摘要: The aim of this study was to describe the frequency distribution ewes in SCC groups on basis SCS (somatic cells score) per lactation and estimate changes from 1st 2nd lactation. experiment carried at seven farms observed period (2016 2017) eight one (2017 2018). Within each periods same animals were sampled their following next year study, only. Totally 1199 milk samples 159 1653 219 collected during period, respectively. Milk sampling taken monthly April August both periods. For evaluation only with minimum three (minimum six animal) included within divided into five lactation: G1 = <200 × 103 cells.mL-1, G2 ≥200 <400 G3 ≥400 <600 G4 ≥600 <1000 cells.mL-1 G5 ≥1000 cells.mL-1. In total statistically significant impact parity detected (p <0.0001) From farm point view two effect found out. Thus some no increase first second observed. When comparing periods, 6.92% 10.96%, respectively moved group G5. management demonstrated.
