Effects Of Increasing Amounts Of Supplemental Soybean Meal On Intake And Digestibility Of Tallgrass-Prairie Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson Jan 1998

Effects Of Increasing Amounts Of Supplemental Soybean Meal On Intake And Digestibility Of Tallgrass-Prairie Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson

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.


Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja Jan 1998

Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of supplemental carbohydrate sources on the utilization of low- quality forage in continuous "artificial rumen" culture. Providing readily digestible carbohydrates (starch, glucose, and fiber) did not improve total diet digestion. In fact, starch and glucose depressed fiber digestion. Response to other simple sugars was variable.


Predicting Voluntary Forage Intake In Cattle, C.A. Bandyk, R.C. Cochran Jan 1998

Predicting Voluntary Forage Intake In Cattle, C.A. Bandyk, R.C. Cochran

Kansas Agricultural Experiment Station Research Reports

A large database was compiled of forage intake observations published during the past 20 years. Inputs included a wide range of factors believed to be related to voluntary intake. An analysis was designed to pinpoint which feed and animal characteristics were most valuable in predicting voluntary intake across a range of feeding situations and to compare the ability of different models to predict intake. Results emphasized the complexity of intake prediction. A wide range was evident in the variables included in the optimal models for predicting intake within different data subsets. In many cases, we observed that ratios between feed ...


Effects Of Processing Whole-Plant Corn Silage On Growth Performance And Nutrient Digestibility In Feedlot Cattle, T.J. Wistuba, M.K. Siefers, J.E. Turner, G.L. Huck, K.K. Bolsen, Matthew A. Young, Ronald V. Pope Jan 1998

Effects Of Processing Whole-Plant Corn Silage On Growth Performance And Nutrient Digestibility In Feedlot Cattle, T.J. Wistuba, M.K. Siefers, J.E. Turner, G.L. Huck, K.K. Bolsen, Matthew A. Young, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Sixty crossbred heifers and 12 crossbred steers were used to evaluate the effects of mechanically processing (crushing the kernels of) whole-plant corn silage on feedlot performance and nutrient digestibility. The three treatments were: preensiled processed, postensiled processed, and nonprocessed corn silages. Heifers fed the processed corn silages grew faster and were more efficient than those fed nonprocessed silage. Steers consuming the two processed silage rations had numerically higher DM, OM, NDF, and ADF digestibilities and significantly higher starch digestibilities than those fed the non- processed silage ration. These data suggest that processing whole-plant corn silage before or after ensiling has ...


Site Of Semen Deposition And Fertility In Lactating Beef Cows Synchronized With Gnrh And Pgf2Α, G.C. Lamb, K. E. Thompson, K. Anderson, David M. Grieger, Timothy G. Rozell, Jeffrey S. Stevenson Jan 1998

Site Of Semen Deposition And Fertility In Lactating Beef Cows Synchronized With Gnrh And Pgf2Α, G.C. Lamb, K. E. Thompson, K. Anderson, David M. Grieger, Timothy G. Rozell, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

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 ...


Fusobacterium Necrophorum Leukotoxoid Vaccine For Prevention Of Liver Abscesses, S. Saginala, K.F. Lechtenberg, Kenneth E. Kemp, P.M. Hine, Tiruvoor G. Nagaraja, M. M. Chengappa Jan 1998

Fusobacterium Necrophorum Leukotoxoid Vaccine For Prevention Of Liver Abscesses, S. Saginala, K.F. Lechtenberg, Kenneth E. Kemp, P.M. Hine, Tiruvoor G. Nagaraja, M. M. Chengappa

Kansas Agricultural Experiment Station Research Reports

The efficacy of Fusobacterium necrophorum crude leukotoxoid vaccine to immunize and protect steers against experimentally induced liver abscesses was evaluated. The vaccine consisted of cell-free culture supernatant of a high leukotoxin-producing strain of F. necrophorum, inactivated with formalin and homogenized with an oil emulsion adjuvant. Vaccine was injected subcutaneously on days 0 and 21. Blood samples were collected weekly to monitor immune response. Three weeks after the second vaccination, steers were injected intraportally with F. necrophorum culture to induce liver abscesses. Three weeks later (day 63), steers were euthanatized and necropsied; livers were examined, and protection was assessed. Anti-leukotoxin antibody ...


Comparison Of Fusobacterium Necrophorum Isolates From Liver Abscesses, Ruminal Walls, And Ruminal Contents Of Feedlot Cattle, Sanjeev K. Narayanan, O. Okwumabua, J. Staats, Richard D. Oberst, Tiruvoor G. Nagaraja, M. M. Chengappa Jan 1998

Comparison Of Fusobacterium Necrophorum Isolates From Liver Abscesses, Ruminal Walls, And Ruminal Contents Of Feedlot Cattle, Sanjeev K. Narayanan, O. Okwumabua, J. Staats, Richard D. Oberst, Tiruvoor G. Nagaraja, M. M. Chengappa

Kansas Agricultural Experiment Station Research Reports

DNA finger printing (restriction fragment length polymorphism analysis) was employed to genetically compare Fusobacterium necrophorum isolates of liver abscesses, ruminal wall, and ruminal contents from the same animal. Fusobacterium necrophorum isolates from liver abscesses were genetically identical to the corresponding isolates from the ruminal wall in eight of nine animals tested. This genetic similarity between the isolates supports the hypothesis that F. necrophorum in liver abscesses originates from the ruminal wall.


Effect Of Tylosin On Ruminal Fusobacterium Necrophorum Population And Fermentation Products In Cattle Fed A High-Grain Diet, N. Wallace, Y. Sun, Kenneth E. Kemp, J.C. Parrott, Tiruvoor G. Nagaraja Jan 1998

Effect Of Tylosin On Ruminal Fusobacterium Necrophorum Population And Fermentation Products In Cattle Fed A High-Grain Diet, N. Wallace, Y. Sun, Kenneth E. Kemp, J.C. Parrott, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Tylosin feeding prevented the increase in Fusobacterium necrophorum population normally associated with the feeding of a high-grain diet. Also, tylosin appeared to moderate the ruminal fermentation during initial adaptation to a high-grain diet.


Effects Of Ruminally Protected Choline And Dietary Fat On Performance Of Finishing Heifers, D.J. Bindel, R.H. Wessels, C.A. Loest, James S. Drouillard, Evan C. Titgemeyer Jan 1998

Effects Of Ruminally Protected Choline And Dietary Fat On Performance Of Finishing Heifers, D.J. Bindel, R.H. Wessels, C.A. Loest, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

A 120-day finishing study utilizing 318 heifers (753 lb initial body weight) examined the effects of ruminally protected choline in diets with no tallow or 2 or 4% of supplemental tallow. Heifers were fed a finishing diet based on a mix of steam-flaked and dry- rolled corn; encapsulated choline (20, 40, or 60 g/head/day, supplying 5, 10 or 15 g choline/head/day) was top-dressed to the diet or not added. Dry matter intake decreased linearly with inclusion of fat (P<.05) but was not affected significantly by addition of choline. Daily gains also decreased linearly (P<.05) with fat addition. Choline supplementation increased gain (linear, P<.1; qua dratic, P<.05), with the greatest increase occurring for the first 20 g increment encapsulated choline/day. Likewise, feed efficiency improved (P<.1) with supplemental choline. Again, the greatest response occurred for the first 20 g/day. Kidney, pelvic, and heart fat and yield grade both increased linearly (P<.1) with fat supplementation. The percentage of carcasses grading USDA Choice decreased (linear, P<.05; quadratic, P<.1) when choline was added at 60 g/day. Hot carcass weight, marbling, dressing percent, and 12th rib fat thickness were not affected significantly by either fat or choline. Ruminally protected choline can improve average daily gain and feed efficiency of finishing cattle.


Molasses-Fat Blend As An Energy Source And Conditioning Agent In Feedlot Diets, A.S. Flake, Gerry L. Kuhl, James S. Drouillard Jan 1998

Molasses-Fat Blend As An Energy Source And Conditioning Agent In Feedlot Diets, 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.


Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Low-Quality Brome Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer Jan 1998

Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Low-Quality Brome Hay, 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

The effects of increasing levels of degradable intake and digestion of low-quality brome hay were evaluated using 16 ruminally fistulated beef steers. Trends were evident for small, positive changes in total intake and digestion with increasing level of DIP supplementation. As a result, total digestible to feeding forage to provide .041, .082, and OM intake (TDOMI) increased with DIP supplementation but tended to plateau below the highest supplementation level.


Impact Of Increasing Amounts Of Supplemental High-Protein Soybean Meal On Performance Of Range Beef Cows, C.P. Mathis, R.C. Cochran, B.C. Woods, J.S. Heldt, K. C. Olson, David M. Grieger Jan 1998

Impact Of Increasing Amounts Of Supplemental High-Protein Soybean Meal On Performance Of Range Beef Cows, C.P. Mathis, R.C. Cochran, B.C. Woods, J.S. Heldt, K. C. Olson, David M. Grieger

Kansas Agricultural Experiment Station Research Reports

One hundred and twenty spring-calving Hereford x Angus cows grazing low-quality, tallgrass-prairie forage were fed 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, or 6.0 lb soybean meal (SBM) per head daily. SBM as a source of supplemental degradable intake protein (DIP) can be effective in maintaining cow body weight and body condition during the winter grazing season. Performance as measured by changes in body weight and condition score was maximized when cows received approximately 3.5 to 3.8 lb/day. Below this level, cows lost about 48 lb (about .4 units ...


Effect Of Supplemental Carbohydrate Source On The Utilization Of Low-Quality Tallgrass-Prairie Hay By Beef Steers, J.S. Heldt, R.C. Cochran, C.G. Farmer, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja Jan 1998

Effect Of Supplemental Carbohydrate Source On The Utilization Of Low-Quality Tallgrass-Prairie Hay By Beef Steers, J.S. Heldt, R.C. Cochran, C.G. Farmer, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja

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 ...


Fusobacterium Necrophorum In Ruminal Contents And On The Ruminal Wall Of Cattle, K.R. Bedwell, N. Wallace, Tiruvoor G. Nagaraja Jan 1998

Fusobacterium Necrophorum In Ruminal Contents And On The Ruminal Wall Of Cattle, K.R. Bedwell, N. Wallace, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Fusobacterium necrophorum was quantified from ruminal contents and ruminal wall tissue collected at slaughter. Livers were examined and scored for abscesses. The mean concentration of F. necrophorum on the ruminal wall ranged from 2.9 x 103 to 6.1x 105 per cm2 . The dorsal sac had the lowest counts, and dorsal blind and ventral sacs had the highest counts of F. necrophorum adherent to the ruminal wall. The concentrations of F. necrophorum in ruminal contents and on the ruminal wall did not appear to be related to presence or absence of abscessed livers or to severity of abscesses.


Development Of An In Vitro Procedure To Determine Ruminal Availability Of Protein, C.K. Schoenholz, James S. Drouillard, C.K. Armendariz, Evan C. Titgemeyer Jan 1998

Development Of An In Vitro Procedure To Determine Ruminal Availability Of Protein, C.K. Schoenholz, James S. Drouillard, C.K. Armendariz, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

A series of in vitro experiments was conducted to determine the ruminal availability of protein from grains. Procedures were based on assumptions that 1) ruminal availability of protein is first-limiting to microbial growth, 2) accumulation of microbial cells accurately predicts ruminal protein availability,3) cytosine can be used to accurately estimate microbial cell mass, and 4) cytosine is present in microorganisms but not in feeds. Cytosine content of in vitro cultures was measured by high performance liquid chromatography. Early experiments determined that adding 0.75 g soluble starch provided enough energy that culture growth depended on available protein. In the ...


Microbial Evaluation Of Steam Pasteurization And Comparison Of Excision Versus Sponge Sampling Recovery, D.L. Retzlaff, S.A. Rueger, Randall K. Phebus, James L. Marsden, Curtis L. Kastner Jan 1998

Microbial Evaluation Of Steam Pasteurization And Comparison Of Excision Versus Sponge Sampling Recovery, 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 ...


Evaluation Of Changes In Microbial Populations On Beef Carcasses Resulting From Steam Pasteurization, T.L. Brown, P.E. Peters, Donald H. Kropf, Randall K. Phebus, Abbey L. Nutsch, Curtis L. Kastner Jan 1998

Evaluation Of Changes In Microbial Populations On Beef Carcasses Resulting From Steam Pasteurization, T.L. Brown, P.E. Peters, Donald H. Kropf, Randall K. Phebus, Abbey L. Nutsch, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

The steam pasteurization process (SPS 400) developed by Frigoscandia Food Process Systems (Bellevue, WA) was effective in reducing bacterial populations in both laboratory and commercial settings. The objective of steam pasteurization and other meat decontamination measures is to extend product shelf life and improve safety by inhibiting or inactivating pathogens, while at the same time maintaining acceptable meat quality characteristics. The effects of steam pasteurization on beef carcass bacterial populations were evaluated at two large commercial beef processing facilities. A shelf-life study also was conducted to determine the microbial profiles of vacuum packaged beef loins from pasteurized and non-pasteurized carcasses ...


Prevalence Of Escherichia Coli O157:H7 In Cow-Calf Herds In Kansas, J.M. Sargeant, J.R. Gillespie, D.R. Hyatt, J.C. Galland, L.K. Bohra, Richard D. Oberst, Randall K. Phebus, Michael P. Hays Jan 1998

Prevalence Of Escherichia Coli O157:H7 In Cow-Calf Herds In Kansas, J.M. Sargeant, J.R. Gillespie, D.R. Hyatt, J.C. Galland, L.K. Bohra, Richard D. Oberst, Randall K. Phebus, Michael P. Hays

Kansas Agricultural Experiment Station Research Reports

Fecal samples from cows and calves and samples of water sources were collected monthly for 8 months from 10 Kansas cow-calf farms to determine the prevalence of E. coli O157:H7. The bacterium was found in 8% of fecal samples from cows that were within 24 hours of calving, 1.4% of fecal samples from cows which were not within 24 hours of calving, 1.4% of calf fecal samples, and 1.5% of water samples. E. coli O157:H7 was identified from at least one sample on all farms.


Wheat Middlings In Roughage-Based Or Limit-Fed, High-Concentrate Diets For Growing Calves, Gerry L. Kuhl, R.H. Wessels, Dale A. Blasi, James S. Drouillard Jan 1998

Wheat Middlings In Roughage-Based Or Limit-Fed, High-Concentrate Diets For Growing Calves, Gerry L. Kuhl, R.H. Wessels, Dale A. Blasi, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

A 101-day growing study was conducted to evaluate the growth performance of beef heifers fed wheat middlings in traditional full- fed, sorghum silage-based rations and in limit-fed, high-concentrate rations. Diets were formulated without wheat middlings or with wheat middlings replacing 33, 67, or 100% of rolled corn plus soybean meal. Daily gains decreased linearly (P<.01) with increasing levels of wheat middlings in the roughage-based diets because of lower feed intake (P<.10), but feed efficiency was not affected (P>.30). For the limit-fed diets, heifer daily gains decreased linearly (P<.01) as the proportion of wheat middlings in the diet increased, resulting in a linear reduction (P<.01) in feed efficiency. Wheat middlings can be utilized effectively as the predominant energy/protein source for growing cattle, though their nutritional and economic value, relative to corn and soybean meal, may be different for roughage-based and limit-fed diets.

Control Of Escherichia Coli O157:H7 In Large-Diameter, Lebanon-Style Bologna, K.J. Karr, Curtis L. Kastner, James L. Marsden, Randall K. Phebus

Kansas Agricultural Experiment Station Research Reports

Lebanon bologna raw batter was mixed with a five-strain mixture of Escherichia coli O157:H7 to achieve average inoculum levels of 7.79, 7.77, and 7.92 log CFU/g as deter mined on MSA, 202, and PRSA media, respectively. Treatment 1 consisted of a fermentation cycle of 8 hrs at an internal temperature (I.T.) of 80EF then 24 hrs at 100EF I.T., followed by 24 hrs at 110EF I.T. Treatments 2, 3, and 4 included additional heating at 115EF I.T. for 1, 2, and 5 hrs, respectively. All heat treatments resulted in product that ...


Effects Of Added Fat, Degradable Intake Protein, And Ruminally-Protected Choline In Diets Of Finishing Steers, A.S. Flake, Gerry L. Kuhl, James S. Drouillard Jan 1998

Effects Of Added Fat, Degradable Intake Protein, And Ruminally-Protected Choline In Diets Of Finishing Steers, A.S. Flake, Gerry L. Kuhl, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

A total of 216 yearling steers was used in two finishing experiments to evaluate interactions between levels of dietary fat, protein and ruminally protected choline. In Trial 1, steers received diets that combined levels of 0% or 5% added fat (choice white grease), 10.8% or 12.5% crude protein, and 0 or 5 grams per head daily of ruminally protected choline. Steers were fed in pens of five head each for 89 days. Adding fat decreased intake (P<.01), average daily gain (P<.1), and carcass weight (P<.07) and increased carcass yield grade (P<.06) but did not alter feed efficiency (P>.9). Increasing the protein level from 10.8 to 12.5% had no significant effects on live animal performance, but the ...


Influence Of Melengesterol Acetate (Mga®) And Implus-H® Implants On Rate Of Gain, Feed Efficiency, And Carcass Characteristics Of Culled Beef Cows Fed A High Concentrate Ration, M.F. Spire, J.C. Galland, John A. Unruh, James S. Drouillard Jan 1998

Influence Of Melengesterol Acetate (Mga®) And Implus-H® Implants On Rate Of Gain, Feed Efficiency, And Carcass Characteristics Of Culled Beef Cows Fed A High Concentrate Ration, M.F. Spire, J.C. Galland, John A. Unruh, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

No statistical differences were detected in feedlot performance or carcass traits between control culled beef cows and those that were treated with melengesterol acetate (MGA®) and/or Implus-H® when fed in a feedyard for 56 days before slaughter. All groups performed well, indicating that this practice may be used to improve the market value of culled cows. Cow health during the feeding period is a major concern.


Price Discovery Issues For Fed Cattle, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder Jan 1998

Price Discovery Issues For Fed Cattle, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Interviews were conducted with cattle feeders, beef packers, and others involved in the beef industry to discern their concerns about fed-cattle price discovery. Three issues predominated. First was the need to better identify beef quality, ideally by objective means. Quality often, but not always, referred to tenderness and the "eating experience" of consumers. Second was the need for greater pricing accuracy, signaling a desire for less average pricing and more value-based pricing. The need for improved market information was the third issue identified.


Grid Pricing Of Fed Cattle, Ted C. Schroeder Jan 1998

Grid Pricing Of Fed Cattle, 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 ...


Projecting Fed Cattle Price Discovery Over The Next Decade, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder Jan 1998

Projecting Fed Cattle Price Discovery Over The Next Decade, J. Mintert, C.E. Ward, D.S. Peel, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

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.


Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones Jan 1998

Differences In Efficiency Among Kansas Beef Cow Producers, 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.


Effects Of Feeding Rumensin® In A Mineral Mixture On Steers Grazing Native Grass Pastures, F.K. Brazle, S.B. Laudert Jan 1998

Effects Of Feeding Rumensin® In A Mineral Mixture On Steers Grazing Native Grass Pastures, 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.


Effects Of Base Ingredient In Cooked Molasses Blocks On Intake And Digestion Of Prairie Hay By Beef Steers, R.H. Greenwood, Evan C. Titgemeyer, James S. Drouillard Jan 1998

Effects Of Base Ingredient In Cooked Molasses Blocks On Intake And Digestion Of Prairie Hay By Beef Steers, 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 ...

A Three-Year Economic Evaluation Of A Commercial Heifer Development Program, G.C. Lamb, J.M. Lynch, B.L. Miller, V. Traffas, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

In 1994, 1995, and 1996, a commercial heifer development operation purchased a total of 1542 potential replacement heifers. Heifers were purchased in the fall proceeding the spring breeding season and fed a silage-based diet during the developmental period. Before the breeding season began, heifers that failed to meet minimum requirements for pelvic area, average daily gain, body weight, disposition, or structural soundness were culled. During the first year, 42% of 483 heifers were culled, 17% of 468 heifers were culled in the second year, and 14% of 591 heifers in the third year. Estrus was synchronized and heifers were inseminated ...
