Estrogen regulation of pituitary function in the gonadectomized sheep

Creator:: Cooper, Gordon Jay
Abstract:: A total of five individual experiments were conducted with gonadectomized, male sheep to study the influence of estrogen on the plasma level of pituitary activities, with the greatest emphasis given to gonadotropic activity. Estrogen treatments employed were as follows: 1. 12 mg. diethylstilbestrol (DES) implanted subcutaneously. 2. 1 mg. DES...

Selenium effects and species differences in hepatic metabolism of pyrrolizidine alkaloids and other xenobiotics

Creator:: Shull, Lee R.
Abstract:: The metabolism of pyrrolizidine alkaloids and other drugs was studied with regard to nutritional status and species differences. Pyrrolizidine alkaloids which are biotransformed to severely toxic metabolites were isolated from tansy ragwort (Senecio jacobaea). Semi-purified alkaloid crystals containing five alkaloids (senecionine, seneciophylline, jacobine, jacoline, and jacozine) were prepared and found...

Evaluation of tropical forages and by-product feeds for rabbit production

Creator:: Raharjo, Yono C.
Abstract:: An evaluation was made on the nutritive value of tropical forages and by-product feeds for rabbit production. Digestibility of nutrient fractions, feed preferences, growth, combination of forages, supplementation of micro and macro nutrients and/or effects of drying temperature on the quality of four groups of forages, namely woody legumes (WL),...

Evaluation of bamboo as livestock forage and applications of Yucca schidigera and Quillaja saponaria products in agriculture

Creator:: Greenway, Stephanie L.
Abstract:: Byproducts of bamboo processing, such as leaves and branches, may have potential as a livestock feedstuff. The objectives of this study were to evaluate seasonal changes in proximate composition of several bamboo species and reed canarygrass, and subsequently determine the digestibility of bamboo in ponies. Monthly samples of Phyllostachys bissetii,...

The effects of ryegrass straw and monensin on performance of feedlot lambs

Creator:: Shqueir, Adnan Ali
Abstract:: The objectives of this study were to investigate the effects of the by-product, ryegrass straw, and the feed additive, monensin, on the performance of feedlot lambs. Four pelleted rations were fed ad libitum: Ration 1 - 50% barley, 50% alfalfa hay; Ration 2 - 50% barley, 50% alfalfa hay and...

Gastrointestinal Parasitism and Mercury in Pacific Walrus

Creator:: Sweitzer, Danielle N.
Abstract:: The Pacific Walrus population that lives within the Chukchi Sea near Alaska and the Russian territory Siberia have traditionally held a diet composed of molluscs and benthic invertebrates, with the main dietary choice being clams or other bivalves. Due to global warming, the availability of stable ice resting surfaces has...

Proximate Factors Influencing Cat Behavior, Cognition, and The Human-Cat Bond

Creator:: Vitale, Kristyn R.
Abstract:: The domestic cat is one of the world’s most popular companion animals. However, to date much remains to be learned about cat behavior and the cat-human relationship. To examine the influence of proximate factors on cat behavior and the human-cat bond, three studies were undertaken. Study 1 directly measured the...

Expression of extracellular matrix proteins during blastulation in bovine embryos and factors affecting bovine endodermal cell outgrowth In Vitro

Creator:: CoreyAyne, Singleton
Abstract:: During early embryonic development, endodermal cells leave the inner cell mass (ICM) and migrate over an extracellular matrix (ECM), located on the blastocoelic side of the trophectoderm, to form a continuous layer of extraembryonic endoderm. Cell migration events depend on a family of cell surface proteins known as integrins that...

Senecio jacobaea : toxicity and effects on mineral metabolism in animals

Creator:: Swick, Robert Alphonso
Abstract:: Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...
