True Metabolizable Energy and Dry Matter Contents of Some Feedstuffs

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 ...

Application of Mathematical Models to Estimate Metabolizable Energy Contents of Energetic Concentrate Feedstuffs for Poultry

A study using 51 wheat, 56 barley and 34 oat grain samples was conducted to investigate the feasibility of predicting the apparent metabolizable energy (AME) value of these cereals for poultry. Stepwise regression analyses were performed to evaluate the relationship of AME with starch, ether extract (EE), crude fiber (CF), soluble sugar (SS), ash and crude protein (CP) (for wheat and barley gra...

Comparison of in vitro Gas Production, Nutritive Value, Metabolizable Energy and Organic Matter Digestibility of some Chickpea Varieties

This study was carried out to determine the nutritional value of different chickpea varieties using in vitro gas production technique.As a result, significant variations in terms of chemical composition, gas production rate and metabolizable energy, net lactation energy and digestible organic matter were found among the 8 different chickpea varieties. The crude protein contents of chickpea vari...

Relationships 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)...
