Use of Surveys, Field Demonstrations and Time Tapse Photography for Delivery of Forage Extension Information

It is often difficult to extend research information to forage producers in a format that they can understand and utilize. Over the last 10 years, University of Kentucky forage extension specialists have developed several effective extension tools to determine and show the effect of harvest and grazing height on Dactylis glomerata (L.) stand persistence and regrowth. D. glomerata is a widely planted forage species for hay and pasture in the USA based on its high productivity, forage quality and palatability (Lacefield and Ball, 2013)

Lessons Learned in Australia--UK Forages Study Tour

In September 2013, twenty Kentuckians traveled to Australia to tour farms and attend the International Grasslands Congress. The group included ten county agents, five farmers, four UK faculty/staff and a teacher. This study tour allowed participants to gain a new perspective of agriculture and how Australian farmers deal with adversity. Farmers there face many challenges each year with change in precipitation, ranging from severe drought to flooding. These challenges have forced them to incorporate different methods to be successful, including intensive grazing, use of overhead and drip irrigation for pasture and hay production, and fallow farming

The History of the International Grassland Congress 1927-2020

Grasslands cover 27% of the world’s land area and 70% of agricultural land. They form an important foundation for agriculture and livestock husbandry and contribute to the livelihoods of more than 800 million people. The International Grassland Congress (IGC) began as a meeting of a small group of forage researchers in Europe in 1927. It has now expanded into a gathering held every 3-5 years with over 1000 delegates from 80+ countries who represent research, extension, and primary production. The newly released IGC history provides not only an overview of the IGC Congress over the last 93 years, but highlights the people, events and changes in grassland agriculture around the world during this period. This current edition is an expansion and update of ‘A Brief History of the International Grassland Congress’ presented at the XX IGC in Ireland in 2005 by Professor Ross Humphreys, Australia. The authors have worked diligently to highlight the major individuals that shaped the IGC since its inception, including excerpts of presentations by world grassland leaders. They even included part of the welcome address from Prince Philip, Duke of Edinburgh, who was President of the XIII IGC held in Reading, United Kingdom, in 1960. The IGC History describes the two Congresses held in the United States, the XI IGC in State College, PA in 1952 and the XIV IGC in Lexington, KY in 1981. It also provides details on the formation of the Forage and Grassland Foundation by Dr. John Baylor and Mr. Warren Thompson (Kentucky) from the $100,000 profit of the XIV Congress

Master Grazer: Improving Grazing Management in Kentucky

The Master Grazer Educational Program is the result of funding provided by the Kentucky Agricultural Development Board to educate producers on better utilization of grazing lands to improve livestock production and the profitability of the State. County agriculture and natural resource agents, extension specialists, industry contacts and producers work together to make this program a success. The Master Grazer Educational Program began in 2006 as evening lecture sessions taking place in local extension offices. In 2008, the program grew with the addition of a field session that showcased a farm with successful grazing practices, a farm with underdeveloped grazing practices, and a final session for participants to develop their own grazing system. In 2010, the program was modified into the Applied Master Grazer Program. This program placed more emphasis on the importance of the county agriculture. The agents decided which topics would be covered and administered many areas of the program. The program now consists of a minimum of two evening field sessions in which a farm is showcased for a particular topic, as well as one impact session in which participants can interact and contribute to a producer forum. For the purpose of this article, reporting will be focused on the last two years of the Master Grazer Program. The past few years, events such as Grazing Schools, the Advanced Grazing Schools, and Pasture Walks have been held to discuss timely topics of forage and livestock management. Also, the Master Grazer Program has a newsletter, website, and DVD series

Lestaurtinib is a potent inhibitor of anaplastic thyroid cancer cell line models

Anaplastic thyroid cancer (ATC) is a rare and lethal human malignancy with no known effective therapies in the majority of cases. Despite the use of conventional treatments such as chemotherapy, radiation and surgical resection, this disease remains almost universally fatal. In the present study, we identified the JAK2 inhibitor Lestaurtinib as a potent compound when testing against 13 ATC cell lines. Lestaurtinib demonstrated a potent antiproliferative effect in vitro at nanomolar concentrations. Furthermore, Lestaurtinib impeded cell migration and the ability to form colonies from single cells using scratch-wound and colony formation assays, respectively. Flow cytometry was used for cell cycle analysis following drug treatment and demonstrated arrest at the G2/M phase of the cell cycle, indicative of a cytostatic effect. In vivo studies using the chick chorioallantoic membrane xenograft models demonstrated that treatment with Lestaurtinib resulted in a significant decrease in endpoint tumor volume and vascularity using power Doppler ultrasound imaging. Overall, this study provides evidence that Lestaurtinib is a potent antiproliferative agent with potential antiangiogenic activity that warrants further investigation as a targeted therapy for ATC

Developing a National Alfalfa Information System

Using state-of-the-art telecommunication technologies, this project is developing a comprehensive knowledge resource for alfalfa (Medicago sativa L.); the National Alfalfa Information System (NAIS). This project will serve as an improved model for Extension educational programs. Alfalfa is the most important forage crop in the USA and grown worldwide for feeding millions of livestock and in many cropping systems. As a legume, it is important in sustaining the environment and the productivity of agriculture. Information needs are present in every state and internationally. The NAIS is being developed through national and international cooperation, putting the best science-based alfalfa information and expertise at the fingertips of producers, consultants, extension workers, instructors, researchers, and users. Collaboratively developed materials will reduce duplication of effort. To make the knowledge easy-to-use, educational design, communication, and information science professionals are working with alfalfa experts in creating a WWW system and Web-aware CD-ROM. To ensure content quality, peer-review by members of multiple professional societies is included. A significant result will be around-the-clock availability of up-to-date, easy-to-use, and peerreviewed information. Shared workload and the peer-review process can influence faculty morale, efficiency, and effectiveness, an adjunct to maximizing the utilization of alfalfa worldwide by making the best information readily available
