The potential of a novel oxy-halogen compound (OHC) to alter early growth and nitrogen retention of broiler chickens challenged with Salmonella was evaluated. Three hundred and twenty female broiler chicks (Arbor Acres X Arbor Acres) were weighed and distributed randomly within a 2 X 4 factorial arrangement of treatments. Main effects examined were the presence or absence of Salmonella typhimurium (ST) inoculation and OHC treatment. At hatching, 80 chicks were placed in electrically heated brooder batteries in each of four identical isolation rooms. Chicks designated to receive 100 microL of an oral inoculum containing 10(5) ST cfu at 3 days of age were in two of the rooms, and uninoculated chicks were raised in the other two rooms. Four replicates of 10 chicks each received drinking water containing either 0, .05, .1, or .5% OHC for each level of ST. Chicks administered .05% OHC exhibited enhanced (P less than or equal to .01) growth at 7 and 14 days of age when compared with control values. A significant OHC by ST interaction was observed at 7 (P less than or equal to .0001) and 14 (P less than or equal to .03) days of age. Feed utilization was improved (P less than or equal to .01) by OHC administration (.05 and .1%) from hatching to 7 days of age. The administration of OHC reduced (P less than or equal to .01) nitrogen excretion and enhanced (P less than or equal to .01) nitrogen retention by chicks at Day 7. Cecal ST log10 counts at 7 days of age for chicks given water containing O, .05, or .1% OHC were 4.72, 3.93, and 3.74, respectively. Oral administration of .05 and .1% OHC enhanced the performance of neonatal chickens.
