Implication

FMD outbreaks may reduce yields in early-lactation older cows; leaves open mitigation strategies pending interventional studies.

Structured PICO

P
Population
218 lactating mainly European-breed cattle on a large-scale dairy farm in Kenya analyzed to estimate the impact of an FMD outbreak on milk yield.
E
Exposure
Foot-and-mouth disease (FMD) outbreak due to serotype SAT2 virus
C
Comparator
Predicted yields based on historic data from the same herd
O
Outcome
Milk yield (kg per cow) up to 305 days lactation

Main Result

Mean Difference: -688.7 (95% CI -981.8–-395.5)

Foot-and-mouth disease outbreaks significantly reduce milk production in dairy cattle, particularly in older animals early in lactation.

Limitations

  • Generalisation of the results requires caution as the majority of Kenyan milk is produced in smallholder farms.

Cite This Study

Lyons et al. (2015) conducted an observational in Foot-and-mouth disease (FMD) (n=218). Foot-and-mouth disease (FMD) outbreak vs. Predicted yields based on historic data from the same herd was evaluated on Milk yield up to 305 days lactation (688.7 kg less milk, 95% CI 395.5-981.8). An FMD outbreak in a dairy herd resulted in early-lactation, older cows producing on average 688.7 kg (95% CI 395.5-981.8) less milk than predicted for their remaining lactation.
