Replacing Fertilizer Nitrogen With Dried Distillers Grains Supplement To Yearling Steers Grazing Bromegrass Pastures: Economics And Modeling, Matthew A. Greenquist, Terry J. Klopfenstein, Walter H. Schacht, Galen E. Erickson Jan 2009

Replacing Fertilizer Nitrogen With Dried Distillers Grains Supplement To Yearling Steers Grazing Bromegrass Pastures: Economics And Modeling, Matthew A. Greenquist, Terry J. Klopfenstein, Walter H. Schacht, Galen E. Erickson

Nebraska Beef Cattle Reports

An economic analysis of a three-year study evaluated use of N fertilizer and dried distillers grains plus solubles (DDGS) supplementation to yearling steers grazing smooth bromegrass in eastern Nebraska (Nebraska Beef Report, 2009, pp. 26-28). Costs of gain tended to be lower for cattle on fertilized pastures. Grazing profitability was lowest for cattle on non-fertilized pastures, intermediate for cattle supplemented with DDGS, and highest for cattle on fertilized pastures. The weight advantage (9%) of steers supplemented with DDGS during the grazing period was maintained through the finishing period, leading to greater profitability. Profitability for steers supplemented with DDGS at the …

Cattle Performance And Economic Analysis Of Diets Containing Wet Distillers Grains And Dry-Rolled Or Steam-Flaked Corn, Corineah Godsey, William Griffin, Matt K. Luebbe, Joshua R. Benton, Galen E. Erickson, Terry J. Klopfenstein Jan 2009

Cattle Performance And Economic Analysis Of Diets Containing Wet Distillers Grains And Dry-Rolled Or Steam-Flaked Corn, Corineah Godsey, William Griffin, Matt K. Luebbe, Joshua R. Benton, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A finishing study was conducted to determine the effect of utilizing dry-rolled (DRC) or steam-flaked (SFC) corn in diets containing wet distillers grains without solubles (WDG). An interaction between corn processing method and DG level was observed for average daily gain (ADG) and feed-gain ratio (F:G), but not for dry matter intake (DMI). In diets containing DRC, ADG increased quadratically (P = 0.02) as WDG level increased, but no difference was observed in gain when steers were fed SFC diets with increasing level of WDG. Feed efficiency responded quadratically for diets containing DRC, with an optimum WDG inclusion of 20% …

Effects Of Surface Soil Temperature On Daily Water Intake In Feedlot Cattle, Rodrigo Arias, Terry L. Mader Jan 2009

Effects Of Surface Soil Temperature On Daily Water Intake In Feedlot Cattle, Rodrigo Arias, Terry L. Mader

Nebraska Beef Cattle Reports

The relationships among soil surface temperature (SST), soil temperature (ST) (4 inches depth) and daily water intake (DWI) were studied using data collected between 2004 and 2006. The equations obtained through simple and polynomial linear regression were evalu¬ated using data collected during the summer 2007. An overall model (May-October) and a summer model (June-August) were developed. The best fit was reached with the overall model using SST in a quadratic model (r2 = 0.86), whereas the summer model fit linearly with SST (r2 = 0.70). Both models tend¬ed to slightly over-predict DWI (13.5% and 12.5%, respectively).

Effects Of Sorting Cattle By Weight And Time Of Year On Finishing Performance, Carcass Characteristics And Economics, Daniel R. Adams, Matt K. Luebbe, William Griffin, Terry J. Klopfenstein, Galen E. Erickson Jan 2009

Effects Of Sorting Cattle By Weight And Time Of Year On Finishing Performance, Carcass Characteristics And Economics, Daniel R. Adams, Matt K. Luebbe, William Griffin, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Sorting steers for three different finishing systems (calf-feds, summer yearlings and fall yearlings) resulted in no differences in performance or average carcass characteristics compared to unsorted steers. Sorting decreased variation in hot carcass weight and number of carcasses over 950 lb. Sorting did not increase profit when calf-feds or fall yearlings were sold live compared to unsorted calf-feds and fall yearlings. However, when sold on a grid basis, sorting did increase profit for summer and fall yearlings.

Level Of Wet Distillers Grains Plus Solubles And Solubles Ensiled With Wheat Straw For Growing Steers, Megan Peterson, Matt K. Luebbe, Richard J. Rasby, Terry J. Klopfenstein, Galen E. Erickson, Luke Kovarik Jan 2009

Level Of Wet Distillers Grains Plus Solubles And Solubles Ensiled With Wheat Straw For Growing Steers, Megan Peterson, Matt K. Luebbe, Richard J. Rasby, Terry J. Klopfenstein, Galen E. Erickson, Luke Kovarik

Nebraska Beef Cattle Reports

A growing study compared wet distillers grains plus solubles (WDGS) and solubles ensiled with wheat straw individually fed to crossbred steers. Four blends of ensiled distillers grain and solubles were used to compare performance on growing calves versus feeding ensiled byproducts alone. Increasing the level of distillers grains in the diet increased average daily gain (ADG) and dry matter intake (DMI). The nonensiled distillers grain treatments had at least equal ADG and feed-to-gain ratio (F:G) compared to the ensiled treatments.

Effect Of Dietary Cation-Anion Difference On Feedlot Performance, Nitrogen Mass Balance And Manure Ph In Open Feedlot Pens, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Joshua R. Benton Jan 2009

Effect Of Dietary Cation-Anion Difference On Feedlot Performance, Nitrogen Mass Balance And Manure Ph In Open Feedlot Pens, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Joshua R. Benton

Nebraska Beef Cattle Reports

Two experiments were conducted to evaluate the effect of dietary cation-anion difference (DCAD) at two levels (-16 and +20 mEq) on feedlot performance and nutrient mass balance in open feedlots. Decreasing DCAD did not negatively impact cattle performance or carcass characteristics. Feeding negative DCAD diets resulted in lower manure pH in both the winter and summer experiments. Final soil core pH was reduced only in the winter experiment. Percentage of N lost was not influenced by DCAD in either experiment. The decrease in manure pH is likely not enough to reduce the amount of N lost in open feedlot pens.

Effect Of Estrus Synchronization With A Single Injection Of Prostaglandin During Natural Service Mating, Daniel Larson, Jacqueline A. Musgrave, Richard N. Funston Jan 2009

Effect Of Estrus Synchronization With A Single Injection Of Prostaglandin During Natural Service Mating, Daniel Larson, Jacqueline A. Musgrave, Richard N. Funston

Nebraska Beef Cattle Reports

Records from unsynchronized cows (n = 2073; 60-day breeding season) were compared with records from synchronized cows (n = 517; 45-day breeding season) collected between 2000 and 2006. A single injection of prostaglandin F2α was administered approximately 108 hours after bull turn-in to synchronize estrus in spring calving mature beef cows. Estrus synchronization increased the percentage of cows calving in the first 21 days without affecting pregnancy rates. However, weaning BW of calves was not significantly different. Estrus synchronization improves synchrony of calving in a shorter breeding season with similar overall pregnancy rates.

The Effects On Ruminal Ph, Feed Intake And Digestibility When Using Wet Corn Gluten Feed To Adapt Cattle To Finishing Diets, Taia Huls, Nathan Meyer, Galen E. Erickson, Terry J. Klopfenstein, Rick Stock Jan 2009

The Effects On Ruminal Ph, Feed Intake And Digestibility When Using Wet Corn Gluten Feed To Adapt Cattle To Finishing Diets, Taia Huls, Nathan Meyer, Galen E. Erickson, Terry J. Klopfenstein, Rick Stock

Nebraska Beef Cattle Reports

A 33-day grain adaptation trial was conducted comparing wet corn gluten feed (WCGF; Sweet Bran®, Cargill) fed at decreasing levels (87.5% to 35%) to a traditional grain adaptation with decreasing forage (45% to 7.5%; CON) to test the effects on ruminal pH, dry matter intake (DMI) and in situ DM digestibility. Steers adapted by decreasing WCGF had greater DMI than CON (P < 0.01). During adaptation, DMI increased and ruminal pH decreased across both treatments. Steers adapted using WCGF had greater in situ DM digestion than steers adapted using CON. Diets containing WCGF had greater DM digestibility than diets containing forage, whether incubated in either CON or WCGF fed steers. Decreasing WCGF inclusion instead of forage is a viable method for adapting feedlot cattle to high-concentrate diets.

Sulfur In Distillers Grains, Sarah Vanness, Terry J. Klopfenstein, Galen E. Erickson, Kip Karges Jan 2009

Sulfur In Distillers Grains, Sarah Vanness, Terry J. Klopfenstein, Galen E. Erickson, Kip Karges

Nebraska Beef Cattle Reports

Data were compiled from 4,143 cattle on byproduct feeding experiments. Incidence of polioencephalomalacia was small (0.14%) in diets containing 0.46% or less sulfur (S). Incidences of polioencephalomalacia increased when cattle were fed diets above 0.46% S and especially above 0.56%. Phosphoric acid successfully replaced sulfuric acid in ethanol fermentation, but the amount and cost of phosphoric acid likely limit the economic feasibility of its use.

Profit Variability For Calf-Fed And Yearling Production Systems, Rebecca Small, Darrell R. Mark, Dillon Feuz, Terry J. Klopfenstein, William Griffin, Daniel R. Adams Jan 2009

Profit Variability For Calf-Fed And Yearling Production Systems, Rebecca Small, Darrell R. Mark, Dillon Feuz, Terry J. Klopfenstein, William Griffin, Daniel R. Adams

Nebraska Beef Cattle Reports

Profitability of calf-fed and backgrounding yearling systems was determined based on actual production data and prices from 1996 to 2007, and variability across years was compared. The two systems exhibited similar profits, on average, but the calf-fed system showed less profit variability, suggesting there is more risk inherent in a yearling backgrounding and finishing system. Also, profitable years were more apt to have less variable corn prices.

S. Barnett, H. C. Martin, J. H. Seagraves, M. W. Matthews, R. Winterringer, C. Osborne, Alan D. Christian, N. J. Wentz

Journal of the Arkansas Academy of Science

We analyzed stream inventories, phylogeographic studies, community and population estimates, life history and reproductive biology research, and suitable habitat investigations conducted from 1997-2008, as well as the Arkansas Natural Heritage Commission mussel database, to update the conservation status for all native freshwater unionoid bivalves thought to occur in Arkansas. Prior to this study, Harris et al. (1997) reviewed the distribution and status of 75 freshwater mussels considered native to Arkansas and ranked 22 species as endangered, threatened or special concern. We now recognize 85 mussel taxa in Arkansas; however, some of those have yet to be described or their nomenclature …

Role Of Near-Miss Bird Strikes In Assessing Hazards, Matt W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Beiger Jan 2009

Role Of Near-Miss Bird Strikes In Assessing Hazards, Matt W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Beiger

Human–Wildlife Interactions

Management of problem wildlife within the airfield environment is a difficult job. Today’s Bird–Animal Aircraft Strike Hazard (BASH) program managers require as much information as possible to accomplish their tasks. Bird censuses and actual bird-strike events in and around the air operations area are used to make airfield management decisions and to assess the risk of bird hazards to aircraft. Both types of information are sampled rather sparsely. Avian radar is now being used as a new tool to provide continuous sampling of bird activity that significantly supplements visual censuses. The measure of risk used today is commonly expressed as …

Personal And Corporate Liability In The Aftermath Of Bird Strikes: A Costly Consideration, Larry A. Dale Jan 2009

Personal And Corporate Liability In The Aftermath Of Bird Strikes: A Costly Consideration, Larry A. Dale

Human–Wildlife Interactions

This paper details liability issues inherent in bird–aircraft collisions (bird-strike) incidents at airports and discusses how airport managers and operators must strive to conduct accurate assessments and develop and implement an effective wildlife management plan. Such efforts are mandated by Federal Aviation Administration (FAA) regulations, and failure to follow them may result in loss of human life and property, as well as large financial penalties for managers and operators and adverse media attention and public criticism for the airport authority.

Using Wedelia As Ground Cover On Tropical Airports To Reduce Bird Activity, Michael A. Linnell, Michael R. Conover, Tim J. Ohashi Jan 2009

Using Wedelia As Ground Cover On Tropical Airports To Reduce Bird Activity, Michael A. Linnell, Michael R. Conover, Tim J. Ohashi

Human–Wildlife Interactions

Bird–aircraft collisions (i.e., bird strikes) are a major problem at airports worldwide, often because birds are attracted to airfields to feed on seeds, insects, or rodents that abound in the grassy areas near runways and taxiways. We compared an alternative ground cover, wedelia (Wedelia trilobata), to existing vegetation (control plots) on the airfield at Lihue Airport, Kauai, Hawaii, to determine if bird populations on the airport could be reduced by eliminating their forage base. We studied wedalia because it is a low-growing plant that did not need mowing, was easily established in plots, and out-competed other plants, resulting …

Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender Jan 2009

Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender

Human–Wildlife Interactions

Historically, Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability of RMNP’s bear population or could increase the potential for human–bear conflict. Therefore, we investigated contemporary survival and productivity parameters for RMNP’s black bear population from 2003 to 2006 and compared these values to historic levels (1984–1991) and population means throughout the western United States to clarify the current status of RMNP’s bear population. The contemporary black bear population showed signs …

Coexisting With Cougars: Public Perceptions, Attitudes, And Awareness Of Cougars On The Urban-Rural Fringe Of Calgary, Alberta, Canada, Clarisse Thornton, Michael S. Quinn

Human–Wildlife Interactions

Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population. We determined the attitudes, knowledge, and perceptions toward cougars by residents in the urban-rural fringe of Calgary, Alberta, Canada, an area populated by both cougars and humans. We sent a survey to a stratified, random sample of 1,508 residents. Survey analysis included a potential for conflict index (PCI) to help provide quantitative direction for future cougar management. We analyzed and tested for differences among 7 variables: livestock …

Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser Jan 2009

Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser

Human–Wildlife Interactions

Canada geese (Branta canadensis) often cause significant damage when they strike aircraft. They are responsible for a reported minimum of $2.6 million in damage per year to civil aviation in the United States. Knowledge of goose movements in relation to airports would allow wildlife managers to allocate time and funds to manage those populations that pose the greatest threat to aircraft. We placed alpha-numeric neck collars on 300 Canada geese within 8 km of both John F. Kennedy International Airport (JFKIA) and LaGuardia Airport in New York, New York. We conducted weekly observations for 2 years within a …

The Effects Of Feeding Level And Stocking Density On The Growth And Feed Efficiency Of Himri Barbel Fry, Barbus Luteus (Heckel, 1843), Kaya Gökçek, Yalçin Tepe Jan 2009

The Effects Of Feeding Level And Stocking Density On The Growth And Feed Efficiency Of Himri Barbel Fry, Barbus Luteus (Heckel, 1843), Kaya Gökçek, Yalçin Tepe

Turkish Journal of Veterinary & Animal Sciences

Two stocking densities (20 and 40 fry/80-l tank) with 4 feeding rates (2.5%, 5.0%, 7.5%, and 10.0% body weight/day) were used to determine the optimum feeding level for himri barbel fry during a 60-day culture period. Water quality parameters (temperature, dissolved oxygen, pH, and total ammonia nitrogen) were monitored during the experiment. Final body weight and specific growth rate (SGR) was significantly lower with the 2.5% feeding rate than with the others, at both stocking densities; however, no significant differences were observed between the other feeding rates and between stocking densities. The best feed conversion ratio (FCR) of 1.37 was …

The Relationship Between Morphometric And Long Bone Measurements Of The Morkaraman Sheep, Hasan Alpak, Vedat Onar, Rifat Mutuş Jan 2009

The Relationship Between Morphometric And Long Bone Measurements Of The Morkaraman Sheep, Hasan Alpak, Vedat Onar, Rifat Mutuş

Turkish Journal of Veterinary & Animal Sciences

In this study, a total of 40 adult female Morkaraman sheep, a local Turkish breed, were used. After taking their body measurements and carcass weights, the meat was cut off the bones; the skeletal bones were then removed, macerated and every long bone weighed. Thereafter, morphometric measurements of the long bones were taken. The coefficients obtained from the correlation of osteometric measurements and morphological data were in general low (r < 0.600), though certain relationships were found to be significant. Regression of morphological variables on osteometric measurements was statistically significant. By this, regression formulas were obtained which can contribute to predict the visible morphology in zooarchaeological studies. Length measurements would be more suitable for predicting shoulder height than using width measurements of the long bone. On the other hand, body and carcass weights and chest circle would be determined more efficiently by measuring the width of long bones (Bp, Bd, SD). Furthermore, the humero-femoral index formula can be used to identify sheep in an archaeological bone collection of several animals.

Seasonal Changes In Condition, Hepatosomatic Index And Parasitism In Sterlet (Acipenser Ruthenus L.), Mirjana Lenhardt, Ivan Jaric, Predrag Cakic, Gorcin Cvijanovic, Zoran Gacic, Jelena Kolarevic

Turkish Journal of Veterinary & Animal Sciences

Measurements of biomarker responses in fish from contaminated sites could provide valuable data for environmental risk assessment. Biomarkers are sensitive to both environmental pollution and confounding factors that are not related to pollution (e.g., season, nutritional status, and population density). Unfortunately, data about the latter group are scarce. Therefore, juvenile sterlet (Acipenser ruthenus L.) specimens were collected on a monthly basis from the Danube River from September 2002 through August 2003 to determine if seasonal changes exist in condition, hepatosomatic index, and parasitism. Fulton condition factor (FCF range: 0.27 - 0.79), hepatosomatic index (HSI range: 1.14 - 6.67) and Skrjabinopsolus …
