This experiment was conducted to compare the effect of litter amendments by using acidifier on growth performance, carcass characteristics and welfare of commercial broiler chicks along with its economical implication during winter season (DecemberJanuary months). A total of 180, day-old (Vencobb) broiler chicks were equally and randomly assigned to two litter abatements with alum and sodium bi...

Ammonia (NH3) volatilized from broiler litter diminishes indoor air quality, which can potentially decrease bird productivity. Emissions of NH3 exhausted from broiler houses pose environmental concerns for ecosystem biodiversity, aquatic nutrient enrichment, and particulate formation in the atmosphere. Research was conducted sampling litter (rice hull base) in 3 tunnel-ventilated commercial bro...

This study was conducted with the objective of evaluating the use of concrete or hard-packed dirt floor in broiler houses. This experiment was carried out in two different phases. The following performance parameters were studied: live weight, feed intake, feed conversion ratio, and mortality. Litter moisture, pH and temperature were measured. Litter residual contamination after cleaning and di...

a total of 448 ross 308 male broiler chickens were assigned to seven treatments with four replicates, each containing 16 chicks. the birds were reared from d 21 to 42 and effects of physical sizes (ad libitum by a basal commercial broiler diet with 3050 kcal/kg me and 19.06% cp/kg from 21 to 42 d. the chickens which received clinoptilolite (1.5% with particle size of 0.4-0.8 mm) showed a signif...

intestinal coccidiosis, caused by eimeria species, is an economically-important disease of poultry production industry worldwide. this study was designed to investigate the prevalence of different eimeria species in the farmed broilers of khoy city, west azarbaijan, north west iran. a total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. in...

In order to identify the phosphorus species and concentration in animal manure, we comparatively characterized phosphorus in dairy manure, swine manure, and broiler litter, using a sequential procedure, a simplified two-step procedure (NaHCO3/NaOH+EDTA), and a solution Phosphorus-31 Nuclear Magnetic Resonance (31P-NMR) spectroscopy procedure. In the sequential procedure, deionized water extract...

The reuse of poultry litter is a common practice in the Brazilian poultry industry for flocks of healthy chickens, due to 2 fundamental aspects: production cost and environmental sustainability. Litter is a potentially important source of infection for Salmonella, which requires characterization by microbiological analysis in different aspects of management and reuse. The objective of this stud...

Broiler flocks on two Dutch poultry farms were screened weekly for the presence of campylobacter in fresh caecal droppings during eight consecutive production cycles. Hatchery and fresh litter samples were taken at the start of each new cycle. Water, feed, insects, and faeces of domestic animals, present on the farms were also included in the sampling. Penner serotyping of isolates was used to ...

Value-added materials produced from broiler manure can be a renewable alternative to its problematic disposal. Pyrolysis of broiler manure (litter and cake) produces char, bio-oil, and biogas. In this study broiler manure chars were characterized for their ability to adsorb selected metal ions. Char yields for pelletized broiler manure slowly pyrolyzed at 700 and 800 °C for 1 h ranged between 2...
