Evaluation Of Increasing Levels Of Mycotoxin-Containing Corn Fines On Diet Choice And Growth Performance Of Nursery Pigs, Duncan B. Paczosa

Theses and Dissertations--Animal and Food Sciences

Pigs fed mycotoxin contaminated diets at high concentrations will result in a detriment to health and performance. An initial study and a follow-up study were conducted to evaluate the effects of feeding increasing levels of mycotoxin-containing corn fines on growth performance, diet preference of pigs, and two possible mitigants.

The initial study was a 3 x 2 factorial containing three levels of fines (0, 10, and 20%, Diets 1-3, respectively) and either 0 ppm (Diets 1-3) or 40 ppm boron (Diets 4-6; Diets 4-6 were Diets 1-3, respectively, plus boron) as sodium tetraborate decahydrate as a possible mitigant. In this …

Effects Of Biosynthesized Bromoform On Enteric Methane Production, Animal Performance And Tissue Residues In Cattle, Sydney Davis

Theses and Dissertations--Animal and Food Sciences

Greenhouse gas (GHG) emissions have been implicated in global warming and extreme climate change conditions. The Environmental Protection Agency (EPA) has identified agriculture, more specifically cattle production, as a major contributor to global GHG production. When expressed as liters of gas, CO2 is considered the primary GHG produced, however, in terms of global warming potential (GWP), CH4 has 25-times greater potential than that of CO2. Due to the elevated GWP of CH4, we have constructed a series of experiments to investigate the use of a halogenated CH4 analogue derived from kelp (i.e., bromoform) as an inhibitor of enteric CH4 production …
