Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer
Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda 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
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.
Predicting Voluntary Forage Intake In Cattle, C.A. Bandyk, R.C. Cochran
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 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
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.

Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation, 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 …

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 …
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
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.
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
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. Total …
Prevalence, Antibiotic Susceptibility, And Genetic Diversity Of Salmonella, Campylobacter, And Escherichia Coli O157:H7 Collected At Four Kansas Beef Cattle Feedyards Over 13 Months, D.R. Hyatt, J.C. Galland, S. Crupper, L. Hawkins, N.V. Anderson, Gerald L. Stokka
Prevalence, Antibiotic Susceptibility, And Genetic Diversity Of Salmonella, Campylobacter, And Escherichia Coli O157:H7 Collected At Four Kansas Beef Cattle Feedyards Over 13 Months, D.R. Hyatt, J.C. Galland, S. Crupper, L. Hawkins, N.V. Anderson, Gerald L. Stokka
Kansas Agricultural Experiment Station Research Reports
Salmonella, Campylobacter, and Eschericia coli O157:H7 are important foodborne pathogens, but longitudinal studies of their prevalence in beef cattle feedyards have not been done. Our long- term study involved 24,556 samples taken from beef cattle feedyards found overall prevalence's of 4.87% for Salmonella, 20.1% for Campylobacter in hospital pen fecal samples, and 0.20% for E. coli O157:H7. Yard and pen differences (P<0.05) were detected. All 53 E. coli O157:H7 isolates were resistant to Talmicosin and Erythromycin, two antimicrobials used in food animal medicine. Their genetic diversity was high and did not indicate the presence of resident strains at the yards studied. Salmonella, Campylobacter, and E. coli O157:H7 were probably brought into the yards by shipments of new cattle. Many of these organismswere susceptible to antibiotics commonly used to treat beef cattle.

Soybean Hulls In Roughage-Free Diets For Limit-Fed Growing Cattle, C.A. Löest, D.J. Bindel, Evan C. Titgemeyer, James S. Drouillard, Dale A. Blasi
Kansas Agricultural Experiment Station Research Reports
Three hundred heifers (573 lb initial body weight) were used in a growing study to compare growth performance of cattle fed roughage-free diets comprised mainly of soybean hulls with that of cattle receiving roughage- and corn-based diets and to determine if cattle fed soybean hull-based diets would respond to supplemental methionine hydroxy analogue (MHA; a source of methionine), ruminally protected betaine, or concentrated separator by-product (CSB; a source of betaine). Treatments included 1) a roughage-based diet fed at 2.75% of body weight (ROUGH), 2) a corn-based diet fed at 1.5% of body weight (CORN1.5), 3) a corn- based diet fed …
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
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.

Betaine As A Dietary Supplement For Finishing Cattle, C.A. Loest, R.D. Hunter, R.H. Wessels, James S. Drouillard, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
One hundred seventy five steers (902 lb initial body weight) were used in a finishing study to determine the effect of betaine, provided either as feed-grade betaine (Betafin-S6, Finnsugar Bioproducts) or as concentrated separator by-product (CSB; desugared beet molasses), on animal performance and carcass characteristics. Steers were fed a finishing diet based on steam-flaked and dry-rolled corn. Treatments included 10.5 or 21 g/steer daily supplemental feed-grade betaine or 250 g (15.5 betaine) or 500 g (31 g betaine) of CSB per steer daily. Dry matter intakes increased (linear, P<0.1) for steers supplemented with feed- grade betaine. Average daily gains and feed efficiencies were not affected by treatments. Dressing percent and twelfth rib back fat increased (P<0.1) for steers that received feed-grade betaine. Rib-eye area decreased (P<0.1) when steers were supplemented with either feed-grade betaine or CSB. Yield grades were significantly higher (linear, P<0.1) for cattle receiving supplemental CSB or feed-grade betaine (quadratic, P<.05). Hot carcass weights, KPH, marbling scores, and percentage of carcasses grading USDA Choice were not affected by supplemental betaine. In this study, betaine supplementation did not markedly alter growth performance, but carcass fatness tended to increase for both supplements.
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
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.
Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones
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.
Comparison Of Implants In Grazing Heifers And Carryover Effects On Finishing Gains And Carcass Traits, F.K. Brazle
Comparison Of Implants In Grazing Heifers And Carryover Effects On Finishing Gains And Carcass Traits, F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
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).

Characteristics Of Pelleted Wheat Middlings That Affect Summer Storage, Carl R. Reed, Dionisia M. Trigo-Stockli, Dale A. Blasi, Fred J. Fairchild
Kansas Agricultural Experiment Station Research Reports
Pelleted wheat middlings samples were collected from four Kansas flour mills in March, April, and May, 1997 to characterize their moisture content and bulk density as they would be purchased directly from the mills by a livestock producer. The average moisture content of pelleted wheat middlings was 14% as they left the mills but declined during the spring to 13.6%. Pellets purchased from Kansas mills during the summer months are likely to contain 13.0 to 13.5% moisture. The average bulk density was approximately 40 lb/ft3 , which is equivalent to about 50 lb/bu. Based on the equilibrium moisture contents determined …
Fusobacterium Necrophorum In Ruminal Contents And On The Ruminal Wall Of Cattle, K.R. Bedwell, N. Wallace, Tiruvoor G. Nagaraja
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.

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, but …

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.
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
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.

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 …
Effect Of Date Of Harvest On The Nutritional Quality Of Native Grass Hay, J.C. Baker, S.R. Tonn, David E. Kehler, Dale A. Blasi
Effect Of Date Of Harvest On The Nutritional Quality Of Native Grass Hay, J.C. Baker, S.R. Tonn, David E. Kehler, Dale A. Blasi
Kansas Agricultural Experiment Station Research Reports
Native grass hay meadows in three Kansas Flint Hills counties were sampled at 2-week intervals during the growing season to determine the effect of harvest date on forage quality. Each sample was analyzed for crude protein (CP), acid detergent fiber (ADF), and phosphorus (PHOS). CP and PHOS contents declined, and ADF increased as harvest date progressed into the growing season. Both CP and ADF were related highly to harvest date. PHOS content was associated only moderately with harvest date. Harvest date of native grass hay can significantly influence supplemental protein needs for beef cows.

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 …
