Effects of avilamycin in swine and poultry wastes on methane production in anaerobic digesters
AbstractBroilers in finishing batteries and barrows in individual metabolism crates were used to produce manure for an anaerobic digester study to determine if avilamycin in the diet affected anaerobic digestion of the manure. A corn-soy based diet, with 80 mg/kg avilamycin, was compared to the control diet fed to swine and a corn-soy based diet, with 20 mg/kg avilamycin, was compared to the control diet fed to poultry. Manure loading rates tested ranged from 3·5 to 52·5 kg VS/m3 for poultry manure and 3·0 to 45·0kg VS/m3 for swine manure during 5-day batch digester trials. Manure loading rates for the large seed digesters were 3–4 kg VS/m3 at a 15-day retention time. Based on four batch digester trials and the monitoring of 20-liter mesophilic digesters for a 19-week period, the presence of avilamycin in swine diets (80 mg/kg) and in poultry diets (20 mg/kg) did not have any adverse effect on total gas production, methane production, valatile solids (VS) reduction and gas production efficiency of anaerobic digesters. Using typical VS loading rates (3–4 kg VS/m3) for mesophilic anaerobic digesters with manure from swine or broilers fed recommended levels of avilamycin should allow for efficient digester operation.
