摘要：

On an experimental farm 3 dairy breeds were compared with regard to mastitis by various parameters. Higher cell counts and more udder infections were present in the Dutch Red and White (DRW) in comparison with the Holstein Friesian (HF) and the Dutch Friesian (DF). Within the HF breed a negative correlation between cell count and production was established and also in this breed, a negative correlation between maximum rate of milk flow and cell count. There is no evidence that higher procuction and easier milking are connected with more mastitis. On the contrary, within the breeds an opposite trend appeared. Selection against mastitis does not conflict with selection for production and ease of milking. An addition trial revealed that sampling after too quick preparation of the cows before milking resulted in much higher cell counts in quarter samples. Cows which were selected for drying off with antibiotics recovered from their infection but these more susceptible animals maintained a higher cell count to a certain extent. © 1979 Taylor & Francis Group, LLC.
