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.

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 The Ovine Callipyge Locus: Iii. Genotypic Effects On Meat Quality Traits, B. A. Freking, J. W. Keele, S. D. Shackelford, T. L. Wheeler, M. Koohmarai, Merlyn K. Nielsen, Kreg A. Leymaster

Department of Animal Science: Faculty Publications

A resource flock of 362 F₂ lambs provided phenotypic and genotypic data to estimate effects of callipyge ( CLPG) genotypes (NN, NC, CN, and CC) on meat quality traits. The mutant allele is represented as C, the normal allele(s) as N, and the paternal allele of a genotype is given first. Lambs of each genotype born in 1994 and 1995 were serially slaughtered in six groups at 3-wk intervals starting at 23 wk of age. Warner-Bratzler shear force and subjective evaluation of marbling were collected during both years from longissimus. Calpastatin activity was measured on longissimus from the 1994 …

The Effect Of Forage Source And Particle Size On Finishing Yearling Steer Performance And Ruminal Metabolism, D. H. Shain, Rick Stock, Terry J. Klopfenstein, D. W. Herold

Department of Animal Science: Faculty Publications

Two finishing trials and a metabolism trial were conducted to evaluate the effect of forage source and particle size in dry-rolled corn finishing diets. In Exp. 1, 224 crossbred yearling steers (BW = 342 ± 11 kg) were used in a randomized complete block design consisting of seven treatments. Treatments were an all-concentrate diet or diets containing equal NDF levels provided by alfalfa hay or wheat straw (three treatments each) with each forage source ground to pass through a .95-, 7.6-, or 12.7-cm screen. Steers fed diets containing forage had greater ( P < .05) DMI than steers fed an all concentrate diet. Steers fed alfalfa diets gained faster ( P < .05) with a greater ( P < .05) concentrate efficiency than steers fed either all-concentrate or straw diets. In Exp. 2, 120 crossbred yearling steers (BW = 307 ± 2 kg) were used in a completely randomized design and fed dry-rolled corn diets containing 10% alfalfa ground to pass through either a .95- or 7.6-cm screen. Alfalfa particle size had no effect on performance or carcass measurements. In Exp. 3, six ruminally fistulated steers (BW = 508 ± 34 kg) were used in a 6 x 6 Latin square design and fed an all-concentrate diet or diets containing equal NDF levels provided by alfalfa hay, wheat straw, or ground corncobs with alfalfa and straw ground to pass through either a 2.54- or 12.7-cm screen. Steers fed straw diets spent more time ( P < .10) chewing than those receiving the other diets. In conclusion, forage particle size had no effect on finishing cattle performance or ruminal metabolism data. However, cattle consuming different forage sources in dry-rolled corn finishing diets may not respond similarly in animal performance.

Predicting Amount Of Compensatory Gain, Terry J. Klopfenstein, D. J. Jordon, Ivan G. Rush, Todd Milton

Nebraska Beef Cattle Reports

In North American beef production systems, the entire spectrum of restriction and compensation is found. The area of compensatory gain is complex and not well understood, but critically important to the economics of cattle feeding. Several compensatory gain studies from the University of Nebraska have been compiled. The range in compensation observed with cattle grazing season-long is 19-88 percent with a mean of 53 percent. From these grazing studies, days of restriction appear to be related to percentage compensation. In the feedlot, even relatively short restrictions trigger compensatory gain; however, feed efficiency response to compensatory gain is

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.

G99-1390 Altering Swine Manure By Diet Modification, Duane Reese, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explores options for altering the nitrogen and phosphorus content of swine manure.

There are situations in which it is necessary to change the nutrient content and/or the odor-producing potential of swine manure in order for pork production to thrive. For example, current Nebraska Department of Environmental Quality (NDEQ) permit procedures for livestock facilities require producers to document that sufficient land is available for crop use of the nitrogen (N) in manure. If sufficient land is not available for managing nutrients in manure, producers can alter the nitrogen and phosphorus content of swine manure by modifying the pig's diet. …

From Chiefly Provisioning To Commercial Fishery: Long-Term Economic Change In Arctic Norway, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Stratified farm mounds with excellent organic preservation in the Lofoten and Vesterålen islands in Arctic Norway provide a long-term record of changing human use of fish. In Arctic Norway, zooarchaeological signatures of intensive dried fish production extend back into the Iron Age, indicating a substantial role for cured cod prior to the beginning of the historical stockfish trade in c. AD 1200. North Norwegian chieftains of the late Iron Age and Viking periods clearly disposed of substantial staple surpluses of stockfish as well as the better documented prestige goods (furs and ivory). A comparative study of substantial collections spanning the …

Fuller And Language, Joseph Vining

Book Chapters

His style made him distinctive. His substance made him distinctive. The two crossed, were genetically related as we now say. Style and substance each drew on and was implied by the other. One point of their crossing was his sense of the nature of human language; what language was and could be, what it was not and could never be. In 1930, early in his work, Fuller took up the problem of language in a series of articles. Toward the end of his time he republished this initial ground-establishing effort as the little book we now have, Legal Fictions, …

Parasitic Helminth Genomics, M. Blaxter, M. Aslett, D. Guiliano, J. Daub, Steven A. Williams, Kunthala Jayaraman, Reda Ramzy, Alan Scott, Tania Supali, Barton Slatko

Biological Sciences: Faculty Publications

The initiation of genome projects on helminths of medical importance promises to yield new drug targets and vaccine candidates in unprecedented numbers. In order to exploit this emerging data it is essential that the user community is aware of the scope and quality of data available, and that the genome projects provide analyses of the raw data to highlight potential genes of interest. Core bioinformatics support for the parasite genome projects has promoted these approaches. In the Brugia genome project, a combination of expressed sequence tag sequencing from multiple cDNA libraries representing the complete filarial nematode lifecycle, and comparative analysis …

Effects Of Repeated Restraint Stress On Tissue Metabolism In Rats., Jun Zhou

LSU Historical Dissertations and Theses

It has been reported that repeated restraint stress (RS), 3 hours/day for 3 days, in rats caused sustained weight loss and a temporary drop in daily food intake with no subsequent compensatory overeating during the post stress period. The hypothesis tested in the present study is that RS causes peripheral tissue metabolism changes which account for the abnormal regulation of body weight and food intake during the post stress period. Adult male Sprague Dawley rats were assigned to control, pair fed (PF) or RS groups. One day after the end of RS, midbrain urocortin mRNA was at control levels in …

Influence Of Environment And Genotype On The Expression Of Host Plant Resistance In Sweet Potato To The Sweet Potato Weevil, Cylas Formicarius (Fab.)., Lixin Mao

LSU Historical Dissertations and Theses

Field and laboratory experiments were conducted to study the influence of environment and genotype on the expression of sweetpotato resistance to the sweetpotato weevil (SPW), Cylas formicarius (Fab.). Roots of four genotypes ("W-244", "W-250", "Beauregard", "Centennial") were evaluated for SPW feeding and oviposition at three different storage times. Roots from Louisiana, South Carolina and Mississippi were also evaluated. Genotype had a significant effect on feeding and oviposition. Storage time and production sites appeared to affect resistance expression; the outcomes depend on the genotypes. The effect of nitrogen on sweetpotato resistance to SPW was studied. Four genotypes were grown in the …

The Species Richness Of Birds Visiting A Yard Is Influenced By The Feeders/Seeds Present, David Joseph Horn

Journal of the Iowa Academy of Science: JIAS

Although seed preferences of species that visit bird feeders have been well documented, we know little about feeder/seed combinations most appropriate for attracting highest species richness or increasing abundance of individual species. I studied how the species composition of birds visiting a feeding station was influenced by addition of feeders filled with mixed seed, thistle, and suet in a yard that previously contained only a feeder with sunflower seeds. Addition of a seed mixture consisting of hulled sunflower, hulled peanuts, hulled millet, and hulled "tree" nuts in an elevated platform feeder increased species richness and total number of birds visiting …

The Habitat And Distribution Of The Stinkpot, Sternotherus Odoratus, In Iowa, Kristi K. Sutton, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Twenty years of study have shown that the stinkpot, Sternotherus odoratus and the Illinois mud turtle (Kinosternon flavescens spooneri) occur in Iowa primarily in the Mississippi Alluvial Plain. Even though the turtles are found within a kilometer of each other, they are never sympatric. Illinois mud turtles are most often associated with ephemeral ponds and soils of nearly pure sand (Sparta sand and Chelsea loamy fine sand), whereas stinkpots inhabit permanent water, often fed by cold springs, and are limited to sandy, loamy soils (Aquolls and Perks sandy loam). Even though several new localities have been discovered for stinkpots, population …
