SELENIUM COMPOUNDS, SELENOMETHIONINE TOX-REPRO - physiology egg fertility, egg weight, eggshell thickness, and mean interval between laying of eggs versus controls no effect 15 pairs/treatment group, 10 pairs/control group Adult through reproduction until 6 days of age in ducklings Toxicity Factor Datasets
SELENIUM COMPOUNDS, SELENOMETHIONINE TOX-REPRO - reproductive success hatchability versus controls reduced with seleno-L-methionine or seleno-D,L-methionine 15 pairs/treatment group, 10 pairs/control group Both Adults and Juveniles through reproduction until 6 days of age in ducklings Toxicity Factor Datasets
SELENIUM COMPOUNDS, SELENOMETHIONINE TOX-REPRO - reproductive success duckling survival compared to controls reduced with seleno-L-methionine 15 pairs/treatment group, 10 pairs/control group Adult through reproduction until 6 days of age in ducklings Toxicity Factor Datasets
SELENIUM COMPOUNDS, SELENOMETHIONINE TOX-REPRO - reproductive success number of 6-day-old ducklings produced per female versus controls reduced with seleno-D,L-methionine, seleno-L-methionine, or selenized yeast 15 pairs/treatment group, 10 pairs/control group Both Adults and Juveniles through reproduction until 6 days of age in ducklings Toxicity Factor Datasets
