Dietary Fat And Calcium Level Effect On Feedlot Performance And Carcass Merit In Steers, B. Bock, Robert T. Brandt Jr., D.L. Harmon Jan 1989

Dietary Fat And Calcium Level Effect On Feedlot Performance And Carcass Merit In Steers, B. Bock, Robert T. Brandt Jr., D.L. Harmon

Kansas Agricultural Experiment Station Research Reports

Feeding fat increased feed intake and average daily gain, but feed efficiency was not affected. Feeding high levels of calcium (.9%) had no overall effect, but may tend to increase intake when fed with diets that contain primarily vegetable fat or highly unsaturated fat products.


Soybean Meal+Milo, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Sources For Steers Fed Dormant, Native Tallgrass Forage In Drylot, T. Delcurto, R.C. Cochran, A.A. Beharka, E.S. Vanzant, Tiruvoor G. Nagaraja Jan 1989

Soybean Meal+Milo, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Sources For Steers Fed Dormant, Native Tallgrass Forage In Drylot, T. Delcurto, R.C. Cochran, A.A. Beharka, E.S. Vanzant, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Sixteen ruminally-cannulated steers consuming dormant tallgrass-prairie forage were randomly assigned to one of four treatments: 1) control, no supplement; 2) soybean meal (SBM)+sorghum grain; 3) alfalfa hay; or 4) dehydrated alfalfa pellets. Forage dry matter (DM) intake was at least doubled by all three supplemental protein treatments (P<.01). In addition, steers supplemented with dehydrated alfalfa pellets displayed 15% higher forage DM intakes than steers supplemented with SBM+sorghum grain or alfalfa hay. Total DM digestibility did not differ (P>.10) among treatments; however, fiber (NDF) digestibility was depressed in steers supplemented with SBM+sorghum grain or dehydrated alfalfa pellets, compared with controls. Results from this study reinforce the concept that supplemental protein improves forage intake and utilization. Additionally, alfalfa hay and dehydrated alfalfa pellets appear to be at least as ...


Polled Hereford And Simmental Milk Production, R.R. Schalles, S. Kimbrough, K.O. Zoellner, D.D. Simms Jan 1989

Polled Hereford And Simmental Milk Production, R.R. Schalles, S. Kimbrough, K.O. Zoellner, D.D. Simms

Kansas Agricultural Experiment Station Research Reports

The weigh-suckle-weigh method was used to measure milk consumption by 265 calves from 159 Polled Hereford and Simmental cows over 3 years. Calves nursing Polled Hereford cows consumed an average of 11.2 lbs of milk per day, with a peak of 15lbs at 50 days post"¢ calving. calves nursing Simmental cows consumed an average of 16.8 lbs of milk per day, with a peak of 20 lbs at 58 days after calving. All increase of 1lb in daily milk consumption produced approximately 20 lbs increase in weaning weight.


Feed Utilization During Late Gestation By Polled Hereford And Simmental Cows, R.R. Schalles, G.H. Kiracofe, J.W. Wright Jan 1989

Feed Utilization During Late Gestation By Polled Hereford And Simmental Cows, R.R. Schalles, G.H. Kiracofe, J.W. Wright

Kansas Agricultural Experiment Station Research Reports

Thirty-one Polled Hereford and 29 Simmental cows were individually fed two energy levels for about the last 4 months before calving. Weight, condition score, backfat thickness, and reproduction were evaluated. No differences were found in efficiency of feed utilization between breeds or between energy levels. These cows started the experiment in moderate body condition, and a 10% reduction in dietary energy level during late gestation did not affect their reproductive performance.


Influence Of Milk. Levels Of Beef Cows On Returns:A Simulation Approach, R.R. Schalles, K.O. Zoellner, L.S. Clarke Jan 1989

Influence Of Milk. Levels Of Beef Cows On Returns:A Simulation Approach, R.R. Schalles, K.O. Zoellner, L.S. Clarke

Kansas Agricultural Experiment Station Research Reports

Results of four simulated production systems indicated that high levels of milk produced calves that were heavier at weaning, primarily because of an increase in body fat. High levels of milk production, however, were a disadvantage when calves went directly to the feedlot. With slow-growing calves, the fat either had to be depleted postweaning, or the calves had to be slaughtered at less-than-desirable weights in order to maintain desirable carcass fat. High milk intake is more tolerable for calves with fast growth rates, whereas low milk intake is a an economic necessity for calves with slow growth rates. The moderate ...


Splay-Foot In Cattle, R.R. Schalles, R.W. Markham, H.W. Leipold, M.F. Spire Jan 1989

Splay-Foot In Cattle, R.R. Schalles, R.W. Markham, H.W. Leipold, M.F. Spire

Kansas Agricultural Experiment Station Research Reports

Angular limb deformity, observed in several breeds of cattle, results in a knock-kneed and splay-footed condition in the front legs. This study shows that angular limb deformity is a congenital structural defect, inherited as a simple, autosomal, recessive trait.


Syncro-Mate B® Induces Estrus In Cows Without Ovaries, W.J. Mcguire, G.H. Kiracofe Jan 1989

Syncro-Mate B® Induces Estrus In Cows Without Ovaries, W.J. Mcguire, G.H. Kiracofe

Kansas Agricultural Experiment Station Research Reports

Syncro-Mate B® was capable of inducing estrous behavior in ovariectomized cows. Lengthening the norgestomet implant period from 9 to 18 days did not prevent estrus. The ability of Syncro-Mate B to induce estrous behavior in ovariectomized cows helps explain the variable conception rates obtained after using this product in intact cows.


Relationship Of Milk Expected Progeny Differences (Epd's)To Milk Production And Calf Weaning Weight, T.T. Marston, D.D. Simms, R.R. Schalles, K.O. Zoellner, L.S. Clarke, G.M. Fink Jan 1989

Relationship Of Milk Expected Progeny Differences (Epd's)To Milk Production And Calf Weaning Weight, T.T. Marston, D.D. Simms, R.R. Schalles, K.O. Zoellner, L.S. Clarke, G.M. Fink

Kansas Agricultural Experiment Station Research Reports

Spring-calving Angus (n=37) and Simmental (n=28) cows were used to evaluate the relationship between milk expected progeny difference (EPD), milk production, total milk energy, and weaning weight. There were positive correlations between milk EPD's and milk produced during lactation, total milk energy per lactation, and calf weaning weight. On average, a 1 lb increase in milk EPD predicted a 1.8 lb increase in calf weaning weight and an increase of 56.6 (Angus) and 70.2 (Simmental) lb in total milk per lactation. Our results suggest that producers can use milk EPD's as selection tools ...


Conception Rates Of Beef Heifers Treated With Gnrh Analog At The Time Of Estrus Or At The Time Of Artificial Insemination., L.R. Corah, W.E. Beal, M.F. Spire, Jeffrey S. Stevenson Jan 1989

Conception Rates Of Beef Heifers Treated With Gnrh Analog At The Time Of Estrus Or At The Time Of Artificial Insemination., L.R. Corah, W.E. Beal, M.F. Spire, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Injecting a GnRH-analog at the time of estrus or at insemination did not generally improve conception rates in heifers inseminated following a synchronized estrus. However, within some herds. a significant positive response was noted.


Influence Of Limited-Creep Feeding On Pre- And Postweaning Performance Of Spring-Born Calves, C.E. Binns, F.K. Brazle, Gerry L. Kuhl, D.D. Simms, K.O. Zoellner, L.R. Corah Jan 1989

Influence Of Limited-Creep Feeding On Pre- And Postweaning Performance Of Spring-Born Calves, C.E. Binns, F.K. Brazle, Gerry L. Kuhl, D.D. Simms, K.O. Zoellner, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Limit-feeding a high protein creep (36% CP) and a high energy creep (16% CP) was compared with no supplementation in a 61-day preweaning trial. Salt was used to limit daily creep intake to 1.5 to 2.0 lb per head. Calves given the limited energy and protein creep feeds outgained (P<.01) the unsupplemented calves by 0.2 lb and 0.3 lb, respectively. Conversion of creep feed consumed to extra gain was 6.7 and 5.3 for the energy and protein creep-fed calves, respectively (salt included). Trucking shrink of the noncreep-fed calves on the day of weaning and shipping was 4.9 lb and 7.0 lb less (P<.05) than that of the energy and protein creep-fed calves, respectively. Postweaning daily gains of the energy creep-fed calves was higher than those of both the protein creep-fed calves (P=.09) and the noncreep-fed calves (P<.01) by 0.3 lb and 0.5 lb, respectively. The energy creep-fed calves consumed more (P<.05) daily dry matter than the protein creep-fed and unsupplemented calves. Little difference was observed in postweaning feed conversion among creep treatments.


Effect Of Limited-Creep Feeding On Performance Of Spring-Born Calves: Results Of 1988 Field Trials, D.D. Simms, Gerry L. Kuhl Jan 1989

Effect Of Limited-Creep Feeding On Performance Of Spring-Born Calves: Results Of 1988 Field Trials, D.D. Simms, Gerry L. Kuhl

Kansas Agricultural Experiment Station Research Reports

Two field trials were conducted to evaluate limited-creep feeding of spring- born calves using pelleted creep rations with either 0.5, 5, or 10% salt. Average daily gain was increased (P<.05) over controls in trial 2 and when both trials were combined. However, intakes were higher than desired and feed conversion much poorer than expected.

Visual Body Condition Score Of Cows, C.K. Clarke, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Condition scores are often used to describe the "fleshiness" of cows. These scores range from 1 (extremely emaciated) to 9 (extremely fat).


Limit Versus Full Creep-Feeding Of A High Protein Supplement To Calves Grazing Late Summer Bluestem, R.C. Cochran, C.E. Binns, L.R. Corah, T. Delcurto, E.S. Vanzant Jan 1989

Limit Versus Full Creep-Feeding Of A High Protein Supplement To Calves Grazing Late Summer Bluestem, R.C. Cochran, C.E. Binns, L.R. Corah, T. Delcurto, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Limit creep-feeding a 36% protein supplement (avg. salt concentration = 7.9%) was compared with unlimited consumption of the same supplement without salt (full creep-feeding) and with no supplementation. Average daily gain of steer calves was increased (P≤.06) by.19 (limit creep-feeding) and .38 (full creep-feeding) lb per day compared with non-supplemented calves. Average daily gain of heifer calves was not increased by creep feeding. Efficiency with which creep was converted to extra gain was poor for both limit and full creep-feeding groups. Little difference was observed in postweaning average daily gains; however, the calves given ad libitum access to ...


Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby Jan 1989

Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Intensive-early stocking (lES) in the Kansas Flint Hills has greatly increased livestock production efficiency. The potential for grazing of regrowth on IES pastures the following winter was studied by mowing different plots on a monthly basis from October to April, 19831985. Winter herbage removal had no significant effect on herbage production in the following seasons or on the total nonstructural carbohydrates (TNC) of big bluestem (Andropogon gerardii) rhizomes. Since there was no reduction in herbage yield for any mowing date, cattle producers can apparently restock IES pastures after October 1.


Influence Of Level Of Grain Supplementation On The Performance Of Intensive-Early Stocked Steers, R.C. Cochran, E.S. Vanzant, Clenton E. Owensby Jan 1989

Influence Of Level Of Grain Supplementation On The Performance Of Intensive-Early Stocked Steers, R.C. Cochran, E.S. Vanzant, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Two levels of sorghum grain supplementation (2 or 4 lb/day) for"¢steers in an intensive-early stocking program tended to increase average daily gain in direct proportion to increasing supplement level (2.7 and 2.9 lb/day. respectively, compared to 2.5 lb with no supplement). Similarly, grass remaining in the pastures after the cattle were removed on July 15, and at the end of the growing season on October 1, was greater when cattle were supplemented.


Performance Of Stocker Steers Grazing Smooth Bromegrass At Two Stocking Rates And Dewormed With Morantel Tartrate, K.P. Coffey, Joseph L. Moyer, Lyle W. Lomas Jan 1989

Performance Of Stocker Steers Grazing Smooth Bromegrass At Two Stocking Rates And Dewormed With Morantel Tartrate, K.P. Coffey, Joseph L. Moyer, Lyle W. Lomas

Kansas Agricultural Experiment Station Research Reports

Early-intensive grazing of smooth bromegrass reduced animal gains but improved gain/acre. Morantel tartrate reduced fecal nematode egg counts but had no effect on animal performance at either stocking rate


Evaluation Of Wheat Middlings As A Supplement For Cattle Consuming Winter Range Forage, G.D. Sunvold, R.C. Cochran, E.S. Vanzant, S.D. Brandyberry, R.B. Hightshoe, T. Delcurto Jan 1989

Evaluation Of Wheat Middlings As A Supplement For Cattle Consuming Winter Range Forage, G.D. Sunvold, R.C. Cochran, E.S. Vanzant, S.D. Brandyberry, R.B. Hightshoe, T. Delcurto

Kansas Agricultural Experiment Station Research Reports

Intake of dormant, bluestem-range forage was increased by feeding steers supplements based on wheat middlings or soybean meal + sorghum grain, although the degree of influence on forage intake depended on type and level of supplementation. All supplements increased (P<.10) total diet digestibility. However, fiber digestibility tended to be slightly lower for steers receiving the high level of wheat middlings and the soybean meal + sorghum grain supplement.


Influence Of Supplemental Protein Concentration On Intake, Utilization, And Quality Of Diet Selected By Steers Grazing Dormant Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, A.A. Beharka, E.S. Vanzant Jan 1989

Influence Of Supplemental Protein Concentration On Intake, Utilization, And Quality Of Diet Selected By Steers Grazing Dormant Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, A.A. Beharka, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Fifteen ruminally and 12 esophageally cannulated steers were randomly assigned to receive low (LP), moderate (MP), and high (HP) crude protein (CP) supplements in a 23-day winter grazing trial designed to evaluate dormant tallgrass forage intake and utilization. Supplemental CP levels were 13, 26, or 39%, respectively. Forage organic matter (OM) intake was greatest (P<.05) for the MP steers. Likewise, fiber (NDF) digestibility and ruminal fill were largest (P<.10) for the MP treatment. Furthermore, the quality of diet selected tended to improve with increasing supplemental protein concentration. Increasing CP concentration in supplements dramatically improves the intake and utilization of dormant forage. In this study, intake and digestibility were optimized with the MP supplement.


Soybean Meal+Sorghum Grain, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Supplements For Beef Cows Grazing Dormant, Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, E.S. Vanzant Jan 1989

Soybean Meal+Sorghum Grain, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Supplements For Beef Cows Grazing Dormant, Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Eighty-six pregnant. Hereford x Angus cows were randomly assigned to one of three winter supplement treatments: 1) soybean meal+sorghum grain, 2) alfalfa hay, or 3) dehydrated alfalfa pellets. Cows supplemented with dehydrated alfalfa pellets gained more (P<.05) weight during gestation and lost the least (P<.05) weight at calving. However, no differences (P>.10) were detected in cow body condition change. reproductive efficiency, or calf growth.


Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant Jan 1989

Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Incorporation of rumen bypass fat into a supplement to be fed with low quality forage did not affect total dry matter digestibility or ruminal dry matter fill. Similarly, no difference in digestibility was observed among types (animal vs. plant) or levels (low vs. high) of lipids used in this study. Rumen bypass fat apparently avoids the negative impact on forage utilization seen with conventional fats.


Effect Of Inoculants And Npn Additives On Dry Matter Recovery And Cattle Performance: A Summary Of 22 Trials, K.K. Bolsen, A. Laytimi, Ronald V. Pope, Jack G. Riley Jan 1989

Effect Of Inoculants And Npn Additives On Dry Matter Recovery And Cattle Performance: A Summary Of 22 Trials, K.K. Bolsen, A. Laytimi, Ronald V. Pope, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

Results from 22 trials comparing dry matter (DM) recovery and cattle performance of inoculated or non-protein nitrogen (NPN)-treated silages to controls were summarized using paired t-test analysis. Inoculants consistently improved DM recoveries and gains per ton of crop ensiled in both com and forage sorghums. The use of NPN adversely affected nutrient preservation and gain per ton of crop ensiled, particularly for the wetter forage sorghums.


Additive-Treated Corn And Forage Sorghum Silages For Growing Cattle, K.K. Bolsen, A. Laytimi, R.A. Hart, F. Niroomand, J. Hoover Jan 1989

Additive-Treated Corn And Forage Sorghum Silages For Growing Cattle, K.K. Bolsen, A. Laytimi, R.A. Hart, F. Niroomand, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Whole-plant corn silages were treated with Ecosyl® or Foraform® in one trial and Biomate® or Biomate + Cold-flo® in the second trial. In both trials, the silages were well preserved, but all were highly unstable in air during the first 3 to 4 weeks of the feed-out period. Foraform-treated silage was 2 to 6 degrees F cooler than its control, but Cold-flo-treated silage was 2 to 8 degrees F warmer during the first 10 days post-filling. Laboratory silo results showed that both control silages fermented extremely fast; however, inoculated silages had slightly lower pH and higher lactic acid values through the ...


Effect Of Commercial Inoculants On Fermentation Of 1988 Silage Crops, K.K. Bolsen, A. Laytimi, S. Azimi, R.A. Hart, F. Niroomand, J. Bradford, L. Clare Jan 1989

Effect Of Commercial Inoculants On Fermentation Of 1988 Silage Crops, K.K. Bolsen, A. Laytimi, S. Azimi, R.A. Hart, F. Niroomand, J. Bradford, L. Clare

Kansas Agricultural Experiment Station Research Reports

We have measured silage fermentation dynamics in over 50 crops since the development of a 4 x 14 inch PVC pipe, laboratory-scale silo in 1984. In many of these experiments, our objective was to determine how inoculants or inoculant/enzyme combinations affected the rate and efficiency of the ensiling process. Twenty-five different inoculants have been tested over a wide range of ensiling conditions. Results show that the majority of silage inoculants available today are able to supply a high number of lactic acid bacteria (LAB) and to improve silage fermentation in most crops (KAES, Reports of Progress 494, 514, and ...


Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale Jan 1989

Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale

Kansas Agricultural Experiment Station Research Reports

Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and restricting the fermentations, as expected, in alfalfa and corn. In both forage sorghum hybrids, although the ensiling process was delayed about 24 hours by the Foraform treatment, end-product silages had lower pH values and equal or higher lactic acid levels than untreated silages. Foraform was effective at both 60 to 90 F temperatures in alfalfa, with treated silages having lower lactic and acetic acids, ethanol, and ...


Evaluation Of Interseeded Grain Sorghum And Soybeans As A Silage Crop, S.H.M. Esmail, H. Hartadi, L.H. Harbers, John E. Shirley, J.D. Hoover, S. Azimi, L.W. Pfaff, K.K. Bolsen Jan 1989

Evaluation Of Interseeded Grain Sorghum And Soybeans As A Silage Crop, S.H.M. Esmail, H. Hartadi, L.H. Harbers, John E. Shirley, J.D. Hoover, S. Azimi, L.W. Pfaff, K.K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Interseeded grain sorghum and soybeans have been evaluated as a silage crop over a 3year period. In the first 2 years, maximum dry matter (DM) yields occurred at the late-dough stage of the grain sorghum, and interseeded silages had higher crude protein (CP) and acid detergent fiber contents than non-interseeded late-dough stage, grain sorghum control silages. In year 2, seeding grain sorghum and soybeans in alternating IS-inch rows increased DM yield, CP content, and the proportion of soybean plants in the mixture compared to drilled (6-inch spacing) interseeding. Digestibilities of most nutrients were similar in all silages; however, cattle fed ...


Influence Of Plant Parts On In Vitro Dry Matter Disappearance Of Forage Sorghum Silages, J. White, K.K. Bolsen Jan 1989

Influence Of Plant Parts On In Vitro Dry Matter Disappearance Of Forage Sorghum Silages, J. White, K.K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Five mid- to late- season forage sorghum hybrids were used to plot the changes in silage in vitro dry matter disappearance (IVDMD) when their proportions of grain, leaf, sheath, and stalk were altered. The average IVDMD of the parts were: grain 76.9%, leaf 57.7%, sheath 52.7%, and stalk 60.8 percent. The grain proportion had a large positive effect on silage IVDMD dynamics, whereas the sheath plant part had a negative effect.


Near-Infrared Reflectance Spectroscopy Calibrations For Sorghum Silage, P.C. Dubois, G. Garcia, K.K. Bolsen, L.H. Harbers Jan 1989

Near-Infrared Reflectance Spectroscopy Calibrations For Sorghum Silage, P.C. Dubois, G. Garcia, K.K. Bolsen, L.H. Harbers

Kansas Agricultural Experiment Station Research Reports

Calibrations for near-infrared reflectance spectroscopy (NIRS) analysis of sorghum silage and sheep feces samples were developed. with mixed success. For sorghum silage, the standard errors of calibration (SEC) and correlation coefficients of calibration (R2) for crude protein (CP) were .405% and .927; for acid detergent fiber (ADF), 1.667% and .943; and for neutral detergent fiber (NDF), 1.589% and .964, respectively. The statistics for crude protein were not as good as similar work reported in the literature, but the data for the fiber components was as good as or better than similar reported work. For sheep feces. the SEC ...


Dietary Influences On Pancreatic Amylase And Small Intestinal Disaccharidase Activities In Cattle, K.K. Kreikemeier, D.L. Harmon, K. Gross, C. Armendariz Jan 1989

Dietary Influences On Pancreatic Amylase And Small Intestinal Disaccharidase Activities In Cattle, K.K. Kreikemeier, D.L. Harmon, K. Gross, C. Armendariz

Kansas Agricultural Experiment Station Research Reports

Pancreatic α-amylase activity was 54% higher in cattle fed at twice maintenance energy than in cattle fed at maintenance and was 52% greater in hay-fed than grain-fed cattle. Increased pancreatic α-amylase activity probably represents increased secretion as well. α-amylase activity in small intestinal digesta was greater with increased energy intake and with hay feeding. Small intestine mucosal disaccharidase activities in cattle were unaffected by diet. Lactase activity was highest in the proximal segment of the small intestine and low in both mid and distal segments. Maltase and isomaltase activities were low in the duodenum, but increased toward the jejunum and ...


Impact Of Cash Settlement On Feeder Cattle Hedging Risk, J.R. Mintert, Ted C. Schroeder Jan 1989

Impact Of Cash Settlement On Feeder Cattle Hedging Risk, J.R. Mintert, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

One of the principal motivations for the introduction of cash settlement in feeder cattle futures contracts was to reduce basis risk. This study examined expected changes in hedging risk attributable to the adoption of cash settlement. The estimates of cash settlement futures hedging risks were generally small than estimates of hedging risks using the physical-delivery futures. The reduction in hedging risk was greatest for feeder steers meeting futures contract weight specifications, but reductions were also common for other weight classes and for heifers.


A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner Jan 1989

A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Starting 3 days postmortem, sections from eight USDA Choice or better, yield grade 4, strip loins were dry-aged (aged unpackaged) or vacuum-aged (aged in vacuum bags) for an additional 11 days. The dry-aged loins lost more (P<.05) weight during aging than vacuum-aged loins, and cooked faster, with less (P<.05) cooking loss than the unaged loins. Vacuum-and dry-aged samples were similar (P>.05) in tenderness, and both were more tender (P<.05) than unaged counterparts. A trained taste panel found no differences in subcutaneous fat flavor. However, lean from the vacuum-aged samples had a more intense sour flavor note and more intense bloody/serumy flavor and metallic notes than either of the other treatments. The lean of dry-aged samples was beefier and had more brown/roasted flavor than vacuum-aged or unaged counterparts.
