Comparison of squirting made before or after milking on udder infections.
Within an experimental herd, three groups have been randomly constituted --Control group without squirting --Squirting before milking group --Squirting after milking group. The number of new infections and of persistent infections at the end of the experiment diminishes in the squirting after milking group (Table 1); in this group there were no superinfections (Table 2). The distribution of pathogens is similar for the three groups (Table 3). The results of this experiment are compared with those of three previous squirting experiments done on the same herd (Table 4). The pathogenic and practical signification of these results are discussed.
