ID-273: Match-a-Yak: a Tool to Minimize Inbreeding in North American Yaks
Les Anderson, Darrh Bullock, Ted Kalbfleisch, Jeff Lehmkuhler, Mary McCarty | Sep. 25, 2023 (New)
The domesticated yak (Bos grunniens) arrived in North America in the late 1890s. A few animals were imported into Canada and North American zoos and became the foundation of the North American genetic pool. Research was conducted in Alaska hybridizing them with Highland cattle in the early 1900s. A handful of yaks were imported into the United States in the early 1900s and again later in the 1980s. However, the genetic diversity of the North American yak is limited, necessitating a need to manage breeding programs to reduce inbreeding.
ID-1: The Kentucky Extension Master Gardener Program
Sharon Bale, Tom Barnes, Jessica Bessin, Kenneth Clayton, Rick Durham, Bill Fountain, J.D. Green, Kelly Jackson, Krista Jacobsen, Jonathan Larson, Brad Lee, Kimberly Leonberger, Adam Leonberger, Gregg Munshaw, A.J. Powell, Edwin Ritchey, Rachel Rudolph, Robbie Smith, Matthew Springer, Lee Townsend, Nicole Gauthier, Stacy White, Mark Williams, Erica Wood, Shawn Wright | Aug. 24, 2023 (New)
Plants are essential to life on earth. Either directly or indirectly, they are the primary food source for humans and other animals. Additionally, they provide fuel, replenish the earth's oxygen supply, prevent soil erosion, slow down wind movement, cool the atmosphere, provide wildlife habitat, supply medicinal compounds, and beautify our surroundings.
ID-172: An IPM Scouting Guide for Common Pests of Solanaceous Crops in Kentucky
Ric Bessin, Nicole Gauthier, Rachel Rudolph, Shawn Wright | Aug. 14, 2023 (Minor Revision)
Proper identification of pathogens and insect pests as well as nutritional and physiologic disorders and even herbicide drift is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter when producing solanaceous crops (tomatoes, peppers, eggplant, and potatoes) in Kentucky.
ID-274: Economic Efficiency in Organic Dairy Operations
John Allison, Kenny Burdine, Ray Smith | Apr. 3, 2023 (New)
Organic dairy operations have historically commanded a higher milk price than conventional dairy operations (Organic all milk price 2021 average: $31.55 per hundredweight (USDA AMS, 2021), Conventional all milk price 2021 average: $20.25 per hundredweight (USDA ERS, 2021)). However, the economics of decision-making and management still play a pivotal role in farm profitability.
ID-123: Livestock Waste Sampling and Testing
Doug Overhults, Monroe Rasnake | Mar. 13, 2023 (Revised)
It is estimated that about 25 million tons of animal manure are currently produced on Kentucky farms each year. Most of this is deposited by grazing animals on pastures where the nutrients are recycled. However, an increasing percentage is accumulated in feed lots, barns, poultry houses, lagoons, and other facilities until it can be spread on the land.
ID-199: Prechilling Switchgrass Seed on Farm to Break Dormancy
Holly Boyd, Cindy Finneseth, Tom Keene, Laura Schwer, Ray Smith | Mar. 13, 2023 (Revised)
Switchgrass (Panicum virgatum L.) is a warm-season, perennial bunch-type grass native to the North American Tallgrass Prairie. It has been investigated as a renewable energy crop due to its high productivity across a wide geographic range including various environmental conditions and soil types. Switchgrass has also been used for erosion control, summer grazing in pasture and hay systems for cattle, native prairie restoration, wildlife habitat, fiber production, and as an ornamental grass.
ID-139: A Comprehensive Guide to Corn Management in Kentucky
Carl Bradley, J.D. Green, John Grove, Greg Halich, Erin Haramoto, Cam Kenimer, Carrie Knott, Chad Lee, Travis Legleiter, Sam McNeill, Michael Montross, Hanna Poffenbarger, Dan Quinn, Edwin Ritchey, Montse Salmeron, Jordan Shockley, Tim Stombaugh, Raul Villanueva, Ole Wendroth, Kiersten Wise | Dec. 13, 2022 (Major Revision)
Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.
ID-217: Forage-Related Disorders in Cattle: Nitrate Poisoning
Michelle Arnold, Jeff Lehmkuhler, Megan Romano, Ray Smith | Oct. 24, 2022 (Minor Revision)
Nitrates are natural constituents of all plants. Under normal conditions, plants take up nitrate through their roots and transport it to the leaves for use in photosynthesis. However, photosynthesis decreases under adverse environmental conditions (e.g., drought; leaf damage due to disease, hail, frost, insects, or herbicides; cool and cloudy weather; and other plant stressors). When photosynthesis is reduced, nitrate transportation to the leaves slows also. Potentially toxic nitrate concentrations can remain in the lower stalks and stems.
ID-2: Guide to Plants of Kentucky Potentially Poisonous to Livestock
Michelle Arnold, J.D. Green, Megan Romano | Apr. 22, 2022 (Minor Revision)
Poisonous plants are responsible for considerable losses to farmers and stockmen in Kentucky. Many cases of plant poisoning are never diagnosed or even suspected. There are nearly 100 different species of plants growing in Kentucky that under certain conditions may be poisonous to livestock, although only one third of these are likely to cause serious trouble. The primary purpose of this publication is to enable individuals to recognize, at sight, some plants which are known to be dangerously poisonous, and to have knowledge of those additional plants, which, under certain conditions, may cause trouble.
ID-196: UK Ag Equine Programs Calendar, 2022
Bob Coleman | Dec. 9, 2021 (Minor Revision)
The information in this calendar is provided to aid owners in planning for the care and use of their horses. When necessary, information is discussed in the month prior to application to allow horse owners adequate time to plan for activities such as weed control, soil testing, and vaccinations. Contact your local veterinarian for health-related issues and your county extension agent for further information.
