  • True Metabolizable Energy of moist-soil seeds
    Wildlife Society Bulletin, 2002
    Co-Authors: J.m. Checkett, Ronald D. Drobney, M.j. Petrie, D.a. Graber
    Abstract:

    Habitat objectives for migrating and wintering waterfowl are often established by converting population Energy demands into an equivalent measure of foraging habitat. In some areas, seeds produced from moist-soil plants provide a significant proportion of the Energy available to waterfowl. To accurately establish habitat objectives for migrating and wintering waterfowl, managers must estimate seed production from moist-soil plants and have information on Metabolizable Energy (ME) of moist-soil seeds. Although methods for estimating seed production have been developed, ME has been determined for few natural seeds. We determined true Metabolizable Energy (TME) of 10 moist-soil seeds commonly consumed by wintering and migrating ducks. TME estimates were similar (P>0.05) for hairy crabgrass (Digitaria sanguinalis; 3.09 kcal/g), little hairy crabgrass (D. ischaemum; 3.10 kcal/g), pigweed (Amaranthus spp.; 2.97 kcal/g), yellow foxtail (Setaria lutescens; 2.88 kcal/g), fall panicum (Panicum dichotomiflorum; 2.75 kcal/g), curly dock (Rumex crispus; 2.68 kcal/g), and wild millet (Echinochloa crusgalli; 2.61 kcal/g), but less (P

TME values determined for moist-soil seeds in this study will allow managers to accurately estimate carrying capacity of waterfowl habitats.

  • True Metabolizable Energy estimates of Canada goose foods
    The Journal of Wildlife Management, 1998
    Co-Authors: Mark J. Petrie, Ronald D. Drobney, David A. Graber
    Abstract:

    We determined true Metabolizable Energy (TME) and digestibility of 8 foods commonly available to Canada geese (Branta canadensis) in order to provide managers with a better understanding of the nutritional value of these foods. True Metabolizable Energy estimates were highest for chufa tubers (Cyperus esculentus ; 16.86 kJ/g), corn (Zea mays; 16.32 kJ/g), and milo (Sorghum vulgare; 15.72 kJ/g), while estimates for soybeans (Glycine max; 14.85 kJ/g), wild millet (Echinochloa crusgalli; 13.77 kJ/g), and rice (Oryza sativa; 11.76 kJ/g) were intermediate in value. Winter wheat foliage (Triticum aestivum; 10.04 kJ/g) and largeseed smartweed seeds (Polygonum pensylvanicum; 6.65 kJ/g) provided the least TME of foods tested. Crude fiber accounted for 76% of the variation in TME. Digestibility values of the 8 foods ranged from 35.1 to 88.5%, with digestibility varying widely among both agricultural and natural foods. To supply Canada geese with a balanced diet and foods high in Metabolizable Energy (ME), managers should provide a variety of agricultural and natural foods that are low in fiber content.

  • The Metabolizable Energy of Waxy vs. Normal Corn for Poultry
    Journal of Applied Poultry Research, 1997
    Co-Authors: David S. Ertl, Nick Dale
    Abstract:

    Abstract Waxy corn sometimes becomes available to the feed industry when its supply exceeds the demand of the wet milling industry. Several research papers in the past have evaluated the feeding value and/or Metabolizable Energy (ME) of waxy as opposed to normal corn. Unfortunately, several artifacts present in most of these studies complicate an interpretation of published data. True Metabolizable Energy (TMEn) assays were conducted on three sets of normal and waxy versions of the same corn hybrids. It was confirmed that corn hybrids vary in Metabolizable Energy. The TMEn of the three normal hybrids used in this study ranged from 3883 to 4024 kcal/kg (dry basis). However, results do not indicate a difference in TMEn of waxy vs. normal corn of the same hybrid. Thus, when formulating poultry rations with waxy corn, there is no reason to make any adjustment in Metabolizable Energy unless the specific hybrid is known to be low or high in caloric or protein value.

  • Metabolizable Energy of Meat and Bone Meal
    Journal of Applied Poultry Research, 1997
    Co-Authors: Nick Dale
    Abstract:

    Abstract Assaying meat and bone meal as separate fractions rather than complete meal yields substantially higher Metabolizable Energy (ME). Past research has indicated that elevated mineral levels in meat and bone meal depress the Metabolizable Energy of this ingredient under assay conditions. Samples of meat and bone meal from port and from beef origin were separated into “bone” and “meat + fat” fractions by chloroform flotation. When meat + fat fractions were assayed and an ME value estimated for residual protein and fat in the bone fractions, the Energy for samples of beef and of port meat and bone meals used in this study were 2449 kcal/kg (1115 kcal/lb) and 2847 kcal/kg (1275 kcal/lb, respectively (94% DM).

  • The Metabolizable Energy of Wheat By-Products
    Journal of Applied Poultry Research, 1996
    Co-Authors: Nick Dale
    Abstract:

    Abstract The composotion of wheat milling by-products varies markedly in different geographic regions among suppliers. In this study, the determined true Metabolizable Energy (TMEn) of 15 samples of wheat by-products, along with proximate composition and NDF, were investigated to develop prediction equations for estimating Energy values. Both crude fiber and NDF were found to be useful indicatorsof of the TMEn of wheat by-products.

  • True Metabolizable Energy of Corn Fractions
    Journal of Applied Poultry Research, 1994
    Co-Authors: Nick Dale, Donald Jackson
    Abstract:

    Abstract A series of studies was conducted to determine the relative Metabolizable Energy content of whole corn kernels, broken corn (BC), and foreign material (FM). Samples of yellow corn were obtained from eight different trains and separated into the three fractions which were assayed for proximate composition and nitrogen corrected true Metabolizable Energy. On average, whole kernels contained 3439 kcal/kg (86% dry matter), BC 2.5% less, and FM 11% less than intact kernels. Considerable variation was noted in the Energy of the FM fraction. The relatively modest reduction in Energy noted for the BC and FM fractions does not reflect the possible risks associated with insect and mod infestation of these fractions.

  • Metabolizable Energy Content of Poultry Offal Meal
    Journal of Applied Poultry Research, 1993
    Co-Authors: Nick Dale, Bryan I. Fancher, Mario E. Zumbado, Amable Villacres
    Abstract:

    Abstract Twenty-two samples of poultry offal meal were evaluated for proximate composition and nitrogen corrected true Metabolizable Energy (TMEn) content. Wide variations were noted in fat, ash, protein, and TMEn content, with the latter values ranging from 3626 kcal/kg (1648 kcal/lb) to 5247 kcal/kg (2385 kcal/lb). A prediction equation to estimate TMEn was developed based on fat and ash content.
