Evaluation Of 0 Or 300 Mg Of Optaflexx® On Growth Performance And Carcass Characteristics Of Steers Fed To Different Degrees Of Finish, Robert M. Jones, Curtis J. Bittner, F. Henry Hilscher Hilscher, Mallorie F. Wilken, Galen E. Erickson

Nebraska Beef Cattle Reports

A feedlot study evaluated the effects of ractopamine hydrochloride (Optaflexx®) dosage (0 or 300 mg/steer daily) and days on feed (118, 139, 160, 174 DOF) as a 2 × 3 + 1 factorial (steers fed 174 d were not fed Optaflexx) on performance of big yearlings. No interaction was observed between Optaflexx and days on feed. Feeding Optaflexx improved live final BW, carcass- adjusted ADG, carcass- adjusted feed conversion, and calculated yield grade. Increasing days on feed linearly increased live final BW, carcass-adjusted feed conversion, HCW, dressing percent, and marbling score but not ADG. Furthermore, a quadratic increase in LM …

Corn Residue Quality Throughout The Grazing Season, Shelby E. Gardine, Gavin L. Harsh, Robert G. Bondurant Bondurant, Jana L. Gramkow, Andrea K. Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Changes in in vitro organic matter digestibility and digestible organic matter of corn residue were evaluated throughout the fall grazing and spring grazing seasons. In vitro organic matter digestibility and digestible organic matter were greatest at the beginning of fall grazing and declined over time. Slight weathering resulted in lower quality corn residue available at the beginning of spring grazing compared to the beginning of fall grazing. The in vitro organic matter digestibility of available residue declined 21% over the fall grazing season and 51% throughout the spring grazing season. As the availability of nutrients declines over time, adjustments in …

Nebraska Beef Cattle Reports

A survey was conducted to explore factors influencing corn residue grazing recommendations by crop consultants and producer practices in Nebraska. Approximately 80% of consultants recommended grazing corn residue, while 63% of producers allowed grazing. Of producers who did not graze, about 50% cited concerns related to soil compaction, inconvenience (lack of water, fencing, and land/equipment damage), and lack of access to livestock. Producers who allowed and consultants who recommended grazing were more likely to perceive that grazing residue increased subsequent grain yields. Most consultants (56.0%) and producers (43.8%) reported making decisions in regards to grazing based on their own observation. …

Statistics Used In The Nebraska Beef Report And Their Purpose Jan 2017

Statistics Used In The Nebraska Beef Report And Their Purpose

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore he/ she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description …

Effect Of Heifer Development System On Reproduction And Subsequent Gain As A Pregnant Heifer, Shelby A. Springman, Hazy Rae Nielson, Tonya L. Meyer, Mike Kirby, Jim Teichert, Richard N. Funston Jan 2017

Effect Of Heifer Development System On Reproduction And Subsequent Gain As A Pregnant Heifer, Shelby A. Springman, Hazy Rae Nielson, Tonya L. Meyer, Mike Kirby, Jim Teichert, Richard N. Funston

Nebraska Beef Cattle Reports

Weaned heifers grazed corn residue, upland range, or were fed 1 of 2 drylot diets differing in energy. Heifer development diets did not impact their resulting AI or final pregnancy rates. Cost per pregnant heifer was similar among treatments. A subset of AI- pregnant heifers was placed in a Calan Broadbent individual feeding system during late gestation. As a pregnant heifer, feed efficiency was not impacted by development system. These results indicate producers may utilize their most readily available and/or cost- effective feed resources with no detriment to pregnancy rates or feed efficiency as first- calf heifers.

A First Look At The Microbial Community Of Rabidosa Rabida, A Wolf Spider In Searcy, Arkansas, Patricia Rivera, Ryan Stork, Amber Hug

Journal of the Arkansas Academy of Science

Many diverse animal models have been used to explore the interactions between host organisms and their microbiota. Increased understanding of microbe-host interactions could lead to improved healthcare and drug development. Spiders have venom, digestive fluid, and body fluid components that have been suggested to possess antimicrobial properties that could lead to new and interesting host-microbe interactions. While studies have been published on interactions between bacteria affecting the immune function and behavior of spiders, the spider microbiome has not been established to date. Excreta and body swabs were collected from Rabidosa rabida, a wolf spider typically found on tall grass …

Simulating Foodborne Pathogens In Poultry Production And Processing To Defend Against Intentional Contamination, S. Lankford, D. R. Thompson, S. C. Ricke Jan 2017

Simulating Foodborne Pathogens In Poultry Production And Processing To Defend Against Intentional Contamination, S. Lankford, D. R. Thompson, S. C. Ricke

Journal of the Arkansas Academy of Science

There is a lack of data in recent history of food terrorism attacks, and as such, it is difficult to predict its impact. The food supply industry is one of the most vulnerable industries for terrorist threats while the poultry industry is one of the largest food industries in the United States. A small food terrorism attack against a single poultry processing center has the potential to affect a much larger human population than its immediate consumers. In this work, the spread of foodborne pathogens is simulated in a poultry production and processing system to defend against intentional contamination. An …

Bat Occupancy Estimates And Species Richness At Cache River National Wildlife Refuge, Samuel Schratz, Virginie Rolland, Jason Phillips, Richard Crossett, David Richardson, Thomas S. Risch

Journal of the Arkansas Academy of Science

Six bat species of special concern, threatened or endangered, may occur in one of Arkansas’ largest bottomland hardwood forests, the Cache River National Wildlife Refuge (CRNWR). However, inventory of bat species throughout the refuge has been lacking and management plans may not be adequate in promoting bat conservation. The objectives of this study were to inventory bat species in the CRNWR, and determine bat-habitat associations via occupancy estimates. From May–August 2014 and 2015, we mist-netted from sunset for 5 hours. We also deployed bioacoustic devices throughout 5 habitat types (cypress-tupelo [dominantly Taxodium distichum and Nyssa aquatica], emergent wetland, mature …

The Social Behavior Of Rehabilitated Spider Monkeys (Ateles Geoffroyi), Anthony Denice Jan 2017

The Social Behavior Of Rehabilitated Spider Monkeys (Ateles Geoffroyi), Anthony Denice

All Master's Theses

The welfare of captive primates in laboratories, sanctuaries, and zoos is affected by various aspects of their environments. Although space restrictions increase aggression and stress-related behaviors in most captive animals, primates show diverse mechanisms for displacing stress and mitigating conflict. Many primates, including wild spider monkeys (genus Ateles), use these mechanisms flexibly to cope with social and environmental stressors. I investigated whether or not captive black-handed spider monkeys (Ateles geoffroyi) use behavioral strategies to cope with potential stressors in captivity. In particular, I tested whether an affiliative or avoidant strategy was used in response to changes in …

Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers Jan 2017

Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers

All Master's Theses

Elk (Cervus elaphus) are generalist herbivores, exploiting a variety of environments. I studied habitat selection and sexual segregation of the Colockum elk herd in central Washington. I used a resource selection probability function (RSPF) to evaluate habitat use by males and females during summer and winter seasons. I assisted Washington State Department of Fish and Wildlife (WDFW) in capturing and placing GPS collars on males, and used an existing GPS dataset from females to investigate the extent to which sexual segregation was occurring in the Colockum herd. During summer, males selected steep slopes on north, west and south …

Salmonids In An Urban Stream: Movement, Habitat, And Potential Barriers, Connor Thomas Parrish Jan 2017

Salmonids In An Urban Stream: Movement, Habitat, And Potential Barriers, Connor Thomas Parrish

All Master's Theses

Studies on the movement of salmonids in the Pacific Northwest have been vital to their management and recovery. Salmonids can move great distances in search of food, habitat and potential mates, requiring them to travel through a range of different habitat types. Altered and degraded streams may restrict native salmonid use and access to habitat within or beyond urban areas. Locally, restoring native salmonids to streams in urbanized areas is of interest to recovery efforts. However, there is a lack of information in the literature on how salmonids use and navigate urbanized streams. This study used Passive Integrated Transponders (PIT-tags) …

Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald Jan 2017

Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald

All Master's Theses

Captive chimpanzees (Pan troglodytes) engage with enrichment objects extensively during the daytime, yet relatively little is known regarding their use of available enrichment at night. This study examined night-time enrichment use in three adult chimpanzees at the Chimpanzee and Human Communication Institute. Every evening, the chimpanzees received a variety of enrichment objects. The objects belonged to one of nine categories. Night-vision video cameras recorded the chimpanzees’ night-time behaviors every Monday through Thursday from July 9 to August 9, 2012 (Carner et al., 2013). The present study used a focal animal, instantaneous sampling method (Martin & Bateson, 2007) to …

Enrichment Use & Social Interactions In A Mixed-Species Enclosure Of Sumatran (Pongo Abelij) & Bornean Orangutans (P. Pygmaeus) & Northern White-Cheeked Gibbons (Nomascus Leucogenys), Emily Veitia

All Master's Theses

Enrichment is an aspect of captive husbandry that has been shown to positively impact animals’ well-being and can be designed to encourage species-typical behaviors, such as foraging and arboreality. Enrichment can include housing together multiple compatible species. Orangutans are sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two Sumatran (Pongo abelii) and two Bornean (P. pygmaeus) orangutans with …
