The probability of clinical mastitis in the next lactation month for teatends with no (N), thin (A), moderate (B), thick (C) and extreme thick (D) smooth(g) and rough ( ) callosity rings.Pointed teat ends had higher TECT and TECR scores than flat or invertedteat ends. TECT and TECR increased by 0.11 score points and 9 %,respectively, per 10 kg higher daily milk yield at peak production.Neijenhuis, F., H. W. Barkema, H.

Box 43, NL-6700 AA Wageningen, The NetherlandsThe Research Institute for Animal Husbandry in Lelystad and the IMAGinstitute in Wageningen have combined their milking machine researchin the Dutch Expertise Group Machine Milking. The Expertise Groupfocuses on generating knowledge on the milking process. Improvementand fine-tuning of the milking process are key-issues. One of the researchtopics is liner research. On request of a milking machine manufacturer,two liners with the same type and dimensions, but different compounds,were compared with regard to milking time, average and maximum milkflow and teat end deformation.SummaryKey words: Milking characteristics, liners, milking, teat condition, teat enddeformationThe tests were carried out at the experimental station “De Vijf Roeden” ofIMAG-DLO at Duiven in 1998. The milking parlour is equipped with aquarter milking installation for each stall including facilities for accuraterecording of the milk evacuation process per quarter. Machine milkingparameters are adjustable per stall (milking and pulsation vacuum) or perquarter (pulsation rate and ratio). Switch off levels are adjustable per stall(udder) as well as per quarter. Teat end deformation is measured with a200 VET scanner with a linear Array 7.5 MHz probe ultrasound scanner200 VET, Pie Medical (Neijenhuis, submitted). For best probe application,the presence of air between probe and tissue examined must be avoided.Therefore the teat was immersed into water in a plastic bag and the probewith sufficient contact jelly was held against the bag. The water used hada temperature of approximately 35 ºC. The scanning device was connectedto a computer. The real time scanning was shown on the terminal of thescanning device. When the picture of the teat was satisfying, the picturewas frozen and exported to the PC. The measurements on the image ofMaterials andmethodICAR Technical Series - No 7203
