Comparing The Performance Of Cattle Castrated Using Different Techniques Upon Arrival At The Feedlot, Tyler Blackwood, Tyler J. Spore, Michael D. Kleinhenz, William R. Hollenbeck, Dale A. Blasi, A. J. Tarpoff

Kansas Agricultural Experiment Station Research Reports

Objective:To determine the least detrimental castration technique in terms of growth performance when castrating cattle upon entry to the feedlot.

Study Description:Intact bulls were sourced from the Southeastern U.S. and received at the Kansas State University Beef Stocker Unit. After backgrounding, 700-lb bulls were castrated using various techniques, including banding, banding with splitting of the distal scrotum, use of the Henderson Tool, and use of a burdizzo clamp. A group of intact bulls served as a negative control group. Weights were obtained at regular intervals throughout the 56-day study to quantify and compare growth performance.

Results:The day …

Kansas State University Feedlot Boot Camp And Teaching Program: Growing Student Interest And Engagement In The Feedlot Industry, Danielle M. Stock, Pete Anderson, Karol E. Fike

Kansas Agricultural Experiment Station Research Reports

Objective:Our objectives were to summarize the development and structure of the Kansas State University Feedlot Boot Camp and Teaching Program and examine student interest in careers in the feedlot industry after participation.

Study Description:Since 2019, 95 Kansas State University College of Agriculture undergraduate students participated in the Feedlot Boot Camp Program. The aim was to develop students’ knowledge, skills, and professional relationships in feedlot management to help meet the critical need for trained professionals in the industry. Components are a four-day Feedlot Boot Camp, student presentations, animal health day, and an optional feedlot internship. Students who completed all …

Effect Of Feeding Interval On Finishing Performance Of Beef Steers, Chance Fiehler, John Jaeger, Justin Waggoner, Keith Harmoney, K.C. Olson

Kansas Agricultural Experiment Station Research Reports

It has long been accepted that optimal performance in beef cattle occurs when cattle are fed at a similar time each day. In fact, in Frederick Mumford’sSyllabus of Illustrated Lecture on Profitable Cattle Feedingpublished by the U.S. Department of Agriculture in 1905, Mr. Mumford stated, “Cattle should be fed at certain hours and in the same way. This cannot be varied 15 minutes without some detriment to the cattle.” Little research has been conducted examining interval of feed delivery. Most feedlot research examining feed delivery has focused on the comparison of once or twice daily feed delivery on …

Carcass Trait Trends For Steers And Heifers Finished Through The Tri-County Steer Carcass Futurity Cooperative From 2002 Through 2018, E. D. Mccabe, M. E. King, K. E. Fike, M. Groves, K. G. Odde

Kansas Agricultural Experiment Station Research Reports

Objective:The objective was to evaluate trends in carcass characteristics for steers and heifers finished through the Tri-County Steer Carcass Futurity Cooperative.

Study Description:Data analyzed included 74,207 steers and 33,529 heifers finished at the Tri-County Steer Carcass Futurity Cooperative (Lewis, IA) and harvested from 2002 through 2018. Steers and heifers were harvested at liveweights of 1,235.0 +/- 119.8 lb and 1,124.2 +/- 106.7 lb, respectively. Carcass trait trends evaluated for steers and heifers included calculated yield grade score, backfat thickness, hot carcass weight, kidney, pelvic, heart, fat percentage, marbling score, and ribeye area.

Results:Calculated yield grade scores increased …

Effects Of Dry And Liquid Pellet Binder Inclusion And Conditioning Temperature On Pellet Mill Efficiency And Pellet Quality Of A High-Fiber Ruminant Ration, Caitlin E. Evans, Marut Saensukjaroenphon, Charles R. Stark, Chad B. Paulk

Kansas Agricultural Experiment Station Research Reports

The objectives of this experiment were: 1) to determine the effects of sucrose and lactose-based liquid ingredient inclusion on the pelleting efficiency and quality of a high-fiber diet; and 2) to evaluate the role of mash conditioning temperature on the binding effectiveness of the tested liquid ingredients. Binders included DLS (dry calcium lignosulfonate), LCM (liquid cane molasses), LMB (commercial liquid molasses blend), and LLB (commercial liquid lactose blend). Treatments were arranged in a 5 × 3 factorial of pellet binder (control, DLS, LCM, LMB, and LLB) and conditioning temperature (165, 175, and 185°F). Data were analyzed using the GLIMMIX procedure …
