Inbreeding In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Inbreeding is broadly defined as the mating of individuals that are related. Strictly speaking, however, all animals within a breed are related. So, in a sense, every purebred sheep producer practices some degree of inbreeding. In most cases this relationship is very slight. Therefore, inbreeding is more practically defined as the mating of individuals more closely related than the average of the breed. This practice includes mating brother to sister, sire to daughter and son to dam.

Basic Sheep Genetics, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetics is the science of heredity. It seeks to explain differences and similarities exhibited by related individuals. The application of genetics to livestock improvement is known as animal breeding. The objective of this fact sheet is to provide a refresher course on basic genetics and to show how knowledge of genetics can be used to improve sheep production.

Keeping And Using Flock Performance Records, Debra K. Aaron

Agriculture and Natural Resources Publications

Performance records serve as the cornerstone of any good livestock management program. Unfortunately, the task of collecting, maintaining and using performance records is the one area of livestock production in general that gets the least attention. This fact sheet provides ten reasons why all sheep producers need to keep performance records on their flocks. Then, some ways of maintaining and using those records are discussed.

Crossbreeding Considerations In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Crossbreeding is the mating of individuals from different breeds. To a certain extent, it is a simple concept, but embarking upon a crossbreeding program, in sheep or any other livestock species, involves long-term decisions.

The primary benefits of a crossbreeding program are heterosis and breed complementarity.

Characteristics Of White-Tailed Deer Visits To Cattle Farms: Implications For Disease Transmission At The Wildlife-Livestock Interface, Are R. Berentsen, Ryan S. Miller, Regina Misiewicz, Jennifer L. Malmberg, Mike R. Dunbar

Zoonotics and Wildlife Disease: Publications

Bovine tuberculosis (bTB) is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in MI, USA. Currently, the rates of farm visitation by deer and co-use of forage resources by cattle and deer are poorly understood. To evaluate the extent deer and livestock may share forage resources, we investigated farm, yard, and cattle-use area visitation by white-tailed deer and compared visitation with common livestock management practices. We fitted 25 female white-tailed deer near the bTB-infected zone in Michigan’s Lower Peninsula with global positioning system collars. Livestock management practices associated with farm visitation included presence of confined feeding pastures, number of …

Diseases At The Livestock–Wildlife Interface: Status, Challenges, And Opportunities In The United States, Ryan S. Miller, Mathew L. Farnsworth, Jennifer L. Malmberg

Zoonotics and Wildlife Disease: Publications

In the last half century, significant attention has been given to animal diseases; however, our understanding of disease processes and how to manage them at the livestock–wildlife interface remains limited. In this study, we conduct a systematic review of the scientific literature to evaluate the status of diseases at the livestock–wildlife interface in the United States. Specifically, the goals of the literature review were three fold: first to evaluate domestic animal diseases currently found in the United States where wildlife may play a role; second to identify critical issues faced in managing these diseases at the livestock–wildlife interface; and third …

Animal Housing Legislation, Kelli Kirtley

Student Papers in Public Policy

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Brucellosis is the one of most common livestock zoonoses in Georgia, resulting in significant economic losses. Livestock were sampled in three regions of Georgia (Kakheti, Kvemo Kartli, Imereti). Districts that historically reported high numbers of brucellosis related morbidity were selected for serological, bacteriological and molecular surveys. Surveying efforts yielded samples from 10,819 large and small ruminants. In total, 735 serological tests were positive on Rose Bengal and 33 bacterial isolates were recovered and identified as Brucella melitensis or Brucella abortus by microbiology and AMOS-PCR. A Bayesian framework was implemented to estimate the true prevalence of the disease given an imperfect …

Managing Livestock Using Animal Behavior: Mixed Species Stocking And Flerds, D. M. Anderson, Ed L. Frederickson, R. E. Estell

Agriculture Faculty and Staff Scholarship

Mixed-species stocking can foster sound landscape management while offering economic and ecological advantages compared with mono-species stocking. Producers contemplating a mixed-species enterprise should reflect on several considerations before implementing this animal management strategy. Factors applicable to a particular producer's landscape must be considered together with goals and economic constraints before implementing mixed-species stocking. A major consideration when using mixed-species stocking is how to deal with predation losses, especially among small ruminants. An approach being adopted in some commercial operations capitalizes on using innate animal behaviors to form cohesive groups of two or more livestock species that consistently remain together under …

Changes In Hay Yield And Quality Of Bulbous Barley At Different Phenological Stages, Ferat Uzun

Turkish Journal of Agriculture and Forestry

The objective of this study was to determine the changes in hay yield and quality components at different phenological stages of a bulbous barley (Hordeum bulbosum L.) population handpicked from natural flora during 2003-2007 in Samsun, Turkey. The phenological stages of bulbous barley during spring-summer (grazing maturity, early heading, heading, and milk-dough) and autumn (early growing) were investigated. Significant differences were observed in hay yield, relative feed value (RFV), crude protein (CP), acid and neutral detergent fiber (ADF and NDF), Ca, Mg, K, P, Mn, Fe, and Zn concentrations, and K(Ca + Mg)^{-1} and Ca P^{-1} ratios of DM, depending …

Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema

Turkish Journal of Agriculture and Forestry

This paper briefly discusses global human requirements of protein nitrogen (N) from crops and animals, and then estimates the need for fertilizer N as a function of N use efficiency, and the recycling of N from animal manure and sewage wastes. These estimates are based on various assumptions and simple calculations. Results suggest that globally only 1% of N input is retained, 28% is lost to the wider environment, and some 70% is potentially available for recycling via manure and sewage. In addition, large amounts of nutrients recycle via crop residues. In practice, only a fraction of this potential is …

Evaluation Of Lifetimewool: 2008 National Farmer Survey Results, Anne Jones, Andrew Van Burgel, Gus Rose

All other publications

Key components of the lifetimewool evaluation plan were two National producer surveys to quantify change in the knowledge, attitudes, skills and aspirations over the duration of the project. In 2005, 2032 wool producers were surveyed to establish a benchmark for ewe and pasture management practices, knowledge and willingness to change. At that time, 93% of those who were surveyed said that they were willing to be resurveyed in 2008 at the completion of the project. This has allowed lifetimewool to compare individual producers’ changes in practices, knowledge and willingness over the three years that the communication and adoption phase of …

G05-1576 Safe Use Of Animal Medicines, Arden Wohlers, David R. Smith, Dicky D. Griffin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide promotes exercising caution while working with livestock medications.

Veterinary drugs, including antibiotics, antiparasite medications and vaccines, play an important role in the control and prevention of disease in all livestock. However, there is risk when working with animals and animal medicines. The United States Department of Agriculture (USDA), Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) have strict rules regulating the prescription, distribution and use of animal medications and chemicals. Regulations on how a drug is stored, administered, and disposed of ensure product safety to the producer, animal, consumer and environment.
