Effect Of Swine Manure Pit Additives And Facility Disinfectants On The Fate Of Antibiotics And Manure Composition During Simulated Swine Manure Slurry Storage, Jon Duerschner
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
This thesis investigates the effect of time and of swine manure slurry treatment on the physical properties, nutrient content, and the concentrations of antibiotics chlortetracycline, lincomycin, and tiamulin in simulated storage of swine manure. In one experiment the slurry was treated with six additive products. In a second experiment a set of four disinfectant products were used. Control consisted of unamended slurry. Manure was stored in 60 liter stainless steel bioreactors to simulate deep pit storage and was sampled 7 times over a 40 day incubation.
From an ANOVA of the results, it was concluded that evaporation may be contributing …
