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 …

Phosphorus excretion in beef steers as impacted by increasing levels of corn gluten feed
… of P on fecal P excretions. Eight Hereford steers (427±79 kg) were randomly assigned to one of four dietary treatments in a 4 x 4 replicated Latin square design. Steers were fed chopped grass hay ad libitum (0.13% P) and 0, 0.5, 1.0 or 1.5 kg/d of dried CGF pellets. All steers were …

Effects of weaning age and maternal nutrition on gene expression of longissimus muscle of beef steers
… were studied. The longissimus muscle (LM) of beef steers on an early weaning (141 days age) plus high-starch diet (EWS) or a normal weaning (NW, 222 days age) plus starch creep-feed diet (CFS) was biopsied at 0 (EW), 25, 50, 96 (NW), 167, and 222 (pre-slaughter) days. Expression patterns of 35 …

Effects of early weaning on finishing feed efficiency, marbling development and retail product quality of beef steers
Beef cattle producers continuously search for nutritional management options that provide flexibility to production scenarios. Due to its positive effects on maternal productivity, early weaning is one such alternative strategy that has received considerable interest. To better understand the …

FEEDLOT PERFORMANCE AND IMMUNOLOGY OF BEEF STEERS FED A LOW VITAMIN A DIET AND SELECTED FOR ADH1C GENOTYPE
… fat (IMF) in the longissimus thoracis muscle in beef cattle. The intent of this study was to determine whether this marker-assisted management (MAM) strategy would be effective at a commercial level, and whether there would be any immune function ramifications from limiting dietary VA. This …

Spatial Allocation of Forages and Its Impact on Grazing Behavior, Diet Selection and Dry Matter Intake of Beef Steers
… as adjacent monocultures were grazed by beef steers in the present set of experiments. Steers exhibited a partial preference for alfalfa of 61 to 65% when given a choice of grazing alfalfa or tall fescue as adjacent monocultures, regardless of the ground area proportion of the two forages …

Estimating forage mass of tall fescue pastures and dry matter intake and digestibility of fescue forage by beef steers
… and dry matter intake and digestibility in beef steers under indoor and grazing conditions. Forage mass was estimated with the herbage cutting method (HCM) and three indirect methods; the pasture capacitance meter (PCM), the plate meter (PPM), and the visual estimation (VE). The coefficients …

Grazing Behavior of Beef Steers Grazing Endophyte-Infected, Endophyte-Free, and Novel Endophyte Infected Tall Fescue, and Lakota Prairie Grass
… endophyte (Q) tall fescues. Angus-crossbred steers (279±8 kg) steers wore electronic behavior data recorders in four sampling periods, and direct visual appraisals of behavior were taken in five sampling periods during the months of May to September, 2004. Overall, during the visual appraisal …

Effects of rumen-protected lysine supplement on growth and carcass traits in a traditional finishing scheme with crossbred beef steers
… and carcass characteristics on light weight steers. This 198-d experiment used 192 crossbred steers (BW 266 kg ± 11.2) in a completely randomized block design, which blocked steers by initial body weight (BW) and by arrival source (Bos indicus crossbreds were blocked separately from the Bos …

The growth pattern of various body and carcass parts and proportions of beef steers as influenced by different planes of nutrition
… various body and. carcass measurements of beef steers were considered for statistical analysis. The slaughter data were obtained from an experiment conducted at Blacksburg, Virginia, by members of the Animal Science Department of the Virginia Polytechnic Institute, described by Kelly et al. …

The palatability and nutrient value of tall fescue (Festuca arundinacea Schreb.) forage and evaluation of seven systems of forage finishing beef steers
Most cattlemen in the Southeast are in the cow-calf business and sell calves at weaning. The extra cost of shipping feeder calves for finishing and then shipping the carcasses back to the East adds to the price of meat. This practice also takes away a potential source of profit by farmers who could …

The Effect of Three Fescue Types and Lakota Prairie Grass on Copper Status, Dry Matter Intake, and Alkaloid Appearance of Beef Steers
… are responsible for large economic losses in the beef cattle industry each year. This research examined the effect of three fescue types [endophyte-infected Kentucky 31 tall fescue (E+), endophyte-free Kentucky 31 tall fescue (E-), non-ergot alkaloid-producing endophyte Q4508-AR542 tall fescue …

Effects of ractopamine hydrochloride on nutrient digestibility, environmental N excretion, regulation of skeletal muscle growth, and beta-receptor subtypes in finishing beef steers
… complete block design, twelve Simmental × Angus steers were assigned dietary treatments including a control (without Actogain; CON) or 400 mg·steer-1·d-1 ractopamine hydrochloride (RAC) for 35 d before slaughter. Two 5 d sampling periods were conducted on each block for total collection of feed, …

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 dietary …

Effects of endocrine modifiers on growth, carcass characteristics, and blood and tissue metabolites of finishing beef cattle
… and lipogenic enzyme activity were evaluated in beef cattle. In 1 experiment steers were fed 1 of 5 supplemental levels of vitamin A (0, 1,103, 2,205, 4,410, or 8,820 IU/kg DM). Final BW, G:F, ADG, HCW, LM area, marbling, and quality grade distribution did not differ among treatments. Except for …

Effect of Time of Supplementation on Performance and Grazing Behavior of Grazing Steers
Beef cattle follow a daily, cyclical pattern of grazing, rumination, and digestion that coincides with their environment and season. Traditionally backgrounding operations hand feed any supplement in the morning. However, this practice may interrupt typical grazing patterns during early morning and …

Application of yeast technology in ruminant nutrition
… commercially available to feed in the diets of beef cattle; these two applications are dried distiller's grains with solubles (DDGS) and yeast culture (YC). First, DDGS were offered as a protein and energy supplement to pregnant range cows to evaluate performance, and nitrogen and trace mineral …
