A reliable determination of milk components is not only important for setting the milk price for the farmer, it is also an essential part of milk recording activities related to animal breeding. Near-Infrared-(NIR) Analysis in conventional laboratories has been established for many years. Although efficiency of analytical procedures and speed of data transmission have been considerably improved in recent years, it still may take on average two days before the results of milk analysis arrive at the farmer.

For some aspects of herd management, e.g. as far as evaluation of udder health is concerned, a shorter delay would be interesting. Therefore for some years solutions for on farm milk analysis are discussed, which would be interesting not only for milk recording purposes (no transport of samples to a laboratory required any more) but would also allow a more efficient herd management.

A milestone on the way to installing those facilities is a project which was initiated about 25 years ago by the French milk recording organisation France ContrÃ´le Laitier (FCL). The first real device, presented in 1986, prepared dried droplets of milk, to be analysed by a NIR-system. The final step up to now was the application on a national level of several prototypes of a system based on a NIR-analyser which was to be linked by fibre optics to up to 12 sensor units, installed in milking parlours.

One of the prototypes of the FCL-system was recently tested at the experimental farm of FAL at Braunschweig, Germany. It was found that the results for fat, protein and lactose, produced by this system, corresponded within a bias +/- 0,05% with the results obtained by a reference laboratory of the local milk recording organisation.

Meanwhile some other devices for on-farm milk analysis are known to be on the market or close to being presented.

It can be expected that this technology will be helpful for the farmer, especially with respect to optimisation of cow feeding and perhaps for early detection of mastitis, but it will also change the profiles of activity of central milk analysing laboratories. Probably the amount of routine analyses will be reduced, but with some certainty there will be a resulting additional demand for evaluating the performance of on farm installations.
