Abstract

Abstract The Total Bacterial Count (TBC) and the Somatic Cells Count (SCC) in the milk are important indicators of its hygiene and quality. Hygienic conditions in barns, milking procedures, udder hygiene before, during and after milking, milking machine hygiene, as well as milk cooling procedures immediately after milking, have direct or indirect influences on milk hygiene indicators. Poor results of milk hygiene quality, when it comes to SCC and TBC, which are often seen in dairy cattle farms in our country, indicate numerous omissions before and during milking. To determine the possibility of improving milk hygiene quality, training of extension service professionals and farmers was conducted, corrective and preventive measures were determined and the achieved state was monitored on 128 dairy farms where SCC and TBC were observed at regular monthly intervals for 6 months. The results showed a continuous statistically very significant improvement in hygienic conditions in barns, milking procedures, udder hygiene before, during and after milking, milking machine hygiene, as well as milk cooling procedures. This has contributed to a statistically very significant improvement in the hygienic quality of milk, both in SCC and TBC indicators, continuously from month to month, with a visible improvement at the end related to the beginning of the study period. At the begining and the end of survey 19.7% and 50.0% of milk samples belong to 1st class of milk quality, respectively, indicating a significant improvement after implementation of corrective measurements.

通过系统实施预防和纠正措施改善卫生习惯和牛奶卫生

摘要牛奶中的细菌总数（TBC）和体细胞计数（SCC）是衡量牛奶卫生和质量的重要指标。谷仓的卫生条件、挤奶程序、挤奶前、挤奶期间和挤奶后的乳房卫生、挤奶机卫生以及挤奶后立即冷却牛奶的程序对牛奶卫生指标有直接或间接的影响。我国奶牛场常见的SCC和TBC，其牛奶卫生质量不佳，表明挤奶前和挤奶过程中存在许多疏漏。为了确定改善牛奶卫生质量的可能性，对推广服务专业人员和农民进行了培训，确定了纠正和预防措施，并对128个奶牛场的实现状态进行了监测，这些奶牛场每月定期观察SCC和TBC，为期6个月。结果显示，谷仓的卫生条件、挤奶程序、挤奶前、挤奶中和挤奶后的乳房卫生、挤奶机卫生以及牛奶冷却程序在统计上持续得到显著改善。这有助于牛奶的卫生质量，无论是SCC还是TBC指标，逐月持续地得到统计上非常显著的改善，在研究期结束时也有明显的改善。在调查开始和结束时，19.7%和50.0%的牛奶样本属于第一类牛奶质量，这表明在实施纠正措施后有了显著改善。
