ANALYSIS OF FEED CONVERSION – as a unit of nutrition and animal health
The analysis of feed conversion is carried out on the basis of the results of the milk yield test, taking into account nutritional health disorders. Signal values were determined for the combination of characteristics of the milk constituents fat and protein as well as for lactose, which, depending on the amount of milk and the stage of lactation, indicate suspicion of metabolic disorders or suspicion of diseases.

Farm | usually overall operation, alternatively evaluate BU separately
Period | for smaller farms, it is advisable to select over a longer period of time
MRec from … | MRec by company or BU
Start | calculate the analysis
Lactation | selectable according to 1st lact, 2nd lact., 3rd lact, combination possible
Display of the MRec, collapse with or expand with 
With drag’n’drop, the display can be individually adapted to your own needs.
By clicking on the overview, the individual animals are listed in detail, which are classified in the class (vertical 1-6) and in the lactation section (1-4). The display of the animals can also be deselected or displayed
The animals that cannot be assigned to classes 1-5 are considered Unobtrusive. They are considered “healthy” (slang)
In the analysis display on the right, all key figures are displayed with their percentage occurrence in the lactation section (LS) or total.
When analyzing over a period of time, the “Previous Month” and “Deep Analysis” feature is not available.
When analyzing over a period of time, the Deep Analysis feature is not available.
In the detailed analysis, the animals are subdivided more delicately within the class
General principles:
- The feed ration must be adapted to the different requirements in the lactation periods.
- The composition of the feeding groups must comply with this principle.
- Conspicuous animals must be printed out and the nutritional and health status on site must be assessed.
The following priorities are set in the assignment to the feed conversion groups in the lactation periods:
highest priority … until… 
lowest priority
1-30 days
31-100 days
101-200 days

1 to 30 days of lactation: according to the overview (from top to bottom)
31 to 100 and 101 to 200 lactation days:
- insufficient energy and nutrient supply
- Lack of energy
- Structural deficiencies
- (excessive body fat accumulation)
- lactose levels that are too low
>= 201 lactation days: according to the overview (from top to bottom)
This methodology was developed by a working group of feed experts from the state control associations with the significant cooperation of Dr. Reelitz and Prof. Rossow. Also involved were: Dr. Nagel, Dr. Kesting (LKV Mecklenburg-Vorpommern), Dr. Lemme (LKV for Performance and Quality Testing Saxony-Anhalt), Dr. Keusenhoff (Thuringian Association for Performance and Quality Testing), Dr. Richardt (LKV Saxony), Ms. Ulber (VIT-PCS), Dr. Feucker (VIT-PCS / DSP).
