Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska has an abundance of crop residue available for late fall and winter grazing. However, several factors prevent the grazing of many fields, including the location of fields in relation to the cattle, the lack of shelter or appropriate fencing and water availability. Despite these limitations, residue grazing is an important resource to many cattle operations, primarily as either a winter feed resource for maintaining the breeding herd or putting weight on cull cows. Calves weaned in the fall can also be wintered on cornstalks if appropriate supplementation is used.

Tracing The History Of Blackbird Research Through An Industry's Looking Glass: The Sunflower Magazine, George M. Linz, H. Jeffrey Homan

Vertebrate Pest Conference Proceedings: 18th (1998)

The Sunflower magazine, the voice of the National Sunflower Organization, featured articles in January 1978 and December 1996 that began with these words, "If Old King Cole was a merry old soul, it was probably because he had only four and twenty blackbirds to contend with, and they were all out of commission!" This quotation captures the sentiments of sunflower growers, who have identified blackbirds as a major production problem since the 1960s. The National (formerly Denver) Wildlife Research Center, a unit within the U.S. Department of Agriculture's Animal and Plant Health Inspection Service Wildlife Services, is charged with both …

Pen Space Allocations And Pelleting Of Swine Diets, Mike Brumm

Nebraska Swine Reports

An experiment was conducted to determine whether an interaction exists between pen space allocation (14 versus 19 pigs per pen in 8 x 14 ft pens) and physical form of the diet (meal versus pellet) in a fully slatted facility. There were no interactions between diet form and pen space allocation for daily gain, feed intake or feed conversion efficiency. Pigs fed pelleted diets had a 2.3 percent improvement in daily gain and a 7.9 percent improvement in feed efficiency. Although pigs housed 14-per-pen grew faster than those housed 19-per-pen with no difference in feed conversion efficiency, pigs in the …

Light-Test Weight Corn For Growing And Finishing Steers, B. A. Weichenthal, Ivan G. Rush, B. G. Van Pelt

Panhandle Research and Extension Center

Light-test weight corn (59.2 to 61.5 kg/hL; 46 to 48 lb/bu) was compared to normal corn (72 kg/hL; 56 lb/bu) in growing and finishing diets for largeframe crossbred steer calves in 2 consecutive yr. The source of the calves was the same each year as was the diet composition. Growing diet dry matter included 32.9% corn silage, 22.3% alfalfa haylage, 37% dry rolled corn, and 7.8% protein supplement. Finishing diet dry matter included 9.2% corn silage, 86.2% dry rolled corn, and 4.6% protein supplement. Rumensin was included in both diets and steers were implanted with Synovex Sâ at the start …

Porcupine Damage And Repellent Research In The Interior Pacific Northwest, Gary W. Witmer, Michael J. Pipas

Vertebrate Pest Conference Proceedings: 18th (1998)

Porcupines (Erethizon dorsatum) rely on trees and shrubs for winter food and can cause serious, localized damage to conifers. Twenty-two percent of ponderosa trees (Pinus ponderosa) examined in southeastern Washington were damaged by porcupines. Most damage involved complete girdling of the mid- to upper boles of the larger trees (12 to 30 cm dbh) in the stand. Preliminary repellent trials with captive porcupines suggested that several materials might reduce tree damage, especially predator-associated odors. Field trials are needed to assess efficacy and duration of protection under ambient winter conditions.

Rat Management For Endangered Species Protection In The U.S. Virgin Islands, Gary W. Witmer, Earl W. Campbell Iii, Frank Boyd

Vertebrate Pest Conference Proceedings: 18th (1998)

Introduced roof rats (Rartus rattus) pose a substantial threat to the fauna and flora of many tropical islands. In the Caribbean, there is concern about rat impacts to several endangered species, including the Atlantic hawksbill sea turtle (Eretmochelys imbricata) and the least tern (Sterna antillarum). The authors surveyed the rat population on Buck Island, Buck Island Reef National Monument, U .S. Virgin Islands in February 1998. Based on three nights of trapping, rats were of low to moderate abundance during the sampling period when compared to results from other Caribbean islands. The impact of …

The Impact Of Timber Management On The Phytochemicals Associated With Black Bear Damage, Dale L. Nolte, Bruce A. Kimball, Georg J. Ziegltrum

Vertebrate Pest Conference Proceedings: 18th (1998)

Black bears forage on Douglas-fir vascular tissue in the spring, and this behavior can be severely detrimental to the health and economic value of a timber stand. Foraging is selective in that not all stands are damaged and, within a stand, one tree may be stripped while its neighbor is ignored or minimally sampled. A series of studies was conducted to assess whether bear selectivity is affected by chemical constituents within vascular tissue, and whether these constituents are affected by silvicultural practices. The results are interpreted to identify forest practices that may alleviate damage, or at least predict where damage …

Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann

Vertebrate Pest Conference Proceedings: 18th (1998)

A two-choice, taste preference study was conducted using 18 northern pocket gophers to evaluate pelleted sorghum, granulated sorghum, and wax block baits containing either 0.01 to 0.05 % quinine or 0.10 to 5.0 % sucrose. Bait consumption was significantly higher across treatments (P≤.001) for granulated sorghum, followed by pelleted sorghum, and wax blocks. Gophers also showed a high frequency of moving the granulated bait in their cheek pouches to be deposited at alternate locations within their cages. Although increasing sucrose concentration did not produce significantly (P ≥.10) enhanced consumption for any of the baits, a trend toward increasing preference with …

Effects Of Extruded Corn Or Grain Sorghum On Intake, Digestibility, Weight Gain, And Carcasses Of Finishing Steers, R. J. Gaebe, D. W. Sanson, Ivan G. Rush, M. L. Riley, D. L. Hixon, S. I. Paisley

Panhandle Research and Extension Center

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets were fed for 110 d and contained 78.6% of the respective grain, 9% alfalfa pellets, 8.2% molasses, and 4.2% protein-mineral supplement. Daily gain was highest (P < .049) for steers fed RC, and the ADG of steers fed RGS was higher than that of steers fed extruded diets; there was no difference in ADG between steers fed EC and those fed EGS. Steers fed dry-rolled diets consumed more DM (P = .001) than steers fed extruded diets. Feed efficiency …

G98-1373 Escherichica Coli Testing For Process Control Verification — Pork Carcass Sampling, Mindy Brashears, Dianne Peters

University of Nebraska-Lincoln Extension: Historical Materials

In July 1996, the USDA published the Final Rule on Pathogen Reduction for meat and poultry processing facilities. Its goal is to reduce the occurrence of food-borne pathogens in meat and poultry products. The rule requires carcass sampling for "generic" E. coli in meat and poultry slaughter operations. The USDA has developed guidelines for acceptable, marginal and unacceptable amounts of E. coli to be used by the processor to determine if their process is controlling microbial hazards. If E. coli testing indicates that the process is not in control of the microbial hazards, then the processors may have to make …

Consequences Of Differing Wool Growth Rates On Staple Strength Of Merino Wethers With Divergent Staple Strengths, A. C. Schlink, G. Mata, R. M. Lewis

Department of Animal Science: Faculty Publications

An experiment was conducted to determine the effects of dietary protein intake after a period of weight loss on the wool components of staple strength for sheep with a history of low or high staple strength (18.0 vs 34 Nlktex). After being fed to lose 15% of their liveweight over 10 weeks, sheep within each staple strength group were assigned in equal numbers to either a low or high protein diet designed to re-gain initialliveweight in 8 weeks. Liveweight, feed intakes and the growth, fibre diameter and fibre length characteristics of wool were measured at regular intervals. After the weight …

Effect Of Winter Gain On Summer Rate Of Gain And Finishing Performance Of Yearling Steers, Dale Downs, Galen E. Erickson, Don C. Adams, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The effect of winter rate of gain on subsequent grazing and finishing performance was evaluated using 80 medium- framed steers. During the winter period, steers were fed to achieve gains of approximately .7 (low gain; 40 head) or 1.7 lb/day (high gain; 40 head). Warm-season Sandhills range was grazed by 20 low-gain and 20 high-gain steers, while the other 40 grazed bromegrass pasture from May to September. Both low- and high-gain cattle grazing brome pasture gained slower than those grazing sandhills range. During summer grazing, low-gain cattle gained faster than high-gain cattle, but compensated for only 19.9% (sandhills) and 18.7% …

Feather Meal As A Source Of Sulfur Amino Acids For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

One-hundred twenty individually fed steer calves were used to evaluate feather meal as a source of sulfur amino acids. Treatment proteins included a urea control and meat and bone meal (6.4% of dietary DM) plus 0, 1, or 2% feather meal with incremental levels of rumen protected methionine. Adding feather meal to meat and bone meal resulted in a linear increase in gain. Likewise, rumen-protected methionine also improved gain. These results indicate feather meal can provide a portion of the sulfur amino acids lacking in meat and bone meal. However, additional methionine may further improve performance.

Use Of The Nrc Model For Evaluating Nutrient Balances Of Grazing Beef Cattle, Greg Lardy, Don C. Adams, Terry J. Klopfenstein, Dennis R. Brink

Nebraska Beef Cattle Reports

Research conducted at the Gudmundsen Sandhills Laboratory evaluated the National Research Council Beef Cattle Nutrient Requirements Model. Equations describing seasonal variability in CP, IVOMD, escape protein and degradable intake protein of native Sandhills range and subirrigated meadow were developed. Estimates of TDN and protein degradability for feedstuffs commonly used by Nebraska cow-calf producers are given. The NRC Model generally predicted nutrient balances in agreement with research trials. Microbial efficiency is lower for less-digestible forages. The NRC model is useful for evaluating grazed diets when accurate estimates of protein degradability, digestibility and intake are available.

Summer And Fall Forage Grazing Combinations: Five-Year Summary, Drew Shain, Terry J. Klopfenstein, D. J. Jordon, Rick Stock

Nebraska Beef Cattle Reports

A five-year study using British-breed crossbred cattle included slaughter breakeven analysis and evaluated the effect of grazing alternative summer and fall forages on beef production systems. Grazed summer and fall forage combinations included continuous brome and combinations of brome, warm-season grasses, alfalfa, sudangrass, red clover, native Sandhills range, turnips, rye and cornstalks. The most consistent improvement in summer grazing gain and most desirable slaughter breakeven costs were observed in cattle grazing brome and warm-season grasses or brome and Sandhills range. A reduction in slaughter breakeven cost by grazing fall forages was observed in years with adequate moisture for forage growth. …

Holistic Faculty Development: Supporting Personal, Professional, And Organizational Well-Being, Glenda T. Hubbard, Sally S. Atkins, Kathleen T. Brinko

To Improve the Academy: A Journal of Educational Development

In recent years, higher education has begun to realize the great influence that faculty quality of life has on student learning and on overall institutional effectiveness. This article examines the interactive effect of personal, professional, and organizational well-being and describes a center that integrates four kinds of services-faculty development, employee assistance, health promotion, and organizational development-that work both separately and collaboratively. The result is a synergistic organization that is able to tackle complex institutional problems that could not be addressed by any one program alone.

A Frailty Model For Projection Of Human Mortality Improvements, Shaun S. Wang, Robert L. Brown

Journal of Actuarial Practice (1993–2006)

Based on the everyday observations that individual human beings vary significantly in their capacity to combat death, we adopt a so-called frailty model of human mortality. This frailty model assumes that each individual in a given population is endowed with his or her own frailty index, r, which remains constant for life. In addition, we assume that the individual's force of mortality (hazard rate function) at age x, Ux(r), satisfies Ux(r) = rUx where Ux is the population's base force of mortality at age x. Given the probability distribution of the frailty index among the newborns in the population, an …

Statistical Design And Analysis Of Producer/Consumer Evaluations To Assess Plant Quality, Walter W. Stroup, Stacy A. Adams, Ellen Paparozzi

Department of Agronomy and Horticulture: Faculty Publications

Researchers in ornamental horticulture often want to assess the effects of experimental treatments on plant quality. Producers often use the results of such experiments to establish the minimum level of a treatment, for instance, the amount of a growth regulator or a nutrient, such as nitrogen, needed to achieve desired plant quality. For edible plants, quality can be quantified objectively by using numeric response variable such as yield or nutritional content. However, for ornamental plants, quality depends on aesthetic appeal and consumer acceptance, traits which are subjective and qualitative.

Statistical models for the design and analysis of experiments involving numeric …

Effect Of Energy Source And Escape Protein On Receiving And Finishing Performance And Health Of Calves, R. A. Mccoy, Rick Stock, Terry J. Klopfenstein, D. H. Shain, M. J. Klemesrud

Department of Animal Science: Faculty Publications

Two receiving and two finishing trials evaluated energy source and escape protein supplementation for calves. In receiving Trial 1, 398 calves (257 ± 24 kg BW) were used in a 2 x 2 factorial arrangement of treatments. Energy sources were dryrolled corn (DRC) and wet corn gluten feed (WCGF); each was fed without or with supplemental escape protein (EP). Calves fed WCGF gained slower ( P < .05) and consumed less DM ( P < .01) than calves fed DRC. Feed efficiency improved ( P < .10) with EP supplementation. In finishing Trial 1, 240 calves (305 ± 21 kg BW) were used. The arrangement of treatments was the same as in receiving Trial 1. Calves fed DRC/WCGF tended ( P = .15) to be more efficient and consumed less DM ( P < .05) than calves fed DRC. In receiving Trial 2, 315 calves (252 ± 23 kg BW) were fed diets similar to those fed in receiving Trial 1. Calves fed WCGF consumed less DM ( P < .01), gained similarly ( P > .15), and were more efficient ( P < .10) than calves fed DRC. In finishing Trial 2, 320 calves (298 ± 23 kg BW) were fed diets containing DRC, DRC/WCGF, high-moisture corn (HMC), HMC/WCGF, and DRC/HMC; each was fed without or with supplemental EP. An energy source ´ protein supplement interaction was detected for gain ( P < .05) and efficiency ( P < .01). Results suggest that WCGF has a NE_g greater than DRC in receiving diets and a NE_g similar to that of DRC but lower than that of HMC in finishing diets.
