Toxicity identification evaluation of landfill leachate taking a multispecies approach
In this study, the first phase of Toxicity Identification Evaluation (TIE) was used to characterise the major toxicants present in a Malaysian landfill leachate, using multispecies bioassay. Freshwater fish (Rasbora sumatrana), freshwater prawn (Macrobrachium lanchesteri) and tomato seeds (Lycopersicon esculentum) were chosen as test species based on local availability, as well as their broad s...
متن کاملFeeding Poultry Litter to Ruminants
Experiments were conducted to assess the feasibility of recycling poultry litter in the diets of young calves. Weaning rations containing 30% ensiled or unprocessed poultry litter gave unsatisfactory growth when fed to calves from two to twelve weeks of age. However, when these twelve week old calves were fed rations containing 30% or 50% poultry litter and sorghum, the costs/kg. gain were 19.5...
متن کاملManagement of Alum-Treated Poultry Litter
Previous research has shown that treatment of poultry litter with alum is an effective management strategy to reduce phosphorus (P) solubility in litter thereby reducing potential P losses to surface runoff after surface applications. However, limited data are available evaluating alum-treated poultry litter (ATPL) environmental impact in cultivated systems and how its application will affect c...

متن کاملDegradation of Roxarsone in Poultry Litter
Roxarsone (fig. 1), 3-nitro-4-hydroxyphenylarsonic acid, is an arsenic-containing feed additive that is used extensively in the broiler poultry industry to promote growth by controlling coccidial intestinal parasites. Most of the roxarsone is excreted unchanged (Morrison, 1969; Gregory, 1993) in the manure to accumulate in the poultry bedding. Each broiler excretes about 150 milligrams (mg) of ...
