The purposes of this study were to determine the effect of Poultry Litter Treatment (PLT) on levels of litter moisture, litter nitrogen, atmospheric ammonia, and death due to ascites. Data were collected from chicks raised in containment conditions that resembled commercial settings. The ascites death rate (5.9%) in broiler chicks on PLT-treated litter was significantly (chi 2 = 15.5, df = 1, P = 0.0001) lower than that (31.5%) in broiler chicks raised on untreated litter. Likewise, atmospheric ammonia levels in pens that had been treated with PLT were significantly (P < 0.05) lower than those in pens that received no treatment. Under the conditions of the present study, litter moisture and litter nitrogen levels were not different (P > 0.05) among treatments at any sample interval.
本研究的目的是确定家禽粪便处理（PLT）对垫料湿度、垫料氮含量、大气氨含量以及腹水致死率的影响。数据收集自饲养在类似商业环境的封闭条件下的雏鸡。经PLT处理的垫料上的肉鸡雏鸡腹水死亡率（5.9%）显著低于（卡方 = 15.5，自由度 = 1，P = 0.0001）未处理垫料上的肉鸡雏鸡腹水死亡率（31.5%）。同样，经PLT处理的鸡舍中的大气氨含量显著低于（P < 0.05）未处理鸡舍中的大气氨含量。在本研究条件下 在任何采样间隔，各处理间的垫料湿度和垫料氮含量均无差异（P > 0.05）。
