Benefits of Supplementation of an Electrolyte Scour Treatment with a Bacillus-Based Direct-Fed Microbial for Calves

摘要

A Bacillus-based direct-fed microbial (DFM), Omni-BosCB?, added to an electrolyte was evaluated as a therapy for scours. Fecal shedding of presumptive Clostridium perfringens at day 7 was reduced in scouring calves treated with electrolyte plus DFM compared to scouring calves treated with electrolyte alone. Total therapeutic treatment costs during the first 2 weeks were significantly reduced by supplementing the electrolyte with the DFM: $18.69 and $21.57 for electrolyte plus DFM and electrolyte treated calves, respectively. Electrolyte treated calves experienced more severe scours than electrolyte plus DFM treated calves as additional therapy with Lactated Ringer’s Solution was only necessary for electrolyte treated calves. The DFM may have other ancillary benefits after supplementation has ended, as evidenced by decreased recurrence of a second scouring event. This is the first report demonstrating efficacy of a DFM used therapeutically for mitigating calf scours. These findings have implications as alternatives to chemical interventions for disease control.
