aLeast square means within each column without a common letter with the control treatment are significantly different (P < 0.05).
1Values represent the least square means of the entire observation period. Treatments: SE-OMP (treatment SE-FA or SE-IM) or ST-OMP (treatment ST-FA or ST-IM), or a combined antigen preparation: ½ SE-OMP and ½ ST-OMP (treatment SEST-FA or SEST-IM). SE = Salmonella Enteritidis; ST = Salmonella Typhimurium; OMP = outer membrane protein. FA = Freund’s adjuvant: Freund complete adjuvant for the first immunization and Freund incomplete adjuvant for the booster immunizations). IM = immunostimulating complexes matrix.
