discordant detection of avian influenza virus subtypes in time and space between Poultry and wild birds towards improvement of surveillance programs
PLOS ONE, 2017Co-Authors: Josanne H Verhagen, Pascal Lexmond, Oanh Vuong, Martin Schutten, Judith Guldemeester, Albert D M E Osterhaus, A R W Elbers, Roy Slaterus, Menno Hornman, Guus KochAbstract:Avian influenza viruses from wild birds can cause outbreaks in Poultry, and occasionally infect humans upon exposure to infected Poultry. Identification and characterization of viral reservoirs and transmission routes is important to develop strategies that prevent infection of Poultry, and subsequently virus transmission between Poultry holdings and to humans. Based on spatial, temporal and phylogenetic analyses of data generated as part of intense and large-scale influenza surveillance programs in wild birds and Poultry in the Netherlands from 2006 to 2011, we demonstrate that LPAIV subtype distribution differed between wild birds and Poultry, suggestive of host-range restrictions. LPAIV isolated from Dutch Poultry were genetically most closely related to LPAIV isolated from wild birds in the Netherlands or occasionally elsewhere in Western Europe. However, a relatively long time interval was observed between the isolations of related viruses from wild birds and Poultry. Spatial analyses provided evidence for mallards (Anas platyrhynchos) being more abundant near primary infected Poultry farms. Detailed year-round investigation of virus prevalence and wild bird species distribution and behavior near Poultry farms should be used to improve risk assessment in relation to avian influenza virus introduction and retarget avian influenza surveillance programs.

Use of Poultry pre-cooked slaughterhouse waste as ruminant feed to prevent environmental pollution
Journal of Cleaner Production, 2017Co-Authors: Mehdi Kazemi-bonchenari, Alireza Alizadeh, Leila Javadi, Mohammad Zohrevand, Nicholas E. Odongo, Abdelfattah Z.m. SalemAbstract:Abstract The generation of Poultry slaughterhouse waste from Poultry production is not only unavoidable but the amount and kinds of waste can cause environmental problems. In the present study, the potential rumen digestion of Poultry slaughterhouse waste which consists of protein-rich organic residues was evaluated. The chemical composition, amino acid profile and Cornell Net Carbohydrate and Protein System fractions of these wastes was determined. Rumen digestion of Poultry slaughterhouse waste was compared with two common protein sources (fish meal and roasted soybean). Three Poultry slaughterhouse waste samples were collected from industrial Poultry slaughter-houses and the in situ degradation was done using rumen cannulated sheep. The protein (50–63%), ether extracts (18–27%) and ash (9–15.5%) contents of different Poultry slaughterhouse waste samples were different (P

Poultry waste management agricultural and environmental issues
Advances in Agronomy, 1994Co-Authors: J T Sims, D C WolfAbstract:Publisher Summary This chapter focuses on the development of management programs that meet the increasing demand for Poultry products, while minimizing the environmental effects of Poultry wastes on soils, crops, surface waters, and groundwaters. A description of the types and compositions of Poultry wastes, and a review of recent research addressing the agricultural and environmental aspects of Poultry waste management are discussed in the chapter. Effective environmental management of any Poultry waste begins with an understanding of its composition and the physical, chemical, and microbiological reactions that control the fate of potential pollutants in the waste following land application. The three most common Poultry wastes are Poultry manure or Poultry litter, dissolved air flotation (DAF) sludge originating from Poultry processing plants, and composts produced from hatchery wastes and dead birds. The major Poultry production operations include broiler chickens, turkeys, and eggs. Two types of confinement housing are commonly used for Poultry operations: caged pit systems and floor/litter systems. Land application of animal waste is an important management practice to recycle nutrients, to improve or maintain soil fertility, and to improve soil biological and physical properties. The components of an effective waste management program for the agricultural use of organic wastes include site selection; production and collection; storage, handling, and treatment; transfer and application; and utilization.
