Nutrition, Dietetics, and Food Sciences Faculty Publications

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 …


Understanding The Decline In Successful Cattle Pregnancies, Andre Tu Nguyen Feb 2022

Understanding The Decline In Successful Cattle Pregnancies, Andre Tu Nguyen

Research on Capitol Hill

USU junior Andre, a local Loganer, studies computer science and biology.He has been working in an animal science lab. Over time, we have seen a decline in successful dairy cattle pregnancies. This is a huge cause for concern for Utah, with milk sales at an estimated value of $405 million in 2020. Andre’s work has been in studying a certain protein in pregnant cattle; now that he has determined there is a decrease in this protein over the course of the pregnancy, he hopes to see whether that might impact its viability. Andre got involved in research in a high …

Medication Darts Are Gaining In Popularity - Do They Affect Meat Quality? Are There Risks?, David J. Wilson, Kerry A. Rood Feb 2019

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 …


Calf And Yearling Prices In California And The Western United States, Tina Saitone, Larry C. Forero, Glenn A. Nader, Leslie A. Forero Oct 2016

Calf And Yearling Prices In California And The Western United States, Tina Saitone, Larry C. Forero, Glenn A. Nader, Leslie A. Forero

Wildland Resources Student Research

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, …

Thomas, Amanda Wilhelm, Benjamin R. Sessions, Brady A. Hicks, Donald H. Schlafer, Kenneth L. White, Christopher J. Davies Aug 2016

Trophoblast Major Histocompatibility Complex Class I Expression Is Associated With Immune-Mediated Rejection Of Bovine Fetuses Produced By Cloning, Heloisa M. Rutigliano, Aaron J. Thomas, Amanda Wilhelm, Benjamin R. Sessions, Brady A. Hicks, Donald H. Schlafer, Kenneth L. White, Christopher J. Davies

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 …

Research has shown that as a cow’s mature weight increases, feed efficiency decreases, as well as reproductive efficiency and other production factors. The purpose of this fact sheet is to illustrate the differences economically between three different cow weights (1,000 lbs., 1,200 lbs. and 1,400 lbs.) on three different resource bases.


Halogeton (H. Glomeratus) Poisoning In Cattle: Case Report, Kerry A. Rood, Kip E. Panter, Dale R. Gardner, Bryan L. Stegelmeier, Jeffery O. Hall Apr 2014

Halogeton (H. Glomeratus) Poisoning In Cattle: Case Report, Kerry A. Rood, Kip E. Panter, Dale R. Gardner, Bryan L. Stegelmeier, Jeffery O. Hall

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 …


Beef Cattle Nutrition, Minerals, Troy D. Cooper, Darrell Rothlisberger, Dale Zobell Feb 2014

Beef Cattle Nutrition, Minerals, Troy D. Cooper, Darrell Rothlisberger, Dale Zobell

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.

All Current Publications

Raising beef cattle can be very rewarding. First, if you like raising cattle, maintaining your tie to the land, and seeing the product of your labors, it can truly be satisfying to see young calves in the spring, watch them grow and progress. Second, here can also be a financial reward when the calves are weaned and sold. However, the satisfaction of these two aspects may all depend on your herd’s efficiency and profitability.
