Metabolizable 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 کاملMetabolism of dehydroretinyl ester in White Leghorn chicks.
1. The metabolism of dehydroretinyl ester has been studied in vitamin-A-deficient white leghorn chicks. Dehydroretinyl ester was metabolized to 3-hydroxyretinol diester, 3-hydroxyanhydroretinol and rehydrovitamin A2 which were isolated from the intestines and livers of chicks. 2. The metabolism of 3-hydroxyretinol diester and 3-hydroxyanhydroretinol, which were immediate metabolites of dehydror...
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...
متن کاملThe 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...
