What are the Nutritional Value modules?

Mold Risk Module (FVI)
The Mold Risk (FVI) module analyzes the temperature history of your hay to estimate the impact of heating on forage quality. Instead of relying solely on the smell or appearance of the hay, you can detect batches that may pose a risk more quickly. With the Mold Risk (FVI) module, you can:
- Detect signs of overheating early.
- Identify risk areas within haystacks.
- Identify the batches to be distributed as a priority.
- Contribute to a healthier diet for your herd


Hay Composition Module
The Hay Composition module estimates the main indicators of the nutritional value of your hay based on its temperature history and the information you provide about your harvest.
You get estimates for:
- Crude Protein (CP): an indicator of the protein content of your forage.
- Neutral Detergent Fibre (NDF): an indicator of fibre content, used to assess the quality of the forage.
These estimates help you to better adapt your herd's diet throughout the storage period.
