The Effects Of Corn Coproduct Supplementation On Primiparous Cow Reproduction And Calf Performance, D. M. Larson, R. N. Funston

West Central Research and Extension Center, North Platte

An experiment was replicated over 2 yr to determine the effect of additional RUP and dietary fat from dried distillers grains plus solubles (DDGS; n = 2) or wet corn gluten feed (WCGF; n = 2) before breeding on primiparous cow reproduction and calf production. Over 2 yr, 134 postpartum, primiparous cows (429 ± 5 kg initial BW) were fed 1 of 2 isocaloric, approximately isonitrogenous diets in 1 pen/yr (n = 4) providing varying levels of RUP and dietary fat. Treatments were initiated 21 (yr 1) and 60 d (yr 2) postpartum and continued for 56 (yr 1) or …

A Comparison Of Melengestrol Acetate Fed At Two Dose Levels To Feedlot Heifers, G. E. Sides, J. T. Vasconcelos, R. C. Borg, O. A. Turgeon, W. C. Koers, M. S. Davis, K. Vander Pol, D. J. Weigel, C. M. Tucker

Panhandle Research and Extension Center

A randomized complete block design was used to compare the effects of feeding melengestrol acetate (MGA) at 0.4 (0.4M) and 0.5 (0.5M) mg/d per head on feedlot performance, estrus activity, and carcass characteristics of commercial beef heifers (n = 1,418; 10 pens/ treatment). Within 48 h of arrival at the research site, heifers were assigned to treatment, processed according to feedlot protocol, and administered an abortifacient. After adaptation to a 95% concentrate diet, MGA was supplied at either 0.4 or 0.5 mg/head daily. Estrus activity was monitored twice daily and summarized as a count of heifers showing estrus within a …

Panhandle Research and Extension Center

Eighty Angus and Angus × Simmental steer calves were used in a completely random design to determine the effect of rate of BW gain during the backgrounding period on subsequent feedlot performance, carcass characteristics, Warner-Bratzler shear force (WBSF), and sensory analysis. Animals were stratified by BW and allotted randomly to 1 of 10 pens (5 pens/treatment). Dietary treatments were formulated for an ADG of 0.91 kg/d [low BW gain (LG), 1.06 Mcal of NE_g/kg] diets and 1.25 kg/d [high BW gain (HG), 1.19 Mcal of NE_g/kg]. Steers were fed 70 d during the growing period. The …

Effect Of Feeding Melengestrol Acetate, Monensin, And Tylosin On Performance, Carcass Measurements, And Liver Abscesses Of Feedlot Heifers, G. E. Sides, R. S. S. Swingle, J. T. Vasconcelos, R. C. Borg, W. M. Moseley

Panhandle Research and Extension Center

Approximately 4,000 yearling heifers (initial BW = 306 ± 1.9 kg) were randomly allotted into 4 treatment groups to determine the effect of melengestrol acetate (MGA) on feedlot performance and carcass parameters. Treatments included a diet containing monensin (Rumensin) and tylosin (Tylan; RT) fed during the entire feeding period; RT plus MGA (RTM) also fed during the entire feeding period; RT withdrawn 35 d preslaughter (RTwd); and RTM withdrawn 35 d preslaughter (RTMwd). All cattle were implanted at arrival with Revalor-IH and reimplanted with Revalor-200, and were fed a standard feedlot finishing diet (that met or exceeded 1996 NRC requirements) …

Ec179 Managing Livestock Manure To Protect Environmental Quality, Michael A. Reynolds, Brian L. Benham, Richard B. Ferguson, Christopher G. Henry, Charles A. Shapiro, James P. Stack, Charles S. Wortman, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

Proper utilization of livestock manure is a major environmental concern. Livestock manure has typically been considered a ‘waste product’ of livestock production. A more accurate name for this material is a ‘recycled resource’ from the production of livestock. By managing livestock manure, the producer has a second chance to utilize the nutrients that have already been paid for but not fully utilized by the animal. Collecting, containing, and properly spreading livestock manure will incur additional costs for the producer. However, these costs can be offset or justified by the producer in terms of the yield enhancement and nutrient credits that …

Antioxidant Activities Of Purple Rice Bran Extract And Its Effect On The Quality Of Low Nacl, Phosphate-Free Patties Made From Channel Catfish (Ictalurus Punctatus) Belly Flap Meat, Byungrok Min, Ming H. Chen, Bartholomew W. Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Purple rice bran contains high amounts of natural antioxidants that consist of water- and lipid-soluble compounds. Hexane-insoluble and hexane-soluble fractions were separated from 100% methanolic extract from purple rice bran (RBE-HI and RBE-HS, respectively). Total anthocyanin, tannin, flavonoid, and phenolics contents were determined in those fractions, and their antioxidant capacities were evaluated by measuring 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical scavenging capability, oxygen radical absorbance capacity (ORAC), and iron chelating capability (ICC). RBE-HI and RBE-HSwere also added to restructured patties made fromminced channel catfish (Ictalurus punctatus) belly flap meat. Lipid oxidation, color, and/or textural properties were determined for raw and …

Systematics Of Ichneutine Parasitic Wasps (Braconidae: Ichneutinae), John Ray Fischer

Theses and Dissertations--Entomology

Ichneutine wasps have received little attention, despite their hypothesized placement at the base of an economically and ecologically important clade, the Microgastroidia s.s. This study combines previous hypotheses based on morphology with molecular evidence from multiple genes (28S: D1-5, 18S, COI, and CAD) to examine phylogenetic relationships of Ichneutinae using maximum parsimony and Bayesian inference. The three main ichneutine groups (Ichneutini, Muesebeckiini, and Proteropini) are each found to be monophyletic, but evidence exists that Ichneutinae itself is paraphyletic with respect to the rest of Microgastroidea s.l. Lispixys is found to be derived from within Oligoneurus, and Masonbeckia is almost …

Effect Of Using Threadfin Shad As Forage For Channel Catfish Fed Daily Or Every Third Day, Bartholomew W. Green, Peter Perschbacher, Gerald Ludwig

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We evaluated whether stocking threadfin shad Dorosoma petenense as a forage fish in multiple-batch production ponds for channel catfish Ictalurus punctatus could substitute for formulated feed when channel catfish were fed daily or every 3 d. A completely randomized design in a 232 factorial arrangement was used for the experiment, which was conducted in twelve 0.1-ha earthen ponds. Prespawn adult threadfin shad were stocked at 404 kg/ha in six of the ponds, whereas the remaining ponds received no threadfin shad. Channel catfish stockers (0.35 kg/fish) were stocked at 5,040 kg/ha, and fingerlings (28.2 g/fish) were stocked at 14,820 fish/ha. Channel …

The Impact Of Perceived Barriers To Export: An Analysis Of Kentucky Agricultural And Food Processing Firms, Kelly A. Davidson

University of Kentucky Master's Theses

As intra-industry trade increases in U.S. agricultural and food processing industries, the historical agricultural trade surplus is tightening. In efforts to maintain the trade surplus a focus has shifted towards the promotion of agricultural and processed food exports among small and medium sized firms. This study intends to identify and evaluate the potential for exports among small to medium sized agricultural and food processing firms in Kentucky through a collection of survey data. The objectives of this thesis are to identify the state’s product marketing opportunities and product specifications for international exports while identifying transaction requirements for potential exports.

Gathering Cows Using Virtual Fencing Methodologies, Dean M. Anderson, Marek Doniec, Carrick Detweiler, Iuliu Vesilescu, Daniela Rus, Barbara Nolen, Roy Libeau

School of Computing: Conference and Workshop Papers

Free-ranging livestock are classically controlled by herders. Holding, moving, or gathering free-ranging cattle requires flexible husbandry practices for efficient and effective lowstress animal management. Behavioral theory and practical experience indicates cattle can be taught to respond to auditory cues. Preliminary research has demonstrated that cows can be gathered autonomously using recorded audio cues associated with manual gathering. However, efficient gathering requires movement in the proper direction. Therefore, we believe using audio cues administered from directional virtual fencing (DVF™) equipment can facilitate proper animal orientation and facilitate the gathering of animals with minimal human intervention. Results from applying directional audio cues …

Isolation Of Mycobacterium Avium Subspecies Paratuberculosis Reactive Cd4 T Cells From Intestinal Biopsies Of Crohn’S Disease Patients, Ingrid Olsen, Stig Tollefsen, Claus Aagaard, Liv J. Reitan, J. P. Bannantine, Peter Andersen, Ludvig M. Sollid, Knut E.A. Lundin

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Background: Crohn’s disease (CD) is a chronic granulomatous inflammation of the intestine. The etiology is unknown, but an excessive immune response to bacteria in genetically susceptible individuals is probably involved. The response is characterized by a strong Th1/Th17 response, but the relative importance of the various bacteria is not known.

Methodology/Principal Findings: In an attempt to address this issue, we made T-cell lines from intestinal biopsies of patients with CD (n = 11), ulcerative colitis (UC) (n = 13) and controls (n = 10). The T-cell lines were tested for responses to various bacteria. A majority of the CD patients …

Functionally Similar Species Confer Greater Resistance To Invasion: Implications For Grassland Restoration, Stephen L. Young, Jacob N. Barney, Guy B. Kyser, Tracy S. Jones, Joseph M. Ditomaso

West Central Research and Extension Center, North Platte

Plant community functional composition can be manipulated in restored ecosystems to reduce the establishment potential of invading species. This study was designed to compare invasion resistance among communities with species functionally similar or dissimilar to yellow starthistle (Centaurea solstitialis), a late-season annual. A field experiment was conducted in the Central Valley of California with six experimental plant communities that included (1) six early-season native annual forbs (AF); (2) five late-season native perennials and one summer annual forb (NP); (3) a combination of three early-season native annual forbs and three late-season native perennials (FP); (4) six early-season non-native annual …
