In last decade, the uncontrolled use of antibiotics as growth promoter for livestock has led to the appearance of antibiotic-resistant pathogens and increased risk of infectious diseases. This situation has triggered intensive research efforts to find safe alternative strategies. Certainly, the plants and vegetables and their derivatives as natural safe substances could be good candidates in th...
As the largest animal protein producer, poultry industry is within focus of mixed-diet consumers, as well livestock in general [...]
Background: Bioavailability is a good alternative to conventional physical and chemical methods for removing toxic metals from groundwater and wastewater. Methods: In this research, phenotypic and genotypic study was carried out on the use of isolated yeast from industrial effluents with the aim of eliminating Selenium biological and the production of biomass as a feed for livestock and poult...
Background and aim: Farmers that have occupational exposed to the organic dust, bacteria, endotoxin, mites, and fungi, as well as the hazardous gases such as ammonia, sulfides, hydrogen and nitrogen oxides, may be affected by allergic asthma, non-allergic rhinitis, and organic dust toxic syndrome.

These major changes in livesto...
background: combination of cyromazine as an insect growth regulator (igr) and nasonia vitripennis (hymenop tera: pteromalidae) a parasitic wasp may be an effective tool for reducing the house-fly populations in poultry houses and livestock farms. this study was conducted to assess the side effects of the igr cyromazine on the level of parasit ism and numbers and the longevity of emerged n. vitr...
