  1. Ceftiofur data from NARMS was not available, therefore, no validation analysis was done. Where the bias/difference is positive, ARIMA predicted values exceeded the NARMS-reported data. Wherever the P-value > 0.05, the average bias/difference was not statistically significant different from zero, therefore, the ARIMA predictions were not statistically different from the NARMS-reported data
