Effect of dietary spray-dried plasma on the concentration of Salmonella Enteritidis in ceca and liver of broiler chicks (Experiment 1).

	Log₁₀ CFU / g cecal contents		Liver invasion ratio³ (Day 3 PC)
Treatments¹	Day 3 PC²	Day 14 PC
CON-SE	2.16 ± 0.22^a	2.28 ± 0.29^a	6/8^a
BMD-SE	1.24 ± 0.24^b	1.54 ± 0.43^b	1/8^b
SDP-SE	2.28 ± 0.27^a	1.16 ± 0.03^b	4/8^ab
SEM	0.247	0.104	0.161
P-value	0.0131	0.0001	0.0390

^a,bMean values bearing different superscript letters within a column are significantly different (P < 0.05).

Treatment CON consisted of chicks fed unmedicated corn-soybean meal (SBM) basal without SDP; Treatment BMD consisted of chicks given unmedicated corn-SBM basal into which bacitracin methylene disalicylate (BMD) was added at 0.055 g/kg diet; Treatment SDP consisted of chicks given unmedicated corn-SBM basal into which SDP was added at 30g/kg diet; Treatments CON-SE, BMD-SE, and SDP-SE, consisted of chicks that were given diets similar to CON, BMD, and SDP, respectively, and were each inoculated with 7.46 × 10⁸ CFU Salmonella Enteritidis /mL at 1 d of age.

PC, postchallenge.

Liver invasion Ratio = number of birds whose liver(s) were positive for Salmonella Enteritidis / Total number of birds evaluated in each treatment category.
