NIR feed intake check
IT is possible to identify which cows in a dairy herd are most efficient using NIR technology, which is more commonly used for silage analysis.
Phil Garnsworthy of the University of Nottingham said that scanning cows faeces gave a much better indication of a cows feed intake of forage or a mixed diet than measuring the feed.
It is easy to measure output of milk yield, but more difficult to measure feed intake on farm. The prediction using NIR is 80-100% accurate, and is most accurate for forage alone. But it requires access to a correctly calibrated NIR machine, only currently available at Nottingham.
