Pastoralist Conservation: Local Ecological Knowledge And Collective Action For Grassland Conservation In Sierra De Segura (Spain), P. Sanosa-Cols, F. Ravera, F. Dominguez, M. Ventura

IGC Proceedings (1977-2023)

Even if Pastoralism is not practised anymore by a majority of families in the Sierra de Segura (south-eastern Andalusia, Spain), it is still considered a paradigmatic way of life and management of its highlands and a key cultural heritage deeply rooted in local identity. In this article we explore two pastoral communities of this region, Santiago and Pontones, with their body of situated knowledge of the territory and natural resources, which helps pastoralists to organize their livelihoods, while requiring collective organization to manage access to grasslands. Through an ethnographic research based on participant observation and in-depth interviews, we explore the …

Intensification Of Pastoralism As A Driver Of Degradation In The Algerian Steppe, S. Bencherif, P. Manzano

IGC Proceedings (1977-2023)

Land degradation linked to pastoralism use has been a worldwide concern for decades. A biological approach has often been use to understand such phenomena, usually disregarding economic and social factors. Radical transformations of pastoralism at the Algerian steppe constitute a good case study to provide an integrated understanding and to better orient development in other pastoralist areas across the world. Different actions by the public sector since the 1960s, as well as the land legislation adopted and the strong agricultural subventions during 2000-2010, have favored a massive conversion of land and resource management. This translates into conversion of many pastures …

Perceptions Of Rangeland Degradation In The Peruvian Altiplano Dry Puna And Implications, C. Turin, J. Gilles

IGC Proceedings (1977-2023)

The Peruvian altiplano’s dry puna is the main feed source for specialized alpaca pastoralist systems. Experts argue that rangelands are severely degraded and have formulated policies and programs to address this. However, these programs have had little success. This paper presents a qualitative case study of the perceptions of rangeland degradation held in three Aymara communities, by range scientists of academia, personnel of NGOs operating in the region and by government officers. We found that each of these groups had distinct views of the level and causes of degradation in the region. Differences in perceptions undermined cooperation and trust between …

Endangered Sustainable Innovation: Indigenous Milk Hygiene And Preservation Techniques By Maasai Too Valuable To Lose, J. Y. Laffa, C. R. Mcculloch, D. Schoder

IGC Proceedings (1977-2023)

The indigenous Parakuyo Maasai communities of Tanzania are traditional pastoralists who depend on fresh cow’s milk as a staple food. However, the arid climate and a lack of clean water challenge milk production and conventional milk hygiene practices.

By conducting informational interviews in eight Parakuyo Maasai regions and 13 districts of Tanzania we sought to identify the key indigenous plants preferred and establish their traditional manner of use. A semi-structured questionnaire was designed to: (i) determine the plants used, (ii) the parts used, (iii) methods of preparation and utensil smoking, (iv) therapeutic applications and associated health benefits of these plants, …

Developing A Glossary Of People-Focused Terms Related To Rangelands And Grasslands, Dana Kelly, Katherine I. Johnsen, Chris Magero, Tungalag Ulambayer, Ann Waters-Bayer

IGC Proceedings (1977-2023)

Excellent glossaries on rangelands and grasslands have been developed by the Society for Range Management (SRM), the International Grassland Congress (IGC) and the International Rangeland Congress (IRC). However, these are largely confined to biophysical and technical terminology and contain very few concepts referring to social, institutional and policy aspects of using rangelands and grasslands. After the 10^th IRC in Saskatoon, Canada, in 2016, an informal group started to develop a glossary of such “people-focused” terms. The short and non-academic definitions are meant to improve communication and understanding by users/practitioners in rangeland and grassland management, policymakers, teachers, students, journalists and …

Could Cheese Be The Missing, Hard, Stable Currency To Fortify Self-Sufficiency Of Pastoralist Communities?, D. Schoder, J. Y. Laffa

IGC Proceedings (1977-2023)

Traditional pastoral existence in Africa has always necessitated close, sustainable interaction with a harsh natural environment. Pastoralists, such as the indigenous Parakuyo Maasai of Tanzania traditionally depend on fresh cow’s milk as a staple. They are among the few African ethnic groups that still live as small, socially intact associations close to nature. Unfortunately, fresh milk is difficult to store and inevitably, times of plenty fluctuate with the times of hunger that threaten cultural retreat. Milk storage is particularly challenging in an arid climate without refrigeration and at such times, survival takes precedence over prosperity. We describe an ongoing pilot …

Comparative Analysis Of Cbrm Cases In Kenya, Ethiopia And Tunisia, I. N. Nganga, L. W. Robinson, B. Eba, F. Flintan, E. M. Ontiri, M. Sghaier, N. H. Abdu, S. S. Moiko

IGC Proceedings (1977-2023)

In various countries, development and conservation organizations and national policymakers have been experimenting with ways of applying the community-based natural resource management approach to the unique social and biophysical characteristics of pastoralist rangeland settings, with mixed results. We carried out comparative case study research on community-based rangeland management (CBRM) in a variety of settings in Ethiopia, Kenya and Tunisia with the objective of identifying what kinds of strategies and methods work in which social and ecological contexts. We used an “options by context” approach guided by a research protocol that includes key variables and descriptors for characterizing the implementing organization’s …

Comparative Analysis Of Agri-Food Systems For Extensive Livestock In The High Pyrenees And Creation Of A Multicriterian Tool For Its Evaluation, Laia Motos, Federica Ravera

IGC Proceedings (1977-2023)

The main objective of this study is to compare the different agri-food systems of extensive livestock (ecological and conventional) of big and small ruminants (cattle and sheep respectively) in high Pyrenees. This objective is formulated by looking at the general lack of knowledge of the population regarding the functionality of these systems, the changes of management that have been introduced in the recent years, especially in terms of commercialization, and the different capacity of response of extensive livestock systems to climate change and other socio-economic complementary changes. Attributes and indicators have been selected for the comparative evaluation of livestock systems, …

Analysis Of Rangeland Perceptions Among Potential Land Redistribution Beneficiaries In South Africa: How Well Do Potential Emerging Farmers Know Their Rangelands?, S. Zantsi

IGC Proceedings (1977-2023)

Sound rangeland management is one of the key factors for a successful and viable commercial livestock production in grass fed production systems. However, such knowledge is perceived to be lacking in small-scale livestock farmers, who farm on degraded and overgrazed communal rangelands despite being regarded as prime beneficiaries of the land redistribution programme in the stalling South African land reform. Largely, it is also not known in details how much the potential future commercial farmers know about their rangelands. This study analyses perception of the prime land redistribution beneficiaries—potential emerging farmers, who were surveyed randomly in three South African provinces. …

Age Adjusted Comorbidity Risk Index Does Not Predict Outcomes In An Autologous Hematopoietic Stem Cell Transplant Population, Dylan Barth, Michael Singleton, Gregory Monohan, Brian Mcclune, Val Adams

Pharmacy Practice and Science Faculty Publications

The hematopoietic comorbidity risk index (HCT-CI) is a pre-transplant risk assessment tool used to prognosticate morbidity and mortality of patients undergoing allogeneic hematopoietic stem cell transplantation. Recently, the HCT-CI was updated to include an age component (HCT-CI-age). Although other studies have validated this tool in allogeneic stem cell transplant recipients, it has never been studied in an autologous transplant patient population. We retrospectively reviewed 181 patients who underwent their first autologous hematopoietic stem cell transplant. We aimed (1) to assess whether an HCT-CI score of 3 or greater is associated with greater mean transplant hospital days, greater total hospital days, …

Subsequent Ultrasonographic Non-Visualization Of The Ovaries Is Hastened In Women With Only One Ovary Visualized Initially, Edward J. Pavlik, Hannah Fancher, Charles S. Dietrich, John R. Van Nagell Jr.

Obstetrics and Gynecology Faculty Publications

Because the effects of age, menopausal status, weight and body mass index (BMI) on ovarian detectability by transvaginal ultrasound (TVS) have not been established, we determined their contributions to TVS visualization of the ovaries when one or both ovaries are visualized on the first ultrasound exam. A total of 29,877 women that had both ovaries visualized on their first exam were followed over 202,639 prospective TVS exams and 9703 women that had only one ovary visualized on their first exam were followed over 63,702 ultrasonography exams. All images were reviewed by a physician. While non-visualization of both ovaries increased with …

An Analysis Of Community-Based Values Informing Land Management On The Midwestern Prairie Band Potawatomi Nation Of Kansas, Usa, Heidi Mehl, Diana L. Restrepo-Osorio, Melinda Howard, Cynthia Annett

IGC Proceedings (1977-2023)

The focus of this study is to examine the interface between land management practices and values within a tribal community in rural midwestern North America. The Prairie Band Potawatomi Nation (PBPN) reside on a tribal reservation with a checkerboard distribution amongst private, non-tribal landowners. Previous studies have indicated that landowners may have different value-systems leading to variations in land-management practices. This can impose discontinuous land management in areas within shared biological boundaries, such as watersheds, especially between tribal and non-tribal entities. Preliminary spatial analysis in and around the PBPN landscape determined that the tribally-managed lands present more vegetative cover per …

A Policy Brief On Adopting The Somali Camel For Enhanced Profitability And Pastoral Resilience In Northern Kenya, Simon G. Kuria, A. O. Adongo, S. Murithi, O. K. Koech, J. T. Njoka, P. Kamande

IGC Proceedings (1977-2023)

Persistent drought and high temperatures in Isiolo and Marsabit counties of northern Kenya repeatedly devastate livestock herds particularly cattle making the pastoralists less resilient, more vulnerable to climate change and poor. To address this challenge, an IGAD funded project promoted adoption of Somali camel breed, trained farmers on improved management and also estimated potential profitability of rearing the camel. Through the project, trainers were trained and facilitated to train 240 peri-urban Somali camel producers in Isiolo and Marsabit on breeding, health, routine husbandry and marketing. Impact study documenting positive stories of change was conducted at the end. Producers who hitherto …

Red Clover Improves The Energy To Protein Balance Of Lucerne-Grass Herbage, X. Godin, Gaëtan F. Tremblay, P. Seguin, S. Bittman, D. Hunt, J. Hakl, G. Bélanger, M.-N. Thivierge, A. Bertrand, M. Thériault, A. Claessens

IGC Proceedings (1977-2023)

Low ratio of readily fermentable carbohydrate to soluble protein concentrations in lucerne (Medicago sativa L.) leads to inefficient use of herbage N by ruminants. To improve the energy to protein balance in lucerne-grass herbage, four proportions of lucerne:red clover (Trifolium pratense L.) were compared in mixtures with and without grasses: timothy (Phleum pratense L.) and tall fescue (Schedonorus arundinaceus Schreb. Dumort.) in Quebec (QC, Canada). In the first post-seeding year, red clover proportion averaged (across grasses and four harvests) 0, 37, 59, and 74% in herbage mixtures. Increasing the proportion of red clover caused a slight …

Structural Features Of Condensed Tannins Influence Their Antimethanogenic Potential In Forage Plants, S. Verma, J.-P. Salminen, S. Wolffram, F. Taube, R. Blank, A. Susenbeth, C. Malisch

IGC Proceedings (1977-2023)

Despite years of research on the antimethanogenic potential of condensed tannins (CT), their large-scale application is inhibited by a substantial variability in previous studies with regards to their impact on ruminant nutrition. This variability mainly results from the complexity of CT structures, and their impact on methane emissions is often unaccounted for. Hence, this study (a) evaluated the variability in antimethanogenic potential across six forage species, (b) linked methane emissions to tannin activity, and (c) determined the impact of CT structural features on methane abatement. Six forage species were grown in a greenhouse under controlled environmental conditions, namely, sainfoin ( …

Round Bale Silage – Farmer Results In Kentucky, Jimmy C. Henning, Jeff Lehmkuhler, Brandon Sears, Corinne Belton, Levi Berg, Don Sorrell, April Wilhoit

Kentucky Alfalfa and Stored Forage Conference

The ability to make silage in round bale packages allows producers to avoid rain damage and produce high quality stored forage. The proliferation of bale wrappers (both individual and inline types) has made this technology more available to producers. Although the process for making baleage is well documented, producers have experienced poor fermentation and in some cases botulism toxicity from baleage. The parameters of good silage are well known and include pH below 5.0 and lactic acid concentrations above 3% on a DM basis. However, tests of farmer produced baleage reveals that often these target values are not achieved. To …

Alfalfa Insect Update: 2021 Growing Season, Lee H. Townsend

Kentucky Alfalfa and Stored Forage Conference

Alfalfa weevils (AW) and fall armyworms (FAW) were newsmakers for very different reasons during the 2021 alfalfa growing season. An AW control failure with a pyrethroid in Kentucky drew attention to practices to manage insecticide resistance. A regional outbreak of FAWs resulted in significant damage to alfalfa and grasses along with a reminder of the unpredictable nature and difficult detection of this pest. While there are several effective FAW control options, it is challenging is to detect infestations in time to act.

Harvest Timing And Moisture Determination: Forage Drying Rates And Moisture Probe Accuracy, Benjamin M. Conner, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Scott County Kentucky currently has a beef cattle herd of 28,509 head (USDA, 2017). These cattle utilize forage as a large part of their diets. Baleage is bales of wilted, high moisture forage which have been wrapped in several layers of UV‐resistant plastic and allowed to ensile like traditional chopped silage (Henning et al., 2021). Baleage has become another way for farmers to harvest and store forage to be used in cattle diets. It has some advantages over the traditional hay production in Kentucky. One advantage is it can be harvested, baled, and stored in a shorter period of time, …

Species And Variety Options For Baleage, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

Any forage species can be made into baleage or silage. While baleage is a form of silage, I’m defining it here as baled forage (typically round bales) that is wrapped in plastic (individually or in a line) for the ensiling process to take place. And silage is typically chopped forage that is ensiled in an upright or bunker silo or blown into a silage tube. The chopping mixes all the material together and allows tight packing to remove oxygen therefore encouraging faster fermentation. With baleage there is no chopping to mix the forage, so it’s essential that the forage is …

Introduction: The incidence of infective endocarditis (IE) in pregnancy is rare and has been increasing during the opioid epidemic. IE in pregnancy is associated with high rates of maternal and fetal morbidity and mortality. Multidisciplinary endocarditis teams for management of IE have been shown to reduce in-hospital and 1-year mortality. We present a single-center experience managing IE in pregnancy utilizing a multidisciplinary endocarditis team.

Methods: Patients diagnosed with IE while pregnant or within 30 days post-partum were identified. All patients discussed at the institution's weekly multidisciplinary endocarditis meeting were included. Demographic and clinical data and outcome-related variables were retrospectively reviewed …

Prevalence And Correlates Of Invitation To Participate In Clinical Trials Among Us Adults, Aurora Occa, Allison Leip, Allison S. Merritt, Jerod L. Stapleton

Communication Faculty Publications

Clinical trials are essential to modern medicine, but several barriers, including poor communication, hamper their successful completion. We examined the prevalence and correlates of invitation to participate in clinical trials among a nationally-representative sample of US adults using survey responses from the 2020 HINTS (Cycle 5). Analyses were conducted in 2021.

Overall, 9% of respondents reported being invited to a clinical trial, a prevalence that is nearly half of previously reported rates in convenience samples recruited from health care settings. Compared to non-Hispanic Whites, Black respondents reported the higher prevalence of invitation (16.0%) whereas Asian respondents reported the lowest (2%). …
