Effect of AM on animal behaviourFigure 2. Estimated milk yield by assumed milking intervals.The calculated milk yield curves assume a consistent milking interval overthe course of the lactation. For a realistic estimate, the actual visitingperformance of the cow is more important. These evaluations are plannedon the basis of the available data, supplemented with future data. Theinfluence of multiple milking on the content of the milk must also beclarified.ReferenceArtmann, R., E. Bohlsen, K. Knappstein & J.

BarthEvaluation of somatic cell count underautomatic milking conditionsK. BarthInstitute of Physiology, FML, TU Weihenstephan,Weihenstephaner Berg 3, D – 85354 Freising., GermanyE-mail: Kerstin.Barth@t-online.deInvestigations under standardised conditions (6 cows, milked and sampledfor 16 days with varied milking interval, MI) showed, that increasing MIof 4, 8 and 12 hours lead to decreasing somatic cell count (SCC) of 499, 360and 297 cells per ml (P≤ 0,016), respectively. In contrast to our study, someauthors observed increasing SCC with MI if cows were sampled inautomatic milking systems. Further investigations in herds milkedautomatically confirmed both observations. SCC increased with increasingMI per herd, as determined by the management program. By contrast SCCdecreased if it is evaluated per cow. The relationship between subclinicalmastitis, lowered milk yield and yield based MI explains the differences.SummaryKey words: Milking interval, somatic cell count, mastitis detection.Milk recording under robotic milking conditions collects milk samplesafter different MI. It is known that this must be taken into account for theevaluation of some milk constituents. SCC of milk is an establishedparameter to supervise udder health, its analysis in monthly recorded milksamples is common practice. Thus the affection of SCC by MI gains newimportance.IntroductionInvestigations were carried out under standardised conventional as wellas under robotic milking conditions.6 cows were milked and sampled in a stanchion barn over a period of16 days in two trials (8 days each). MI were 4:8:12 and 8:4:12 hours,respectively. Quarter milk samples were analysed for SCC. Methods ofmilking and sampling are already described elsewhere [1].Material andmethodsICAR Technical Series - No 7165
