Effect Of Feed Additives And Toxic Elements On Swine Growth Performance, Nutrient Digestibility, Immune Function And Reproductive Performance, Richard A. Mudarra Hernández

Graduate Theses and Dissertations

To evaluate the effects of peptide in combination of zinc oxide (Zno) or acidifiers (Exp 1), and gossypol (G) from cottonseed meal (CSM) ( Exp 2&3) on growth performance, complete blood cell counts (Exp 1, 2&3), nutrient digestibility (Exp 1), plasma gossypol (Exp 2&3) and semen quality (Exp 3), weaned pigs (Exp 1), growing gilts (Exp 2) and growing boars (Exp 3) were randomly allotted to dietary treatments. Treatments for Exp 1 during phase 1&2 were: (1) Positive Control (PC), formulated to meet NRC (2012) nutrient requirements; (2) Negative control (NC), fish meal was reduced to achieve -0.13% SID lysine; …

Effects Of Crystalline Amino Acid Supplementation Of Reduced Crude Protein (Rcp) Diet On Net Energy Basis On Growing-Finishing Swine, Daniel Cook

Graduate Theses and Dissertations

Barrows and gilts (n=210) were used to test the effects of crystalline amino acid (AA) supplementation of reduced crude protein (RCP) diets formulated on a net energy basis on quality characteristics of the LM from growing-finishing pigs. Pigs were blocked by weight, and pens (3 barrows and 3 gilts/pen) within each block were assigned randomly to either corn-soybean meal diets (C) or 1 of 3 RCP diets and added crystalline AA levels for the dietary treatments during each feeding phase. During the last 3-wk feeding phase, 10 ppm of ractopamine were included in all diets. At slaughter and after a …

Visual And Linguistic Influences On Public Perceptions Of Swine Confinement, Arthur Leal

Graduate Theses and Dissertations

This study was designed to analyze the visual and linguistic characteristics of online (YouTube) videos and electronic newspapers, identifying relationships with positive, negative, and neutral attitudes toward swine confinement.

This study followed a content analysis design. Two coders, trained to an acceptable level of agreement (κ = .68), examined online videos and electronic newspapers, assessing linguistic and visual images used in relation to attitudes toward swine confinement. A series of search terms deemed suitable for this study's objectives were employed in multiple search engines, and 48 articles and 157 videos were coded for content.

Results from this study showed that …
