animal based on the amount of dry feed, dry external concentrated delivered and the amount of dry weighback that was registered for that day.
  • Feed cost (currency): This shows how much it cost you to feed your animals for that specific day.  
  • Milk weight: milk weight produced by the selected pens (using the Link add-on it is possible to import milk weight data of specific Herd Management Systems).
  • Milk revenue (currency): In order for TAP FEED to calculate the milk revenue, the milk price needs to be recorded (using the Link add-on it is possible to import the milk price data of specific Herd Management Systems).
  • Margin / Animal (currency): This shows you how much you make off of each cow per day.  Take the milk revenue minus the feed cost divided by the number of animals.
  • Feed cost per 100 (unit): In order to get the cost/100 (kg/lbs) milk, you need to have milk weights populated (either through herd management software or manually).  Take the cost and divide it by the milk wt. then multiply by 100 
  • DME: Dry Matter Efficiency measures the production efficiency of converting dietary inputs into milk. The milk weight divided by the dry weights.

  • DME (ECM/FPCM): This column is only visible when 'Show DME (ECM/FPCM) with properties is ticked. For each of the two options, the formula is shown below.  
    • The Energy Corrected Milk (ECM) formula is used with unit system is set to 'Standard (US)'ECM = (0.327 * Milk Pounds) + (12.95 * Fat Pounds) + (7.2 * Protein Pounds) 
    • The Fat-Protein Corrected Milk (FPCM) formula is used with unit system set to 'Metric' or 'Imperial'. FPCM = (0.337 + 0.116 * Fat% + 0.06 * Protein%) * Kg Milk 
  • % Fat: this is the % fat recorded with the milk production. This can be entered manually but using the Link add-on it is possible to import this data of specific Herd Management Systems
  • % Protein: this is the % protein recorded with the milk production. This can be entered manually but using the Link add-on it is possible to import this data of specific Herd Management Systems

Weighted average:
The weighted averages over the selected period. If the last day does not have milk production yet, make sure to exclude this day from the report to have the correct calculated averages.
