TABLE 2.

Performance parameters, clinical scores and mortality rate of different groups.

Groups	Body weight (g)		FCR	Clinical signs score				Mortality
	Day 25	Day 37		Days post‐challenge
	Day 25	Day 37		3rd	6th	9th	12th
NC	1100 ± 45^a	2240 ± 111^a	1.98	1 ± 0^a	1 ± 0^a	1 ± 0^a	1 ± 0^a	0/15^a
PC	1094 ± 34^a	2111 ± 118^a	2.18	2.7 ± 0.67^b	3.2 ± 0.42^b	2.8 ± 0.79^b	2 ± 0.67^a	3/15^b
AB	1100 ± 45^a	2181 ± 115^a	2.15	2.7 ± 0.67^b	3.2 ± 0.42^b	2.8 ± 0.79^b	2.1 ± 0.74^a	2/15^b

Note: Data for parameters other than FCR and mortality rate are presented as mean ± SD. Different superscript letters show significant difference in a column (p < 0.05). NC: negative control (no treatment); PC: (positive control) birds that challenged with H9N2 and infectious bronchitis viruses; AB: challenged birds that received enrofloxacin in drinking water after appearance of symptoms for 5 consecutive days.
