                                Technical Abstract: Previous reports have observed that chlorate compounds reduce E. coli and Salmonella infections in swine, broilers, and market-age turkeys.  The following studies were performed to investigate the effects of an experimental chlorate product (ECP) on Salmonella typhimurium (ST) infections of day-of-hatch turkey poults.  In all trials, day of hatch turkey poults were challenged with ST and administered ECP in the drinking water for 4 days.  After the treatment period, treatments were replaced with water for an additional 5 days.  On the 10th day, ceca were collected and cultured for ST.   In trial 1, day-of hatch turkey poults were challenged with 1 X 10**6 cfu of ST and administered either 0, 1X, 2X, 3X, or 4X of the ECP (a 1X concentration is equivalent to a 7.5 mM chlorate ion concentration).  For all treatment concentrations in trial 1, turkeys provided ECP had significantly (P<0.05) lower populations (> 1.2 log reduction) and incidences of ceca ST as compared to control birds (2.1 log ST).  Trial 2 was performed similar to trial 1 with the exception that poults were challenged with 2 X 10**5 cfu of ST.  In trial 2, 1X and 4X concentrations of the ECP had significantly (P<0.05) lower populations   (> 1.4 log reduction) and incidences of ceca ST as compared to control birds (1.8 log ST).  These experiments suggest that the experimental chlorate compound significantly reduces Salmonella colonization in day-of-hatch commercial turkeys poults.
