To observe the influence of intestinal microbes on energy metabolism, male ICR strain germ-free (GF) mice, gnotobiotic (GB) mice, produced from GF mice monocontaminated with Staphylococcus epidermidis (Staph.) at three weeks of age, and conventional (CV) mice were used. Metabolizable energy, heat production and net energy (gain) per mouse were measured for three weeks when the mice were given 5...

The fixed metabolizable energy (ME) values from the NRC do not represent the true ME values of the various feedstuff used in livestock rations. Therefore, a rapid and effective method for evaluating the ME value of forage crops is required for proper ration formulation to improve production efficiency. Dairy goat digestion trials were conducted as the in vivo reference using the method of Menke...

I . The intake and excretion of total nitrogen, fat and the various forms of carbohydrate, and the heats of combustion of the diet, urine and faeces were measured in groups of young men, young women, elderly men and elderly women. 2. Each group was studied while the subjects were eating two diets in turn, which differed in their contents of unavailable carbohydrate; the young women were also st...

An extensively tacit understandings of equivalency between the deformed HeisenbergWeyl algebra in noncommutative space and the undeformed Heisenberg-Weyl algebra in commutative space is elucidated. Equivalency conditions between two algebras are clarified. It is explored that the deformed algebra related to the undeformed one by a non-orthogonal similarity transformation. Furthermore, non-exist...

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...
