Precise measurement of insecticide toxicity against house flies from various poultry ranches, dairies and cattle feed lots provided evidence of the presence of resistance roughly in proportion to the extent of insecticide use in each situation. The data indicate where changes to new insecticides are advisable, and illustrate how heavy reliance on insecticides over several years for fly control ...

Poultry as laboratory animals are economical, easy to house, manage and feed. Other birds may be used for special purposes. Where space is an important consideration, Japanese quail may prove ideal once supplies of this species are available freely. Most diseases common to birds can be overcome by good management, but drugs and antibiotics can also be used for controlling many of their specific...

The house fly, Musca domestica L., is a very important insect because of its role as a vector of several human, livestock, and poultry diseases. Different groups of insecticides, including the pyrethroids, are used to control house flies. The objective of the current study was to conduct a survey of the kdr insecticide resistance gene in the house fly population in the United Arab Emirates (UAE...

The aim of the presented study was to assess the exposure of poultry workers to airborne microorganisms, endotoxins and β-glucans during different stages of the chicken production cycle in 3 commercially-operated poultry houses. Personal and stationary sampling was carried out to assess exposure to both viable and total microbial aerosols. The stationary measurements of PM10 were performed to e...

It is well known that dietary protein affects the growth performance and carcass composition of poultry. Over the last several decades, numerous studies have been carried out to investigate to optimize the level of dietary protein since the protein is an important and expensive constituent in poultry feed. It is generally accepted that dietary protein should represent a balance of amino acids s...

Introduction The air of animal houses contains bioaerosols like viruses bacteria, fungi, endotoxins and allergens that present a health risk for humans and animals [1]. Airborne pathogen bacteria, fungi that cause allergies and endotoxins were detected in poultry houses [2]. The spreading of bioaerosol emissions from poultry houses is less understood and therefore it is difficult to estimate th...

BACKGROUND Highly pathogenic avian influenza A (H5N1) virus has been of public health concern since 2003. Probable risk factors for A(H5N1) transmission to human have been demonstrated in several studies or epidemiological reports. However, transmission patterns may differ according to demographic characteristics of the population and local practices. This article aggregates these data from thr...

Drug resistance is a problem wherever livestock are raised under intensive conditions and drugs are used to combat parasitic infections. This is particularly true for the anticoccidial agents used for the prevention of coccidiosis caused by protozoa of the apicomplexan genus Eimeria in poultry. Resistance has been documented for all the dozen or so drugs approved for use in chickens and varying...
