DIGESTIBLE ENERGY IN FORAGE BYIN VIVOANDIN VITROASSAYS

Digestible energy requirements for exercising horses.

A method to estimate digestible energy in horse feed.

Predicting digestibility is a basic step for energy evaluation in horse feed. In horses, as in all species where microbial fermentation plays an important role in digestion, interactions between feed ingredients are even more important than those in other species. In horses suggestions for systems of energy evaluation usually refer to all feedstuffs and they are not limited to certain life stag...

Digestible and metabolizable energy of crude glycerol for growing pigs.

The apparent DE and ME values of crude glycerol for growing pigs were determined in 5 experiments using crude glycerol (86.95% glycerol) from a biodiesel production facility, which used soybean oil as the initial feedstock. Dietary treatments were 0, 5, or 10% glycerol addition to basal diets in Exp. 1; 0, 5, 10, or 20% glycerol addition to basal diets in Exp. 2; and 0 and 10% crude glycerol ad...

Effect of dietary digestible energy level on growth indices of kutum (Rutilus frisii kutum Kamenskii, 1901)

A 60-days feeding trail was conducted to evaluate the effects of dietary digestible energy levels (DE) on kutum, Rutilus frisii kutum. Four is nitrogenous (35% protein) diets with digestible energy levels of 2500, 2600, 2700 and 2800kcal kg-1 was tested. Two hundred and forty advanced fry (2±0.4g) were randomly distributed in 12 fiberglass tanks of 400L capacity. Nutritional responses in terms ...

Forage fiber effects on particle size reduction, ruminal stratification, and selective retention in heifers fed highly digestible grass/clover silages.

The objective of this study was to investigate the effect of NDF content in highly digestible grass/clover silage on particle size reduction, ruminal stratification, and selective retention in dairy heifers. The reduction in particle size from feed to feces was evaluated and related to feed intake, chewing activity, and apparent digestibility. Four grass/clover harvests (Mixtures of Lolium pere...
