Nutritional influences affecting senecio toxicity in laboratory animals

Creator:: Buckmaster, Gary Wayne
Abstract:: The objective of this research project was to evaluate the toxicity of local pyrrolizidine alkaloid containing plants and to examine the influence of dietary protein, with particular reference to the amino acid cysteine, upon this toxicity. Senecio vulgaris (common groundsel) was shown to be more toxic than Senecio jacobaea (tansy...

The relationship of estradiol to embryo-maternal interactions in the llama

Creator:: Powell, Susan A.
Abstract:: In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...

The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

Creator:: McNeel, Anthony Kent
Abstract:: Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

Effects of Feeding OmniGen-AF® on Superovulatory Response in Donor Beef Cows

Creator:: Snider, Alexandria P.
Abstract:: One assisted reproductive tool used to propagate highly desirable genetics from elite sire and dam matings is embryo transfer. Superovulation is the first part of the overall protocol and it is a required yet costly and biologically stressful procedure in cattle embryo transfer. The process of superovulation results in high...

Mutagenic and toxicologic implications of pyrrolizidine (Senecio) alkaloids

Creator:: White, Randy Dee
Abstract:: The Salmonella/mammalian-microsome mutagenicity test was used to evaluate Senecio jacobaea (SJ) plant, Pyrrolizidine alkaloids (PA) and metabolites in goat milk, to evaluate response differences with microsomes from several animal species and to compare SJ plant responses to other plants. Bioassessment experiments were conducted to evaluate PA toxicity changes associated with...

Evaluation of wet brewers' grain ensiled with low quality forages

Creator:: Kennedy, Matthew A. (Matthew August)
Abstract:: Two experiments were conducted to evaluate the use of wet brewers' grain (WBG) alone and with straw so it can be used as part of the sole ration for ruminants. In Exp. 1, WBG was ensued alone and was mixed with one of two straws, wheat or tall fescue grass...

Comparative aspects of copper metabolism as reflected by the composition of animal tissues

Creator:: Idris, Omer Fadle
Abstract:: An extensive review of the literature dealing with the role of copper in nutrition has been made; much emphasis has particularly been placed upon some of the "comparative" aspects of copper metabolism in various species. A study of the comparative copper metabolism of three strains of rats and of golden...
