Database median
3780.0% of 325 reports involved a death outcome. Read alongside breed popularity, veterinary access, and owner awareness — these shape how many events ever reach the FDA. The 12% comparison line is the rough cross-breed median in the FDA CVM database; values above suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Jersey Pet Health Insights
Across the FDA Center for Veterinary Medicine adverse event database, Jersey accounts for 325 submitted reports and currently ranks #163 by report volume within the cattle population. Of those reports, 123 involved a death outcome — a 3780.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 1.7 years, with an average recorded body weight of 231.2 kg (509.8 lbs). These figures reflect the voluntary reporting pool only and should be read alongside breed popularity, veterinary access, and owner awareness — all of which shape how many events ever reach the FDA.
The most frequently reported clinical signs for Jersey are Death (93 reports), Lack of efficacy - NOS (37 reports), Lack of efficacy (bacteria) - NOS (22 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Monensin Sodium appears in 90 reports and is the single most-referenced drug, followed by Sometribove (30) and Ceftiofur Hydrochloride (24). Counts like these surface which therapeutic classes dominate the reporting stream — useful context when comparing reactions across breeds of the same cattle species.
Outcome coding on the 371 reports with a recorded status is dominated by Outcome Unknown (41.5% of coded outcomes). Annual submission volume ranges from 2,010 to 2,025 reports across the 16 years on file, indicating the reporting trend is shaped as much by awareness cycles as by underlying clinical events. Because FDA adverse event reports describe correlation rather than causation, these numbers are most useful as a signal of where to ask further questions with a veterinarian — not as a standalone risk score for any individual cattle.
Understanding Jersey Adverse Event Data
Jersey has 325 adverse event reports on file. Lower report volumes may reflect a less common breed, lower reporting rates, or genuinely fewer adverse events.
The 3780.0% death rate is above average, though this statistic should be interpreted cautiously. Death reports may be overrepresented because serious outcomes are more likely to be reported than mild reactions.
The most frequently referenced drug in adverse reports is Monensin Sodium, appearing in 90 reports. This may indicate widespread use of the medication rather than a specific safety concern for Jersey.
