A complete random design experiment was conducted to determine the effect of dietary arsonic acids on swine waste composition and decomposition in anaerobic pits. Vitamin and mineral fortified corn-soybean meal basal diets with either 75 ppm roxarsone or 100 ppm arsanilic acid were fed to growing-finishing pigs (14 to 91 kg) with daily fresh waste collection and addition to model anaerobic pits.Arsonic acids in the diet influenced (P<.001) pH, dry matter, volatile solids, Kjeldahl nitrogen, ammonium nitrogen and arsenic content in the model anaerobic pits. Compared to the control there was a significant decrease in dry matter and volatile solids. Arsanilic acid in the diet increased (P<.001) the amount of nitrogen in the ammonium form compared to the control and roxarsone diet. Arsanilic acid increased (P<.05) the acetic acid content in the anaerobic pit compared to the control when expressed as a percentage of total volatile fatty acids measured.Elemental arsenic losses to the atmosphere were measured in anaerobically stored waste from all treatments. |
