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 کاملTrue Metabolizable Energy of American Black Duck Foods
Understanding the true metabolizable energy (TME) of foods is critical to estimating the energetic carrying capacity of landscapes for migrating and wintering waterfowl.We estimated gross energy, nutrient composition, and TMEN (TME corrected for zero nitrogen balance) for 7 foods that are commonly found in the diet of American black duck (Anas rubripes) and other waterfowl wintering along the A...
متن کاملA bioassay for true metabolizable energy in feedingstuffs.
In 12 experiments with S.C.W.L. roosters it was shown that for each of 12 feedingstuffs there was a linear relationship between feed input and the amount of energy voided as excreta. In the 24 h. period, following 21 hr. of starvation, roosters receiving no feed excreted 4.07 kcal./kg. of body weight. When dextrose was fed the energy voided as excreta did not increase with dextrose input; conse...
متن کاملEffect of gestation metabolizable energy levels on sow productivity.
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...
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...
