Milking Routine The Effect of Interval Dip on Milking Clusters

BACTERIAL COUNT EVALUATION WAS MADE IN THE NIPPLE TAPES INTERMEDIATELY DIPPED WITH PERACETIC ACID SOLUTIONS.

It is known that milking clusters are effective in the transmission of mastitis pathogens from cow to cow. Scientific research has shown that after an infected cow is milked, the next 6 to 8 cows are at risk after milking with the same milking clusters. Especially the first 1st and 2nd animals are at very high risk of contamination.

Interval dips after each milking before attaching the milking clusters to the other animal is a very effective method that reduces the risk of mastitis by killing existing pathogens

Peracetic acid is an effective tool especially in the sterilization of milking clusters.

APPLIED METHOD

It is an application performed to evaluate bacterial loads on the inner surface of milking clusters before and after peracetic acid application

Manual application, semi-automatic and fully automatic application

Swabs were taken after the milking of the selected 30 cows was completed and the milking clusters were removed from the udder.
Swabs were taken from the inner surface of the milking clusters, which were interval dipped with peracetic acid solution at a concentration of 0.5% (250 ppm), before and after intermediate dipping.
Milking clusters with peracetic acid solution for 3 seconds. 10 seconds after treatment. After waiting for it to filter, the swab was taken.
