Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes
Alexander Hayes Mr.
Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …

Food, Fibre And The Future : Report On Surveys Of Students’ And Teachers’ Knowledge And Understanding Of Primary Industries, Kylie Hillman, Sarah Buckley
Dr Sarah Buckley
Primary Industry plays a vital role in Australian’s economy and society, but the gap between rural and urban communities is growing, contributing to a lack of understanding of where food and other basic necessities of life come from. The goal of the Primary Industries Education Foundation (PIEF) is to provide a source of information on primary industries for educators, to better equip students with not only knowledge about what goes into their food and fibres but also what career opportunities exist in primary industries. In 2010, PIEF contracted the Australian Council for Educational Research (ACER) to design and conduct a …

Within-Plant Distribution Of Volatile Compounds On The Leaf Surface Of Flourensia Cernua, Rick Estell, Darren James, Ed Frederickson, Dean Anderson
Ed L. Frederickson
We are using Flourensia cernua as a shrub model to study how terpenes affect livestock herbivory. Two experiments were conducted to examine distribution of volatile chemicals within a plant in an effort to minimize sample variability. In Experiment 1, leaves (current year's growth) were collected from 20 tarbush plants. Two leaders were sampled from each of three positions (outer canopy, subcanopy, and basal) in all four quadrants (based on ordinal direction). In Experiment 2, 10 leaders of current year's growth were removed from another 20 plants. Leaders were collected from the outer canopy of each quadrant and separated into thirds …

Characterizing Overall Response To Two-Shot Vaccination For Bvdv Type 2 In Angus Weanling Calves, Richard Tait, Erika Downey, Mary Mayes, Julia Ridpath, Dorian Garrick, James Reecy
Richard G. Tait Jr.
Vaccination is a management strategy utilized to help reduce prevalence of bovine respiratory disease in feedlots. However, not all animals respond similarly to vaccinations. It is believed that an animal’s genetics control part of the ability to respond to a vaccination protocol. In order to evaluate the genetic control of a new trait such as response to vaccination, it is important to understand the non-genetic factors that affect an animal’s response to vaccination. The objective of this study was to characterize the non-genetic factors affecting overall response to a two-shot vaccination for bovine viral diarrhea virus type 2 (BVDV2) in …

Evaluation Of Energy Values Of Various Oil Sources When Fed To Broiler Chicks, G. Murugesan, Brian Kerr, Michael Persia
G. R. Murugesan
The nitrogen-corrected apparent metabolizable energy (AMEn) values of seven different oil and fat sources used in broiler diets, primarily across the Midwestern US, were determined in a digestibility experiment. Fifteen days old, Ross 308 male broiler chicks were fed diets containing each oil or fat source at 0%, 3%, 6%, and 9% inclusion levels for 7 days before excreta samples were collected to analyze AMEn on day 21. The AMEn was calculated using 2 different methods, including a linear equation slope method as well as calculating the difference between basal diet and oil containing diets. The AMEn values determined by …

Uses Of Wild Plants In Ndumba, Eastern Highlands Province, Terence Hays
Terence Hays
For Papua New Guineans,l as well as for those who wish to understand them better, traiditional knowledge of the local natural environment is a priceless resource. In the face of increasing commitments to a cash economy, however, many communities are rapidly losing their awareness and appreciation of the rich animal and plant worlds which are immediately available to them. As Powell has recently observed (1976), the recorded information regarding traditional plant knowledge and uses has tended to be widely-scattered in the literature and relatively difficult to access, especially for those who stand to benefit the most from it. A recent …

Purification And Characterization Of Novel Nucleases From A Thermophilic Fungus, Kyle Landry
Kyle S Landry
A thermophilic fungus was isolated from composted horse manure. The organism was as a Chaetomium sp. by sequencing the highly conserved ITS region of the fungus and comparing to known regions in a genomic database and was referred to as TM-417. TM-417 was found to have an optimal growth temperature of 45 oC and an optimal pH of 7.0. An extracellular DNase and RNase was found to be produced by the isolate and were purified 145.58-fold and 127.6-fold respectively using a combination of size exclusion chromatography and a novel affinity membrane purification system. The extent of purification was determined …

G00-1778 Field Windbreaks, James Brandle, Laurie Hodges
Laurie Hodges
gricultural producers face many challenges as they try to balance efficient production systems with increasing environmental demands. For these systems to be successful, they must optimize the balance between inputs and final production. Field windbreaks are one way to increase yields while at the same time reducing inputs and improving both environmental quality and production efficiency. Windbreaks reduce wind speed and alter the microclimate in sheltered areas. Field windbreaks reduce wind erosion and the damage to crops caused by wind-blown soil. They improve water use efficiency, reduce risks associated with drought, and manage blowing snow.
Field windbreaks provide positive economic …

An Assessment Of Behavioural Syndromes In Rangeland-Raised Beef Cattle, Robert Wesley, Andrés Cibils, J. Mulliniks, Emily Pollak, Mark Petersen, Ed Frederickson
Ed L. Frederickson
Individuals in most animal groups exhibit consistent behavioural differences across situations or over time known as behavioural syndromes. We conducted a study with a herd of young rangeland-raised cows to determine whether animals exhibited consistent differences in foraging behaviours across contexts (confinement vs. rangeland pasture) and could be clustered into behavioural type groups on the basis of a suite of correlated behaviours. We also investigated whether cows with different behavioural types performed differently in this environment. Supplement consumption rate (SCR) in confinement was used to select two groups of cows (fast eaters vs. slow eaters). This classification was validated by …

Ed L. Frederickson
Electronic tracking provides a unique way to document behaviour by cows on a continuous basis. Over 2 years 17 beef cows with calves were fitted with global positioning system (GPS) devices programmed to record uncorrected GPS locations at 1-s intervals in a semi-desert rangeland. Each cow was periodically observed during daylight hours and foraging, walking and stationary (standing/lying) activity times were recorded across days and individual cows to calculate a mean travel rate for each activity. Data without observers present were collected immediately preceding and following the abrupt weaning of calves at between 223 and 234 days of age to …

The present study investigate the effect of herbal water extract prepared from Allium sativum and Cinnamomum verum on the viability of lactic acid bacteria (Lactobacillus spp and Streptococcus thermophilus) in cow- and camel-milk yogurts during 21 day refrigerated storage. The organoleptic properties of fresh-yogurts were evaluated. Lactobacillus spp count for fresh cow milk-yogurts (0 day) in both present and absent of C. verum and A. sativum was ranged from 1.4×0 6 to 2.1×10 6 cfu/mL. These values were not significantly changed throughout the 21 days of refrigerated storage. Lactobacillusspp count in fresh plain camel milk- yogurt was 13.2×10 6 cfu/mL …

Foraging Behavior Of Heritage Versus Recently Introduced Herbivores On Desert Landscapes Of The American Southwest, Ed Frederickson, H. Peinetti, Debra Peters, Andres Cibils, J. Roacho-Estrada, Andrea Laliberte
Ed L. Frederickson
Since the 1800s managed grasslands and shrublands of the arid American Southwest have been grazed predominantly by cattle originally bred for temperate climates in northern Europe. A heritage breed, the criollo cattle, has survived in northern Mexico for more than 400 years under desert-like conditions of low and variable rainfall, hot temperatures in the growing season, and both spatially and temporally scarce levels of primary production. We tested the hypothesis that the heritage breed has a broader spatial foraging distribution under harsh environmental conditions, and that its distribution is driven by environmental variables which differ from those that control the …
