Can I Afford To Spray For Weeds?, Scott Flynn

Kentucky Grazing Conference

A common question among managers of grazing operations is “At what level of weed pressure does it become economical to apply herbicides on pastures?” Unfortunately there isn’t just one answer to this question as production goals and practices differ between operations and even within an operation over time. Regardless, the real question being ask is if weed control will increase profit per acre.

Grazing Options For Fall And Winter, Edward N. Ballard

Kentucky Grazing Conference

Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation.

Summer Grazing Options, S. Ray Smith, Krista Lea

Kentucky Grazing Conference

During the last 15 years there have been several new forage species that have emerged as useful in grazing systems and many new varieties have been released of traditional species. There are many sources of information on summer grazing options. We especially encourage you to read the publication written by Dr. Garry Lacefield and colleagues, “Extending Grazing and Reducing Stored Feed Needs” (AGR-199, www.uky.edu/Ag/Forage/agr199.pdf). I have used information from this publication and other publications from the University of Kentucky Forage Website (www.uky.edu/Ag/Forage) in writing this article.

Technical Service Provider: What Is It And Why Is It Important To You?, Bill Payne

Kentucky Grazing Conference

Progressive graziers and forage managers are continually looking to improve their operations’ productivity. The opportunity exists to have a Grazing Management Plan developed for your operation at little or no cost to you. By contacting your county NRCS office, you can apply to have this plan developed by a Technical Service Provider, an independent professional certified by NRCS.

Forage Legumes: Their Importance And Management In Profitable Livestock Systems, Ben M. Goff

Kentucky Grazing Conference

The landscape of most Kentucky operations is heavily dominated by the utilization of cool-season grasses as the primary source of forage for livestock. However, legumes species, such alfalfa and red or white clovers are an essential component to a complete forage-livestock system. Relative to grasses alone, incorporating legumes into a mixture has the benefits of improving the nutritive value of the available forage in the field, extending the grazing season by increasing the yield of forage during the early summer months, and providing a more economical source of N compared to commercial fertilizers. This paper will briefly describe each of …

Maximizing Stocker Gains On Pastures, Jeff Lehmkuhler

Kentucky Grazing Conference

Stocker enterprises by definition utilize pasture forages to add weight to light weight feeder cattle. These operations add value to calves by assimilating small groups of calves and combining them into larger uniform packages. Stocker operators also enhance quality through livestock husbandry practices that “upgrade” feeders which could include castrating bulls, dehorning, improving immunity and other attributes. In an effort to optimize profit margins, stocker operators must manage feeders to ensure high rates of gain while finding a balance in stocking rates that provide adequate gains per acre.

Grazing Method: Tool Or Toolbox?, Garry D. Lacefield

Kentucky Grazing Conference

This conference makes the 15th consecutive year we have devoted a full day to Grazing. Kentucky is a great state for grazing animals since we have a relatively long pasture season, can grow many forage grasses and legumes and a long tradition of producing quality animal products from quality pasture. We have tremendous potential to improve our overall grazing efficiency and the discussion throughout the day will address many of the practical strategies for improvements.

Kentucky Water Resources Annual Symposium

This panel will discuss emerging findings from a US EPA-funded research project intended to improve risk communication for post-incident decontamination and clearance activities associated with intentional contamination of a water system. The session will center around Phase II of the study, which focuses on extending the Phase I case study findings that were presented at last year’s KWRRI Symposium, to identify ways in which disparate stakeholder groups in metropolitan areas differentially perceive risk and subsequent risk communication efforts.

Advances In Alfalfa Promotion, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Kentucky grain farmers have experienced several successful years seeing high prices and good yields, with the exception of the drought in 2012. If you were insured in 2012, which most lenders required, you probably also came out with a profit during that challenging time. Alfalfa producers in Kentucky have also seen high prices and decent yields. While the drought of 2012 affected them, most still harvested an 80 % crop with extremely high prices and demand. The fact that alfalfa is a deep rooted plant, coupled with timely rains proved beneficial to this group.

Why Aren't Big Square Balers Used More In Kentucky?, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

The history of making hay dates back for centuries and centuries. When mankind began to grow crops and livestock rather than being nomadic, they had to have some type of forage to feed their livestock during the cold and winter months. Since that time there has been a slow and steady progression from harvesting material by hand to today’s modern hay making equipment that maximizes time, labor, fuel, etc. However some countries to this day still use the methods that are thousands of years old when it comes to hay making.

Alfalfa For Summer Grazing, Roy Burris, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is most commonly used as a hay crop in the United States. However, with proper management, it can be utilized as a grazing crop with very good results. Liveweight gains per acre are quite high for grazing beef cattle with total season grains of 500 to 800 pounds per acre being reasonable. The authors realized 732 lb/acre of gains on 16 acres of alfalfa in 1991, with beef steers at Princeton.

Lessons Learned In Australia--Uk Forages Study Tour, Traci Missun, S. Ray Smith, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

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.

Alfalfa Baleage/Silage Preservatives: Do They Work? Are They Economical?, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are many variables with silage production including - type of silage operation (silo, bunk, tube, or wrapped bale), weather, packing or bale density, speed of covering. Therefore, no two silage crops are ever the same, which is why researchers are reluctant to give blanket statements regarding when and how to use silage inoculants. There has been a lot of good research though in recent years about the effect of silage inoculants under various management and conditions. What follows is an overview of this research and some general recommendations. Much of this overview was taken from a very good fact …

Role And Importance Of Alfalfa In Wku Teaching/Research/Farm Programs, Elmer Gray

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the oldest and most widely grown forage legume in the world and in Kentucky, where approximately 250,000 acres are produced. It has gained this top position through producing forage suitable for most classes of livestock, by being drought tolerant, and by fixing atmosphere nitrogen.
