The Effects Of Actigen® And Threonine Supplementation On Growth Parameters, Immune Function, And Intestinal Health In Monogastrics, Lindsay Good
Theses and Dissertations--Animal and Food Sciences
The objectives of these experiments were to evaluate the main effects and interactive effects between dietary supplementation of a mannan oligosaccharide based product, Actigen® (ACT), and different levels of threonine in monogastrics, as evidenced by growth parameters, immune function, and intestinal health characteristics.
In nursery piglets, ACT supplementation decreased average daily feed intake (P=0.04), but had no effect on body weight or feed conversion ratio. There were no noted differences between threonine levels on performance traits. There were no consistent differences in complete blood count or cytokine gene expression profiles in the blood. The highest level of threonine, …
Effects Of A Proprietary Premix On Productive Performance And Egg Quality Of White And Brown Egg Laying Hens Fed Diets High In Distillers Dried Grains With Solubles (Ddgs), Megan D. Van Benschoten
Effects Of A Proprietary Premix On Productive Performance And Egg Quality Of White And Brown Egg Laying Hens Fed Diets High In Distillers Dried Grains With Solubles (Ddgs), Megan D. Van Benschoten
Theses and Dissertations--Animal and Food Sciences
The objective of this thesis was to evaluate inclusion of up to 35% by-product DDGS (with reduced Ca and P) with and without addition of a proprietary premix (enzyme and antioxidant; Alltech Inc.) on productive performance and egg quality of white and brown egg laying hens. A total of 288 white or brown hens were randomly allocated to one of the following treatments: 1) corn-soybean meal (control), 2) 25% DDGS, 3) 25% DDGS plus premix, 4) 35% DDGS, and 5) 35% DDGS plus premix. Hen body weight values were impaired with addition of 25 and 35% DDGS when compared to …
Dietary Antioxidant Supplementation (Economase–Bioplex) To Alleviate Adverse Impacts Of Oxidized Oil On Broiler Meat Quality: A Chemical, Textural, Enzymatic, And Proteomic Study, Rebecca Delles
Theses and Dissertations--Animal and Food Sciences
This study investigated the influence of dietary antioxidants and quality of oil on the oxidative and enzymatic properties of chicken broiler meat stored in an oxygen-enriched package (HiOx: 80% O2/20% CO2) in comparison with air-permeable polyvinylchloride (PVC) or skin (SK) packaging systems during retail display 2–4 °C for up to 14, 7, and 21 d, respectively. Broilers were fed a diet either with a low-oxidized oil (peroxide vale POV 23 meq O2/kg) or with a high-oxidized oil (POV 121 meq O2/kg), supplemented with an antioxidant pack (200 ppm EconomasE and organic minerals …
