Effects of sand versus sawdust as a litter bath substrate in furnished cages for laying hens were studied. The study used 112 Hy-Line White (HYW) and 140 Hy-Line Brown (HYB) layers housed in 18 furnished cages with 14 hens in each cage, generating 4 or 5 replicates per combination of genotype and litter substrate. Traits studied were mortality, feather cover, hygiene of hens, pecking wounds, he...

Tetracycline (TC) adsorption amount on original wood biochar was finitely, so modification is imperative to improve its capacity. This study mixed chinese fir sawdust with ammonium molybdate prepare a modified (MCB) via pyrolysis at 800 °C. Meanwhile, pristine (CB) produced as control. The effects of pH, time, initial concentration and adsorbent dosage the process were also studied. Langmuir mo...

This paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (MB) dye from aqueous solutions. Polyaniline coated onto sawdust (termedas PAn/SD) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (HC1) media. Adsorptionexperiments were carried out using batch system. The effec...
