Effect Of Dietary Phosphorus On Finishing Steer Performance, Bone Status, And Carcass Maturity, Galen Erickson, Terry Klopfenstein, C. T. Milton, D. Hanson, Chris Calkins

Department of Animal Science: Faculty Publications

Yearling crossbred steers (n = 60; 386 kg) were individually fed in a completely randomized experimental design to determine their P requirement. Treatments were in a factorial arrangement with two levels of Ca (.35 or .70% of DM) and five concentrations of P (.14, .19, .24, .29, or .34% of DM). The finishing diet consisted of 34.5% dry-rolled corn, 22.5% brewers grits, 22.5% corn bran, 7.5% ground corncobs, 5% molasses, 3% fat, and 5% supplement. Supplemental P was provided as monosodium phosphate and Ca as limestone. Ash content was determined on the first phalanx bone from the lower front legs …

Evaluation Of Nitrogen And Organic Matter Balance In The Feedlot As Affected By Level And Source Of Dietary Fiber, S. Bierman, Galen Erickson, Terry Klopfenstein, Rick A. Stock, D. H. Shain

Department of Animal Science: Faculty Publications

A trial was conducted to determine the effect of level and source of dietary fiber on N and OM excretion by cattle on finishing diets. One hundred twenty steers were stratified by weight and allotted to one of the following treatments: 7.5% roughage (7.5% R), wet corn gluten feed (WCGF; 41.5% of dietary DM), and all-concentrate (All Con) diet. Cattle were fed for 87 d during the summer with 23.7 m² of pen area per animal. Steers fed the WCGF diet had heavier final weights, greater DMI, and higher ADG ( P < .01) than the 7.5% R and All Con treatments. Steers fed All Con had lower ( P < .01) DMI than the other two treatments. Nitrogen and OM mass balances in the feedlot were quantified. Main components were nutrient input, retention, and excretion. Nitrogen and OM intake of steers fed WCGF were greater ( P < .05) than those of steers fed the other treatments. The WCGF treatment had a greater percentage of fecal N output ( P < .05). The All Con treatment had a greater ( P < .01) percentage of urinary N than WCGF and 7.5% R diets. Steers fed the WCGF treatment excreted more ( P < .01) OM compared with the other treatments, which led to more N and OM being removed in manure at cleaning. The All Con treatment had more ( P < .01) N and OM in runoff than the other treatments. Nutrition can change site of fermentation, which affects the composition of excreted material; however, total amount of N excreted may be more important than route of excretion in decreasing N losses to the environment and maximizing recovery in manure.

Review Of New Information On The Use Of Wet And Dry Milling Feed By-Products In Feedlot Diets, Rick Stock, J. M. Lewis, Terry J. Klopfenstein, C. T. Milton

Department of Animal Science: Faculty Publications

The processing of grains to produce human foods, beverages, or fuel ethanol has resulted in a wide variety of associated feed by-products. Hominy feed and distillers by-products are feed by-products associated with two distinctly different drymilling industries. Hominy feed contains approximately 57% starch, 11% CP, and 5% fat (DM basis). When fed to finishing cattle, hominy feed has approximately 87% the net energy value of corn. Distillers by-products contain 25 to 32% CP and 13 to 16% fat (DM basis). Wet distillers by-products have approximately 97 to 147% the net energy value of corn. The energy value of wet distillers …

Nf99-403 Livestock Waste Management Act (Revised March 2001), J. David Aiken

University of Nebraska-Lincoln Extension: Historical Materials

The Livestock Waste Management Act requires all livestock operations with 300 animal units or more to be inspected by the Nebraska Department of Environmental Quality (DEQ) to determine whether livestock wastes contaminate surface or ground water. This NebFact discusses the following parts of the Livestock Waste Management Act: Act (how cited); Terms (defined); Livestock operation, exemption, livestock waste control facility, permit, restriction; Construction permit or operating permit (when required), livestock waste control facilities, classification, restrictions; Section (how construed); Cold water class A streams (designation); Permit (acknowledgment required); Livestock operation (request inspection, when, fees, department, duties); Permits (duration, modification); Permit (application …

G99-1393 Grazing Alfalfa, Jerry D. Volesky, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Grazing alfalfa may be a cost efficient means of harvest for some producers. This NebGuide explores alfalfa and alfalfa/grass options, varieties and stand establishment, and grazing and bloat management.

Alfalfa is the most productive and versatile forage legume grown in Nebraska. Cutting for hay or silage has been the traditional method of harvest, but many opportunities and options exist for grazing. With current technology and proper management, beef gain can exceed 1,000 pounds per acre with acceptable stand persistence.

Mp99-40 The Economics And Control Of Insects Affecting Beef Cattle In Nebraska (Northern Great Plains), John B. Campbell, Gustave D. Thomas

University of Nebraska-Lincoln Extension: Historical Materials

Livestock insect control should be considered an integral part of an efficient beef herd health program.

This extension circular discusses the behavior and control of these major insect parasites of range and pasture cattle in Nebraska: stable fly, horn fly, face fly, cattle grubs, cattle lice, cattle scabies, horse and deer flies, mosquito, black fly, and biting midges (gnats).
