Abstract:
The biodiversity of the mountain meadows together with the climatic factors of the Dorna region ensure high-quality
milk favorable for obtaining traditional dairy products that are in great demand. The present research aimed to analyze
the correlative evolution of some climatic factors and hygienic-sanitary parameters of several milk samples obtained
from cows raised in the Dorna area. This study was carried out between December 2019 and November 2020 and aimed
to evaluate the influence of seasonal fluctuations of climatic factors on the sanitary parameters of raw milk from
households and commercial dairy farms in the Dorna region (southwest Bucovina-Suceava county). In this regard, we
collaborated with two weather stations, which provided us with information on the fluctuations of temperature,
humidity, precipitation, and atmospheric pressure by season. These aspects were correlated with the evolution of TBC
(total bacteria count) and SCC (somatic cell count) values obtained when investigating some raw milk samples (n=30),
and the obtained data were statistically analyzed. The results revealed more or less relevant seasonal influences of the
investigated climatic factors on the hygienic-sanitary quality of the analyzed raw milk. Of these, we mention the
recording of higher values in winter and lower in summer for TBC, and higher in autumn and lower in spring and
summer for SCC respectively, but within the EU standards.
