Effect Of Die Retention Time On Pellet Quality And Phytase Stability Of A Corn-Soybean Meal Swine Diet, M. Saensukjaroenphon, C. E. Evans, C. K. Jones, C. H. Fahrenholz, C. B. Paulk, C. R. Stark

Kansas Agricultural Experiment Station Research Reports

Phytase is a phosphohydrolytic enzyme that releases phosphorus from phytate in animal feed. However, pelleting is a thermal process that can denature phytase. It is hypothesized that there are many factors that can account for phytase denaturing during the pelleting process, such as pellet mill model, die length to diameter ratio (L:D), steam quality, and residence time in conditioner and die. Therefore, the objective of this experiment was to determine the effect of pellet mill model, die thickness, and die retention time on pellet quality and phytase stability. Treatments were arranged as a completely randomized design to determine the ...

Tree Squirrels And Fishers In Northern California: The Effects Of Masting Hardwoods On Stand Use, Andria M. Townsend 2019 Humboldt State University

Tree Squirrels And Fishers In Northern California: The Effects Of Masting Hardwoods On Stand Use, Andria M. Townsend

Theses and projects

In western North America, tree squirrels such as western gray (Sciurus griseus) and Douglas squirrels (Tamiasciurus douglasii) are potentially important prey for fishers (Pekania pennanti). Western gray squirrels in particular may be highly ranked due to their large body size. Masting trees including black oak (Quercus kelloggii) and tanoak (Notholithocarpus densiflorus) produce an important food source for tree squirrels; therefore, forest stands containing these trees may be useful to foraging fishers. I hypothesized that; 1) the abundance of western gray and Douglas squirrels in a stand is influenced by the mast production capacity of that stand, and 2) fisher stand ...


Additional Information On A Nonnative Whiptail Population (Aspidoscelis Flagellicauda/Sonorae Complex) In Suburban Orange County, California, Richard A. Erickson, Weston G. Burt 2019 San Diego Natural History Museum

Additional Information On A Nonnative Whiptail Population (Aspidoscelis Flagellicauda/Sonorae Complex) In Suburban Orange County, California, Richard A. Erickson, Weston G. Burt

Bulletin of the Southern California Academy of Sciences

A nonnative population of all-female spotted whiptails from the Asidoscelis flagellicauda/sonorae complex was reported from suburban Irvine, Orange County in 2015 and 2016. We report additional suburban observations dating back to 2010 from Laguna Woods and extending the range south ~6 km southwest to Aliso Viejo. We hope that this and other exotic reptile species will remain restricted to highly altered urban environments and not threaten native species in natural habitats.


Sheep Are Sentient, But Not Identical, Alison Hanlon 2019 University College Dublin

Sheep Are Sentient, But Not Identical, Alison Hanlon

Animal Sentience

Marino & Merskin (M&M) provide a timely reminder that sheep have advanced cognitive abilities, but do we still have to provide evidence to justify animal sentience? In the EU, regulations are designed to support farm animal welfare. Whilst the regulations are imperfect, they do emphasize behavioural needs and other concepts relevant to sentience. The persistence of sheep welfare issues such as lamb mortality indicates that regulations may not be achieving their desired goal. We can quibble about the science described by M&M yet reach the same conclusion: sheep (lambs, ewes and rams) are not all identical, but they are ...

Factors Influencing The Movement Of Livestock Guardian Dogs In The Edwards Plateau Of Texas: Implications For Efficacy, Behavior, And Territoriality, John M. Tomeček, Justin T. French, John W. Walker, Nova J. Silvy, Nicholas A. Bromen

Human–Wildlife Interactions

Livestock guardian dog (Canis lupus familiaris; LGD) breeds of domestic dog worldwide provide a degree of control over predation losses. The application of LGDs as a wildlife damage management tool evolved as a cultural practice in the Old World. In the 1970s, this tool emerged in North America. Despite several decades of science and application, gaps still exist in our knowledge regarding applications for LGDs. From February 2016 to November 2017, we deployed global positioning system transmitters on 4 LGDs on a 20-km2 ranch in Menard County, Texas, USA operated by Texas A&M AgriLife Research to investigate their ...

European Starlings Fly Before They Fledge, Jeremiah L. Psiropoulos, Lisa A. Selner

Human–Wildlife Interactions

Aircraft bird strikes are increasing globally. Bird strikes constitute a major human health and safety risk and result in millions of dollars in economic impacts. Invasive avian species, such as the European starling (Sturnus vulgaris; starlings), have been implicated in bird strikes in North America. Because this species is highly adaptive and has been successful at establishing in new areas, such as airports, it is essential that managers better understand the potential risks and how to mitigate them. Herein we present a case study regarding a novel observation of unique starling nesting behavior that may pose a risk to airport ...


Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith 2019 Brigham Young University

Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith

Human–Wildlife Interactions

Developing the capacity to predict black bear (Ursus americanus; bear) activity in a diversity of habitats will help conserve bear populations and their habitats and minimize human–bear conflicts. This capacity will be particularly important in areas that provide bear habitat and offer backcountry hiking and camping experiences. Bryce Canyon National Park (BRCA), located on the edge of the Paunsaugunt Plateau in southern Utah, USA, provides important bear habitat and offers visitors 12 backcountry campsites. To effectively manage these areas to minimize human–bear conflicts, park managers will need better information about black bear use of these campsites and other ...


A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead 2019 Antioch University of New England

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive ...


A Review Of Equine Laminitis: Risk Factors And Predispositions, Molly C. Henion 2019 University of New Hampshire

A Review Of Equine Laminitis: Risk Factors And Predispositions, Molly C. Henion

Honors Theses and Capstones

Equine laminitis is a disease of the hoof characterized by inflammation or disruption of the sensitive and insensitive laminae located within the hoof. These structures are responsible for maintaining a secure connection between the third phalanx (P3) and the hoof wall. Damage to these laminae can weaken the attachment between the hoof wall and P3, causing separation and eventual rotation of P3. Equine laminitis can result from multiple triggers, but the most commonly seen cases of the disease are those which are related to endocrinopathy and metabolic related issues. This review will focus on determining the metabolic risk factors associated ...
