Analysis Of The Value Of A Ewe In The Wa Sheep Industry, John Young, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock published reports

The WA flock is at a historically low level, however, sheep profitability is at record highs so rebuilding the state flock is an industry priority. Minimising ewe losses is a necessary component of the flock rebuilding. As a result of the feed shortage and possible grain shortage with high prices likely due to demand for grain from the east coast, local farmers may be tempted to underfeed their ewes during the summer/autumn period. Awareness and good information regarding the cost of mis-managing ewe nutrition will help minimize this temptation.

Impact Of An Educational Program On A Year-Round Forage Production And Grazing Management System In Alabama, Lila Karki, Uma Karki

Professional Agricultural Workers Journal

Abstract

Raising animals on supplementary feeds in the lean months is economically unfeasible due to the increasingly high price of grains and commercial feeds. The objective of this study was to estimate the economic impact of educational events on year-round pasture and grazing management. A survey was introduced through SurveyMonkey to 78 trainees to collect data on a pre-structured questionnaire. A conceptual framework of production function was applied to measure the impact of the events using a before vs. after impact assessment approach. Forty-six percent of respondents completed the survey. The results revealed that the educational events had a positive …

Barriers To Management Intensive Grazing By Southern Dairy Farmers, Mohammed Ibrahim, Nalini K. Pattanaik, Brian Cornish

Professional Agricultural Workers Journal

Abstract

Interest in Management Intensive Grazing (MIG) [a situation where grazing animals are moved to a fresh pasture every few days in order to have access to adequate forage] practices by farmers have increased steadily over the years. Many research publications on grazing advocate the financial and environmental benefits of grazing. Understanding the challenges of MIG can be an important piece of information for a dairy farmer. A survey was conducted to determine how farmers in the southeastern region perceive the barriers to the adoption of MIG. A greater percentage of MIG southeastern farmers were satisfied or very satisfied with …

Production Period Of Different Browse Species Suitable For Grazing Small Ruminants, Bidur Paneru, Uma Karki, Shailes Bhattrai, Nevershi Ellis

Professional Agricultural Workers Journal

Abstract

Browse (shrubs, trees, and vines) species are important sources of feed for small ruminants in Alabama and many other states of the U.S. Information on the production period of these species is important to prepare a year-round grazing plan to utilize them well. The objective of the study was to determine the leaf-shedding time of common browse species suitable for small ruminants. This study was conducted at the Atkins Agroforestry and Browse Research and Demonstration Site of Tuskegee University, Alabama. Ten samples of each browse species were tagged, and leaf-yellowing and leaf-fall data collected using photoplots every 14 days …

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Graduate Theses and Dissertations

According to USDA FAS, in 2017, the US was the largest broiler-producing country with 18.696 million metric tons and the second largest exporter of broiler products with 3.075 million metric tons (Brazil is the largest exporter with 3.847 million metric tons). Thus, around 83% of US production is consumed domestically. According to USITC, chickens are the most important protein source in the US, and Americans consume more chicken per capita than any other country. However, while the broiler industry is a key segment of US agriculture, it is underserved by large-scale supply-chain and trade models.

In this study, to fill …

Western Australian Sheep Producer Survey 2018, Mandy Curnow, Janet Conte

Animal production and livestock published reports

This survey was commissioned in 2018 by the Department of Primary Industries and Regional Development (DPIRD), following earlier surveys in 2011 and 2014 conducted as part of national producer surveys for the Cooperative Research Centre for Sheep Innovation (Sheep CRC). This report is therefore able to analyse respondents’ flock management over time.

The surveys were conducted by telephone with producers who had more than 500 sheep and were located in the Medium Rainfall Zone (MRZ) or Cereal Sheep Zone (CSZ). The sample sizes for the 2011, 2014 and 2018 surveys were 369, 368 and 389 respectively.

Optimization Of The Light Environment For Broiler Chickens, Douglas J. Aldridge

Graduate Theses and Dissertations

The use of artificial light sources has been necessitated by the use of fully enclosed rearing facilities for improved environmental control. Light Emitting Diodes (LED) have been developed as a light source that reduce the utilities required to provide equal light to that of incandescent sources. The following reports were carried out to investigate the effects of two light color temperatures, light intensity and light intensity gradients on broiler chicken production and behavior. The first investigation consisting of two consecutive trials investigated the effect of two light color temperatures (2700 K and 5000 K) in addition to the preference for …

Grazing Myths That Reduce Profitability, Gregory S. Halich

Forage Symposium at the Kentucky Cattlemen’s Convention

Many cattle farms have moved to rotational grazing in the past decade, and there are significant benefits associated with this grazing technique. However, one thing that I have noticed is that costs are not always accounted for when it comes to recommended rotational grazing practices. If you ignore costs, partially or fully, you will invariably do too much of whatever you are considering. In this light, I will highlight four grazing recommendations (myths) that many folks are often taking to extremes related to rotational grazing, and one additional myth (generic to grazing style) that is reducing the overall profitability of …

Profitability At Eldon Farms: Guiding Principles, John Genho

Forage Symposium at the Kentucky Cattlemen’s Convention

Eldon Farms is a 7,000-acre farm in the Northern Piedmont of Virginia. Over the past 15 years, we have adopted a grazing program based on three principles. While the specifics of each operation are different, I believe these principles can be applied across a host of situations.

Cost–Benefit Analysis Of Coyote Removal As A Management Option In Texas Cattle Ranching, R. Kyle Brewster, Scott E. Henke, Benjamin L. Turner, John M. Tomeček, Alfonso Ortega-S.

Human–Wildlife Interactions

The monetary value of livestock losses attributed to coyote (Canis latrans) predation in North America has increased during the past 20 years. In Texas, USA alone in 2011, these loses were estimated at $6.9 million. To mitigate coyote-related livestock losses, several lethal and nonlethal control methods have been developed. However, there remains a need for better information to guide management decisions regarding cost-effective predator control strategies for livestock production systems. We acquired data, which was used in the model, from published literature from 1960 to present day, subject matter experts, and anecdotal information on coyote ecology. We developed …

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

Formation of harmful microbes and their associated mycotoxins on rough rice during storage presents negative socioeconomic impacts to producers and consumers. The objective for this study was to investigate the impact of treating rough rice with selected infrared (IR) wavelengths at different IR intensities and heating durations, followed by a tempering step for further inactivation of microbes (mold and bacteria) on the grain. Freshly-harvested long-grain, hybrid, rough rice (XL 745) with initial moisture content (IMC) of 18.4% wet basis (w.b.) was used. Two-hundred grams (200 g) samples of rice were treated at different IR wavelengths (λ), 3.2, 4.5, and 5.8 …

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF) pastures. …

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 …

Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson

Two experiments were conducted to determine animal performance of alternative feeding strategies to heifers grazing endophyte-infected tall fescue during summer months. In Experiment 1, 40 Limousin heifers (261± 40kg initial BW) were stratified by weight and assigned to either a spring harvested tall fescue silage diet or grazing endophyte-infected tall fescue pasture with grain supplement having either natural or artificial shade for 80 days. In Experiment 2, 40 Limousin heifers (277 ± 44kg initial BW) were stratified by weight and assigned to either a traditional grain supplement or feather-meal supplement (rumen bypass arginine supplement) with natural or artificial shade while …

Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth Delay

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Foreign Direct Investment (FDI) has the potential to increase economic activity and improve GDP growth in low-income countries, but can hinder economic development (quality of life improvements) if not sustainable and holistic in manner. Africa serves as a host to many cases of FDI focused on economic growth, but not necessarily improving the quality of life for its citizens. FDI has spread throughout the African continent, where many countries are well endowed with natural resources, like minerals and coal. These economies have experienced rapid GDP growth with few benefits reaching citizens of the host country. Mozambique is a low-income country …
