The Influence of Chromium Supplementation on the Insulin Pathway, Carcass Traits, and Meat Quality of Feedlot Steers
… traits, meat quality, and the insulin pathway in feedlot steers. Calf-fed steers were allotted to 0 ppb (CON) or 400 ppb Cr propionate (Cr400) for 210d in experiment 1. Two longissimus muscle (LM) biopsies were collected to examine protein abundance and gene expression after adaptation to a …

The effects of molybdenum water concentration on feedlot performance, tissue mineral concentration, and carcass quality of feedlot steers
Thirty cross-bred steers (initial BW 375 ±37.2, replicate 1; and 535.0 ± 39.4 kg, replicate 2) were utilized to investigate the effects of Mo water concentration on performance, carcass characteristics, and mineral status of feedlot steers fed a growing and finishing diet for 151 and 112 d for …

Effects of Lubabegron supplementation on carcass traits, muscle fiber type, proteome profile and meat quality attributes of finished feedlot steers
… sixty (2,160) British and Continental crossbred steers were supplemented (1, 4, 3.2 or 5.0 g/ton (DM basis) Lubabegron and a control diet (Experior; EX, Elanco Animal Health) for the last 28, 56, or 84 d of the finishing period resulting in twelve treatment combinations. Fifteen pens (12 hd/pen) …

Effect of two finishing systems on claw characteristics in beef steers
… to the shape and balance of the foot in growing steers. The evaluated parameters included dorsal wall growth, abrasion, length and sole surface area. After animal harvest, the sole horn thickness was measured. Seventy-two yearling Angus-crossbred steers (mean body weight 378±6.2 kg) were allotted …

Effects of dry versus modified wet distillers grains with solubles with or without calcium oxide on economics, growth performance, and ruminal metabolism of beef feedlot steers
… with or without calcium oxide (CaO) treatment to feedlot steers on: (1) growth performance, economics of gain, and USDA carcass grades; (2) pattern of intake and meal distribution; and (3) diet digestibility and rumen parameters. Exp. 1: Steers (n = 139; average initial BW = 336 ± 75 kg) were used …

Residual feed intake, breed of sire and dam, and individual sire affect performance and carcass characteristics and rates of back fat and intramuscular fat of feedlot steers
… (S), Angus-Simmental, and Simmental-Angus steers across two years across were classified into high (H), medium (M), and low (L) residual feed intake (RFI) groups. Steers in the H RFI group ate 1 kg more of DMI (P< 0.05) per day than steers in the L and M RFI group. Steers in the L RFI group …

Effect of Zilpaterol hydrochloride and steroid implantation on yearling steer feedlot performance, carcass characteristics, and skeletal muscle gene expression
… and skeletal muscle gene expression in feedlot steers. Four treatments were used to analyze the effects of RS implanted 58 days before ZH, which was fed for 30 days with a 3 day withdrawal. It was determined that ZH and RS additively contribute to improved live and carcass performance; …

Predicting Beef Tenderness Using Ultrasound Technology
… study utilized 51 head of crossbred commercial feedlot steers. The cattle were selected on a criteria consisting of: Not more that 37.50% Bos Indicus influence, and not more than 18 months in age, with visual appraisal for fitness. A non-certified ultrasound technician, using an Aloka 500V …

Effects of rumen-protected lysine supplement on growth and carcass traits in a traditional finishing scheme with crossbred beef steers
The effects of rumen protected amino acids on feedlot performance and carcass characteristics are inconsistent in the literature. Therefore, the purpose of this experiment was to study the effects of rumen-protected lysine supplementation on feedlot performance and carcass characteristics on light …

Utilization of corn silage grown by conventional and sustainable methods fed with different nitrogen supplements
A metabolism trial and a feedlot finishing trial were conducted with silage made from corn (Zea mays L.) forage grown by conventional and sustainable methods. For the metabolism trial, 24 wether lambs were allotted to four diets: 1) conventional corn silage supplemented with urea, 2) conventional …

Agent-based and contact network modeling applications for Escherichia coli transmission in commercial feedlot settings
… though the transmission dynamics of STEC in feedlot cattle are not fully understood. Our current understanding of the transmission dynamics is dependent on longitudinal studies of naturally occurring STEC infections in cattle. A certified nonpathogenic strain of E. coli was used for a series …

COMPARING VARIOUS FIBER SOURCES THROUGH MEASURING RUMINATION IN FINISHING BEEF CATTLE
… and rumination characteristics of feedlot steers. The first study evaluated the effect of roughage source on rumination time and growth performance response in finishing beef steers. We hypothesized that roughage source would not affect rumination time and growth performance because …

Effects of feeding ractopamine hydrochloride in combination with zinc or chromium on growth performance, carcass characteristics, and meat quality of finishing steers
… feed additives that have been widely fed by the feedlot industry in the last decade. One product available on the market is ractopamine hydrochloride (RAC), a beta-agonist that acts as a nutrient repartitioning agent to shift nutrient deposition from fat to lean tissue. There are other additives …

Evaluation of feedlot feed efficiency relationships as well as genetic and phenotypic performance, carcass, and economic outcomes
… carcass, and feed efficiency characteristics. Steers were all early weaned (78 ± 24 d) and managed similarly prior to weaning and in the feedlot. Steers were all of known Simmental (SM), Angus (AN), and SM x AN genetics. Steers were pen-fed and individual DMIs were recorded using the GrowSafe® …

EFFECTS OF DIETARY COMPOSITION AND FEEDING MANAGEMENT REGIMEN ON FEEDLOT CATTLE PERFORMANCE
… prevalence, and metabolic health in finishing feedlot steers. In a randomized complete block design, crossbred beef steers (n = 720) were assigned to 48 pens that housed 15 steers per pen. Treatments were arranged in a 2 × 2 factorial with the factors being diet and feeding management. Diets …
