Effects Of Female Sex Hormones And Dietary Magnesium Levels In Sheep, Kenny S. Marbury

Masters Theses

The major objectives of this study were to evaluate (a) the effects of diet on magnesium, calcium and potassium metabolism in yearling wethers and (b) the effects of progesterone, estradiol and diethylstilbestrol (DES) on the metabolism of the minerals.

A two by two factorial design was selected whereby twelve yearling crossbred wether lambs were divided into four groups of three.

Comparison Of Wild And Hatchery Brook Trout In Spruce Flats Branch, Great Smoky Mountains National Park, W. Douglas Harned

Reasons for the disappearance of the only salmonoid native to the southern Appalachians appears to be a combination of factors. Among them, improper logging practices and the widespread introduction of the rainbow and brown trout are probably the most detrimental. The purpose of this study was to evaluate …

Masters Theses

An experiment was conducted to evaluate the effectiveness of a douche with an antibiotic formula to improve reproductive efficiency in dairy cows.

A total of 102 cows was utilized in the experiment. The 81 Holstein cows were divided into four groups. These groups were untreated cows which had normal post-calving recuperation (N-C), treated cows with had normal post-calving recuperation (N-T), untreated cows which had experienced post-calving complications (M-C), and treated cows which had experienced post-calving complications (M-T).
