Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan A. Lichtenwalter, Jason K. Apple, Beth Kegley, Tsung C. Tsai
Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan A. Lichtenwalter, Jason K. Apple, Beth Kegley, Tsung C. Tsai
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Overall, no effect of teat order was found on average daily gain, average daily feed intake, gain-to-feed ratio, or body weight among pigs from each section …
Life Cycle Assessment Of Alternative Swine Management Practices, Prathamesh Avadhut Bandekar
Life Cycle Assessment Of Alternative Swine Management Practices, Prathamesh Avadhut Bandekar
Graduate Theses and Dissertations
Life Cycle Assessments (LCAs) are quantitative analyses of complex systems for evaluation of impacts and risk associated with management decisions. LCAs can be effective tools for determining comparative advantages of management strategies across specific impact concern. In this study, life cycle assessments of pork production management alternatives was performed. The alternative management practices included in this study were production of entire males (boars), use of pens for gestation housing, immunocastration, production without growth promoting antimicrobials, production without growth promoting and preventive antimicrobials, and production without ractopamine. These LCAs evaluated the impact of each management strategy on greenhouse gas emission (GHG), …
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 …
