Kirchnerová & Foltys• 10 samples for determination of fat by Röse-Gottlieb, and protein byKjeldahl;• 10 samples for polarimetric determination of lactose;• 10 samples for somatic cells counting by Fossomatic 90.After the performing of analyses, the results in duplicates were reportedon the appropriate report sheets and returned to CECALAIT. The resultsof the statistical data treatment (analysis of the laboratory’s repeatabilityand accuracy) were sent anonymously to each participating laboratory,knowing only his identification number. As the reference values were takenthe average values of 10 - 15 laboratories after elimination of extremes byGrubbs test at 5 % level.Statistical treatment of the results concerning proficiency interlaboratorystudy is shown in table 1. Limit for Euclidian distance D define anacceptability area of the laboratory performances. Comparison of Marchand September RIAP laboratory D-value with IDF limit for used methodsshows the step-by-step improvement of analytical practices. Septemberdifferences between the reference mean and laboratory mean (∆), are forevery method not higher than 0.5 g/kg for milk composition and 20x10 3 /mlfor somatic cells count.ResultsAt the presentation on poster will be shown the graphical evaluation ofaccuracy.ICAR Technical Series - No 7251
Botto et al.Effect of ultrasound in circulardisinfection of milking equipmentL. Botto, S. Mihina & V. FoltysResearch Institute of Animal Production, Hlohovská 2,949 92 Nitra, Slovak RepublicE-mail: botto@vuzv.skThe effects of circular cleaning of the pipeline milking equipment ZD 2-020by means of ultrasound and its influence on the cleanness of milking unitswere evaluated.Aim, materialand methodsThe results were compared with the effects of the traditional way ofsanitation. An ultrasonic cleaning equipment with a small trough wasconstructed for this purpose (Figure 1).1 - Ultrasonic generator,2 - Ultrasonic trough,3 - Underwater ultrasonic emitters,4 - Drain outlet,5 - Control panel,6 - Box for distance control,7 - Time relay,8 - Acoustic alarm of failure,9 - Carrier-frequency cables,10 - Ground cable,11 - Milking setFigure 1.
