„The main sectorof livestock production is rearing of dairy cows in most of EU countries and also in the Czech Republic (CR). The measures implemented to reduce inflammation in the mammary gland of cows can improve the less satisfactory long-term economic results in many herds in the CR milk production. Higher mastitis incidence usually has the effect of increasing of costs on cow rearing and a decline in revenue from sale of inferior milk quality (Kossaibati and
Esslemont, 1997; Rüsch, 2000; Walkenhorst, 2000; Krömker, 2007; Jones and Bailey, 2009; Nielsen, 2009; Hogeveen et al., 2011; Lührmann, 2013; Kvapilik et al., 2014). Inter alia, this also follows from the results of analyzes of bulk milk samples
originating from farms included in the project „“Research, new products and services to create and the center of prevention detection and support of mastitis treatment „“(QJ1210301). According to Zschöch (2016), it is not possible to replace it
successfully the analytical results of the quarter milk samples by results of bulk samples in terms of checking of cow mammary gland health. However, it is possible to assess the impact of the identified quality indicators of milk on its price
by more reliable way. Therefore, the aim of this paper was to analyze the results of the monthly obtained bulk samples and their use how to estimate their impact on the purchase milk price.“
