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 ...
متن کاملMetabolizable Energy in Feeding Systems for Pigs and Poultry
The major consideration in this paper is the suitability of a metabolizable energy system for pigs. For poultry there is no practical alternative since urine and faeces are voided conjointly. The correction to digestible energy of a feedstuff for energy in urine is usually small, but there are circumstances when this may be large. Furthermore there are insufficient data on metabolizable energy ...
متن کاملMetabolizable Energy in Feeding Systems for Grazing Animals in Australia
Attention is drawn to several comparisons of the ARC feeding system with other systems. Recent Australian adaptations of ME standards for drought feeding of sheep and for cattle feeding are described. There is a need to adapt any feeding standards to the biology of the pastoral system. It is concluded that the Australia-wide adoption of ME based feeding standards would be helpful in promoting a...
متن کاملRecent Developments in the Metabolizable Energy Feeding System for Ruminants
Equations presented predict the metabolizable energy (ME) content of feeds, and ME requirements for maintenance and production. New approaches are described for defining the maintenance requirements of penned and grazing animals, and the composition and energy of liveweight gains. The latter employs the concept of a Standard Reference Weight (SRW) to characterise the various breeds of cattle an...
متن کاملImproved prediction of meat and bone meal metabolizable energy content for ducks through in vitro methods.
Apparent metabolizable energy (AME) of meat and bone meal (MBM) for poultry is highly variable, but impractical to measure routinely. Previous efforts at developing an in vitro method for predicting AME have had limited success. The present study uses data from a previous publication on the AME of 12 MBM samples, determined using 288 White Pekin ducks, as well as composition data on these sampl...
