Theses and Dissertations--Animal and Food Sciences
Consumption of endophyte-infected tall fescue by cattle has repeatedly been shown to negatively impact dry matter intake (DMI), growth rate, and circulating prolactin concentrations. The objective of the current study was to determine if a mineral supplementation would mitigate the negative effects of fescue-derived alkaloid consumption on feed intake, circulating prolactin, and the vascular system. Twelve Angus crossbred steers were used in a triplicated Latin square design consisting of three 28 d experimental periods. Treatments consisted of three top-dressed mineral supplements (142 g/head/d): a non-medicated control (CON), commercially available Fescue EMT® Mineral Defense (EMT), and a test prototype (EMT 2). …
