ASC-211: Expected Progeny Differences: Trait Definitions and Utilizing Percentile Tables

Sean Bessin, Darrh Bullock | Feb. 7, 2014 (New)

Expected progeny differences (EPDs) are useful tools in providing the best estimate of the genetic value of a particular animal as a parent. Differences in EPDs between parents of the same breed predict the performance differences of their future offspring if environmental factors are the same. EPD values should not be compared between breeds; for example, you should not compare an Angus bull's weaning weight EPD with a Simmental bull's weaning weight EPD. Most established breeds have EPDs for calving ease, growth, maternal, and carcass traits. When used properly, producers can make genetic improvements to their herd through parental selection. This publication is intended to help producers better understand EPDs and how one might use them in selection of replacement animals.

SR-105: 2012 Beef Research and Extension Report

Glen Aiken, Les Anderson, Darrh Bullock, Roy Burris, Lowell Bush, J.R. Bussard, Andrew Foote, Ben Goff, David Harmon, V.B. Holder, Isabelle Kagan, Nicole Kenney, D.H. Kim, S.E. Kitts, Jim Klotz, Anne Koontz, Jeff Lehmkuhler, Kyle McLeod, Jim Strickland, Eric Vanzant, Bill Witt | Jan. 7, 2014 (New)

The intent of this report is to provide highlights of our research and extension activities. We have a vested interest in the beef industry in the state and nation, and hope this report provides a window into our programs. We believe that after viewing this report, a greater appreciation will be garnered with respect to our involvement in the multiple fields of study related to beef production. The faculty, staff and student activities are advancing our understanding of basic science principles of livestock production as well as applied research that producers and the industry can benefit from immediately, as well as in the future. Extension educational programs, on-farm demonstrations, and other activities aid in transferring this knowledge to producers, allowing for increased awareness and adoption of management change.

ASC-205: Selecting Feeds for Horses

Fernanda Camargo, Laurie Lawrence | Jan. 6, 2014 (New)

Feeds should be selected with the nutrient requirements of the horse in mind, recognizing that requirements vary with the life stage of the horse (growing, pregnant, lactating, working, idle). Feeds for horses should always be clean and free from toxins. Feeds should also promote gastrointestinal health. The large intestine (cecum and colon) of the digestive tract contains a diverse population of beneficial microbes that can easily be upset by poor feed selection. In nature horses will spend more than 50% of their time grazing; therefore, feed that promotes similar feeding behavior may be desirable. Once appropriate feeds have been selected, it is important that they are fed in the correct amounts using good feeding management strategies.

PR-669: 2013 Cool-Season Grass Horse Grazing Tolerance Report

Garry Lacefield, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2013 (New)

Cool-season grasses such as 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 establish the effect of variety on persistence when subjected to close, continuous grazing by horses. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, and other species when subjected to continuous heavy grazing pressure by horses within the grazing season. The main focus will be on stand survival.

ASC-201: Avian Female Reproductive System

Jacquie Jacob, Tony Pescatore | Nov. 20, 2013 (New)

Anyone raising poultry for eggs, whether for eating or for incubation, should have an understanding of the reproductive system. This will help them understand any problems that may occur and how to correct them.

ASC-203: Avian Digestive System

Jacquie Jacob, Tony Pescatore | Nov. 20, 2013 (New)

An understanding of the avian digestive system is essential to developing an effective and economical feeding program for your poultry flock. Knowledge of avian anatomy, and what the parts normally look like, will also help you to recognize when something is wrong and take the necessary actions to correct the problem.

ASC-202: Avian Skeletal System

Jacquie Jacob, Tony Pescatore | Nov. 20, 2013 (New)

All animals have a skeleton to allow them to stand up and to protect their internal organs and tissues. The avian skeletal system looks similar to those of their mammalian counterparts, but there are some important differences.

ASC-204: Avian Muscular System

Jacquie Jacob, Tony Pescatore | Nov. 19, 2013 (New)

If you raise poultry for meat, it is always a good idea to have an understanding of the muscular system of poultry so you can better understand any problems that may occur and how to correct them.
