Abstract

We studied the effect of five bedding materials (wood shavings, sawdust, peanut hulls, wheat straw and shredded paper) and PLTtrade mark (a commercial formulation of Na bisulfate) in factorial combinations, on NH(3) emissions from broiler manure. Treatments were incubated for 11 days at 25 degrees C and 98% relative humidity. Ammonia was trapped in 0.1N H(2)SO(4) and measured colorimetrically as NH(4)(+), and CO(2) was monitored with an infrared analyzer. Ammonia and CO(2) emissions were suppressed by PLT throughout the study. Wheat straw, wood shavings, and sawdust, with C(total)/N(total)>50 or C(biodegradable)/N>20, had low NH(3) emissions. Total NH(3) emissions from peanut hulls and shredded paper were the highest, probably due to peanut hulls' low C/N ratio and shredded paper's alkaline pH. No significant interactions on NH(3) emissions were detected between PLT and bedding materials.

摘要

我们研究了五种垫料（刨花、锯末、花生壳、麦秸和碎纸）与PLT商标产品（一种硫酸氢钠商业配方产品）的析因组合对肉鸡粪便氨排放的影响。将各处理在25℃和98%相对湿度下孵育11天。氨被捕集在0.1N硫酸中，并通过比色法测定为铵离子，二氧化碳则用红外分析仪进行监测。在整个研究过程中，PLT抑制了氨和二氧化碳的排放。总碳/总氮>50或可生物降解碳/氮>20的麦秸、刨花和锯末的氨排放量较低。花生壳和碎纸的总氨排放量最高，这可能是由于花生壳的碳氮比低以及碎纸的碱性pH值所致。未检测到PLT与垫料之间在氨排放方面存在显著交互作用。
