A Comparative Life Cycle Assessment Of Nutritionally Equivalent Meals With And Without Pork, Kelli Young
A Comparative Life Cycle Assessment Of Nutritionally Equivalent Meals With And Without Pork, Kelli Young
Graduate Theses and Dissertations
The following report details a life cycle assessment of several dietary and meal scenarios with and without pork. The goal of the LCA was to identify the impacts of greenhouse gas emissions, water use, and land use of pork containing and porkless diets and meal plans in a field-to-fork analysis. The dietary and meal plan scenarios are iso-caloric meaning they contain the same number of calories. The first set of diets is based on a USDA consumption pattern, 2000 kcal per day. This diet was used to create three other dietary scenarios with and without pork. The USDA recommended food …
Supplemental Trace Minerals (Zn, Cu, And Mn) As Sulfates Or Hydroxy Trace Mineral Sources For Beef Heifers, Randy Hunter Burnett
Supplemental Trace Minerals (Zn, Cu, And Mn) As Sulfates Or Hydroxy Trace Mineral Sources For Beef Heifers, Randy Hunter Burnett
Graduate Theses and Dissertations
Crossbred heifers (n = 286, 255 ± 4.5 kg initial BW, 295 ± 16.5 d of age) were used over a 2-yr period to determine the effects of mineral source on beef heifer development at 2 locations (n = 71 and n = 72, Fayetteville, blocks 1 and 4; n = 72 in each of 2 breeding groups, Batesville, blocks 2 and 3). Heifers were stratified based on initial BW, age, health, prior research projects, and sire, and then assigned to 6 groups of 12 heifers, that were assigned randomly to 1 of 2 trace mineral treatments. The 2 treatments …
Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content, And Palatability In Simulated Retail Display, Fred W. Pohlman Ii
Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content, And Palatability In Simulated Retail Display, Fred W. Pohlman Ii
Animal Science Undergraduate Honors Theses
Nutritional concerns and attempts to limit fat in the diet over the past decades have impacted the protein market, decreasing red meat consumption as well as prompting the advent of lean and extra lean ground beef. Such lean blends of ground beef may suffer in palatability, however, resulting in less satisfied consumers turning to other protein sources. While consumers are demanding lean ground beef, fatter blends may be more palatable. This study seeks to bridge the gap between perceived health and palatability by evaluating preferred fat content and instrumental color characteristics between labeled and unlabeled packages of ground beef in …
Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English
Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English
Food Systems
With increasing public concern and awareness of agricultural sustainability issues, comprehensive methodologies such as life cycle assessment are required to benchmark the beef industry and identify areas of opportunity for continuous improvement. To that end, the Beef Checkoff completed a retrospective sustainability assessment benchmark in 2013 by using Eco-efficiency analysis to compare the years 2005 and 2011. At the time of the analysis, the methodology used was the most up-to-date and comprehensive – indeed the analysis remains one of the only complete cradle-to-grave assessments of the U.S. beef industry. In 2015, a further refined version of the Eco-efficiency analysis was …

Genetic sequencing in beef cattle (Bos taurus L.) is expected to aid producers with selecting breeding stock. Using data from experimental trials conducted with Angus, Brahman, and their reciprocal cross, the single nucleotide polymorphism (SNP) P450 C994G marker expression was investigated for use in selecting genetics suited to grazing endophyte-infected tall fescue (Festuca arundinacea Schreb. L.) compared to bermudagrass (Cynodon dactylon L.) pasture. The study is unique in the sense that actual cow-calf breeding failure rates (open cows were not culled) were tracked from 1991 to 1997 on herds that were bred to calf in spring and were either exposed …
Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.
Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.

Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

Nutritional concerns have impacted the protein market, decreasing red meat consumption as well as prompting the advent of lean and extra lean ground beef. However, such lean blends of ground beef may suffer in palatability. This study seeks to bridge the gap between perceived health and palatability. Participants were asked to identify the relative importance of characteristics commonly used in purchasing ground beef and select a preferred package of ground beef from labeled and unlabeled sections consisting of 4%, 10%, 20%, and 27% fat content. Instrumental color data and their main drivers were also collected. Participants then completed a blind …
