Evaluation of true metabolizable energy for waterfowl
Article Abstract:
True metabolizable energy (TME) bioassays are a recent method determining the metabolizable energy (ME) content of waterfowl foods. The technique usually uses birds not provided with grit. A study aimed to determine if an accurate estimate of the TME of intact foods is provided with the use of grit-free birds. Corn, milo, wild millet and largeseed smartweed was fed to giant Canada geese both supplied with and denied grit. It was found that grit free birds could digest smartweed and milo more efficiently than grit supplied birds. Geese supplied with grit digested corn more efficiently when fed intact. It is recommended that experimental birds be provided with grit and fed intact foods, to achieve accurate TME estimates.

True metabolizable energy estimates of Canada goose foods
Article Abstract:
A new study investigates the nutritional value of eight foods commonly eaten by Canada geese. The true metabolizable energy (TME) of the food is estimated to provide a better understanding of its nutritional value. The eight foods tested are milo, corn, rice, soybeans, wild millet seeds, largeseed smartweed seeds, winter wheat foliage and chufa tubers. It is found that chufa tubers have the highest nutritional value, followed by milo, soybeans, wild millet, rice, winter wheat foliage and largeseed smartweed. Most of the variation in TME among foods was accounted for by crude fiber, which geese have a limited ability to digest.
