Effect of 0.2% Dietary Chitosan on Incidence and Levels (Colony-Forming Units/g) of Salmonella Typhimurium Recovery at 7 Days of Age in Broiler Chickens
| Trial 1 | Trial 2 | |||
|---|---|---|---|---|
| Treatment | Cecal tonsils | Log10 ST/g of ceca content | Cecal tonsils | Log10 ST/g of ceca content |
| Control | 15/20 (75%) | 4.20±0.82a | 15/20 (75%) | 5.00±0.62a |
| Chitosan 0.2% | 9/20 (45%) | 2.28±0.75b | 12/20 (60%) | 3.34±0.72b |
Cecal tonsils data are expressed as positive/total chickens for each tissue sampled (%).
Log10 S. Typhimurium/g of ceca content data are expressed as mean±standard error.
Values within a column with no common superscript differ significantly (p<0.05).
