Mystery Mutt: Dna Analysis With A Dog Named Charlie, Kelly M. Jones

Inclusive Strategies for Teaching Secondary Mathematics and Science

This article provides an in-depth exploration of the design, execution, and outcomes of the "Mystery Mutt: DNA analysis with a dog named Charlie" lesson. Designed for seventh-grade life science students, the lesson focuses on unraveling the correlation between genotype and phenotype using authentic pet DNA test results. Grounded in real-life experiences and employing a multi-dimensional approach, the lesson successfully bridges the gap between theoretical genetic concepts and practical applications. The article discusses the lesson's alignment with academic standards, consideration of materials and safety, its unique classroom context, and the engaging phases of exploration, explanation, elaboration, evaluation, and closure. The emphasis …

G09-1856 Commercially Available Dna Tests For Genetic Improvement Of Beef Cattle, Matthew L. Spangler

University of Nebraska-Lincoln Extension: Historical Materials

Misinterpreting DNA tests can cost beef cattle producers time and money. This 2009 NebGuide discusses how to interpret commercial DNA marker tests.

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.

Nf99-403 Livestock Waste Management Act (Revised March 2001), J. David Aiken

University of Nebraska-Lincoln Extension: Historical Materials

The Livestock Waste Management Act requires all livestock operations with 300 animal units or more to be inspected by the Nebraska Department of Environmental Quality (DEQ) to determine whether livestock wastes contaminate surface or ground water. This NebFact discusses the following parts of the Livestock Waste Management Act: Act (how cited); Terms (defined); Livestock operation, exemption, livestock waste control facility, permit, restriction; Construction permit or operating permit (when required), livestock waste control facilities, classification, restrictions; Section (how construed); Cold water class A streams (designation); Permit (acknowledgment required); Livestock operation (request inspection, when, fees, department, duties); Permits (duration, modification); Permit (application …

This NebFact offers the text of the Nebraska Competitive Livestock Markets Act.

G98-1370 Abandonment Planning For Earthen Manure Storages, Holding Ponds And Anaerobic Lagoons, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this NebGuide is to define some critical issues to be addressed by an abandonment plan of an earthen manure storage, anaerobic lagoon or runoff holding pond.

A Nebraska construction permit for a Livestock Waste Control Facility (LWCF) requires a written plan defining possible abandonment procedures in the event the operation (and associated LWCF) is discontinued. The plan must be approved by the Nebraska Department of Environmental Quality (NDEQ) prior to permit issuance.

Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska has an abundance of crop residue available for late fall and winter grazing. However, several factors prevent the grazing of many fields, including the location of fields in relation to the cattle, the lack of shelter or appropriate fencing and water availability. Despite these limitations, residue grazing is an important resource to many cattle operations, primarily as either a winter feed resource for maintaining the breeding herd or putting weight on cull cows. Calves weaned in the fall can also be wintered on cornstalks if appropriate supplementation is used.

Rp94-529 Porcine Somatotropin (Pst), Palmer J. Holden

University of Nebraska-Lincoln Extension: Historical Materials

What is porcine somatotropin (pST)?

Porcine somatotropin, abbreviated as pST, is a growth hormone naturally produced in pigs. The word "porcine" refers to pigs, and the word "somatotropin" means body growth and refers to the name of the hormones.

This research publication discusses what porcine somatotropin is, how scientists developed pST, how the protein nature affects its use, what research shows, is pST safe and will consumers accept it, and what is pST's future.

Nf92-63 Cholesterol In Your Blood, Harriet Kohn, Linda S. Boeckner

University of Nebraska-Lincoln Extension: Historical Materials

This NebFact discusses blood cholesterol.

Ec91-123 Drought Management On Range And Pastureland: A Handbook For Nebraska And South Dakota, Patrick E. Reece, Jack D. Alexander, James R. Johnson

University of Nebraska-Lincoln Extension: Historical Materials

Drought is generally defined as a prolonged period during which annual precipitation is less than 75 percent of average. Based upon this definition, drought has occurred in 21 percent of the years in the northern Great Plains since 1940. Poor distribution of precipitation in a single year or less than average precipitation in successive years can also cause drought conditions.

This extension circulation discusses the following: how plants respond to drought, management preparation for drought, herd management, animal response to drought, predicting forage production and stocking rates, drought management plans, rangeland resource inventory, grazing management, and plant recovery after drought.

G76-279 Processing Deer, Glenn W. Froning, P. S. Gipson

University of Nebraska-Lincoln Extension: Historical Materials

It is important to process game properly to obtain maximum flavor and storage stability.

It is a pleasure to hunt game, but perhaps an even greater satisfaction comes from eating the meat. In order to have a flavorful experience, the game animal must be handled, processed and prepared properly. If the game is improperly processed or handled, one may lose much of the desirable flavor and storage stability.

Ec25-228 Farm Slaughter Of Hogs, Wm. J. Loeffel

University of Nebraska-Lincoln Extension: Historical Materials

Slaughtering hogs and curing the meat on the farm is a common practice which makes available a palatable and nutritious food. It utilizes labor at a season of the year when usually there is no great rush of work.

As a general rule, farm slaughter is not to be recommended until cold weather is a certainty, for warm weather is apt to cause heavy spoilage. Meat is a highly perishable food product, therefore absolute cleanliness should prevail in its handling. Contamination of meat by soiled hands, clothing, tools, or containers is not only insanitary but actually lowers the keeping quality …
