Adequate post milk teat disinfection can be assessed visually in the parlour as part of a mastitis investigation. This would include an assessment of teat coverage and time to application. However, the operator may modify their technique when being critically observed. As an indirect assessment of teat coverage, the volume of product used over a period of time can be measured to inform an approximate judgement (e.g. A herd has 100 cows in milk, milked twice daily and is performing teat dipping. A 200 litre barrel of product should be able to dip (200 x 1000/10) 20,000 cows. In this herd, 200 cows are being dipped per day. Therefore a 200 litre barrel should last (20,000/200) 100 days or just over three months).
