The effects of 6 different litter amendments on broiler performance, level of atmospheric ammonia (NH3) concentration, and soluble reactive phosphorus (SRP) in litter was determined. Through 3 experiments conducted on 2 different commercial farms, one chemical amendment was added to the litter and then was compared with a control. Broiler performance was not affected by any of the amendments except the ferrous sulfate amendment for which mortality was 25.5%. Application of aluminum chloride (AlCl3 x 6H2O) to the litter lowered atmospheric ammonia concentrations at 42 d by 97.2%, whereas ferrous sulfate (FeSO4 x 7H2O) lowered it by 90.77%. Ammonia concentrations were reduced by 86.18, 78.66, 75.52, and 69.00% by aluminum sulfate [alum or Al2(SO4)3 x 14H2O)], alum + CaCO3, aluminum chloride + CaCO3, and potassium permanganate (KMnO4), respectively, when compared with each control at 42 d. Each amendment except KMnO4 significantly reduced SRP contents. Alum and aluminum chloride were the effective compounds evaluated on the commercial farms with respect to reducing ammonia contents, phosphorus solubility, and mortality.
测定了6种不同垫料改良剂对肉鸡生产性能、舍内氨气（NH₃）浓度水平以及垫料中可溶性活性磷（SRP）的影响。通过在2个不同商业养殖场进行的3项试验，向垫料中添加一种化学改良剂，然后与对照组进行比较。除硫酸亚铁改良剂导致死亡率为25.5%外，其他改良剂均未对肉鸡生产性能产生影响。向垫料中施用六水合氯化铝（AlCl₃·6H₂O）可使42日龄时舍内氨气浓度降低97.2%，而硫酸亚铁（FeSO₄·7H₂O）可使其降低90.77%。与各对照组在42日龄时相比，硫酸铝[明矾或Al₂(SO₄)₃·14H₂O]、明矾 + CaCO₃、氯化铝 + CaCO₃和高锰酸钾（KMnO₄）分别使氨气浓度降低了86.18%、78.66%、75.52%和69.00%。除KMnO₄外，每种改良剂均显著降低了SRP含量。就降低氨气含量、磷溶解度和死亡率而言，明矾和氯化铝是在商业养殖场评估的有效化合物。
