Grass-finished beef (GFB) can provide beneficial bioactive compounds to healthy diets, including omega-3 polyunsaturated fatty acids (n-3 PUFAs), conjugated linoleic acid (CLA), and secondary bioactive compounds, such as phytochemicals. The objective of this study was to compare fatty acids (FAs), micronutrients, and phytochemicals of beef fed a biodiverse pasture (GRASS), a total mixed ration (GRAIN), or a total mixed ration with 5% grapeseed extract (GRAPE). This was a two-year study involving fifty-four Red Angus steers (n = 54). GFB contained higher levels of n-3 PUFAs, vitamin E, iron, zinc, stachydrine, hippuric acid, citric acid, and succinic …
A Mechanistic Examination Of Interspecific Competition Between Wild And Domestic Herbivores, Courtney Check
A Mechanistic Examination Of Interspecific Competition Between Wild And Domestic Herbivores, Courtney Check
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Large herbivores, such as mule deer and cattle have similar life histories and likely compete for resources. However, quantifying the extent to which these species compete and the specific resources they compete for has proved challenging. My research examines if cattle influence deer abundance and behavior due to competition for forage, competition for shade, and/or by affecting the predation risk of deer. Using a grid of autonomous trail cameras, I was able to determine if cattle abundance influences local deer abundance in relation to specific resources and habitat features. Using GPS data from collared deer, I was also able to …

Estimating Cattle Density Using Wildlife Cameras, Emily Bonebrake
Undergraduate Honors Capstone Projects
Quantifying the abundance and distribution of animal populations is critical for effective wildlife research and management. Due to their cost-effectiveness, wildlife cameras have become an increasingly popular tool for estimating population densities. Previously, this technique relied on ‘capture-recapture’ models that utilized re-sightings of individually marked animals, but in recent years methods have been developed to estimate the population densities of unmarked animals. One such method is the random encounter and staying time (REST) technique, which does this by assuming that the cumulative time animals stay within the view of the camera scales linearly with the number of individuals. This allows …

Effects Of Providing Novel Feedstuffs To Livestock On Production And Skeletal Muscle Growth, Laura A. Motsinger
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As the population increases and available land for food production decreases, it is necessary for livestock producers to continually work towards increasing livestock production efficiency. In livestock operations, feed accounts for the majority of input costs associated with raising livestock. As such, it is necessary to improve growth and production of livestock animals, while also optimizing feed utilization. Different feedstuffs can be included in the diet of livestock animals to maximize growth and production. However, the effects of some of these novel feedstuffs on growth and production of livestock animals has not been elucidated. As such, we investigated the effects …

Human–Wildlife Interactions
Domestic livestock grazing is the dominant land use on much of the current range inhabited by greater sage-grouse (Centrocercus urophasianus; sage-grouse) in the western United States. Nonnative feral horses (Equus ferus caballus) also inhabit important sage-grouse seasonal habitats. Overabundant feral horse populations and improper grazing by domestic cattle (Bos taurus) can impact the health of sagebrush (Artemisia spp.) and desert shrub rangeland communities and native wildlife. These impacts to sage-grouse can be exacerbated when they affect late brood-rearing habitat, which provide the forbs and arthropods required to fledge broods. Managers require better information …

Demographics, Accuracy, And Impact Of Feed Laboratories In The United States, Jerald H. Severe
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Feed analysis is very important to modern society. In the United States feed analysis is used to optimize production of food animals. Feed analysis is also used as a tool to place value on crops. As important as feed analysis is to society, little research has been done that describes which feed laboratories are the most popular and why people use them. It has been thought by some patrons that different results from the same feed sample are obtained by different laboratories. Is this true? If so, what is the effect on those that use feed laboratories to produce animals, …

Livestock Preference For Endophyte-Infected Or Endophyte-Free Oxytropis Sericea, Ipomoea Carnea, And Ipomoea Asarifolia, James Pfister, Daniel Cook, Stephen T. Lee, Dale R. Gardner, Franklin Riet-Correa
Poisonous Plant Research (PPR)
Fungal endophyte-infected forages have been shown to alter herbivore feeding preferences. The objective of this experiment was to compare the preference of cattle, sheep, and goats for plants containing (E+) and not containing (E-) fungal endophytes using freshly harvested Oxytropis sericea, Ipomoea carnea, and Ipomoea asarifolia. Goats and sheep rejected all forage choices regardless of endophyte status except for grass and alfalfa hay. Endophyte status had no influence on cattle forage preferences. Cattle rejected all Oxytropis sericea E+ and E- choices. Cattle discriminated between Ipomoea species, preferring Ipomoea carnea to Ipomoea asarifolia (P = 0.004). In all …

Medication Darts Are Gaining In Popularity - Do They Affect Meat Quality? Are There Risks?, David J. Wilson, Kerry A. Rood
All Current Publications
Livestock, such as beef cattle or post-weaned dairy cattle that are not yet milking, are often relatively “tame” (sometimes the term tame may not apply very well) and can be readily approached within a few feet. However, without adequate restraint facilities or enough personnel, actually treating the livestock is often difficult and can become frustrating and dangerous to people and animals. A solution to this problem, which is being rapidly and increasingly adopted, is the use of medication darts. Nevertheless, many in the cattle industry are raising some concerns. What are some of the characteristics of medication darts? Is there …

Effects Of Livestock Grazing Management Practices On Greater Sage-Grouse Nest And Female Survival, Seth J. Dettenmaier
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The decline in greater sage-grouse (Centrocercus urophasianus; sage-grouse) populations across western North America has been primarily attributed to loss and fragmentation of their sagebrush (Artemisia spp.) habitats. This habitat loss is largely the result of increased human activities, with grazing by domestic livestock as the most predominant land use across the sagebrush ecosystem in North America. The goal of my research was to increase our understanding of the effects of livestock on sage-grouse populations. I reviewed the peer-reviewed literature for all published studies that reported potential effects of grazing on grouse species worldwide. I found that there …
Managing Dietary Protein In Cattle As A Means Of Reducing Ammonia Emissions To Improve Air Quality, Ashley Houston
Managing Dietary Protein In Cattle As A Means Of Reducing Ammonia Emissions To Improve Air Quality, Ashley Houston
Undergraduate Honors Capstone Projects
Particulate matter pollution has become a subject of great concern across the globe. Emissions data has revealed that the agricultural sector is making large contributions to particulate matter through ammonia emissions. Beef and dairy cattle are responsible for producing nearly 50% of annual ammonia emissions in the United States. These animals are often fed amounts of dietary protein that exceed recommendations, resulting in increased excretion of urea and ammonia. These compounds combine with nitrogen oxides in the atmosphere to form PM2.5: particulate matter measuring less than 2.5 microns in diameter. Research has shown that through proper dietary management …

This paper investigates spatial, quality and temporal factors impacting the pricing of calves and yearlings in the western United States using data from a satellite video auction and a hedonic regression framework. Results suggest that spatial price discounts received by western ranchers closely match reported shipping costs and, thus, are consistent with free-on-board pricing and competitive procurement. This study also identifies the presence of temporal price premiums, on average, for seller-offered forward contracts at video auctions. With respect to quality attributes, this study provides estimates of the marginal value associated with various quality attributes and management practices, including vaccination protocols, …

Animal, Dairy, and Veterinary Science Faculty Publications
Trophoblast cells from bovine somatic cell nuclear transfer (SCNT) conceptuses express major histocompatibility complex class I (MHC-I) proteins early in gestation, and this may be one cause of the significant first-trimester embryonic mortality observed in these pregnancies. MHC-I homozygous-compatible (n = 9), homozygous-incompatible (n = 8), and heterozygous-incompatible (n = 5) SCNT pregnancies were established. The control group consisted of eight pregnancies produced by artificial insemination. Uterine and placental samples were collected on Day 35 ± 1 of pregnancy, and expression of MHC-I, leukocyte markers, and cytokines were examined by immunohistochemistry. Trophoblast cells from all SCNT pregnancies expressed MHC-I, while …

Effects Of Condensed Tannins On The Toxicity Of Fireweed (Senecio Madagascariensis) To Cattle, Carolyn L. Wong
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Fireweed (Senecio madagascariensis) is a noxious and invasive weed affecting pastures in Hawaii, Australia, and South America. Fireweed contains compounds called pyrrolizidine alkaloids that are toxic to most grazing mammals. Toxic effects to cattle include irreversible damage to liver cells, hardening of the liver, and loss of liver function, which may lead to jaundice, swelling, and the accumulation of fluids in the stomach and other physiological malfunctions. External effects include rough appearance, diarrhea, low energy and dullness, photosensitization, and abnormal behavior, many of which can lead to death. Fireweed also can reduce pasture productivity by as much as …

Animal, Dairy, and Veterinary Science Faculty Publications
Historically, the most significant losses from halogeton poisoning have been reported in sheep, with multiple catastrophic deaths documented. While recorded death losses in cattle from halogeton poisoning are less common than in sheep, recent cases, including 2 reported here, and anecdotal reports from other ranchers suggest that the impact of halogeton losses in cattle herds in the western United States is much more widespread than originally thought. Halogeton may accumulate up to 30% oxalates; a small amount of the plant (300 g) is enough to cause death in sheep. Oxalates precipitate calcium from the blood, resulting in hypocalcemia, formation of …

All Current Publications
Beef cattle require a number of dietary mineral elements for regular bodily maintenance, growth and reproduction. Minerals that are essential in larger amounts are labeled as major or macro elements. Those needed in smaller amounts are called micro, minor or trace minerals. These terms, have no relationship to the metabolic significance of a mineral in the diet. A trace mineral can be as crucial to the health and performance of an animal as a major mineral.

Utilizing Single Nucleotide Polymorphism Analysis In Determining Parentage Of Cattle, Nicole M. Elbert
Undergraduate Honors Capstone Projects
Parentage identification within cattle herds is an important aspect of record keeping. It is essential for accurate registration within a purebred association and decision making for production purposes, such as replacement heifer and sire selection. Methods used to identify parentage have evolved from utilizing blood protein antigens, restriction fragment length polymorphism (RFLP) and microsatellites to the current technology of analyzing DNA profiles for differing single nucleotide polymorphisms (SNPs). In this preliminary study we analyzed genotype data from 1,066 samples obtained from various cattle breeds. These breeds included Holstein, Angus, Hereford, Irish Black, Jersey, Red Angus, Limousine, Charolais, Brown Swiss and …
