Petermann et al.Automatic milking systems: Udderhealth and milk flow profilesM. Petermann 1 , W. Wolter 2 , C. Rittershaus 1 ,B. Kloppert 2 , H. Seufert 1 & M. Zschöck 21Institut für Landtechnik, Justus-Liebig-UniversitätGiessen, Braugasse 7, 35390 Giessen, Germany,E-mail: Christiane.Koetting@agrar.uni-giessen.de2Staatliches Medizinal-, Lebensmittel- undVeterinäruntersuchungsamt Mittelhessen, 35396Giessen, GermanyAutomatic milking systems (AMS) enable voluntary milking up to morethan three times a day. This fact should not only increase the milk yieldbut also improve the status of udder health in automatically milked herds.The aim of the present study was the investigation of udder health andmilk flow profiles and possible relations between these parameters. Datawere collected on two practical farms using single-box-systems. One herdhad 70 dairy cows which have been milked by one AMS, the other herdhad a stock of 110 dairy cows and used two AMS. Over a period of sixmonths both herds were examined three times. This investigations includeantiseptical foremilk-samples for bacteriological analyses and the recordingof milk flow profiles. Environment-associated pathogens had been the maincause for subclinical mastitis. In one herd the incidence increased duringthe period of investigation. But also udderassociated (contagious)pathogens can spread out in an automatically milked herd. Subclinicalinfected quarters in average have a higher maximum milk flow and longerovermilking times.SummaryKey words: Automatic milking systems, ,udder health, somatic cell count, milkflow profiles, management.One of the most important technological innovations in dairying duringthe last years is automatic milking. Worldwide more than 1000 dairy farmsare using this new technique. Most of the systems used in Europe areinstalled in family farms with 50-150 dairy cows. Beside the reduction ofphysical labour and the free organisation of working processes animprovement of the udder health status is suggested, because automaticmilking systems enable voluntary milking and some systems are allowinga quarter milk flow controlled milking process.IntroductionICAR Technical Series - No 7181
Udder health and milk low profilesAim of the study is the investigation of quarter milk flow profiles, somaticcell count, bacteriological status and possible relations between theseparameters. The examination is taking place in two dairy farms, one with70 dairy cows and one AMS (herd 1), the other with 110 dairy cows andtwo AMS (herd 2). Both farms are using single-box–systems.Material andmethodsDuring the milking process single quarter milk flow profiles were recordedwith the Lacto Corder R (by Foss), which measures total amount of milk,rate of maximum milk flow, overmilking time and total time of milk flow.At the same time single quarter foremilk-samples were taken antisepticallyfrom all lactating cows directly before the milking process started. Thesomatic cell count of each sample was determined by fluorescence-opticalmethod (Fossomatic R 360). According to the somatic cell count the quarterforemilk samples were subdivided into two groups. Samples with a somaticcell count up to 100 000 cells/ml were classified as samples from healthyquarters. Samples with more than 100 000 cells/ml were suspected to comefrom quarters with subclinical mastitis (1). These samples were culturedfor bacteriological examination according to IDF standard (2). Each herdwas at least investigated three times in intervals of three months.ResultsThe herds were free of Streptococcus agalactiae, and only a few quarterswere found to be infected with Staphylococcus aureus (
