INTRODUCTION Campylobacter jejuni is the leading bacterial food-borne pathogen within the European Union, and poultry meat is an important vehicle for its transmission to humans. However, there is limited knowledge about how this organism persists in broiler litter and faeces. The aim of this study was to assess the impact of a number of environmental parameters, such as temperature, humidity, ...

Negative impacts on the environment, bird well-being, and farm worker health indicate the need for abatement strategies for poultry litter NH(3) generation. Type of bedding affects many parameters related to poultry production including NH(3) losses. In a randomized complete block design, 3 trials compared the cumulative NH(3) volatilization for laboratory-prepared litter (4 bedding types mixed...

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...

the purpose of this research was to evaluate the effects of litter chemical amendments on litter quality, broiler performance and carcass lesions (breast blisters, foot pad lesions and hock burns). in a 2×4 factorial experiment with 576 commercial broiler chicks (arian), the effect of two types of litter materials and three amendments were investigated using a completely randomized design with ...

The aim of this experiment was to evaluate the biomass yield and chemical composition of the essential oil of clove basil in response to doses of broiler litter (0, 5, 10, 15 and 20 t ha-1) added in presence of triple superphosphate (200 kg ha-1) or without it. Before the first harvest, the height of the plants increased significantly (34.42 cm) when 15 tonnes ha-1 broiler litter were added to ...

An alternative broiler litter to pine shavings may be switchgrass, a high yielding forage crop (8-12 tons per acre) that can grow across the Southeastern U.S. A study was conducted to determine the efficacy of chopped switchgrass as a litter material for broiler chickens. Pine Shavings (PS) and Switchgrass (SG) were used as litter treatments with 10 replications each. Body weight, body weight g...

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...

High levels of phosphorus and pathogens in runoff are 2 major concerns following manure applications to fields. Phosphorus losses from fields following manure applications have been linked to the solubility of phosphorus in manure; therefore, by decreasing manure phosphorus solubility, a decrease in phosphorus loss in runoff should be apparent. The objective of this research was to develop a pr...
