Exploratory Evaluation Of Handler Performance And Processing-Related Outcomes During Cattle Handling, Morgan Marquardt

Department of Animal Science: Dissertations, Theses, and Student Research

Animals have several critical roles in society, including the production of food and fiber, and companionship. Contact with animals has been shown to benefit human physical and mental health, yet little research has investigated the impact that humans have on animals. Handler skill may considerably affect the extent to which humans influence animal health and wellbeing, and this may be a critical consideration for animal agriculture. Objective assessment of cattle handler skill has received limited attention in the scientific literature, despite its importance to human safety and animal welfare. When compared to less skilled handlers, highly skilled cattle handlers may …

One Health Interventions And Challenges Under Rural African Smallholder Farmer Settings: A Scoping Review, Evanson R. Omuse, Honest Machekano, Bonoukpoè M. Sokame, Daniel M. Mutyambai, Thomas Dubois, Sevgan Subramanian, Frank Chidawanyika

All Peer-Reviewed Publications

The global human population is rapidly increasing, escalating interactions of people, animals and the environment. This has led to more convoluted health challenges, for which African smallholder farmers bear the brunt. The One Health (OH) approach recognises the interconnectedness of these health challenges and thus follows a transdisciplinary approach involving diverse stakeholders to address them. Although there have recently been global concerted efforts and studies on OH, an information gap exists in Africa, particularly regarding smallholder farmers and their needs. Additionally, evaluation frameworks and outcome metrics for OH initiatives are still unclear. Thus, this study was conducted to critically map …

Self-Mustering Yards For Pastoral Livestock Management, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Self-mustering yards (SMYs) are an important component of effective total grazing management in the pastoral regions. These yards are used to self-muster cattle, sheep and goats, as well as native browsers and feral animals as they enter the yards to access the water point.

Managing The Beef Breeder Herd In Southern Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Kilograms of beef produced per hectare is a significant driver of profit for a beef business. Cow longevity (length of productive life) plays an important role in achieving a profitable business. A balanced approach to genetic selection and nutritional management are essential factors underpinning the efficiency of the breeding herd.

Roly Poly And Its Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Roly poly, also known as prickly saltwort or tumbleweed (Salsola australis), is a native species found throughout Australia. The dead plants can break off at ground level, forming the ‘tumbleweeds’ seen in movies.

Like most summer weeds, roly poly uses soil moisture and nutrients that would otherwise be available to the following crop. The time taken to clear uncontrolled plants can delay seeding.

Livestock will graze the young plants; however, they will not eat the mature plants and are injured by the prickly leaves.

Pasture Data Reconciliation Of The South West Agricultural Zone Of Western Australia September 2024, Tafesse Estifanos, Amir Abadi Ghadim, Paul Mattingley, Kate Pritchett, Tony Della Bosca

Animal production and livestock published reports

Western Australia’s (WA) agricultural land use system features extensive pasture land vital for grazing sheep and cattle. Most pastures in the south west of Western Australia consist of annual species that grow during the cool, wet winters of the Mediterranean climate and senesce in the warm to hot, dry summers. Understanding the spatial distribution of pasture areas within the context of mixed farming is essential for developing effective land management strategies to enhance livestock production and profitability through balanced pasture supply and demand.

This report focuses on reconciling pasture area data for the south-west of Western Australia’s agricultural zone across …

Capeweed And Its Management, Department Of Primary Industries And Regional Development, Western Australia

Texas A&M Beef Cattle Short Course: Program Evaluation, Nicola Oosthuizen, Pedro Fontes, Graham C. Lamb, Jason J. Cleere

Journal of Extension

Survey results (n = 3,748) collected over a period of 7 years from the Texas A&M Beef Cattle Short Course (BCSC) were analyzed to evaluate course demographics and the impact of the course on attendees. Results of this survey demonstrate that attendee demographics of the BCSC are representative of beef cattle producers in the United States and that the BCSC is effective at delivering information that positively impacts beef production in Texas. Extension professionals can make use of these findings to tailor future education programs to better serve the needs of beef cattle producers nation-wide.

Tedera: A Guide To Growing And Utilising This Perennial Pasture Legume, Daniel Real

Animal production and livestock published reports

The commercial release of a new pasture species is a rare and, potentially, important event. In the case of tedera (Bituminaria bituminosa var. albomarginata) we have a novel perennial pasture legume with characteristics which set it apart from anything currently available to growers in Australia or internationally.

Specifically, it is a drought-tolerant, highly productive perennial pasture with the capacity to provide nutritious forage, especially when other feed sources are scarce. Its reaction to drought is in contrast with the few successful perennial legumes available for Mediterranean climatic zones, such as lucerne, as it retains green leaves when water stressed, allowing …

Hotline Number To Reach And Offer Agricultural Information To Plain Anabaptists During The Covid-19 Workplace Closures, Emily Shoop, Carly Becker, Nathan Glenn Briggs, Danielle Smarsh

Journal of Amish and Plain Anabaptist Studies

The Penn State Extension Animal Systems Team developed a toll-free hotline phone number to convey short educational messages to maintain contact and outreach to Pennsylvania’s animal producing Amish, Mennonite, and other plain Anabaptist populations. During the COVID-19 pandemic, Penn State Extension’s programming went largely online via webinars, online courses, and emails. This change in programming excluded a large sector of Pennsylvania farmers who do not use or have access to the internet and, as such, were liable to miss important best management practice reviews and timely updates in animal agriculture. The Animal Systems Hotline offered callers the choice to listen …

Managing And Buying Bulls, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Weaning percentage and therefore conception rate, can significantly influence profitability in the breeder herd.

Bulls need to be managed to optimise their performance for the mating period to maximise conception rates. For producers retaining females in the breeding herd, bulls can have a significant impact on future herd productivity through the genetics they pass on.

Various tools are available to assess how a bull will perform before purchase, including visual appraisal, obtaining a bull breeding soundness examination (BBSE) and utilising estimated breeding values (EBVs).

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus is an important component of bodily functions and is critical for adequate growth and development. This experiment evaluated the effect of maternal phosphorus intake on the growth and health of the calves. Treatments were 1) a free-choice mineral containing no supplemental P or 2) a free-choice mineral with 4% supplemental phosphorus. Primiparous, or pregnant for the first time, crossbred Angus beef cows (n = 36) were stratified by body weight and pregnancy status (bred by artificial insemination or natural service) then assigned to pasture groups (4 groups, 2/treatment, 9 heifers/group). These bred heifers had been receiving these same dietary …

Analyzing The Management Practices Of East Texas Beef Cattle Producers, Hiliary Cheyenne Swor

Electronic Theses and Dissertations

A survey of East Texas beef cattle producers was designed to evaluate the management practices that were prevalent in the area. Demographic and cattle operation data from 103 respondents were analyzed using SPSS (Version 25; Chicago, IL). This electronic-based survey was distributed through Qualtrics. Respondents were located in Angelina, Nacogdoches, or Cherokee county. Most producers (38.8%) had a Bachelor’s degree. A negative correlation was established between castration method and weaning weight (p = - 0.204). Calves were weaned 50 pounds heavier when band or surgically castrated. Females were less likely to castrate their calves or utilize a mineral program. Approximately, …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Feeding Corn Milling Co-Products To Feedlot Cattle, 3rd Edition, Galen E. Erickson, Crystal D. Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Two primary types of milling processes currently exist, resulting in quite different feed products. These processing plants produce and market a variety of feed products, but in general, the dry milling process produces distillers grains plus solubles (DGS), and the wet milling process produces corn gluten feed (CGF). These feeds can be marketed as wet feeds, or they can be dried and marketed as either dry corn gluten feed (DCGF) or dry distillers grains (DDG) with or without solubles.

For the purposes of this report, wet corn gluten feed (WCGF), wet distillers grains plus solubles (WDGS), DCGF and dried …

Feeding Corn Milling Co-Products To Forage Fed Cattle, 1st Edition, Aaron Stalker, Rick Rasby, Galen E. Erickson, Crystal Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Beef calves from weaning until they enter feedlots, developing heifers, and beef cows are fed primarily forage diets. Especially in the winter, forages are low in protein and phosphorus and need to be supplemented. Corn milling co-products are excellent sources of both protein and phosphorus and fi t nicely into winter supplementation programs. Corn milling co-products are also an excellent source of energy and are particularly well suited to forage based diets.

Two primary types of milling processes currently exist, resulting in quite diff erent feed products. The dry milling process produces distillers grains plus solubles (DGS), and the …

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia

Animal production and livestock published reports

A seminar and workshop was held at Fitzroy Crossing in October 1993 to address the consequences of flooding to landholders and communities.

Damage to flood plain fencing was identified as one of the major concerns to landholders.

An outcome from the workshop was the decision to draw on local knowledge and collate information on options for fence and floodgate designs.

This information was to be made available to land holders and other interested parties - hence this publication.

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …

Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside

Animal production and livestock published reports

The role of the Rangeland Management Branch is to promote the sustained economic use of the rangeland resource. It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …

Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin

Bulletins - 3000 - 3999

This article deals with those native, naturalized and cultivated plants, which by virtue of contained cyanogenetic glycosides, are known to be poisonous or potentially poisonous to livestock in Western Australia.

Cyanogenetic glycosides are chemical compounds which contain a cyanogen (cyanide) radical combined with a sugar molecule. The sugar moiety may differ in glycosides obtained from different plants, and as a consequence glycosides from different plants, containing different sugar moieties, may be given different names.

When a cyanogenetic glycoside is broken down by enzyme action, through injury to the plant or by microbial action in the digestive system of the animal, …

Bulletin No 3966 - Vitamin A And Animal Health, J. Johnson

Bulletins - 3000 - 3999

Vitamin A is one of the essential vitamins for animal health. Grazing animals obtain their vitamin A requirements mostly from the carotene in green feed. This carotene is converted to Vitamin A in the intestinal wall and is passed to the liver and to a less extent the kidneys for storage. Some carotene also passes direct to the liver where it is stored before it is converted to vitamin A.

When dry pastures, hay and grains (except maize) are low in carotene content this ability of the animals to store vitamin A means that they usually have enough when there …

Beef Marketing As A Guide To Production Techniques, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture
