Hypothesis
STEC colonization should also be evident in beef cattle with Jejunal Hemorrhage Syndrome (JHS).
Conclusion
The study confirmed that STECs and mycotoxins are part of the disease complex for JHS in beef cattle.
Supporting Evidence
- Beef cattle developed JHS after consuming feed containing mycotoxigenic fungi.
- STECs colonized the mucosa in the hemorrhaged tissues of the cattle.
- A prebiotic treatment was associated with 69% recovery of symptomatic beef calves.
Takeaway
Cattle that ate mouldy feed got sick, and a special treatment helped many of them get better.
Methodology
The study involved observing beef cattle, collecting tissue samples, and testing for pathogens and mycotoxins.
Potential Biases
Potential bias in sample selection from specific feedlots.
Limitations
The study was observational and did not include controlled experiments.
Participant Demographics
Beef cattle from two feedlots in Southern Alberta.
