The levels ofaverage milk flow and of peakflow per quarter had increased and weremore uniform over quarters (Table 2). In most quarters the time recordedfor overmilking was considerably reduced, only quarter “front right” didnot show much difference to session 1. “Flow at take off” and “Strippingyield” were higher than in session 1, but more uniform and still atacceptable levels.The results obtained indicated that milkmeters with an appropriatesensitivity for low rates of milk flow may be helpful for evaluation andadjustment of milking behaviour of AMS. However, to do this efficientlythe manufacturer of the AMS should define suitable procedures.Umstätter, C. & Kaufmann, O. (2001).

Pallas & WendtThe development of udder healthof a dairy cow herd inan automated milking systemS. Pallas 1 & K. Wendt 21Humboldt, Universität zu Berlin, Anistitut für Agrar und StadtökologischeProjekte, Philippstraße 13, Haus 10, 10115 Berlin, GermanyE-mail: solveig_pallas@hotmail.com2Freie Universität Berlin, Department of Veterinary Medicine,Oertzenweg 19 b, 14129 Berlin, GermanyThe influence of an improved hygiene management on udder health ofcows in an automated milking system has been studied. The results arebased on data, which were collected over a period of 17 months. The Farmhad two groups of dairy cows which were divided according to the milkingvariants. The examined cows (about 50) have been milked by a one-boxrobot,produced by Lely. Through the examination period, the udder healthhas clearly improved and stayed steady. With regard to mastitis, thepredictive value of electrical conductivity as the main diagnostic parameterwas compared to the appearance of clots in milk. There was no relationbetween both criteria. It is concluded that brilliant milking hygiene isnecessary and a special udder health examination at regular intervals isneeded.SummaryKey words: Automatic milking, udder health, management, peracetic acid.The expected advantages of milking with a milking robot are the savingof working time, easement of work and improvement of udder health.The improvement of udder health occurs not offhand. With a view on thespecific properties of a milking robot, it is to remark, that, if there are about180 milkings with one milking module per day, a high mastitis risk exists.Special sources of infection are the contact points between udder and robot.At one hand there are the brushes which clean the teats before milkingand on the other hand there are the teatcups. SPOHR (2001) could observethat the new-infection-rate has been decreased from 100 percent to 60percent in herds with mastitis problems under utilisation of peracetic acidIntroductionICAR Technical Series - No 7175
