Metabolizable energy and N-corrected ME (MEn) values of 12 samples of meat and bone meal (MBM) were determined using 288 barrows with an average BW of 35 +/- 3.1 kg. For each of 12 MBM samples, diets were formulated by substituting 0, 50, or 100 g/kg MBM (as-fed basis) in a basal 170 g of CP/kg corn-soybean meal diet; corn and soybean meal were adjusted at the same ratio to account for the subs...

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 ...

Three trials were conducted to study the effect of various levels of metabolizable energy (ME) on reproductive performance of crossbred gravid sows from breeding through gestation. One-hundred-one litters resulted from 124 sow matings during two summer and one winter trials over a 1 1/2-year period. Sows were fed 1.3 kg of a basal diet with additions of corn starch to provide 4,000, 5,000, 6,00...

The measured metabolizable energy (ME) of whole almonds has been shown to be less than predicted by Atwater factors. However, data are lacking on the effects of processing (roasting, chopping or grinding) on the ME of almonds. A 5-period randomized, crossover study in healthy individuals (n = 18) was conducted to measure the ME of different forms of almonds (42 g per day), as part of a controll...

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...
