Surveillance And Evaluation Of Manure Treatment Practices For Mitigation Of The Porcine Epidemic Diarrhea Virus (Pedv) In A Commercial Swine Farm Setting, Erin Boyles Dec 2018

Surveillance And Evaluation Of Manure Treatment Practices For Mitigation Of The Porcine Epidemic Diarrhea Virus (Pedv) In A Commercial Swine Farm Setting, Erin Boyles

Department of Animal Science: Dissertations, Theses, and Student Research

The emergence of the porcine epidemic diarrhea virus (PEDv) in the United States in 2013 resulted in billions of dollars in annual losses for the U.S. swine industry. Infection with PEDv causes severe diarrhea and vomiting in pigs, spreads rapidly through ingestion of infected manure, and produces nearly 100% mortality in pre-weaned piglets. Because swine manure slurry is a valuable crop nutrient source, concerns about virus persistence in stored manure remain a major barrier to proper manure management. Proper manure handling and application practices are necessary to control the risk of pathogen re-infection at affected production sites or infecting new …

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 …
