An adequatenumber of extra animalswill be purchasedso that no animal in obviouslypoor healthis placedon test. (9)Justificationfor SpeciesSelection Historically,rats have been used as representativoef a rodent speciesand are preferredby variousregulatory agencies. B. Dose Administration (1)Dose Level A single dose of 5,000 mg/kg of body weightwill be administeredto-fivemales and five females. Ifno test material-relatemdortalityis producedat thislevel,no 24 CHW 61101149 TP2069 Page 6 furthertestingwill be required.If anymortalityoccurs at the 5,000mg/kg dose level,additionaldos levelsmay be added at the directionof the studydirect:rin order to meet the objectivesof the study. (2)Dose Preparationand Administration All animalswill receivethe sameconcentratioonf test mixtureper dose level. If a solid,the testmaterial will be suspendedin an appropriatevehicle. If a liquid, the testmaterialwill be dosed undiluted,usingthe bulk densityto determinethe dose volume. If the materialis an aerosol,it will be dischargedinto a beakerand administeredas a liquid. Individualdoseswill be based upon the animal'sbody weight takenjust beforetest materialadministration,and administeredby gavage. The animalswill have food withheldfor 17 to 20 hoursbefore testmaterialadministration.The preparedtestmixtures will be storedat roomtemperatureuntiladministration.
