The Influence Of Carcass Weight On Beef Primal Temperature, Tenderness, And Palatability, Samantha Egolf
The Influence Of Carcass Weight On Beef Primal Temperature, Tenderness, And Palatability, Samantha Egolf
Electronic Theses and Dissertations
The United States beef industry has experienced increasing hot carcass weights (HCW) and improvements to quality grade the last three decades. Postmortem chilling of beef carcasses is critical to overall product quality. Carcass weight and composition may influence carcass temperatures during postmortem chilling. The objective of this research was to evaluate the effects of HCW and quality grade during postmortem chilling and on product quality. A-maturity carcasses were selected by weight [light = 296–341 kg; middle = 386–432 kg; heavy = 466–523 kg]. A 20 cm data logger was placed into the chuck and round and a 10 cm data …
Management And Dietary Strategies To Mitigate Environmental Stressors In Northern Plains Cattle Feeding Systems, Warren Carl Rusche
Management And Dietary Strategies To Mitigate Environmental Stressors In Northern Plains Cattle Feeding Systems, Warren Carl Rusche
Electronic Theses and Dissertations
Three studies were undertaken to examine strategies to mitigate environmental stress faced by Northern Plains cattle feeders. In the first study, 46 feedlot managers from SD (n = 21), MN (n = 6), and NE (n = 19) were surveyed on use and perceptions of heat stress (HS) mitigation strategies. All respondents avoided cattle handling during heat stress events and incorporated some method of HS mitigation. Buildings or shades were perceived as the most successful strategy (60.9%) and were most commonly named as strategies managers would like to employ (63% for shades and 17.4% for buildings). Increasing dietary corn silage …
Impact Of Carcass Chilling System On Carcass Characteristics And Biochemical Changes In Beef Carcasses, Lydia Margaret Hite
Impact Of Carcass Chilling System On Carcass Characteristics And Biochemical Changes In Beef Carcasses, Lydia Margaret Hite
Electronic Theses and Dissertations
Effective and efficient chilling of beef carcasses will directly influence meat quality and consumer acceptance. Over the past century the United States’ meat industry has evolved, and spray chilling system have become common practice utilized by the beef industry. However, many of the chilling systems presently in use were designed to chill carcasses averaging lighter than the average beef hot carcass weight of today. Beef hot carcass weight has increased 68 kilograms from 1991 to 2019. The increase in beef hot carcass weight could result in longer chilling periods and present possible challenges for chilling systems used by the beef …
