Effect of two milking systems on teatConclusionsMilking systems with different levels of milking vacuum gave the samelevel of TH, colour and texture. This study unlike other studies comparedmilking systems under the same milking and herd management over acomplete lactation. Differences in teat condition were shown wherepost-milking disinfecting was omitted, with front teats as compared torear teats and stage of lactation. When teat condition is used to evaluatemilking systems, stage of cluster removal, lactation days and post-milkingdisinfection should be considered. Machine yield and peak milk flow-rateobtained with specific types of milking units is effected by the magnitudeof the milk yield per cow per milking.ReferencesHillerton, J.E., I.
