Effects Of Ph, Myoglobin Form, And Endpoint Temperature On Cooked Ground Beef Color, M.K. Schoenbeck, Donald H. Kropf, Melvin C. Hunt, S. Hawthorne, Sally L. Stroda
Kansas Agricultural Experiment Station Research Reports
Beef quadriceps muscles from nine pH groups (5.5 - 6.4 in .1 increments) were ground; mixed with fat (20%); formed into patties whose myoglobin was in either the oxy or deoxy state; and cooked to four endpoint temperatures (150, 160, 170, or 180°F). Internal cooked patty color was evaluated visually and instrumentally. Patties containing deoxymyoglobin with pH 6.2 or higher and cooked to 150 and 160°F were redder visually and instrumentally than those with a lower pH. Similar trends, but not as pronounced, were observed with patties containing oxymyoglobin. Deoxymyoglobin was more resistant to denaturation and, thus, made patties more …

As much as 53% free fatty acids in choice white grease did not adversely affect piglet performance. Thus, concentration of free fatty acids, if they are not otherwise damaged or rancid, is not an acceptable measure of fat quality.; Swine Day, Manhattan, KS, November 16, 2000
In Vitro Degradation Of Betaine By Ruminal Microbes, C.A. Löest, C.K. Armendariz, Evan C. Titgemeyer
In Vitro Degradation Of Betaine By Ruminal Microbes, C.A. Löest, C.K. Armendariz, Evan C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
An in vitro study was conducted to evaluate the degradation of betaine sources by rumen microbes. Five sources of betaine (anhydrous betaine, betaine-HCl, feed-grade betaine, lipidcoated betaine, and concentrated separator byproduct) were incubated in rumen fluid collected from steers fed grain- or forage-based diets. In vitro degradation of betaine was slower with the high roughage diet than the grain diet. Betaine from concentrated separator by-product was degraded most rapidly, but no large differences occurred among the other four sources. The disappearance of betaine from lipid-coated product indicates that it did not resist ruminal degradation. Although betaine from all sources was …

Effects Of Dystocia And Confined Calving On Calf-Morbidity Rate From Birth To Weaning, M.W. Sanderson, D.A. Dargatz
Kansas Agricultural Experiment Station Research Reports
An analysis was performed on data from a national survey of US beef cow-calf producers to quantify the effects of management factors on calf-morbidity risk from birth to weaning. The analysis included 2,490 herds from 23 states. A high calf-morbidity herd was defined as one with greater than 10% morbidity. The rate of dystocia in the herd was categorized into five levels. All dystocia levels were associated significantly with increased risk of being a high calf-morbidity herd. Having greater than 70% of cows and heifers calve in confinement also was associated with increased risk of being a high calf-morbidity herd. …

A Survey On The Use Of Blade Tenderizers By Beef Fabrication Plants, C.D. George-Evins, John A. Unruh, James L. Marsden, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
A questionnaire to determine the use of blade tenderizers in beef fabrication facilities was sent to 241 members of the North American Meat Processors Association (NAMP). Eighty-four percent of the 90 respondents used blade tenderizers. These subprimals were at least sometimes tenderized by the following percentages of respondents: tenderloins, 7.9; chuck cuts, 18; round cuts, 36; ribeyes, 38; strip loins, 56; and top sirloin butts, 62. If a processor blade-tenderized a particular cut, they tenderized a majority of their production for that cut, generally with multiple passes through the tenderizer. For example, the 62% of respondents who tenderized top sirloin …

Kansas Agricultural Experiment Station Research Reports
Two studies were conducted to evaluate the effects of spray-dried blood meal and its pH on nursery pig performance. Spray-dried blood meal pH decreases as storage time increases prior to spray drying. In Exp. 1, addition of 2.5% spray-dried blood meal to the diet improved ADG and ADFI in nursery pigs (15.4 lb to 35.9 lb), but did not influence feed efficiency. In Exp. 2, the inclusion of 5% spray-dried blood meal improved feed efficiency without affecting ADG or ADFI. The pH (7.4 to 5.9 in Exp. 1 and 7.6 to 5.9 in Exp. 2) of the blood meal did …

Effects Of Frequency Of Supplementation On Performance Of Beef Cows Grazing Winter Pasture, C.G. Farmer, R.C. Cochran, D.D. Simms, E.A. Klevesahl, T.A. Wickersham
Kansas Agricultural Experiment Station Research Reports
One hundred twenty spring-calving Hereford x Angus cows grazing low-quality tallgrass-prairie forage during the winter of 1998 were fed a 43% crude protein supplement 2, 3, 5, or 7 days a week. Supplement was fed at 4 lb/head daily to cows supplemented daily. The other cows still received 28 lb per week but divided equally among feedings. Cumulative performance (measured by changes in body condition score and body weight) was slightly better with increased supplementation frequency. However, the magnitude of differences in body condition and body weight changes, even for the most extreme treatment comparisons, were relatively small.
Effects Of Cattle Grazing Crop Residues On Soil Bulk Density, R.K. Taylor, John W. Slocombe
Effects Of Cattle Grazing Crop Residues On Soil Bulk Density, R.K. Taylor, John W. Slocombe
Kansas Agricultural Experiment Station Research Reports
Effects of cattle grazing on soil bulk density were measured at two sites in central Kansas. Samples were taken at depths of 0 to 3 in. and 3 to 6 in. from grazed and ungrazed areas at five locations in each field. No statistical difference (P>0.01) between bulk densities of the two areas occurred at the 3 to 6 in. depth for either site. However, soil in the grazed areas had significantly higher (P<0.01) bulk density than that in the ungrazed areas at the 0 to 3 in. depth at both sites.

Kansas Agricultural Experiment Station Research Reports
A 43% CP (dry basis) supplement was fed to 16 ruminally fistulated steers on 2, 3, 5, or 7 days a week. Supplement was offered at .36% BW (dry basis) daily for steers that received supplement every day. For other treatments, the same amount of supplement was split equally among supplementation events. Forage intake and digestibility increased with increasing supplementation frequency. However, the difference in forage intake tended (cubic, P=.07) to be most prominent for the two extremes; the 3- and 5-days-a-week treatments tended to be similar. Forage intake for steers supplemented on 2 days a week decreased on the …

Effects Of Grazing System On Performance Of Cow-Calf Pairs Grazing Bermudagrass Pastures Interseeded With Wheat And Legumes, Lyle W. Lomas, Joseph L. Moyer, K.P. Coffey, George A. Milliken
Kansas Agricultural Experiment Station Research Reports
A total of 96 fall-calving cows and 64 calves grazed bermudagrass interseeded with wheat and legumes during 1996, 1997, and 1998 in either a continuous or rotational system stocked at equal rates. Legume cover, available forage dry matter, residual hay production, gains of cows and calves grazing wheat interseeded into bermudagrass, and gains of cows grazing bermudagrass interseeded with legumes were measured. Grazing system had no effect on legume cover, available forage dry matter, gains of cows and calves (wheat phase), and gains of cows (legume phase); however, rotationally grazed pastures produced more residual hay than those grazed continuously.
Integrated Control Of Sericea Lespedeza In Kansas, Walter H. Fick
Integrated Control Of Sericea Lespedeza In Kansas, Walter H. Fick
Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted near Maple Hill, KS in 1998 to compare the effectiveness of herbicides and mowing used alone and in combination for control of sericea lespedeza (Lespedeza cuneata). Remedy® at 0.5 lb/acre was more effective when applied during the vegetative growth stage (>87%) than during flowering or seed production. Ally® at 0.4 oz/acre provided control equivalent to Remedy and was equally effective at both the vegetative and bloom stages. Both herbicides provided less than 60% control when applied during seed production. A single mowing on July 8 was not effective. Mowing followed in 6 weeks by Remedy …

Kansas Agricultural Experiment Station Research Reports
One hundred sixty-four crossbred beef steers were used in a 102-day growing study to determine optimum levels of alfalfa hay in limit-fed, high-energy, growing diets. Diets contained steam-flaked corn and 40% Sweet Bran® brand wet corn gluten feed (dry matter basis) with 0, 10, or 20% ground alfalfa hay. A fourth diet containing steam-flaked corn (no Sweet Bran) and 20% ground alfalfa hay was used as a control. Average daily gains and feed efficiencies in the growing phase were greater (P<.05) for cattle fed no alfalfa than for cattle fed the control, 10% alfalfa, or 20% alfalfa diets. Steers fed the control and 20% alfalfa diets had increased rates of dry matter intake (P<.05) compared to those fed no alfalfa. At the end of the growing phase, all cattle were placed on a common finishing diet and fed for 101 days. Dry matter intakes during the finishing phase for cattle previously fed no alfalfa were numerically less than intakes for cattle fed other diets and significantly less than intakes for cattle previously fed the control diet. Feed efficiencies were greater for cattle previously fed 20% alfalfa diets than those fed the control diet (P<.05). Average daily gains did not differ (P>.40) among diets during the finishing phase.

Effects Of Carnitine On Performance Of Finishing Steers, R.H. Greenwood, C.A. Löest, Evan C. Titgemeyer, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Ninety-five crossbred steers (787 lb initial body weight) were fed finishing diets (14.5% crude protein) for 129 days. Diets were based on steam-flaked corn and contained 6% alfalfa and 4% tallow. Steers were supplemented with 2 g per day of L-carnitine, or not supplemented (control). Feed intakes, gains, and feed efficiencies were not impacted by carnitine supplementation. However, steers receiving L-carnitine had fatter carcasses as indicated by tendencies (P<.2) for more subcutaneous fat, higher marbling scores, and higher yield grades. Carnitine supplementation may increase fat deposition and alter carcass quality of finishing cattle.

A 152-day experiment was conducted using 615 crossbred steers to evaluate cattle performance when steam-flaked corn in finishing diets was replaced partially with wet corn gluten feed (CGF). Finishing diets contained no wet CGF (0CGF) or 30 and 60% CGF on a dry matter basis (30CGF and 60CGF). Ruminal and fecal pH increased linearly (P<.01) as the proportion of wet corn gluten feed increased. Cattle fed 60CGF gained less than those fed 30CGF (P<.01) and were less efficient than cattle fed 0CGF or 30CGF (P<.05). Dressing percentage was lower (P<.03) for cattle fed 60CGF compared to cattle fed 30CGF. Incidence of liver abscesses increased linearly (P<.01) as the level of CGF increased. Replacing steamflaked corn with wet CGF at 30% of the diet did not alter performance.

One hundred sixty-four crossbred beef steers were used to determine optimal Rumensin ® concentrations in limit-fed, high-energy, growing diets. Diets contained 30, 40, or 50 grams of Rumensin per ton of dry matter (R30, R40, and R50). Average daily gain and feed efficiency during the growing phase were not different (P>.80) among treatments. Steers that received R50 in the growing phase had the highest average daily gains during the finishing phase (P<.05). This resulted in heavier carcass weights for R50 than R30 (P<.05) and R40 (P<.12). Feed efficiencies during the finishing phase were not different among treatments (P>.40).
Effects Of High-Grain Or High-Roughage Transition Diets On Finishing Performance Of Cattle Previously Fed High-Concentrate Growing Diets, Sean P. Montgomery, J.J. Sindt, T.B. Farran, H.J. Labrune, R.D. Hunter, James J. Higgins, T.A. Nutsch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports
Three hundred twenty-eight crossbred beef steers previously fed high-concentrate growing diets had ad libitum access to one of two transition diets prior to initiation of the finishing phase. Transition diets consisted of 58% steam-flaked corn and 30% alfalfa hay or of 23% steamflaked corn and 65% alfalfa hay (DM basis). Average daily gains, dry matter intakes, and feed efficiencies during the transition phase were greater for steers fed the high-grain diet than for steers fed the high-roughage diet (P<.01). This resulted in heavier carcass weights at the end of the subsequent finishing phase for steers fed the high-grain transition diet (P<.05). Average daily gains and feed efficiencies in the finishing phase were not affected by the type of diet fed during the transition phase (P>.20).

Effects Of Late-Summer Protein Supplementation On Stocker Cattle Performance, Feedlot Gain, And Carcass Traits, T.T. Marston, D.O. Yauk, L.E. Wankel, J.F. Gleghorn
Kansas Agricultural Experiment Station Research Reports
A 2-year trial was conducted to study the effects of feeding an Arsoy™-based, 32% crude protein supplement to stocker cattle grazing late-summer native pastures. During about 90 days of late-summer/fall grazing, the steers efficiently converted the Arsoy supplement (5.3:1, as fed basis) into significantly greater weight gains (55 lb) relative to nonsupplemented contemporaries. Both groups of steers then were finished and slaughtered in commercial facilities to determine if the supplementation program had any carryover effects. Late-summer supplementation did not influence steers' feedlot gain or carcass traits including ribeye area, fat thickness, and quality grade. However, average hot carcass weight and …

Kansas Agricultural Experiment Station Research Reports
Blood glucose levels of finishing cattle were measured between 3 and 30 days prior to slaughter and compared to performance and carcass traits. In trial 1, blood samples were obtained from 318 heifers at 2 hours postfeeding at 30 days before slaughter. Plasma glucose levels were correlated positively with fat thickness (P<.01) and kidney, pelvic, and heart fat (P<.02). Trial 2 utilized 72 steers from which blood was collected at 15 hours postfeeding at 3 days before slaughter. Blood glucose was correlated positively with average daily gain (P<.01); dry matter intake (P<.01); hot carcass weight (P<.01); ribeye area (P<.01); fat thickness (P<.06); and kidney, pelvic, and heart fat (P<.01). A third trial was conducted with 77 individually fed steers to determine if blood glucose levels could be used to predict finishing performance and carcass traits. Contrary to trials 1 and 2, plasma glucose did not reflect performance or carcass traits except marbling score (P<.03).

Refractive Index: A Rapid Method For Determination Of Starch Availability In Grains, J.J. Sindt, Sean P. Montgomery, T.B. Farran, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Steam-flaked corn samples were used in a series of experiments to determine if refractive index could be used as a rapid, inexpensive method to predict starch availability. Results were best when samples were incubated for 15 min with 500 to 600 active units of enzyme/gm of grain prior to measuring on a hand-held refractometer. Correlations to starch availability determined from gas production by a commercial lab were R=.64 for whole flakes and R=.79 when samples were ground. Samples of corn flaked to different densities produced estimates of solubility similar to an in situ dry matter disappearance assay (R2 = .84, …

Drylot Receiving Program Vs Pasture Conditioning With Micotil® Metaphylaxis For Grazing Stocker Calves, S.I. Paisley, Thomas R. Falkner, F.K. Brazle, Gerald L. Stokka
Kansas Agricultural Experiment Station Research Reports
Three stocker cattle field studies were conducted comparing a traditional 4- to 5-week drylot receiving program with injectable antibiotics administered on a pull-and-treat basis versus a pasture-based conditioning program using an initial metaphylaxis with Micotil® followed by immediately placing cattle on grass. Although daily gains were similar (P=.80) for both receiving programs during the first 28 days, pasture conditioning reduced the number of cattle treated and increased (P<.01) daily gains during the subsequent grazing phase.
