Eimeriosis is responsible for causing serious problems in poultry, mainly characterized by reduced weight gain and abnormalities of food conversion efficiency, thereby causing great economic losses. The aim of this study was to evaluate the epidemiology of eimeriosis in broiler chickens in the Araguaina region, State of Tocantins, Brazil. Samples from five farm properties were collected and sen...

IntroductIon In the last half century, significant increases in the productivity of modern poultry stocks have been achieved for both the meat and the egg production sectors of the global poultry industry. Synergies have resulted from advances made in all the major activities of poultry management and housing, nutrition and ration formulation, applying poultry genetics knowledge in commercial b...

There were no considerable up to date on the trace element requirements of commercial poultry in recent years in despite of the progress in their performance traits. One of the more prevalent problems in modern broiler production system which could be attributed to the trace mineral inadequacy is skeletal disorders. Zinc, is an essential trace element which acts as a co-factor in several metalo...

Garbage management represents a potential pathway of HPAI-virus infection for commercial poultry operations as multiple poultry premises may share a common trash collection service provider, trash collection site (e.g., shared dumpster for multiple premises) or disposal site (e.g., landfill). The types of potentially infectious or contaminated material disposed of in the garbage has not been pr...

Emergence and transmission of infectious diseases have an enormous impact on the poultry industry and present a serious threat to the health of humans and wild birds. Noncommercial poultry operations, such as backyard poultry facilities in China, are potential sources of virus exchange between commercial poultry and wild birds. It is particularly critical in wetland areas where backyard poultry...

The National Animal Health Monitoring System (NAHMS) Poultry '04 study was conducted to better describe non-commercial United States poultry populations, in particular, backyard and gamefowl breeder flocks. To estimate the density of backyard flocks in close proximity to commercial operations, a sample of 350 commercial poultry operations in 18 top poultry producing states was selected from the...

Rural poultry farming is common in the Northern provinces. Similar to commercial poultry, rural poultry is susceptible to most infectious diseases. In addition, by increasing the density of poultry farming, the probability of disease incidences has been increased. Newcastle disease is the most highly infectious disease which is endemic in Iran and causes outbreaks among commercial and rural pou...

Poultry litter application to fields that will be cropped to legumes is desirable because legumes biologically fix N2 gas from the atmosphere, allowing manures to be applied at rates needed only to satisfy crop P and/or K requirements. The need to export the nutrients in poultry litter from western Arkansas to areas of intensive cropping and fertilizer use plus recent increases in commercial fe...

The global poultry sector is divided into a large-scale commercial sector dominated by international, highly vertically integrated companies, and a small-scale sector that provides up to 90 percent of total poultry production in some of the least developed countries. The fast reproduction cycle, low unit costs, economies of scale in research and appropriation and control of the produce are driv...
