Use of Probiotic <i>Bacillus megaterium</i> NCH 55 for Treatment of Subclinical Mastitis in Cows – Preliminary Study

Abstract The development and implementation of new safe means treating subclinical mastitis (SM) in the production process remains a pressing problem. Our study aimed to investigate therapeutic effect Bacillus megaterium NCH 55 strain on cow SM. All animals with signs SM were fed basic diet probiotic’s addition 15 g/per day. experiment was conveyed 30 consecutive days. Milk blood collected 7 th , day experiment. Daily milk yield increased by 32.2% somatic cell count decreased from 290.00±32.12 96.80±39.03 ths/cm 3 . A decrease inflammation indicated POM 370 (by 2.2 times) 430 2.8 times). No significant changes serum indices cows observed. positive has been established treatment probiotic B. NСH can be considered as an alternative antibiotics other chemotherapeutic drugs for cows.
