Abstract
The Packed cell volume (PCV) values of broiler chickens were determined before and after experimental challenge with a virulent field strain of Salmonella enterica subspecies Gallinarum. The chickens were vaccinated with the NVRI Vom FT vaccine at recommended dose at 5 weeks of age. 10 days later when all chickens had seroconverted, each of the chickens were then challenged with 1ml inoculum containing approximately 3.0x108 colony forming units (CFU) of a virulent field strain of Salmonella enterica subspecies Gallinarum. PCV of individual chickens were determined before and 7 days after challenge. These 2 PCV values were then analyzed statistically using the related sample t test. The results showed values of t obtained of 2.08 as compared to t critical of 2.20. The values obtained showed that the difference in values of PCV of the vaccinated broilers before and after challenge was not statistically significant. A third blood sample obtained 7 days after the second blood sample showed slight increase in PCV from birds sampled.

Key words: Packed Cell Volume, Fowl typhoid, Whole Blood Agglutination Test, Broiler chickens.
