three artificial neural networks (ann) models; general regression neural network (grnn), redial basis function (rbf) and three layer multiple perceptron network were carried out to evaluate the prediction of the apparent metabolizable energy (ame) of wheat and corn from its chemical composition in broiler. input variables included: gross energy (ge), crude protein (cp), crude fiber (cf), ether ...

Limited data are available to describe the different phases of dietary protein and energy utilization in growing cattle as compared with those in adult cattle or in growing nonruminants. The European data on this topic are summarized to indicate application in appropriate feeding standards. Net protein requirements are widely variable with breed and sex. They are lower in steers than in bulls a...

A series of assays were conducted to determine to the available energy of several meat and bone meal products by various methods. The correct determination of the energy available to poultry from these products is important for accurate diet formulation and product usage. Several methods for determining energy availability are utilized, including true metabolizable energy (TME) and excreta and ...

in the first experiment, the chemical composition, apparent metabolizable energy (ame), ame corrected for nitrogen (amen), true metabolizable energy (tme), tme corrected for nitrogen (tmen) values of the sweet almond meal were determined in adult leghorn cockerels. the second experiment was performed to evaluate the effects of different levels of sweet almond meal at 0, 100, 200 and 300 g/kg on...

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P
