Datapoints

Displaying 1 - 6 of 6 datapoints.
Species: Mallard duck (Anas platyrhynchos)
Chemical Toxicity Endpoint Type Endpoint Description Endpoint Value Sample Size Life Cycle Stage Study Duration Type
SELENOMETHIONINE TOX-MORT - dose-response data % survival versus controls no effect 15/group Juvenile 4 weeks Toxicity Factor Datasets
SELENOMETHIONINE TOX-EXP IND - accumulation geometric mean Se concentration in liver (adequate protein in diet) 11.6 (@15 ppm diet), 48.6 (@ 60 ppm diet) ppm, wet wt 15/group Juvenile 4 weeks Toxicity Factor Datasets
SELENOMETHIONINE TOX-Non-Repro-Sublethal - organ/system effects incidence of histopathological changes in livers versus controls increased @ 15 ppm, 60 ppm (adequate protein, no methionine added) 15/group Juvenile 4 weeks Toxicity Factor Datasets
SELENOMETHIONINE TOX-Non-Repro-Sublethal - whole animal body, liver and spleen weights, and tarsus length versus controls decreased @ 60 ppm (regardless of methionine suppl. or protein levels) 15/group Juvenile 4 weeks Toxicity Factor Datasets
SELENOMETHIONINE TOX-Non-Repro-Sublethal - cellular/biochemical effects plasma GSH-peroxidase and alkaline phosphatase activities versus controls increased @ 15 (GSH-peroxidase only), 60 ppm Se, adequate protein 15/group Juvenile 4 weeks Toxicity Factor Datasets
