Cancellation of April ring test – May ring test running

Posted 2 April 2020

Due to the current Covid 19 pandemia,workers in Belgium have to stay at home as much as possible and reduce their work to the legal mandatory aspects. As MIR standardization is not a legal obligation, the CRAW milk laboratory cannot produce the April standardization set. Thus, you will not receive any ring test samples for April. May ring test samples will be send normally.

We hope you are feeling helathy as well as your relatives, and hope to see you safe and sound soon.

STANDARDISATION OF MIR SPECTROMETERS ACROSS OPTIMIR NETWORK

The triple objective is to obtain similar spectra overtime, across models of machine, and across brands of machine. The network is comprised with around 65 MIR spectrometers in 25 milk laboratories.

We’ve proven that the standardisation of machines is mandatory :

To constitute a common database with spectral data from different sources.
To develop equations or models able to be applied on every machines of the network.
Example: a University has built a model by using non-standardized spectra. This model is accurate only on the machine that the University used, and as soon as no disturbances
To obtain the right predictions on every machine of the network whatever the brand or model of spectrometers, and whatever the disturbances over time.
Example: a MRO utilises non-standardized spectra to get predicted values from an OptiMIR equations ⇒ the predicted values obtained are completely wrong.

The OptiMIR network involves Milk Recording Organisations and Research Partners. It’s an innovative framework for the development of dairy farm management tools based on MIR technology.

OPTIMIR MODELS AND EQUATIONS

Available predictive equations (2015) :

Milk concentrations of Ca, P, Na, K, Mg
Milk concentrations of Fatty Acids (e.g. C10, C12, C14, C18:1cis9…)
Milk concentrations of BHB, Acetone and Citrate
Methane emissions
Warning indicator of sub-clinical ketosis based on milk BHB and Acetone

Predictive equation in progress and expected soon :

Warning indicator of energy deficit based on milk BHB, Acetone, Citrate, C10, C12, C14 and C18:1cisC9
Warning indicator of sub-clinical ketosis based on spectral variations
Warning indicator of disturbed energy balance based on spectral variations

Predictive equation in progress and expected in longer term :

Pregnancy monitoring tool based on spectral variations
Warning indicator of sub-clinical acidosis based on spectral variations
Warning indicator of disturbed energy balance based on spectral variations
