Additionally, the fourth infographic gives some insight into why forage is a staple in the equine diet based on the digestive system.

All four infographics have been posted to the University of Nebraska-Lincoln’s Horse Program social media pages in an …

Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello

Honors Scholar Theses

Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …

Fetal Programming Of Intrauterine Growth Restricted Skeletal Muscle Stem Cell Function, Micah Most

Honors Theses

Intrauterine growth restriction (IUGR) reduces skeletal muscle mass in fetuses and offspring. The objective of this study was to determine if myoblasts (skeletal muscle stem cells) from maternal inflammation induced intrauterine growth-restricted (MI-IUGR) fetuses are less responsive to proliferation-stimulating factors in culture. Ovine MI-IUGR fetal myoblasts were isolated at 125 days of gestational age (dGA, term = 150 dGA), grown for 72 hours in complete growth media spiked with insulin, tumor necrosis factor α (TNFα), or unspiked (basal), and analyzed for ex vivo proliferative capacity via a 2 hour EdU pulse. A second set of myoblasts were differentiated in differentiation …

Animal-Assisted Activities Survey At The University Of Nebraska-Lincoln: Assessing Student Opinions And Determining Possible Implementation Strategy, Emma Winters

Honors Theses

In most situations, animals are not allowed on the University of Nebraska-Lincoln (UNL) campus, including animals used for animal-assisted activities (AAA). Animal-assisted activities have been shown to provide numerous benefits to participants and there could be positive effects to offering AAA at UNL. In order to gauge the opinions of students regarding AAA and how AAA could best be implemented on the UNL campus, a survey was emailed to Animal Science majors and students enrolled in ASCI 271 and ASCI 321 at the University of Nebraska-Lincoln.

G05-1587 Understandng Effective Fiber In Rations For Dairy Cattle, Paul J. Kononoff

University of Nebraska-Lincoln Extension: Historical Materials

Fiber type, quality and length are key to herd health and production.

Fiber is a key component in dairy rations. When nutritionists are faced with herd challenges such as low milkfat tests, foot problems, or low feed conversions, ration fiber often is evaluated. Effective fiber depends on the type and amount of forages and nonforage fiber sources being fed, the particle size of those forages and the amount of available nonfiberous carbohydrates included in the diet.

Ec05-185 Grazing Winter Wheat In Nebraska, Tom Holman, Drew J. Lyon, David D. Baltensperger, Ivan G. Rush, Ray Weed

University of Nebraska-Lincoln Extension: Historical Materials

Grazing cattle on winter wheat, often prior to grain harvest, is common throughout the southern Great Plains. Grazing generates about $50 million in income for Texas wheat producers and reduces the risk of growing wheat by providing a substantial income source other than grain. Benefits can be realized by grazing prior to the primary environmental risk period for drought, heat stress, and hail, all of which frequently reduce grain yield while having limited impact on forage production. Cattle also are grazed on winter wheat fields in western Nebraska and the surrounding region. Typically in Nebraska, fall forage would be used …

Rp 357 Quality And Yield Grades For Beef Carcasses, Dennis E. Burson

University of Nebraska-Lincoln Extension: Historical Materials

There are two types of beef grades in the United States--quality grades and yield grades. Beef carcasses may carry a quality grade, a yield grade or both a quality and yield grade.

Quality grades indicate expected palatability or eating satisfaction of the meat; yield grades are estimates of the percentage of boneless, closely trimmed retail cuts from the round, Join, rib and chuck.

Federal meat grading is a voluntary service packers request and pay for on an hourly fee basis. Meat grading should not be confused with meat inspection, which is mandatory and ensures the safety and wholesomeness of our …

Ec00-280 Hiring Dairy Personnel: Making The Process Easier, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Position descriptions are essential. A detailed position, or job, description can help you as an employer identify and eliminate applicants who will not perform well on the job and gives you justifiable grounds for terminating an employee who does not perform the job satisfactorily.

On most dairy farms, employees can be grouped into three categories: herd managers, feeders or outdoor workers, and milkers. This extension circular discusses the description for each category, how to start the hiring process, and questions that may be asked during interviewing and after hiring for a position on the dairy farm.

G98-1350 Basics Of Feeding Horses: What To Feed And Why, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the horse's digestive system and appropriate feeding procedures.

Because of the horse's eating habits and digestive system, feeding practices common to other species of livestock often result in severe digestive dysfunction or even death for the horse. In fact, several anatomical peculiarities of the horse's digestive tract predispose horses to digestive disorders such as colic and laminitis even under the best management. Under poor feeding management, the onset of these disorders is almost assured. The objective of feeding management is to provide a ration with balanced nutrition that both maximizes nutrient utilization while minimizing the occurrence of …

Ec97-275 Effect Of Lactation Length On Sow Reproductive Performance, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

As lactation length decreases there is an increase in the weaning-to-estrus interval, a decrease in farrowing rate, a decrease in subsequent litter size and an increase in pigs weaned per sow per year. Because of herd-to-herd differences in the influence of lactation length on reproductive performance, each farm should conduct a preliminary study to evaluate the effect of the lactation length being considered before implementing the “new” weaning age of piglets.

Ec97-276 Management Strategies For Pen-Mating Female Pigs, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

The master control switch of a pork production enterprise is weaning day. Pork production managers have little or no control concerning when a weaned female will cycle or how long she will be in estrus after weaning. When females are pen-mated, the producer needs to use management procedures to prevent an excessive number of estrous females from expressing the standing response at the same time, try to manage estrous females so that they are bred at the proper time, try to manage boars so they maintain an adequate level of fertility, evaluate boars for level of sexual behavior before and …

Ec97-274 Management Of Replacement Gilts For Efficient Reproduction, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

Successfully introducing replacement gilts into the breeding herd is an important aspect of breeding herd efficiency. To attain herd efficiency, females must ovulate adequate numbers of viable ova, express estrus, show willingness to mate and conceive in a regular manner. If these qualities are properly developed, pregnancy rate and litter size will be maximized. A gilt development and management program needs to be designed for gilts from birth to farrowing their first litter.

G97-1324 Beef Cattle Implant Update, Dicky D. Griffin, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the mechanism of action and use strategies for growth promoting implants, including expected responses and cost analysis.

Introduction

Growth promoting implants have been used extensively in beef production for over 30 years. Significant changes in implants and implanting strategies have occurred. Prior to 1987, available implants were estrogenic agents which metabolically enhanced nutrient use to enhance growth. These products improved feed efficiency 5-10 percent and daily gains from 5-15 percent. In 1987, the androgenic (tissue building) agent, trenbolone acetate, was approved for use in growth promoting implants. This compound had an additive effect with existing estrogenic implants. …
