| Thirty-four dairy farms in the south central zone of Chile were evaluated in order to describe the functioning of the milking machines with respect to vacuum, pulsators, milklines and cluster characteristics and their relationship with somatic cell count (SCC) and milk yield (MY). An inadequate nominal vacuum level (NVL) was one factor that influenced negatively SCC. The increase of SCC was more accentuated in those milking machines with high-lines than mid- and low-lines. MY was also negatively influenced by an inadequate high NVL. Higher MY value was found in those farms which had < 44 kPa NVL. In all cases, effective vacuum reserve deficit (EVRD) produced SCC above international recommendations. The EVRD effect was not significant (P > 0.05) on... |
