Previous studies conducted with finishing cattle on the use of WDGS as a replacement of corn as an energy source resulted in consistently improved feed efficiency (Firkins et al., 1985; Larson et al., 1993; Ham et al., 1994; Trenkle, 1997a, 1997b; Fanning et al., 1999). ...

The incidence of Sulfur-induced PEM is more prevalent in the U.S. where high concentrations of S compounds exist in stock water. Producers typically do not have access to cost- effective alternative water sources in these areas. In addition to high-sulfur water, sulfur-rich feedstuffs, such as byproducts of the ethanol industry, increase the probability of Sulfur-induced PEM. The purpose of this study was to confirm previously observed variation in individual response to increased concentrations of dietary S and determine if the mineral compound zeolite effectively binds excess hydrogen ions in the rumen, limiting hydrogen sulfide production, and therefore reducing the risk of Sulfur-induced PEM. Steers (n = 96) were assigned to one of four treatment groups for a 77 d period: control (CTRL; ≤ 400 ppm S); high-sulfur water (HS; ≥ 3000 ppm ...

The objective of this study was to determine the effects of water quality during the growing period on subsequent finishing performance. In yr 1, 78 steers (374 kg) were assigned to one of eight pens (2-4 pens/treatment) based on

Dried distillers grains with solubles (DDGS) contain approximately 10% to 15% fat; however, minimal research to date has investigated DDGS specifically as a supplemental fat source. The objective of this experiment was to investigate

Prior to initiation of the trial, 192 steers (initial BW = 826 ± 18 lb) were blocked by receiving date, weighed, and randomly allotted to 16 dirt floor pens (48.2 ft x 113.8 ft; 5% slope). Pens were then randomly assigned to one of four dietary treatments. The control diet (CON) contained 82% cracked corn, 10% alfalfa hay, 4% molasses, 3.2% supplement, and 0.8% urea. In the remaining three treatment diets, all of the urea and portions of the cracked corn were removed and replaced with DDGS at 15% (15% DDGS), 25% (25% DDGS), and 35% (35% DDGS) of the diet DM. The diets were formulated to be isocaloric and to provide similar levels of crude protein (CP) for CON and 15% DDGS (13.2 and 13.3% CP, respectively) and a stepwise increase in CP for 25% and 35% DDGS (15.4 and 17.6%, respectively). Analysis of weekly feed samples collected throughout the trial determined that the CP concentrations were 11.4, 12.2, 14.3, and 16.5% for CON, 15% DDGS, 25% DDGS, and 35% DDGS, respectively.

Sixty Angus and Angus × Hereford steers were stratified by weight and initial liver Cu concentration within a breed and randomly assigned to treatments. Treatments consisted of: 1) control (no supplemental Cu); 2) 20 mg Cu/kg DM from Cu sulfate (CuSO 4 ); 3) 40 mg Cu/kg DM from CuSO 4 ; 4) 20 mg Cu/kg DM from Cu citrate; 5) 20 mg Cu/kg DM from Cu proteinate; and 6) 20 mg Cu/kg DM from tribasic Cu chloride. A corn silage-soybean meal-based diet was fed for 56 d. Steers were then switched to a high-concentrate diet. Equal numbers (n = 5) of steers per treatment were slaughtered after receiving the finishing diets for
