Feed is the greatest single cost factor in pig production. In pig diets, energy accounts for the largest proportion of the cost. Therefore, it is critically important that the energy content of a diet is characterized in the best possible way. There are several systems available for the characterization of dietary energy. The most common ones digestible and metabolizable energy describe the ene...

The presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. In the present study, the feedstuffs were treated with acidified sodium chlorite (ASC) and its impact on  the microbial load and metabolizable energy availability was assessed in  the chickens. The effect of supplementation of feed grade enzyme was also evaluated...

Energy utilization in broilers as influenced by supplementation of enzymes containing phytase or carbohydrase activities was investigated. Day-old male broilers (480) were allocated to four slaughter groups, thirty broilers in the initial slaughter group and 150 broilers in each of the final slaughter groups on days 7, 14 and 21. Broilers in each of the final slaughter groups were allocated to ...

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...
