The Nutritional Value of Poultry By-product Meal
for their nutritional content. The metabolizable energy of the samples (nitrogen corrected) could be predicted fairly accurately from the ash and protein 'contents of the ingredients. PBPM samples of relatively high and low qualities were incorporated into corn and soybean meal-based diets at the 5% level on an isoenergetic and isonitrogenous basis. Significant differences in chick growth or fe...
متن کاملMetabolizable Energy and Chemical Composition of Poultry by-Product Meal
This study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (PBPM) from two slaughterhouses in Iran. Samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. The amounts of calcium, phosphorus, sodium, potassium, Magnesium, Iron, Manganese, copper and Zinc were determined. The apparent metabolizable energy (...
متن کاملComparison of four feed proteases for improvement of nutritive value of poultry feather meal.
Feed industries are seeking new ways to cope with increased raw material costs, and one approach is to apply enzymatic treatment in the production of feed ingredients from animal by-products. Keratinases, a group of proteases, are capable of hydrolyzing keratin-rich material and have been applied in the production of cost-effective feather by-products for use as feed and fertilizers. The curren...
متن کاملDetermination of Apparent and True Digestibility of Poultry by Product Meal in Broiler Chickens
In order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, Ross 308 strain. Poultry by-product meal was prepared from two slaughter house in Alborz province. Samples were sent to laboratory for determination of chemical analysis. The birds received commercial broiler starter...
