Molasses-Fat Blend As An Energy Source And Conditioning Agent In Feedlot Diets (1998), A.S. Flake, Gerry L. Kuhl, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Seventy-two yearling crossbred steers were used in an individual feeding trial to evaluate the effects of adding a molasses-fat blend (Synergy® 19/14; Cargill Molasses Liquid Products) to diets at 6 or 12% (dry basis) on growth performance, carcass traits, and feed intake behavior. Dry-rolled corn was processed to a mean geometric particle size of either 2,000 or 3,800 microns. Adding the liquid supplement at 6% to the coarse-rolled finishing ration improved gain (P<.1) and feed efficiency (P<.1). Incorporation of Synergy 19/14 into feedlot rations may help reduce fluctuations in feed intake.

Interviews were conducted with cattle feeders, beef packers, and others involved in the beef industry to project how fed cattle prices will be discovered in the next decade. Respondents generally indicated that economics will determine beef's market share in 2010, how important public grades and grading will be, and whether consumer brands for fresh beef will become common. Economics also will determine how much influence alliances will have, whether most cattle will be marketed by some value-based pricing system, and what changes will occur in market information and futures markets.

Dry Aging: An Old Process Revisited (1998), R.E. Campbell, Melvin C. Hunt
Kansas Agricultural Experiment Station Research Reports
Dry aging of beef cuts, once considered the "gold standard" for premium palatability, is practiced by only a few processors. We were asked by a major southern meat purveyor to study variables of dry-aging processing. Detailed sensory analyses of flavor, juiciness, and tenderness clearly indicated that beef loins dry aged for 14 and 21 days were superior for all three traits to a product vacuum aged for 14 days and to a product dry aged for 7 days. In addition, dry- aged steaks could be vacuum packaged and stored for up to 16 days without losses in palatability. Dry aging …
Grid Pricing Of Fed Cattle (1998), Ted C. Schroeder
Grid Pricing Of Fed Cattle (1998), Ted C. Schroeder
Kansas Agricultural Experiment Station Research Reports
Pricing fed cattle on a value-based quality and yield grade grid provides the best opportunity for cattle producers to receive premiums associated with high quality cattle. However, grid discounts for cattle not desired by the particular packer are often quite substantial. Thus, cattle producers targeting cattle for specific grids need to have considerable knowledge regarding the quality attributes of their cattle. This study compared pricing of 202 pens of fed cattle on a live basis, a carcass (dressed) basis, and using four different packer grids. Results indicate that no single pricing method is optimal for all cattle. Producers need to …
Effects Of Feeding Rumensin® In A Mineral Mixture On Steers Grazing Native Grass Pastures (1998), F.K. Brazle, S.B. Laudert
Effects Of Feeding Rumensin® In A Mineral Mixture On Steers Grazing Native Grass Pastures (1998), F.K. Brazle, S.B. Laudert
Kansas Agricultural Experiment Station Research Reports
Four hundred sixty-nine English and Continental cross yearling steers grazed on native grass pastures over a 2-year period. Rumensin® was added (1,620 g/ton) to the mineral mixture in half of the pastures. Some of the pastures were used from April 23 to July 15 and the remainder from April 23 to August 15. The pooled data for the grazing periods indicated that Rumensin supplemented steers gained 7.7% faster(P<.05) and consumed 32% less mineral (P<.05) compared to the control steers.
Differences In Efficiency Among Kansas Beef Cow Producers (1998), S. Eidson, Michael R. Langemeier, R. Jones
Differences In Efficiency Among Kansas Beef Cow Producers (1998), S. Eidson, Michael R. Langemeier, R. Jones
Kansas Agricultural Experiment Station Research Reports
Beef cow producers must manage costs of production and improve production efficiency to compete with hog and poultry and other beef cattle producers. A sample of 46 beef cow enterprises from the Kansas Farm Management database was used to measure technical, economic, and overall efficiencies. On average the farms were 92% technically efficient, 80% economically efficient and 73% overall efficient. Our results suggest that 5% increases in economic and scale efficiencies would increase profit per cow by $20 and $24, respectively.

Thermal imaging of feedlot cattle ears is a noninvasive diagnostic tool that aids in identifying properly placed or abscessed growth-promoting implants. Thirty-two calves were used to determine if abscessed and normal, functional implants could be identified and differentiated using infrared thermography. Infrared images were taken at implantation on days 2, 4, 7, 14, and 21 after implantation. Abscessed implants were easily identified. Use of thermal imaging can verify implant administration and, thus, has the potential to immediately impact feedlot quality assurance programs.

Crossbred yearling heifers were allotted randomly to three grazing implant treatments: 1) control (CONT), 2) Component® E-H (CEH), and 3) Ralgro® (RAL). After grazing native grass for 74 days, the heifers were transported to a western Kansas feedlot. All heifers were implanted with Synovex-H® upon arrival at the feedlot and were reimplanted70 days later with Finaplix-H®. The CEH heifers gained faster while on grass (P<.10) and in the feedlot than the RAL heifers. The CEH heifers had heavier carcasses than RAL heifers. Control heifers had the largest ribeyes. Other carcass traits, including USDA quality grade, were not influenced by pasture treatment. In this study, administration of CEH to heifers grazing native grass optimized overall performance whencombined with the feedlot implants (Synovex-H and Finaplix-H).

Microbial Evaluation Of Steam Pasteurization And Comparison Of Excision Versus Sponge Sampling Recovery (1998), D.L. Retzlaff, S.A. Rueger, Randall K. Phebus, James L. Marsden, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
The use of steam pasteurization (SPS400™; Frigoscandia, Bellevue, WA) as a viable commercial-scale intervention method to treat pre-rigor beef carcasses uniformly hasbeen evaluated for temperatures from 180E to 201 ÌŠF. Effectiveness at lower temperatures(minimum atmospheric temperature of 170 ÌŠF) has not been evaluated. Previous studies of steam pasteurization used excision sampling. However, the USDA-FSIS has suggested use of nondestructive sampling of chilled beef carcasses for generic Escherichia coli, so we compared excision and sponge sampling in a commercial slaughter facility. Twenty-eight beef carcasses were monitored to determine the effectiveness of steam pasteurization and to compare the two sampling methods. Total …

Kansas Agricultural Experiment Station Research Reports
Twenty ruminally fistulated steers were used in different two experiments to evaluate the effects of supplemental carbohydrate source (starch, glucose, fructose, or sucrose) fed at .3% BW/day on the utilization of low-quality tallgrass-prairie hay. In Experiment 1, all supplemental carbohydrates were fed with a low level of supplemental degradable intake protein. In Experiment 2, the level of supplemental degradable intake protein was high. Intake of the tallgrass-prairie hay was not affected significantly by supplementation in either experiment, but as a result of the added carbohydrate, total intake was increased. When supplemental protein intake was inadequate, supplemental carbohydrates depressed digestion, but …

Our objective was to determine the effect of site of semen deposition on pregnancy rate in beef cows inseminated at a fixed time or after observed estrus. Cows were synchronized with a combination of gonadotropin-releasing hormone (GnRH) prostaglandin-F α (PGF). GnRH was injected 7 days before PGF (day 0; first of breeding season). The trial was conducted at two locations, one in Kansas (147 cows) and one in Colorado (313 cows). At each location, cows were assigned to be inseminated after observed estrus (ESTRUS-AI) or at a fixed time (TIMED-AI). Within these two groups, cows either were inseminated in the …
Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay (1998), C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports
A study with 16 ruminally fistulated beef steers fed Bermuda hay ad libitum showed that the intake and digestibility of hay was not influenced by increasing levels of supplemental degradable intake protein (DIP). However, the hay used in this study was of medium quality; lower quality Bermuda hay with lower CP may respond to supplemental DIP.

Kansas Agricultural Experiment Station Research Reports
Twenty ruminally fistulated beef steers free-choice access to prairie hay were used to evaluate the effect of increasing level of soybean meal (SBM) on forage intake and digestion. Forage intake, total organic matter intake, and organic matter digestion were enhanced with increasing level of SBM supplementation, although forage intake and digestion appeared to plateau at higher levels. The concomitant rises in intake and digestion as supplemental SBM increased resulted in an increase in total digestible organic matter intake, with the largest response to the initial increment of supplement.
Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation (1998), G.C. Lamb, K. E. Thompson, J.S. Heldt, C.A. Löest, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports
Three treatments were initiated at approximately 15 days after calving and continued for 4 weeks: 1) cows were suckled ad libitum by their calves (calf present [CP]); 2) calves were present but nonsuckling 24 hr/day and cows were milked twice daily (CR+2xM); 3) or same as CR+2xM but cows were milked five times daily (CR+5xM). Interval to the first postpartum ovulation was similar between CR+2xM and CR+5xM cows but about 2 weeks less than that in cows suckled ad libitum by their own calves. Cows in the CR+5xM treatment produced more milk than cows in the CR+2xM treatment, whereas only …

Effects Of Base Ingredient In Cooked Molasses Blocks On Intake And Digestion Of Prairie Hay By Beef Steers (1998), R.H. Greenwood, Evan C. Titgemeyer, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Blocks based on cooked beet molasses, cane molasses, or concentrated separator by-product, CSB) were tested to compare their effects on intake and digestion of prairie hay by beef steers. All blocks contained at least 30% crude protein. Steers fed the cooked molasses blocks consumed and 22% more forage than control steers, but forage intakes were not different among the three different blocks. Intakes of digestible organic matter and neutral detergent fiber, indicators of energy available to the steers, were increased 38 and 29% respectively, by block supple-mentation but were not different among the three blocks. However, total tract organic matter …
