Stall side method for the detection of bacteria in dairy cattle

A method for determining amounts of bacteria in bovine milk comprising the steps of:

• i) Contacting the bovine milk with a material which selectively attracts bacteria
• ii) Separating the bacteria from the material and placing the bacteria into solution
• iii) Treatment of the bacterial solution with a bacterial releasing agent capable of lysing bacterial cells to give a released ATP second solution
• iv) Treatment of the second solution with a Luciferin/Luciferase reagent to give a third solution and
• v) Quantitation of bacteria in the third solution by luminescence;
