PR-824: 2022 Cool-Season Grass Horse Grazing Tolerance Report

Jimmy Henning, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 14, 2022 (New)

Cool-season forages such as Kentucky bluegrass, tall fescue, and orchardgrass are dominant pasture grasses for horses in Kentucky. Variety evaluations for yield have been carried out for many years, but little work has been done to evaluate varieties of these grasses for persistence when subjected to close, continuous grazing by horses.

ASC-250: Reemergence of Bedbugs as Poultry Pests

Jacquie Jacob, Tony Pescatore | Dec. 2, 2022 (New)

It is estimated that one of every five Americans has had a bedbug infestation at home or knows someone who has. However, today bedbug infestations are not limited to just homes. Cage-free poultry houses have been found to have problems with bedbugs, and the incidence continues to rise. This makes bedbugs another important external parasite for which poultry producers need to be wary.

ASC-232: Raising Replacement Pullets for Small-Scale Egg Production

Jacquie Jacob, Tony Pescatore | Oct. 27, 2022 (Minor Revision)

Poultry producers who raise their own replacement pullets have better control over the growth, condition, and development of the flock. The quality of the pullet flock will have a direct effect on the subsequent level of egg production. The two most important quality factors for a replacement flock are proper body weight and uniformity. Pullet weight at 6 weeks of age has been shown to influence subsequent egg production. Once the pullets start to lay, it is too late to solve problems from poor nutrition or management during the pullet rearing period.

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.

ASC-248: Vitamin Supplementation for Beef Cattle

Les Anderson, Darrh Bullock, Kevin Laurent, Jeff Lehmkuhler, Katherine VanValin | Jul. 18, 2022 (New)

Beef cattle have defined requirements for vitamins. In some instances, vitamin supplementation may be necessary to avoid deficiencies. Vitamins are classified into two categories: water-soluble and fat-soluble. Water-soluble vitamins include the B vitamins, such as riboflavin, thiamin, and niacin, as well as vitamin C. Fat-soluble vitamins include vitamins A, D, E, and K. Supplementation for beef cattle generally focuses on vitamins A and E. This is because the rumen microbes synthesize the water-soluble vitamins and vitamin K in sufficient quantities to avoid deficiencies. Vitamin D requirements can often be met by exposure to the sun and would therefore only be of concern for cattle in confinement housing.

ASC-249: Reading the Fine Print: Understanding Mineral Tags

Jeff Lehmkuhler, Katherine VanValin | Jul. 18, 2022 (New)

Among the variety of supplementation options currently available for beef cattle operations, a mineral can be one of the most challenging to select. Mineral tags contain important information regarding the contents of a mineral supplement and are regulated by the Association of American Feed Control Officials (AAFCO). Understanding the information on a mineral tag will aid in the comparison of multiple products and help to ensure the selected mineral product will meet the needs of specific animals.

NEP-230: Cook Wild Kentucky: Fishing in Kentucky

Elizabeth Coots, Jann Knappage, Annhall Norris, Gregg Rentfrow, Matthew Springer, Jackie Walters, Martha Yount | May. 25, 2022 (New)

Kentucky offers some of the best fishing chances around. Among our rolling hills, you will find over 62,000 miles of fishable streams and 40 public lakes. Fishing is fun for all ages, and prime fishing spots can be found yearround across the state. Anglers take to the water each year for fun or food. Kentucky is home to bass, catfish, trout, sunfish, and more.

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.

PR-807: 2021 Cool-Season Grass Grazing Tolerance Report

Joao Costa, Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 7, 2021 (New)

Cool-season forages such as tall fescue, orchardgrass, and Kentucky bluegrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass and festulolium can also be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, perennial ryegrass, and other species when they are subjected to continuous, heavy grazing pressure by cattle within the growing season. Overgrazing is not a recommended practice, but is done in these studies to determine how different varieties perform under conditions that are worse than occur during the life of a typical pasture. Varieties are primarily rated for percent survival but data on seedling vigor and grazing preference are also presented.
