Pollen Concentration Analysis Of Ancestral Pueblo Dietary Variation, Karl J. Reinhard, Sherrian Edwards, Teyona R. Damon, Debra K. Meier

Department of Anthropology: Faculty Publications

Previous coprolite research on the Colorado Plateau has shown that macrofossils are a useful way of statistically demonstrating prehistoric dietary variation of Ancestral Pueblos (Anasazi). Up until now, pollen concentration from human coprolites has not been used for comparative, statistical study. We present here the statistical analysis of pollen concentration values of coprolites from two Ancestral Pueblo sites, Salmon Ruin and Antelope House. The data show that although most pollen types do not show statistically significant variation, there are some types that show how different Ancestral Pueblo populations adapted to plant resources in different environments. The analysis indicates that future …

Success In Identification Of Experimentally Fragmented Limb Bone Shafts: Implications For Estimates Of Skeletal Element Abundance In Archaeofaunas, Travis Rayne Pickering, Charles P. Egeland, Amy G. Schnell, Daniel L. Osborne, Jake Enk

Department of Anthropology: Faculty Publications

A strong pattern of high hindlimb representation (especially tibiae) was recognized in our survey of zooarchaeological analyses that included limb bone shafts in estimates of element abundance in assemblages from the Old and New Worlds, from widely spread time periods and with various hominid species that acted as bone accumulators. Inter-element differences in bone mineral density and carcass transport behavior by hominids do not explain the pattern satisfactorily. We hypothesized that shaft fragments of hindlimb elements (especially tibiae) might be more “intrinsically identifiable” than are fragments from other limb bones, and constructed an experiment to test this idea. Whole limb …

Wet Corn Gluten Feed And Alfalfa Hay Levels In Dry-Rolled Corn Finishing Diets: Effects On Finishing Performance And Feedlot Nitrogen Mass Balance, T. B. Farran, Galen E. Erickson, Terry Klopfenstein, C. N. Macken, R. Lindquist

Department of Animal Science: Faculty Publications

One-hundred ninety-two crossbred steers (initial BW= 351 ± 11 kg) were used to determine the effects of removing alfalfa hay (AH) from dry-rolled corn-based diets containing wet corn gluten feed (WCGF) on animal performance and nutrient (N and OM) mass balance in open feedlot pens. Steers were stratified by weight and assigned randomly to 24 pens (2 × 3 factorial) and fed for 132 d from June to October 2002. Experimental diets contained either 0 or 35% WCGF and 0, 3.75, or 7.5% AH, and were formulated to be isonitrogenous. For efficiency of gain, an interaction occurred (P = 0.09) …

Evaluation Of Average Daily Gain Prediction By Level One Of The 1996 National Research Council Beef Model And Development Of Net Energy Adjusters, H. C. Block, Terry Klopfenstein, Galen E. Erickson

Department of Animal Science: Faculty Publications

Two data sets were developed to evaluate and refine feed energy predictions with the beef National Research Council (NRC, 1996) model level 1. The first data set included pen means of group-fed cattle from 31 growing trials (201 observations) and 17 finishing trials (154 observations) representing over 7,700 animals fed outside in dirt lots. The second data set consisted of 15 studies with individually fed cattle (916 observations) fed in a barn. In each data set, actual ADG was compared with ADG predicted with the NRC model level 1, assuming thermoneutral environmental conditions. Next, the observed ADG (kg), TDN intake …

Estimation Of Undegradable Intake Protein In Forages Using Neutral Detergent Insoluble Nitrogen At A Single In Situ Incubation Time Point, H. L. Haugen, M. J. Lamothe, Terry J. Klopfenstein, Don C. Adams, M. D. Ullerich

Department of Animal Science: Faculty Publications

Two experiments were conducted to evaluate the use of neutral detergent insoluble nitrogen (NDIN) at a single in situ incubation time point to estimate the undegradable intake protein (UIP) in forages as well as to compare rates of NDIN degradation. Forage samples in Exp. 1 comprised diet samples collected from range and meadow pastures monthly from May through September. In Exp. 2, clipped samples of alfalfa, birdsfoot trefoil, kura clover, and smooth bromegrass, and diet samples of the mixed legume-grass and smooth bromegrass were evaluated. Forage samples were incubated in situ for their mean retention time (MRT) estimated from IVDMD …

Determination Of Undegradable Intake Protein Digestibility Of Forages Using The Mobile Nylon Bag Technique, H. L. Haugen, S. K. Ivan, James C. Macdonald, Terry J. Klopfenstein

Department of Animal Science: Faculty Publications

Two experiments were conducted using 2 ruminally and duodenally fistulated steers to determine the digestibility of undegradable intake protein (UIP) of smooth bromegrass (Bromis inermis), birdsfoot trefoil (Lotus coniculatus L.), and heat-treated alfalfa (Medicago sativa) using the mobile nylon bag technique. Undegradable intake protein was determined using neutral detergent insoluble CP at a single in situ incubation time point based on 75% of the total mean retention time estimated from IVDMD plus a 10-h passage lag. In Exp. 1, UIP (% DM) of smooth bromegrass in June and July were 1.82 and 1.71, respectively (P …

Effects Of Growth-Promoting Agents And Season On Blood Metabolites And Body Temperature In Heifers, Terry L. Mader, W. M. Kreikemeier

Department of Animal Science: Faculty Publications

To assess the efficacy of growth-promoting agents among seasons, triiodothyronine (T₃), thyroxine (T₄), plasma urea nitrogen (PUN), IGF-I, and tympanic temperature (TT) were measured in summer and winter studies. Heifers (n = 9/pen) were allotted to 12 pens in both December and June. Pens were assigned to 1 of 6 growth promotant treatments: control (no growth promotant), estrogenic implant (E), trenbolone acetate implant (TBA), E + TBA (ET), melengestrol acetate (MGA), and ET + MGA (ETM). Blood samples were collected from 4 heifers per pen per study on d 0, 28, 56, and 84 via jugular …

Technical Note: Estimating Statistical Power Of Mixed Models Used In Dairy Nutrition Experiments, Paul J. Kononoff, Kathryn J. Hanford

Department of Animal Science: Faculty Publications

Statistical power is defined as the probability of correctly rejecting the null hypothesis. Power calculations may be useful in planning experiments. The objective of this technical note is to outline an applied method that estimates statistical power of a dairy nutrition experiment that employs a Latin square as the experimental design. Because the SAS MIXED procedure (PROC MIXED) is commonly used to analyze data sets, this note outlines basic programming procedures that may be used to estimate statistical power of a mixed model using this procedure.

Effects Of Pre- And Postpartum Nutrition On Reproduction In Spring Calving Cows And Calf Feedlot Performance, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein, D. M. Feuz, Richard N. Funston

Department of Animal Science: Faculty Publications

Crossbred, spring-calving cows (yr 1, n = 136; yr 2, n = 113; yr 3, n = 113) were used in a 3- yr experiment to evaluate the influence of supplemental protein prepartum and grazing subirrigated meadow postpartum on pregnancy rates and calf feedlot performance. A 2 × 2 factorial arrangement of treatments was used in a switchback design. From December 1 to February 28, cows grazed dormant upland range in 8 pastures (32 ± 2 ha each). The equivalent of 0.45 kg of supplement/cow per d (42% CP) was provided to half of the cows on a pasture basis …

Benchmarking Carcass Characteristics And Muscles From Commercially Identified Beef And Dairy Cull Cow Carcasses For Warner-Bratzler Shear Force And Sensory Attributes, A. M. Stelzleni, L. E. Patten, D. D. Johnson, Chris R. Calkins, B. L. Gwartney

Department of Animal Science: Faculty Publications

The objective of this study was to benchmark carcasses and muscles from commercially identified fed (animals that were perceived to have been fed an increased plane of nutrition before slaughter) and nonfed cull beef and dairy cows and A-maturity, USDA Select steers, so that the muscles could be identified from cull cow carcasses that may be used to fill a void of intermediately priced beef steaks. Carcass characteristics were measured at 24 h postmortem for 75 carcasses from 5 populations consisting of cull beef cows commercially identified as fed (B-F, n = 15); cull beef cows commercially identified as nonfed …

Department of Animal Science: Faculty Publications

To determine sensory preference and value of fresh beef steak differing in aging technique, strip steaks were evaluated by consumers in Denver (n = 132 consumers) and Chicago (n = 141 consumers). Wet-aged Choice strip loins were matched with dry-aged Choice strip loins, whereas wet-aged Prime strip loins were matched with dry-aged Prime strip loins. Dry-aged strip loins were commercially aged in air in a controlled environment for 30 d and vacuum-aged for 7 d during shipping and storage. Wet-aged strip loins were vacuum-packaged and aged for 37 d in a 1°C cooler. Pairs of strip loins were matched to …

The Effect Of Carbohydrate Source On Nitrogen Capture In Dairy Cows On Pasture, A. M. Gehman, J. A. Bertrand, T. C. Jenkins, B. W. Pinkerton

Department of Animal Science: Faculty Publications

The objective of this study was to determine if feeding carbohydrate supplements with faster degradation rates than corn to dairy cows grazing ryegrass would improve nitrogen capture, milk production, and components. Treatments were grain supplements based on: 1) corn (CORN), 2) barley and molasses (BM), or 3) citrus pulp and molasses (CM). For BM and CM, the diet composition was the same as that of CORN except that a portion of the corn was replaced with barley and molasses or citrus pulp and molasses, respectively, on a dry matter basis. Cows grazed ryegrass (Lolium multiflorum Lam.) pasture. Yield of …

Milk Production Of Dairy Cows Fed Wet Corn Gluten Feed During The Dry Period And Lactation, Paul J. Kononoff, S. K. Ivan, W, Matzke, R. J. Grant, R. A. Stock, Terry J. Klopfenstein

Department of Animal Science: Faculty Publications

An experiment was conducted with 36 primiparous and 40 multiparous Holstein cows to examine the effects of feeding wet corn gluten feed (WCGF) on 305- d milk production, dry matter (DM) intake, body condition score (BCS), and health. The experimental treatments included: 1) control—WCGF not fed (n = 27); 2) WCGF-L—cows received diets containing WCGF (38% DM basis) during lactation (n = 23); and 3) WCGFDL— cows received diets containing WCGF (38% DM basis) during the dry period and lactation (n = 26). During the dry period, cows consuming WCGF were observed to have a significant gain in BCS (0.07 …

Seven commercially available corn hybrids representing a range in kernel traits were evaluated for a variety of chemical and physical traits that included test weight, 1,000-grain weight, kernel size, starch, CP, amylose, Stenvert Hardness tests (kernel hardness traits), tangential abrasive dehulling device loss, 12-h in vitro starch disappearance, and rate and extent of in situ DM disappearance. Differences among hybrids existed for all physical kernel traits measured. In Exp. 1, 224 steers in 28 pens were fed the same …

Influence Of Lysobacter Enzymogenes Strain C3 On Nematodes, J. Chen, W. H. Moore, Gary Yuen, D. Kobayashi, E.P. Caswell-Chen

Department of Plant Pathology: Faculty Publications

Chitinolytic microflora may contribute to biological control of plant-parasitic nematodes by causing decreased egg viability through degradation of egg shells. Here, the influence of Lysobacter enzymogenes strain C3 on Caenorhabditis elegans, Heterodera schachtii, Meloidogyne javanica, Pratylenchus penetrans, and Aphelenchoides fragariae is described. Exposure of C. elegans to L. enzymogenes strain C3 on agar resulted in almost complete elimination of egg production and death of 94% of hatched juveniles after 2 d. Hatch of H. schachtii eggs was about 50% on a lawn of L. enzymogenes strain C3 on agar as compared to 80% on a lawn of E. coli …

Evaluation Of The Single Kernel Characterization System (Skcs) For Measurement Of Sorghum Grain Attributes, S. R. Bean, O. K. Chung, M. R. Tuinstra, Jeffrey F. Pedersen, J. Erpelding

Department of Agronomy and Horticulture: Faculty Publications

The single kernel characterization system (SKCS) has been widely used in the wheat industry, and SKCS parameters have been linked to end-use quality in wheat. The SKCS has promise as a tool for evaluating sorghum grain quality. However, the SKCS was designed to analyze wheat, which has a different kernel structure from sorghum. To gain a better understanding of the meaning of SKCS predictions for grain sorghum, individual sorghum grains were measured for length, width, thickness (diameter), and weight by laboratory methods and by the SKCS. SKCS predictions for kernel weight and thickness were highly correlated to laboratory measurements. However, …

Lakota Struggles For Cultural Survival: History, Health, And Reservation Life, Benjamin Jewell

Nebraska Anthropologist

The effects of alcohol use on Pine Ridge are epidemic and have had a devastating impact on the current status of the residents. The historic effect of u.s. colonial relations with the Lakota has engendered a system of dependency, making the transition from an independent trading economy to capitalism difficult. This paper is an attempt to investigate the current life of Pine Ridge residents and relate how the past has shaped the present through a successful attempt by the u.s. to bring an end to the life-ways of the Lakota. This analysis will include a detailed statement of the economic …

Conceptions Of Humor: Lakota (Sioux), Koestlerian, And Computational, Benjamin Grant Purzycki

Nebraska Anthropologist

The Lakota (Sioux) sacred clowns (heyoka) of traditional religious practice offer a glimpse of the clown phenomenon found in many of the world's indigenous traditions. By illustrating the unified Lakota and Western conceptions of humor, the logic of how particular entities of the natural environment are understood as relatives according to Lakota thought is brought to light in hopes of introducing the idea that such insights were not only statements or observations about the external, physical world, but also about the internal or mental world.
