The Effect Of Dam Parity On Progeny Growth Performance, Passive Immunity, And Gastrointestinal Microbiota, Erin E. Hinkle
The Effect Of Dam Parity On Progeny Growth Performance, Passive Immunity, And Gastrointestinal Microbiota, Erin E. Hinkle
Department of Animal Science: Dissertations, Theses, and Student Research
Previous research has shown that parity (P) 4 progeny have greater weaning weights and decreased microbial diversity compared to P1 progeny. Three experiments were conducted to evaluate litter performance, passive immunity, and fecal microbiota among P1 and P3 dams and their progeny. In experiment 1, 56 P1 and 49 P3 dams and their progeny’s litter and growth performance, immunoglobulin (IgG and IgA) concentrations, and gut microbiota were evaluated. In experiment 2, 48 pigs per P were selected to determine growth performance, immunoglobulin (IgG and IgA) concentrations, and gut microbiota. In experiment 3, 8 dams per P were selected. At birth, …

Porcine reproductive and respiratory syndrome (PRRS) causes decreased reproductive performance in breeding animals and increased respiratory problems in growing animals, which result in significant economic losses in the swine industry. Vaccination has generally not been effective in the prevention of PRRS, partially because of the rapid mutation rate and evolution of the virus. The objective of the current study was to discover the genetic basis of host resistance or susceptibility to the PRRS virus through a genome-wide association study using data from the PRRS Host Genetics Consortium PRRS-CAP project.
Three groups of approximately 190 commercial crossbred pigs from 1 breeding …

The objective of the research was to determine the optimum application rates of soybean peroxidase (SBP) plus peroxide (SBPP) for reducing odorous VOC emissions from swine manure. Industrial-grade SBP was applied in combination with liquid hydrogen peroxide (H2O2) or powdered calcium peroxide (CaO2) to standard phenolic solutions and swine manure, and emissions were measured in a wind tunnel. The primary odorant in the untreated manure was 4-methylphenol, which accounted for 68–81% of the odor activity value. At the optimum application rate of SBPP (50 g L-1), 4-methylphenol emissions were reduced from the …

Feral swine populations are expanding throughout the U.S., where they are causing increasing amounts of damage to agriculture, natural resources, and property and threaten human health and safety. Methods to control feral swine damage in the U.S. consist of integrated fencing, trapping, snaring, and shooting (including hunting with dogs) efforts. New methods that are being developed to control feral swine damage include toxicants and fertility control agents. For these emerging technologies to be effective at the population level, they must function through oral routes of delivery. Concurrent to the development of orallydelivered actives, a cost-effective system that delivers biologics to …

The main objectives of this study were to determine the prevalence and antimicrobial resistance patterns of Escherichia coli isolates in feces of pigs and their production environments on farms. A total of 560 isolates of Escherichia coli, from 112 samples obtained from weaner and finisher pigs, feed, water, and house sparrows on 8 farrow-to-finish farms, were tested for susceptibility to 16 antimicrobials. The prevalence of resistance varied widely (0.0% to 69.5%) among the antimicrobials tested. From the tested swines, 75.75% of the isolates were resistant to one or more antimicrobials. Resistance was significantly more frequent (P = 0.005, P < 0.01) in swine isolates compared to those from feed, water, and sparrows and significantly more frequent (P = 0.007, P < 0.01) in weaner pigs compared to finisher pigs. The findings indicate that resistance to a broad range of antimicrobials was prevalent among fecal E. coli isolates of swine on the study farms. Fortunately, E. coli was not isolated from the feed, water, and house sparrows.
