1.1 This practice describes a procedure for determining the subacute dietary toxicity of a test substance administered to birds in their daily diet. The LC50 value time to mortality and slope of the dose response curve may also be derived.

1.2 This practice is applicable to substances that can be mixed uniformly into the diet.

1.3 This practice is intended primarily to be used with the young of the following species: northern bobwhite ( Colinus virginianus ), Japanese quail ( Coturnix japonica ), mallard ( Anas platyrhynchos ), and ring-necked pheasant ( Phasianus colchicus ). Other species or age groups, for example, with wild-trapped birds, may be used with appropriate husbandry modifications to the practice.
