The influence of certain dietary fillers on the true metabolisable energy of diets for Turkeys

Abstract

1. An experiment was conducted with Large White turkey poults (0 to 3 weeks of age) to study the influence of dietary fillers on the true metabolisable energy (TME) of the diet.2. When 25 g sand/kg was substituted for the components of a basal diet, growth was not affected and the TME value of the diet was apparently higher than that of the basal diet, but not significantly so.3. The substitution of 50 g filler/kg (25 g sand plus 25 g grit/kg) resulted in a higher TME value than the substitution of either 25 g sand/kg or 25 g grit/kg, significantly so in the latter case.4. Substituting 25 g cellulose/kg resulted in a decrease in TME value, but not significantly so.

Measurement of Bioavailable Energy in Poultry Feedingstuffs: A Review

“…Tenesaca and Sell (1981) found the TME value of corn to decrease as dilution with silica gel increased and attributed the effect to the silica increasing F,,E+U.E. Individually sand and grir (25 g/kg) did not affect the TME value of a diet but in combination they increased TME whereas a cellulose supplement decreased the dietary TME value (Miles et al 1981). Sibbald (1981a) found no effect of cellulose or sawdust on F.E + U"E.…”
