Effect Of Lighter (273 Kg) And Heavier (356 Kg) Initial Weight On Growth Performance Of Single-Source, Pre-Conditioned Beef Steers Fed A Single Growing-Finishing Diet, Thomas C. Norman
Electronic Theses and Dissertations
The objective of the study was to determine the influence that initial BW has on growth performance responses, efficiency of dietary net energy (NE) utilization, and carcass traits in feedlot steers. Light- and heavy-weight Charolais×Red Angus steers (n = 70) selected from a larger single-source group were used in a 209-d growing-finishing feedlot experiment at the Ruminant Nutrition Center, in Brookings, SD. On d-0 and d-1 weight and hip height (HH) measurements were collected for allotment purposes; the initial experimental weight was the average between d 0 and d 1 BW. Steers were assigned to two groups based on initial …
Optimization Of Forage Use In Diets Fed To Backgrounding And Finishing Cattle In The Northern Great Plains, Thomas G. Hamilton
Optimization Of Forage Use In Diets Fed To Backgrounding And Finishing Cattle In The Northern Great Plains, Thomas G. Hamilton
Electronic Theses and Dissertations
The two studies in this thesis were conducted to: 1) investigate the impact of corn silage moisture content and kernel processing at harvest on growth performance, efficiency of dietary net energy utilization, and carcass traits in finishing steers when fed at 20% DM inclusion in diets containing modified distillers grains plus solubles; and 2) determine the influence of equal cumulative roughage inclusion in a single diet or twodiet system during a 210-d backgrounding-finishing period in pre-conditioned beef steers on growth performance responses, efficiency of dietary net energy (NE) utilization, and carcass traits. Experiment 1 was a 112-d finishing experiment conducted …
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 …
Effect Of Inclusion Rate Of Silage With Or Without The Presence Of Alpha-Amylase On Feedlot Performance, Carcass Characteristics, And Efficiency Measures, W. C. Rusche, J. A. Walker, Z. K. Smith
Effect Of Inclusion Rate Of Silage With Or Without The Presence Of Alpha-Amylase On Feedlot Performance, Carcass Characteristics, And Efficiency Measures, W. C. Rusche, J. A. Walker, Z. K. Smith
SDSU Beef Day 2020 Summary Publication
The experimental objective was to determine the interactions of silage variety and inclusion level in cattle finishing diets on cattle performance and agronomic returns to cropland when fed to beef cattle.
