Endogenous energy, a cause of biased true metabolisable energy values

  • 1981
  • Issue: 3
  • Volume: 11
J.J. du Preez, J.P. Hayes & J.S. Duckitt Page: 269 - 272

Generally fasted birds are used for estimating endogenous energy (EE) excretion, this measurement being a critical factor in determining the TME of feeds and ingredients. Evidence is presented that EE is overestimated because the fasted birds lack energy during the…

Determination of metabolisable energy of five cultivars of hulless barley using adult Leghorn cockerels (Short communication)

  • 2008
  • Issue: 1
  • Volume: 38
M. Rezaei, M. Dehghan and M. Ayatollahy Page: 28 - 30

Hulless barley contains more digestible nutrients than do whole barleys due to a lower content of indigestible fibre, but also contains a higher concentration of ß-glucans. The chemical composition and apparent metabolisable energy (AME) of five cultivars (3, 7, 12,…
