1. Foster, Tristan Parker. A comparison of beef traceability models during serial and parallel processing methods.

Degree: 2016, Michigan State University

Thesis M.S. Michigan State University. Animal Science 2016

ABSTRACTA COMPARISON OF BEEF TRACEABILITY MODELS DURING SERIAL AND PARALLEL PROCESSINGByTristan Parker FosterTraceability of beef attributes through supply chains is a market barrier. Automatic identification and data capture technologies offer the feasibility of maintaining animal and product data through carcass fabrication. Individual animal identity of fifty-four (54) beef carcasses were maintained through the supply chain. Carcasses were fabricated into wholesale cuts using a serial processing method (SPM) or a parallel processing method (PPM). The goal of this study was to identify labeling techniques for two different processing methods, SPM and PPM, in tracking wholesale meat cuts back to the original animal in mid-sized processing facilities. The objectives of the study were 1) to determine the cost of additional labor required for traceability; 2) determine both consumable and fixed costs of traceability; 3) test traceability accuracy utilizing DNA matching.The mean number of in-process labels generated per carcass for SPM was 3.7 and for PPM was 30.9 (P < 0.01). The amount of time required for generating in-process labels for SPM (2 min 16 sec) was less than PPM (8 min 45 sec) (P = 0.01). The amount of time required to label each carcass was less (P < 0.01) for SPM (18 sec) than for PPM (3 min 10 sec) which required in-process labels. Total cost of traceability, including fixed and consumable cost per carcass, was nearly twice as much for PPM (17.98) than SPM (9.02). Traceability, for both processing methods, was found to have 100% fidelity, as verified using DNA marker genotyping.

2. Kroll, Lee Anne K. Effects of tail docking on behavior, performance and health of beef cattle raised in confined feedlots.

Degree: 2013, Michigan State University

Thesis M.S. Michigan State University. Large Animal Clinical Sciences - Master of Science 2013.

ABSTRACTEFFECTS OF TAIL DOCKING ON BEHAVIOR, PERFORMANCE AND HEALTH OF BEEF CATTLE RAISED IN CONFINED FEEDLOTSByLee Anne K. KrollTail docking of feedlot cattle is a management practice used in some confined, slatted floor feedlots of the Midwestern United States. Justification for tail docking is to reduce tail injuries and their sequelae, and improve performance. Limited evidence exists to support these claims and the practice of routine tail docking is an animal welfare concern in regards to pain and loss of the tail for communication and fly avoidance. The primary objective of the research conducted for this thesis was to determine the effect of routine tail docking on performance and health parameters of feedlot cattle housed in a confined slatted floor feedlot facility and behavioral response following tail docking. Cattle were randomly assigned to 1 of 2 treatment groups; docked (DK) or control (CN). All calves received the same pre- and post-operative analgesia and DK calves had the distal two-thirds of their tail removed with pruning shears. For all performance trials, we found no significant effect of treatment on performance, carcass, morbidity, mortality or lameness. Tail injuries were present among 60-76% of cattle that were not tail docked. Behavior studies demonstrated increased fly avoidance activity and signs of acute pain in DK calves. We were unable to identify a performance or health advantage to tail docking, and we observed signs of compromised welfare in feedlot cattle following tail docking. However, tail tip injuries persisted in cattle raised in slatted floor facilities. Because routine tail docking of cattle housed in confined, slatted floor facilities does not appear to improve performance and cattle welfare is compromised, alternative solutions to reduce the incidence of tail tip injury should be considered.

3. Bronkema, Sara M. A nutritional survey of commercially available grass-finished beef.

Degree: 2018, Michigan State University

Thesis M.S. Michigan State University. Animal Science 2018

Consumer interest in the source of their food, its environmental footprint, and the impact of diet on health has supported the growth of the grass-finished beef (GFB) industry. Studies have concluded that GFB has distinct nutritional differences from conventionally-finished beef. As the GFB industry continues to expand, it is vital to continue to explore the nutritional complexities and variation in the product. To achieve this aim, a survey of grass-finishing production systems throughout the U.S. was conducted, and the beef finished on participating farms was analyzed for its nutritional composition, including fatty acid (FA), mineral and fat-soluble vitamin content. Annual production capacity of farms ranged from 25 to 5,000 cattle, with a mean age of cattle at harvest of 26.8 ± 2.3 months. An array of finishing diets included grazing exclusively perennial pasture, the incorporation of annual forage crops, as well feeding a variety of harvested forages and supplementation of non-starch feed byproducts. The ratio of omega-6 (n-6) to omega-3 (n-3) FA in beef samples averaged by producer ranged from 1.8 to 28.3, with an overall sample set median of 4.1. Only n-3 FA varied between harvest season, with a greater amount found in beef harvested in the spring. Mineral content was highly variable by season and producer, due to the inherent variation of soil and forage mineral content. Mean α-tocopherol content was 610.6 μg/100 g beef, and mean β-carotene content was 32.2 μg/100 g. The amount of these antioxidants also varied between producers, but tended to be greater in beef finished solely on fresh forages. This survey indicates that commercially available GFB can vary in its nutritional composition due to the diverse practices used to grass-finish cattle.
