Table 3.

Effects of treatments on necrotic enteritis lesion scores (d 22) and mortality (d 16–22) in broiler chickens.

Treatments	Lesion score			Mortality² (%)
Treatments	Duodenum	Jejunum	Ileum	Mortality² (%)
NC¹	0.000^c	0.000^c	0.000^c	0.000^c
PC	0.187^a	1.131^a	0.944^a	8.17^a
AMP	0.093^b	0.769^b	0.621^b	2.53^bc
Antibiotic	0.148^ab	0.955^ab	0.783^ab	3.44^b
SEM³	0.119	0.285	0.373	0.819
P-value	0.034	0.001	0.013	0.001

^a–cValues within a column with different letters differ significantly (P < 0.05).

¹NC: negative control group received corn-soybean meal diet without challenge and additives; PC: positive control group received NC diet experimentally challenged with necrotic enteritis; AMP: PC received group supplemented with 20 mg antimicrobial peptide/ kg diet; Antibiotic: PC received group supplemented with 45 mg antibiotic (bacitracin methylene disalicylate)/kg diet.

²Only mortalities shown necrotic enteritis signs.

³SEM: standard error of means (results are given as means (n = 12) for each treatment).
