Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards Comparison of the effects of seleno-Lmethionine, seleno-DL-methionine, and selenized yeast on reproduction of mallards

The toxicities of seleno-l-methionine, seleno-dl-methionine, and selenized yeast were compared. Ten pairs of mallards were fed a control diet and 15 pairs were fed diets containing 10 ppm selenium as seleno-dl-methionine, seleno-l-methionine, or selenized yeast. Hatching of fertile eggs was significantly lower for females fed 10 ppm selenium as seleno-dl-methionine (7.6%) and seleno-l...

Malocclusion in the jaws of captive bred Arctic wolves Malocclusion in the jaws of captive bred Arctic wolves

Similar abnormalities in the skulls of captive Arctic Wolves (Canis lupus arctos) and a wild Arctic wolf found dead on Ellesmere Island, Canada, in 1986 are described. The malocclusion is likely to be recessively inherited and would be expressed more frequently in association with increased levels of inbreeding. A re-shaping of the skulls may have occurred due to the effects of the...
