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 …

Animal, Dairy, and Veterinary Science Faculty Publications

The primary objective was assessment of effect of sample pooling on Tritrichomonas foetus detection using qPCR in beef bulls within 5 logs of trichomonad concentration in spiked preputial samples. The secondary objective was to use qPCR Ct values to estimate the percentage of beef bulls in the field population within each log of trichomonad concentration. Solutions containing none, 1,10,100,1000 and 10,000 trichomonads (T)/ml were made and tested by qPCR. Test sensitivities for single positive samples were: 1 T/ml, 20/40 (50%); 10 T/ml, 40/40 (100%); 100 T/ml, 40/40 (100%); 1000 T/ml, 40/40 (100%); 10,000 T/ml, 40/40 (100%). For 5-sample pools (1 …

Using A Rising Plate Meter To Determine Paddock Size For Rotational Grazing, Jennifer W. Macadam, Sara R. Hunt Oct 2015

Using A Rising Plate Meter To Determine Paddock Size For Rotational Grazing, Jennifer W. Macadam, Sara R. Hunt

All Current Publications

For rotational grazing of pastures to be most successful, it’s important to match pasture production to ruminant intake, because both can change during the grazing season. This publication shows how a rising plate meter can be used to calculate available pasture dry matter, allowing pasture managers to optimize pasture utilization and ruminant production on pasture.

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.


Grain Finishing Beef: Alternative Rations, Cattle Performance And Feeding Costs For Small Feeders, Dillon M. Feuz, Jesse Russell Jan 2014

Grain Finishing Beef: Alternative Rations, Cattle Performance And Feeding Costs For Small Feeders, Dillon M. Feuz, Jesse Russell

All Current Publications

In a feeding trial at Utah State University during the summer of 2013, it was found that cattle had higher ADG when fed SFC compared to whole corn. However, when the relative cost of SFC and whole corn were considered, feeding whole corn compared to SFC resulted in nearly identical feed costs per pound of gain. Actual and relative costs of SFC and whole corn can and do vary over time and across geographic regions. Therefore, feeders could use the information in this fact sheet to determine which feed will be the most economical for them.

Identification And Quantification Of Flavor Attributes Present In Chicken, Lamb, Pork, Beef, And Turkey, Curtis Maughan, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

The objectives of this study were to use a meat flavor lexicon to identify and quantify flavor differences among different types of meats such as beef, chicken, lamb, pork, and turkey, and to identify and quantify specific flavor attributes associated with “beef flavor” notes. A trained descriptive panel with 11 participants used a previously developed meat lexicon composed of 18 terms to evaluate the flavor of beef, chicken, pork, turkey, and lamb samples. Results show that beef and lamb samples can be described by flavor attributes such as barny, bitter, gamey, grassy, livery, metallic, and roast beef. Inversely related to …
