Metabolism of toxic plant alkaloids in livestock : comparative studies on the hepatic metabolism of pyrrolizidine alkaloids in sheep and cattle and of ergot alkaloids in an endophyte-resistant mouse model

Creator:

Duringer, Jennifer Marie

Abstract:

The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...

The ability of a yeast-derived cell wall preparation to minimize toxic effects of high-alkaloid tall fescue straw in beef cattle

Creator:

Merrill, Melissa L.

Abstract:

Two experiments were conducted to evaluate the influence of a yeast-derived cell wall preparation (YCW) on forage intake and digestibility, ruminal fermentation characteristics, serum prolactin and prolactin stores, and milk production in beef cattle consuming high-alkaloid tall fescue straw. In Exp. 1, 16 Angus x Hereford ruminally cannulated steers (200...
