Dynamic tests are performed when cows are being milked. The main aim is to measure vacuum fluctuations at the teat end which may not always be suggested as a problem by the results of the static test. Milk flow can also be measured which may reveal problems with bimodal milk flow, suggestive of problems with udder preparation and/or milk let down. It is during such tests that ‘’’liner slip’’’ may be noticed. | Dynamic tests are performed when cows are being milked.
