AEN-139: Kentucky Wind Directions and Magnitudes: A Tool for Siting Barns
Matthew Dixon, Morgan Hayes, Joshua Jackson | May. 13, 2019 (New)
Wind is variable in time and space. This is especially true across the state of Kentucky, considering the geographical variety from the Eastern Kentucky mountains to the flatter grain production region in Western Kentucky. In particular, there is a region of potentially variable wind around Cincinnati, near the Ohio River. In trying to account for this variability, monthly wind maps across the state of Kentucky have been developed using the past 30 years of recorded wind data. These data can be used to assist in site evaluations for barns and planning farmstead layouts. Knowing wind speed and direction will help optimize the natural ventilation taking place within agricultural buildings.
AEN-138: Protecting Pastured Cattle using Windbreaks and Mounds
Steve Higgins, Lee Moser | Apr. 10, 2019 (New)
Research shows that cattle benefit from summer shade and winter shelter. Pastured cattle seek shelter around structures, under trees, and in forested streamside zones. These areas are often heavily trafficked and become muddy, compacted loafing areas. Mud creates further stress on cattle and compounds the problems of temperature stress and feed inefficiencies. One option that could be used to lure cattle from these areas and provide winter shelter and summer shade is a constructed windbreak fence on a mound.
AEN-137: Farm Gates: Design Considerations
Steve Higgins, Lee Moser | Feb. 18, 2019 (New)
Farm gates are a necessity for controlling traffic and increasing security. There are many design considerations for optimizing a system of farm gates. Very few gates incorporate all the recommended design components that will be discussed in this publication. However, to move people, materials, equipment, and livestock through a gateway, the gateway should economize time, be navigable, and operate in an efficient manner. Time spent operating a poorly designed gateway is time wasted and a hindrance to production. This publication is a guide to aid producers in creating more functional designs for gateways.
AEN-136: Fence Line Stiles, Escapes, and Refuges
Steve Higgins, Michele McHugh, Lee Moser | Jan. 23, 2019 (New)
Opening farm gates for trucks, tractors, equipment, and livestock is unavoidable. However, opening a large gate, or a set of gates, for a person on foot is extremely inefficient, especially if the entrance does not put the producer where they need to be. An inconveniently located gate can lead to additional steps and unnecessary movements. Opening gates may require dealing with clasps, chains, or ropes just to get the gate unfastened. The gate may then have to be lifted or dragged open and closed. The bottom-line is that entering a poorly installed and unmaintained gateway can make the experience of opening and closing gates a time consuming nuisance.
ID-249: A Comprehensive Guide to Soybean Management in Kentucky
Ric Bessin, Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Carrie Knott, Chad Lee, Travis Legleiter, Josh McGrath, Sam McNeill, Javier Reyes, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Claire Venard, Raul Villanueva, Ole Wendroth, Kiersten Wise, Xi Zhang | Jun. 7, 2018 (New)
This publication provides information on soybean growth and development, principles of variety selection, and management practices to maximize soybean profitability in Kentucky.
AGR-236: Managing Frost Damaged Alfalfa Stands
Matthew Dixon, Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch | Mar. 19, 2018 (New)
Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.
AEN-135: Rainwater Harvesting for Livestock Production Systems
Steve Higgins, Lee Moser | Nov. 7, 2017 (New)
Abundant, clean drinking water is an essential nutrient for livestock. The obvious water source that is recommended by veterinarians is city water. However, city water has its drawbacks. City water distribution systems are often expensive to install and have a recurring usage charge. In some instances, city water is unavailable, may have inadequate pressure, or producers consider it too expensive to operate, forcing them to use streams and ponds to water livestock. Collecting rainwater from a catchment area, is a low cost, high quality alternative water source that can supplement traditional water distribution systems and improve the environmental quality of farming operations. Rainwater harvesting involves the collection of rainfall from rooftops or land based catchments systems for storage and distribution as needed. Capturing rainfall has the added benefit of improving water quality by reducing soil erosion and runoff. Strategically installed rainwater harvesting systems can be used to direct stormwater around sensitive areas of the farm where animal waste is present, thus reducing the potential for nutrient and pathogen delivery to nearby waterways. Rainwater harvesting and stormwater management techniques can also reduce the volume of water that must be managed in liquid manure management systems by diverting clean water away from manure pits and lagoons.
AEN-115: Appropriate All-Weather Surfaces for Livestock
Steve Higgins, Stephanie Mehlhope, Lee Moser, Sarah Wightman | Oct. 16, 2017 (Minor Revision)
Many livestock producers would say that mud is a natural part of livestock production. But the creation of mud costs producers money and makes them less competitive. Livestock that walk through mud require more feed for energy but actually eat less because walking in mud requires more effort to get to feed and water. Therefore, mud decreases average daily gains. Mud accumulation on the coat increases the amount of energy needed to generate heat in the winter or to keep cool in the summer. Also, it can lower sale prices due to hanging tags. The creation of mud also increases animal stress and leads to a variety of health problems, including protozoan and bacterial infections. It is essential that livestock producers understand that mud hinders cost-efficient livestock production and efforts should be made to limit the creation of mud. This publication explains how mud is created and describes different types of hardened surfaces and pads that agricultural producers should use to reduce mud creation and ultimately increase production efficiency and protect natural resources.
AEN-133: Tire Tanks for Watering Livestock
Carmen Agouridis, Steve Higgins, Joshua Jackson, Lee Moser | Aug. 8, 2017 (New)
Kentucky's abundant forage and extensive stream system have helped the Commonwealth become the largest beef producing state east of the Mississippi River. While streams and ponds serve as a water source for many operations, livestock can quickly degrade soil and water quality by trampling streambanks and defecating and urinating in and around waterbodies. These actions increase sediment, pathogen, and nutrient loads to streams, rivers, and lakes which in turn can causes eutrophication. To help protect the health of Kentucky's soil and water, producers can implement best management practices (BMPs). These practices help reduce the sources of pollutants and/or the transport of pollutants to waterways. One such practice or BMP is limiting cattle access to streams and ponds. When producers exclude livestock access to stream and ponds and their associated riparian buffers, an alternative source of water is required. Automatic water fountains are one commonly used means of providing cattle with water from an alternate source. A water tank constructed using a heavy equipment tire may serve as a viable option for supplying livestock with an alternate source of water.
ID-246: Measuring the Ph of Different Food Products
Akinbode Adedeji, Paul Vijayakumar | Jul. 21, 2017 (New)
The scientific scale for measuring how acidic or basic a substance is when it is dissolved in water is called pH. The pH scale runs from 0 - 14. 0 means it is very acidic, 7 means it is neither acidic nor basic, but just right in the middle like plain water (neutral), and 14 means it is very basic. If you are producing a food product that depends on the acidic components or ingredients of the product to extend its shelf life and ensure the safety of the product, monitoring the pH of food products is very important. Food safety is the biggest reason for monitoring pH, but pH also influences the quality of food products.
