Table 2.

Effect of the treatment group on clinical score, percentage of retreated animals, percentage of chronic cases, and mortality.

	Clinical score day 0 (Mean ± SEM)	Clinical score day 4 (Mean ± SEM)	Retreatment (%) (yes/no)	Chronic cases (%)	Mortality caused by BRD (%)
GH	7.89 ± 1.30	3.15 ± 2.73a	75.4&	0.0a	12.3
GNH	7.95 ± 1.59	4.69 ± 2.39b	87.7&	9.2b	16.9

Different letters between groups indicate significant differences between them (p < 0.05). A statistical tendency between groups is represented with “&.” GH: Experimental group composed by clinically sick calves of BRD, treated with florfenicol + meloxicam, and orally hydrated for five days in a volume corresponding to 7% of the BW. GNH: Experimental group composed of clinically sick calves of BRD and treated with florfenicol + meloxicam.
