This experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (PBPM) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. Three samples of PBPM produced in Ardabil province located in northwest of Iran, were provided during one month sampling peri...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Quail production is steadily gaining importance in developing countries like Uganda, particularly in urban and peri-urban areas. However, inappropriate feeding practices such as using the same feed classes across different growth stagesor beyond the recommended growth stageshave been reported among quail farmers. This study evaluated the nutritional properties of quail diets used in urban and p...
determining the prevalence of saprophyte fungi in agricultural products and processed foods used in the poultry diet is important. these studies lead to an overall control plan and prevention of fungal infection in different stages of harvesting, transportation and storage. most of aspergillus species grow at ambient temperature. some species can produce toxins in the diet of birds; thus, speci...
Cassava root meal which has been used as good alternative energy source in poultry and pig diets is increasingly becoming an important energy source for feeding the world’s human population. There are however, several by-products of cassava harvest ranging from the leaves, peels and pulp which have potential as feed ingredients in poultry rations. Cassava peels and pulps are moderate to high in...
A considerable amount of research has been conducted on the effects of feeding DDGS to poultry. Corn DDGS is an excellent feed ingredient for use in layer, broiler, duck and turkey diets and contains approximately 85% of the energy value in corn, has moderate levels of protein and essential amino acids, and is high in available phosphorus. Layer and broiler diets can easily contain up to 10% DD...
