Current swine industry practice is to house animals in confinement facilities which capture and store feces and urine as slurry in pits below the production area. Additives and disinfectants may be introduced into the manure pits. This study was conducted to measure the effects of additives and disinfectants on temporal changes in swine slurry characteristics. Slurry from a commercial swine production facility in southeast Nebraska, USA was collected and transferred to 57 L reactors located within a greenhouse. Selected additives and disinfectants were added to the reactors and physical properties, chemical characteristics, and antibiotic concentrations were monitored for 40 days. Concentrations of dry matter (DM), total nitrogen (TN), phosphorus pentoxide (P₂O₅), calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), manganese (Mn), and copper (Cu) were significantly greater than the Control in each of the reactors containing additives. The reactors in which the additives MOC-7, More Than Manure®, Sludge Away, and Sulfi-Doxx were introduced had significantly greater values of chemical oxygen demand (COD), total volatile solids (TVS), total suspended solids (TSS), total solids (TS), dry matter (DM), TN, P₂O₅, Ca, Mg, Zn, Fe, Mn, Cu and chlortetracycline than the other additive treatments. Concentrations of TVS and TSS were significantly lower in the reactors containing Clorox® and Virkon™ than the other disinfectant treatments. The total dissolved solids (TDS) concentration of 26,500 mg L⁻¹ and pH value of 7.27 obtained for the reactors containing Tek-Trol were significantly greater than measurements obtained for the other treatments. Concentrations of chlortetracycline and tiamulin of 8840 and 28.8 ng g⁻¹, respectively, were significantly lower for the treatments containing Tek-Trol. The sodium (Na) concentration of 1070 mg L⁻¹ measured in the reactors containing Clorox® was significantly greater than values for the other disinfectant treatments. The introduction of selected additives and disinfectants may influence certain physical properties, chemical characteristics, and antibiotic concentrations of swine slurry.

当前养猪业的做法是将动物饲养在封闭设施中，该设施以粪便和尿液的形式捕获并存储在生产区域下方的矿坑中。可以将添加剂和消毒剂引入粪坑。进行这项研究以测量添加剂和消毒剂对猪粪浆特性随时间变化的影响。收集了来自美国内布拉斯加州东南部商业猪生产设施的浆液，并将其转移到位于温室内的57升反应器中。将选定的添加剂和消毒剂添加到反应器中，并在40天之内监测其物理性质，化学特性和抗生素浓度。干物质（DM），总氮（TN），五氧化二磷（P ₂ O ₅）的浓度），钙（Ca），镁（Mg），锌（Zn），铁（Fe），锰（Mn）和铜（Cu）在含有添加剂的每个反应器中均显着大于对照。引入了添加剂MOC-7，More ThanManure®，Sludge Away和Sulfi-Doxx的反应器的化学需氧量（COD），总挥发性固体（TVS），总悬浮固体（TSS），总固体（TS），干物质（DM），TN，P ₂ O ₅，Ca，Mg，Zn，Fe，Mn，Cu和金霉素比其他添加剂处理要好。在含有Clorox®和Virkon™的反应器中，TVS和TSS的浓度明显低于其他消毒剂处理。总溶解固体（TDS）浓度为26,500 mg L ^-1含有Tek-Trol的反应器获得的pH值为7.27，明显高于其他处理获得的测量值。对于含有Tek-Trol的治疗，金霉素和噻菌灵的浓度分别为8840和28.8 ng g ^-1明显较低。在含有Clorox®的反应器中测得的钠（Na）浓度为1070 mg L ^-1，大大高于其他消毒剂处理的值。所选添加剂和消毒剂的引入可能会影响猪粪的某些物理特性，化学特性和抗生素浓度。
