The effectiveness of teat and udder cleaning as performed by the Astronaut robotic milking system.
On behalf of the Faculty of Veterinary Science of the Utrecht University and Lely Industries N.V. at Maassluis a study has been conducted into the effectiveness of teat and udder cleaning as performed by the Astronaut robotic milking system. Cleaning of teats and udders before milking also effects the overall image of hygiene in food production, because teat and udder surfaces are among the main sources of bacteria in raw milk. A new law as well as upgraded rules for automatic udder cleaning will soon become operative. Means for instant control of the effectiveness of teat and udder cleaning are not available and for that reason appropriate cleaning should be ensured at all times.
The effect of brushing frequency on the efficiency of teat cleaning also formed part of the research, whilst the results of disinfection by the brushes were measured as well. In addition, efforts were made to establish a relationship between milk quality and udder cleanliness. On the grounds of conductivity, an essential milk quality parameter, no such connection was ascertained. Finally, iodine spraying after milking was also evaluated within the framework of this study.
Most interesting of all is the final conclusion: This research confirms that the Lely Astronaut milking robot meets the requirements that will come into effect in Europe.
