Apparent and true metabolizable energy values of feedstuffs for ducks.
Two experiments were conducted, each with 24 White Pekin ducks, to determine the AME and TME content of five feedstuffs for ducks. In each experiment, fasting losses were obtained from six ducks and six ducks were used for each feedstuff. Each experiment lasted 102 h with an initial 48-h period and a 54-h excreta collection period. During the first 48-h period, all birds were tube-fed dextrose ...
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 کاملRelationships among diet, metabolizable energy utilization and net energy values of feedstuffs.
A comparative slaughter experiment was conducted with beef steers to determine the energy utilization of six specific mixtures of a roughage basal and a concentrate basal diet. Of special interest were comparisons of relationships among metabolizable energy (ME) utilization, net energy values and diet composition. ME (kcal/g) was linearly related to proportion of roughage in the diet (r = -.96)...
متن کاملStereospecific analyses of several vegetable fats.
The distribution of fatty acids among the positions 1, 2, and 3 of triglycerides of seven vegetable fats has been determined. The fatty acid compositions in positions 1 and 3 are very similar in most cases, but in none of the fats is the distribution completely symmetrical.
متن کاملThe energy equivalents of ATP and the energy values of food proteins and fats.
Heats of combustion and energy equivalents of cytoplasmic ATP have been estimated for glucose, 101 food proteins and 116 food fats based on amino acid and fatty acid composition data from food composition tables and the heats of combustion and energy equivalents of cytoplasmic ATP of each individual amino acid, fatty acid, glycerol and glucose. The isodynamic equivalents of carbohydrate, fat an...
