متن کاملAmmonium Chloride and Ammonium Sulfate in Cattle Feedlot Finishing Rations
T WO levels of ammonium chloride or of ammonium sulfate were added to the rations of commercial feeder cattle. The rations were made isonitrogenous, essentially isocaloric and to contain the same level of calcium, phosphorus and salt. Total gains were essentially the same for all lots, varying only 15.6 lb (7.1 kg) over a 112 day feeding period. Feed conversion was increased only on the ration ...

متن کاملIsolation and stable nitrogen isotope analysis of ammonium ions in ammonium nitrate prills using sodium tetraphenylborate.
RATIONALE Because of the threat of bombings using improvised explosives containing ammonium nitrate (AN), law enforcement and intelligence communities have been interested in stable isotope techniques for tracking and discriminating AN sources. Separate analysis of the AN component ions ammonium and nitrate would add discriminatory power to these techniques. METHODS Ammonium ions in dissolved...
متن کاملExcimer laser fragmentation-fluorescence spectroscopy as a method for monitoring ammonium nitrate and ammonium sulfate particles.
Excimer laser fragmentation-fluorescence spectroscopy (ELFFS) is shown to be an effective detection strategy for ammonium nitrate and ammonium sulfate particles at atmospheric pressure and room temperature. Following photofragmentation of the ammonium salt particle, fluorescence of the NH fragment is observed at 336 nm. The fluorescence signal is shown to depend linearly on particle surface are...
