SSC under automatic milking conditions120100SCC [1,000/ml]806040200short intermediate longRank of milking intervalFigure 3. Mean and 95% interval of confidence of SCC for ranked milking intervalsbefore quarter milk sampling in a milking parlour (176 quarters of 44 cows).5040Frequency3020100< 6 < 7 < 8 < 9 < 10 < 11
Barthyield is often a side effect of subclinical mastitis. Therefore, cows withsubclinical mastitis (and higher SCC compared to healthy cows in the sameherd) were milked in longer intervals. Figure 4 shows the distribution ofhealthy and disturbed quarters based on the defined MI classes. Obviously,the major part of mastitis quarters was milked after more than 10 hours.Increasing MI causes decreasing SCC readings. The reported increase ofSCC connected with wider MI under robotic milking conditions is nocontradiction. Mastitis is often accompanied by a lowered milk yield.Therefore, mastitis cows usually get longer MI from the managementprogram. This gives the impression that SCC increases with MI. Scientificinvestigations concerning udder health in herds milked automaticallyshould take into account that correct data must be based on MI withincow or quarter to avoid false conclusions.ConclusionsThe study was funded by H.
