Modelling Contamination Of Raw Milk With Butyric Acid Bacteria Spores, M. M. M. Vissers, F. Driehuis, P. De Jong, M. C. Te Giffel, J. M. G. Lankveld

IGC Proceedings (1997-2023)

Raw milk contains low concentrations of bacterial endospores, originating from the farm environment (e.g. soil, feeds, faeces). Spores of Clostridium tyrobutyricum, also called butyric acid bacterium (BAB), are of great interest to the dairy industry. They survive milk pasteurisation and cause off-flavours and texture defects in various cheese types. The contamination pathway of BAB spores is well known. Their primary origin is soil. In silage the number of spores will increase if conditions permit BAB growth. The spores are excreted in the cows faeces and are transferred to milk by contaminated teat surfaces. Many factors are involved in the …

Farming For The Future; Managing Lowland Grassland For Biodiversity, Sally Griffin

ORBioM (Open Research BioSciences Meeting)

Grassland is Ireland’s most expansive terrestrial habitat type covering >58% of the land cover but its biodiversity is under serious threat of agricultural intensification or land abandonment. While the decline in Irish grassland biodiversity has been recognised, there is a paucity of research into the restoration of lowland mesotrophic grassland. Most of Ireland’s grasslands are privately farmed mainly for pasture, therefore, appropriate agricultural management techniques for biodiversity restoration are vital. The purpose of this research was to first classify the lowland grassland vegetation in Killarney National Park, Co. Kerry in the west of Ireland (Approx. 244ha). Then to investigate selected …

Examining Farm Financial Management: How Do Small Us Farms Meet Their Agricultural Expenses?, Omobolaji Omobitan, Aditya R. Khanal

Agricultural and Environmental Sciences Faculty Research

Small farms in the US have significant challenges in financial management. This study examines how small farmers undertake farm financial management to meet their agricultural and farm-related spending and expenses. Using primary survey data from Tennessee, the study investigates the factors influencing the extent of use of five financing sources to meet the spending and expenses: cash/fund directly generated from the sale of agricultural products, farmer’s past savings, farm household’s off-farm income, income/incentives from government payments, and external loans. Using negative binomial regression estimation of generalized linear models, findings suggest that the decision on the use of financing sources is …

This study was conducted to investigate the farm management, focusing on the regional difference and the presence of cattle farming in the country. Interview was carried out on 30 farms from B Province in the Centre-West Region consisting of 8 non-cattle owners (BNs) and 22 cattle owners (BCs), and on 9 farms of cattle owners from H Province in the Haut-Bassins Region (HCs) in November 2013. The average household sizes of BNs, BCs and HCs were 16.5, 27.2 and 31.3, respectively. The ratios of …

Bird Communities In African Cocoa Agroforestry Are Diverse But Lack Specialized Insectivores, Crinan Jarrett, Thomas B. Smith, Tabe T.R. Claire, Diogo F. Ferreira, Melanie Tchoumbou, Malange N.F. Elikwo, Jared D. Wolfe, Kristin Brzeski, Andreanna J. Welch, Rachid Hanna, Luke L. Powell

Michigan Tech Publications

Forests are being converted to agriculture throughout the Afrotropics, driving declines in sensitive rainforest taxa such as understorey birds. The ongoing expansion of cocoa agriculture, a common small-scale farming commodity, has contributed to the loss of 80% rainforest cover in some African countries. African cocoa farms may provide habitat for biodiversity, yet little is known about their suitability for vertebrate fauna, or the effect of farm management on animal communities. Here, we report the first in-depth investigation into avian diversity and community composition in African cocoa, by assembling a dataset of 9,566 individual birds caught across 83 sites over 30 …

Turkish Journal of Veterinary & Animal Sciences

The study examined the knowledge, beliefs, and attitudinal drivers of technical staff and breeders regarding tail docking and the incidence of docking on large-scale dairy farms (≥100 cattle) in Turkey. Survey responses were analyzed using the Mann?Whitney U test to determine attitudinal differences between respondents who self-reported docking tails or not docking their cattle. Using face-toface interviews of 210 respondents at 206 Turkish dairy farms was carried out. Tail docking procedures were practiced on 27.1% of the surveyed farms. At the time of the tail docking, 57.9% of cattle were less than 12 months of age. The most frequent tail …

Determination Of Timeliness Cost Using Method Of Average Workability Robability Based On Reliability Function Of Farm Tractors, Mohammad Poozesh, Javad Tarighi

Emirates Journal for Engineering Research

There is an optimum time for implementing field operation of a crop in each region. If the operation were accomplished sooner or later, it might cause a reduction in yield quantity and quality that is named timeliness cost. The purpose of this study is to survey the timeliness cost of harvesting operation of sugar cane based on reliability function of MF285 tractors operating in Debal Khazaei Agro-Industry Co. in Khuzestan, a province of Iran. MF285 tractors have low reliability in Iran, and due to their low reliability have an uncertainty in implementation of farm operation, though it is not …

Evaluating The Economic Costs And Land Value Implications Of Implementing Cover Crops In Kentucky, Robert C. Ellis

Theses and Dissertations--Agricultural Economics

This thesis is comprised of two essays regarding the costs and impact of land values due to cover crops. This first essay uses a linear-programming resource allocation model combined with sequencing and machinery selection to optimize the practices and machinery utilization of a hypothetical western Kentucky grain farm. This was accomplished through maximizing returns over selected costs at various acreage adoption levels. Additionally, a decision tool was developed to assess the costs related to cover crop adoption. The results show a $30 per acre cost to adopt 1000 acres of cover crops when no benefits were considered. The second essay …

Sustainability Partnerships And Viticulture Management In California, Vicken Hillis, Mark Lubell, Matthew Hoffman

Human-Environment Systems Research Center Faculty Publications and Presentations

Agricultural regions in the United States are experimenting with sustainability partnerships that, among other goals, seek to improve growers' ability to manage their vineyards sustainably. In this paper, we analyze the association between winegrape grower participation in sustainability partnership activities and practice adoption in three winegrowing regions of California. Using data gathered from a survey of 822 winegrape growers, we find a positive association between participation and adoption of sustainable practices, which holds most strongly for practices in which the perceived private benefits outweigh the costs, and for growers with relatively dense social networks. We highlight the mechanisms by which …

Decision Support Software For Palmer Amaranth Weed Control, Karen Renee Lindsay

Graduate Theses and Dissertations

Herbicide-resistant Palmer amaranth [Amaranthus palmeri (S.) Wats.] has been identified as one of the most troublesome weeds, specifically for corn (Zea mays L.), cotton (Gossypium hirsutum L.), and soybean [Glycine max (L.) Merr.] producers in the southern United States. The use of herbicide technology remains the most widely used method of weed control, despite the evolution of herbicide-resistant Palmer amaranth. Therefore, a need currently exists for research and extension education to encourage the adoption of Integrated Pest Management (IPM) to address the problem of herbicide-resistant Palmer amaranth in the southern United States. By equipping crop producers, educators, and weed management …

Two Essays On Large Agricultural Producer Buying Behaviors, Jacqueline K. Holland

Open Access Theses

The trend of consolidation of large farms into high volume operations has continued over the past 30 years. Large farm management is a juggling act of a variety of biological processes, financial management, technology adaptation, and human resource development activities. This research looks to provide insights into the underlying management psychology of those large farmers to serve not only as a benchmark for other producers, but to provide customer information to agribusinesses so these firms can strengthen their relationships with their large farmer customers. The first part of this analysis will use Best-Worst modeling to examine five predetermined success factors …

Agriculture In New York State : Farm Size And Its Implications To Farmland Protection And Biodiversity Conservation, Julianna Marie Potter

Legacy Theses & Dissertations (2009 - 2024)

In the United States there are 939 million acres of land held by ranchers and farmers. Conservation of this agricultural landscape is critical to the protection of biodiversity. Management of agricultural land is also associated with the success of biodiversity protection efforts in protected areas, including parks and preserves, as well as outside protected areas. Sustained viability of the New York farming sector will enhance and secure biodiversity on farmland, as viable farms will remain part of the landscape.

Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta

Bulletins 4000 -

Lucerne, often regarded as the queen of forages, has been used in agriculture for centuries. In Western Australia, however, its potential has never been fully realised despite its well-documented ability to dewater soils and reduce groundwater recharge. Over the years adoption has been limited by a range of factors including pests and diseases, soil acidity, grazing management and economics. During the last decade research has addressed these issues, paving the way for much greater impact at the farm and catchment level.

The Queen Of American Agriculture: A Biography Of Virginia Claypool Meredith, Frederick Whitford, Andrew G. Martin, Phyllis Mattheis

The Founders Series

Virginia Claypool Meredith's role in directly managing the affairs of a large and prosperous farm in east-central Indiana opened doors that were often closed to women in late nineteenth century America. Her status allowed her to campaign for the education of women, in general, and rural women, in particular. While striving to change society's expectations for women, she also gave voice to the important role of women in the home. A lifetime of dedication made Virginia Meredith "the most remarkable woman in Indiana" and the "Queen of American Agriculture." Meredith was also an integral part of the history of Purdue …
