In this study, we
present the management practices and microbiological quality of a dairy farm
with low bulk tank milk somatic cell count (BTMSCC).
In the mentioned farm, BTMSCC was generally <150,000 cells/mL. BTMSCC per day
and bulk tank milk (BTM) microbiological analysis per week were carried out
during one year. Weekly animal and udder health controls and management
evaluations were performed; the somatic cell counts (SCCs) of the milk samples
collected in only 21 weeks of the year were over 150,000 cells/mL but this value
was never over 320,000 cells/mL in the herd. When the management practices of
the weeks with high BTMSCC were evaluated, negative conditions including changes
of paddocks of the animals and estrus synchronization were detected.
In the samples taken from the milk
collection tank for a total of 22 weeks, microbiological
isolation occurred; the most common
bacterium was Escherichia coli.
Udder hygiene, barn hygiene, the cleanliness of the beddings, the care of the
employees toward their work and personal hygiene, and disinfection of the
milking machines and their maintenance were all very good for the whole year.
During the weekly routine controls, clinical mastitis and teat stenosis were
detected twice and once, respectively; however, in those 3 weeks, BTMSCC
increased in only the week that the teat stenosis was observed.
We observed that, even in farms with
intense precautions, BTMSCC may increase and microbiological growth may
occur in BTM. To ensure that these situations do not become permanent, these
precautions should be applied continuously.
