The impact of somatic cell count on milk yield and composition

Highlights

  • Mastitis mainly health problem of udder of dairy animals affecting economy of milk production and its quality and hygienic safety (Leitner et al, 2008; Tvarožková et al, 2019, review)

  • 3 Results and discussion At the level of regular milk recording test days we did not find out significant impact somatic cells counts (SCC) on milk yield, but was observed numerically decline in milk yield (290.8 ±7.19 ml, 260.5 ±10.19 ml resp.) in relation with increase of SCC (SCC

  • The stage of lactation had the impact on the decrease of milk yield in study published by Oravcová et al (2020).In content of fat we did not find out change regarding to the SCC groups

Summary

Introduction

Mastitis mainly health problem of udder of dairy animals affecting economy of milk production and its quality and hygienic safety (Leitner et al, 2008; Tvarožková et al, 2019, review). This disease causes high economic looses due to decline milk yield and change milk composition (Oravcová et al, 2018; Paschino et al, 2019). The limit of SCC >500 × 103 cells/ml was determined by Sutera et al (2018) as indicator in relation to change in milk quality. The aim of the work was to clarify the effect of different levels of SCC on milk yield and its composition at the level of test day and at the level of whole lactation
