Use Of Cystorelin® And Artificial Insemination In Repeat-Breeding Beef Heifers After Estrous Synchronization, J.P. Holz, P.L. Houghton, M.F. Spire
Kansas Agricultural Experiment Station Research Reports
Gonadotropin-releasing hormone (GnRH) was administered to a group of 13- to 14- month-old Angus and Angus crossbred repeat-breeding heifers at the time of the second or third artificial insemination to determine its effect on conception rates. Little benefit was derived from the use of GnRH at either second or third service in highly developed repeat-breeding heifers.

Effect Of Density Of Steam Flaked Milo On Animal Performance, Mill Production Rate, And Subacute Acidosis, Robert T. Brandt Jr., A.S. Freeman, T.P. Eck, Christopher D. Reinhardt, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
In Trial 1, 336 yearling steers (755 lb) were fed diets containing milo flaked to 22 (L), 25 (M), or 28 (H) lb/bu. The steers fed L consumed 3.2% less dry matter than cattle fed H (P<.05) and had 6.9% lower gains (P<.05). Feed efficiency tended (P=.15) to favor cattle fed H. The H milo was flaked 27% faster than M and 67% faster than L (P<.0001), resulting in lower production cost for the heavy flakes. In Trial 2, six ruminally cannulated steers were fed the same diets used in Trial 1 in a replicated 3x3 Latin square. After adaptation to the respective diets, the cattle were fasted and then overfed to simulate a drastic intake fluctuation. The L diet was fermented more rapidly than the H diet, resulting in greater ruminal pH depression (P<.10) following overconsumption. Under the conditions of this experiment, flaking milo more intensively than 28 lb/bu (58.7% starch gelatinization) resulted in decreased consumption, lower mill efficiency, and increased propensity for acidosis in finishing steers.
Effect Of Bacterial Inoculants On The Preservation Of Alfalfa And Whole-Plant Corn Silages, K.K. Bolsen, R.N. Sonon, B.S. Dalke
Effect Of Bacterial Inoculants On The Preservation Of Alfalfa And Whole-Plant Corn Silages, K.K. Bolsen, R.N. Sonon, B.S. Dalke
Kansas Agricultural Experiment Station Research Reports
Inoculated and control alfalfa and corn silages were compared in pilot-scale silos. Inoculated silages for both crops had higher lactic acid contents and DM recoveries and lower values for pH, acetic acid, ethanol, and ammonia-nitrogen than controls"”evidence that the inoculants produced a more efficient fermentation. These results are consistent with numerous studies that compared untreated and inoculant-treated silages over a wide range of crops and ensiling conditions in our research during the past several years.
Effect Of Supplemental Fat And Thermal Stress On Nitrogen And Energy Metabolism Of Finishing Heifers, Robert T. Brandt Jr., J.E. Williams, Timothy J. Jones
Effect Of Supplemental Fat And Thermal Stress On Nitrogen And Energy Metabolism Of Finishing Heifers, Robert T. Brandt Jr., J.E. Williams, Timothy J. Jones
Kansas Agricultural Experiment Station Research Reports
Twelve British and British crossed heifers fed whole shelled corn finishing diets were used in a 2 x 2 factorially arranged experiment to study the main effects of and interactions between feeding supplemental tallow (0 vs 4%) and thermal heat stress (55°F vs 90°F). Heifers were maintained in temperature- and humidity-controlled environmental rooms. Neither supplemental fat or thermal stress affected dry matter intake or total tract digestibility of organic matter, starch, NDF, or ADF. However, heat stress elevated water consumption (P<.01) and rectal temperature (P<.01). When fed at equal intakes, heifers consuming tallow-supplemented diets retained more (P<.05) nitrogen, and tallowsupplemented diets had a higher (P=.08) ME value than non-tallow diets; these effects were not observed when heifers were fed ad libitum. Adding tallow to diets of finishing cattle may help maintain performance under circumstances where feed intake is restricted.
Reproductive Performance Of Yearling Beef Heifers After Estradiol Benzoate And Estrous Synchronization, R.P. Bolze, C.W. Peters
Reproductive Performance Of Yearling Beef Heifers After Estradiol Benzoate And Estrous Synchronization, R.P. Bolze, C.W. Peters
Kansas Agricultural Experiment Station Research Reports
Injectable estradiol (estradiol benzoate) was evaluated for its effect on the reproductive performance of yearling beef heifers whose estrous cycles were synchronized using the melengestrol acetate/prostaglandin F 2 α (MG- 2 A®/PG) system. Estradiol was injected 40 h after prostaglandin. Heifers were inseminated artificially (AI) 12 h after first observed heat during a 35-d AI period followed by 28 d of bull exposure. Estradiol had no effect on heat response or first-service pregnancy rate to AI during the synchronized period (5 d) and had no significant effect on overall AI pregnancy rate (35 d), cumulative pregnancy rate (63 d), or …
Comparison Of Synovex-S® And Two Levels Of Revalor-S® In Heavy-Weight Holstein Steers, Gerry L. Kuhl, D.D. Simms, Dale A. Blasi, Curtis L. Kastner
Comparison Of Synovex-S® And Two Levels Of Revalor-S® In Heavy-Weight Holstein Steers, Gerry L. Kuhl, D.D. Simms, Dale A. Blasi, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
In two field trials, 434 Holstein steers averaging 849 lbs were assigned randomly to three single implant treatments: 1) Synovex- S®, 2) Revalor®-S 120 (120 mg trenbolone acetate (TBA) + 24 mg estradiol), and 3) Revalor®-S 140 (140 mg TBA + 28 mg estradiol). Revalor-implanted steers gained .05 to .10 lb per day faster, but this improvement was not statistically significant (P>.05). Both Revalor-implanted groups produced trimmer carcasses with less (P<.05) backfat than Synovex steers. All other carcass characteristics and beef sensory properties, including taste panel evaluations of tenderness, juiciness, and flavor, were not influenced by implant used.

Sequential Implant Strategies With Synovex-S® And Trenbolone Acetate-Containing Implants In Calf-Fed Holstein Steers, D.D. Simms, Gerry L. Kuhl
Kansas Agricultural Experiment Station Research Reports
In a commercial feedyard trial, 242 Holstein steer calves averaging 378 lb were used to compare effects of six alternative implant programs, consisting of sequential use of Synovex-S® or a combination of estradiol and trenbolone acetate (Revalor-S® or Finaplix- S® plus Synovex-S®), on feedlot performance and carcass characteristics. The calves were implanted three times at 78- to 90-day intervals while on feed an average of 252 days. The combination implant increased (P<.05) gain by .13 to .21 lb per day in all three implant periods compared to Synovex alone. Total feedlot gain was increased in direct relation to the number of times steers received the combination implant. However, marbling score and the percentage of carcasses grading USDA Choice tended to be reduced with repeated use of Revalor or Finaplix.
Effect Of Mass Medication On The Health And Gain Of Calves In Grass Paddocks Or Feedlot Pens, F.K. Brazle
Effect Of Mass Medication On The Health And Gain Of Calves In Grass Paddocks Or Feedlot Pens, F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Four hundred and ninety mixed-breed, long-hauled, bull calves averaging 275 lb were used in a winter study to determine whether mass medicating calves in grass paddocks or feedlot pens would reduce health problems and improve performance. All calves were started in feedlot pens for 3 days, then half of the calves were turned out into grass paddocks. Mass medication with injectable oxytetracycline did not improve health or gain of the calves. Calves housed in grass paddocks during the recurring period had less sickness (P<.01), fewer (P<.05) sick days per animal purchased, and lower (P<.05) drug treatment costs than their counterparts housed in feedlot pens.
Management Of Stable Flies In Cattle Feedlots With Releases Of Parasitic Wasps, G.L. Greene, J.E. Cilek
Management Of Stable Flies In Cattle Feedlots With Releases Of Parasitic Wasps, G.L. Greene, J.E. Cilek
Kansas Agricultural Experiment Station Research Reports
During 1992, adult stable fly populations were sampled in 25 Kansas feedlots. A native stable fly parasitic wasp, Spalangia nigroaenea, was released in 19 of these feedlots. Stable fly populations were reduced up to 48% and parasite emergence was increased 21% when compared with feedlots where S. nigroaenea was not released. The percentage of total parasites that were S. nigroaenea nearly doubled in the release feedlots, compared to the nonrelease feedlots. This parasitic wasp has shown considerable promise for stable fly control in cattle feedlots. Overall, sampling and parasite costs averaged 32 cents per animal for the season.

Kansas Agricultural Experiment Station Research Reports
Alfalfa silages were made in pilot- and farm-scale silos, and five sealing treatments were compared. After 90 days, sealing dramatically reduced DM losses at the 5 and 10 in. depths in the farm silos and at the 0 to 12, 12 to 24, and 24 to 36 in. depths in the pilot silos. Extending the storage period to 180 days in pilot silos had no effect on DM losses for sealed or delay sealed silages, but DM losses for unsealed silages continued to increase at all three depths. Placing a roof over the unsealed, farm-scale silo increased the silage DM …

A Laboratory System For Modeling Hay Storage, W.K. Coblentz, J.O. Fritz, K.K. Bolsen
Kansas Agricultural Experiment Station Research Reports
A simple system is described that uses a hinged metal baling unit and a hydraulic press to make 4.0 x 4.3 x 5.3 inch wire-tied, laboratory- scale, hay bales. A comparison of densities of conventional, small, alfalfa bales (15x18x37 inches) and laboratory bales was made over a wide range of moisture levels (15 to 36%) and conventional bale densities (10 to 25 lb/ft3). Laboratory bale densities were regressed against conventional bale densities and agreement was excellent. The system is inexpensive to build and easy to use and can be reproduced easily.

Storage Losses In Net-Wrapped, Large, Round Bales Of Alfalfa Hay, R.K. Taylor, D.L. Kueck, C.E. Addison, Dale A. Blasi, Thomas Mark Maxwell, James P. Shroyer
Kansas Agricultural Experiment Station Research Reports
Net- and twine-wrapped alfalfa hay bales were stored from July, 1990 to April, 1991 in three Kansas counties (Reno, Saline, and Stafford). Dry matter losses and changes in acid detergent fiber and acid detergent insoluble nitrogen levels during storage were not significantly different between net- and twine-wrapped bales. Although a significant difference in dry matter recovery between inside and outside bale storage occurred in Saline County, it was not considered important because all recoveries were high. No significant differences in ADF or ADIN increases were found between initial core samples and samples from the outer 4 in. of the bales …

Preservation Of Alfalfa Hay With A Microbial Inoculant, R.K. Taylor, W.C. Mahanna, Dale A. Blasi, Thomas Mark Maxwell, James P. Shroyer
Kansas Agricultural Experiment Station Research Reports
Eleven large, round, alfalfa bales were treated with Pioneer® Brand 1155 Alfalfa Hay Inoculant and nine bales were untreated. The initial baling moistures were 14.1% (low) or 17.6% (medium). No significant differences were found in dry matter recovery or changes in acid detergent fiber, neutral detergent fiber, and acid detergent insoluble nitrogen levels during the 2-month storage period. Average temperature was highest in the medium moisture bales, but was not high enough to cause heat damage. The microbial inoculant did not improve preservation or quality of the alfalfa hay at the baling moistures used in this study.
Summer Annual Forages In South Central Kansas, William F. Heer, Dale A. Blasi, Dale L. Fjell
Summer Annual Forages In South Central Kansas, William F. Heer, Dale A. Blasi, Dale L. Fjell
Kansas Agricultural Experiment Station Research Reports
Six summer annuals and three forage sorghums were evaluated for forage yield and quality under south central Kansas dryland conditions. When cut in the late boot to early heading stage, all forage types (millet, sudan, sorghum-sudan, and forage sorghum) produced similar dry matter yields, with no consistent differences in nutritional quality. Allowing the forages to reach maturity prior to cutting increased total yield per acre but decreased the crude protein content. The millets were higher in protein at maturity than the sudans or forage sorghums. However, the forage sorghums produced the most mature forage, whereas common sudan yielded the least. …
Value-Added Beef Processing: Increasing The Value Of Beef Shanks Using Baadertm Processing Technology, R.E. Campbell, Melvin C. Hunt
Value-Added Beef Processing: Increasing The Value Of Beef Shanks Using Baadertm Processing Technology, R.E. Campbell, Melvin C. Hunt
Kansas Agricultural Experiment Station Research Reports
Using a BaaderTM desinewing machine on beef shanks can increase the value of a beef carcass by $1 to $5 by improving palatability and texture and reducing fat. By varying belt pressure and drum opening size and passing shanks twice through the desinewer, we obtained commercially acceptable yields. Maximum lean yield was 93% of the shank using 5 mm drum holes for both passes. With 3 mm drum holes, very lean produced on the first pass. Using desinewed lean and flaking the sinew with an Urschel Commitrol®, we produced low-fat (10%) ground beef patties. Patties from desinewed lean alone and/or …
Comparison Of Conventional And Laboratory-Scale Alfalfa Hay Bales In Small Haystacks, W.K. Coblentz, J.O. Fritz, K.K. Bolsen
Comparison Of Conventional And Laboratory-Scale Alfalfa Hay Bales In Small Haystacks, W.K. Coblentz, J.O. Fritz, K.K. Bolsen
Kansas Agricultural Experiment Station Research Reports
A system for making laboratory-scale alfalfa hay bales was evaluated in two trials. In the first, conventional rectangular and laboratory-scale bales were made at each of seven different combinations of moisture and density. Laboratory bales were incubated between two parent conventional bales of identical moisture content and bale density. Laboratory bales remained different (P<.05) from parent conventional bales for most temperature-related storage traits. Agreement between bale types was better for most quality traits. To achieve closer agreement between bale types, a second experiment was conducted in which the laboratory bales were made at 1.0, 1.3, 1.6, and 2.0 times the density of the conventional bales. Agreement improved between laboratory bales of higher densities and conventional bales for most temperature traits. High-density laboratory bales had significantly greater acid detergent insoluble nitrogen values than conventional bales, particularly at the highest moisture level. These results implicate bale density as an important factor in heat damage to proteins in alfalfa hay.

Progesterone Concentrations, Estrous Response, And Fertility In Beef Heifers After Estrous Synchronization Using Melengestrol Acetate® And Prostaglandin F2Α, C.W. Peters, Robert L. Larson, L.R. Corah
Kansas Agricultural Experiment Station Research Reports
Melengestrol acetate (MGA®) and prostaglandin F2α(PG; Lutalyse®) were used to synchronize estrus in 757 yearling, virgin, beef heifers on six commercial ranches. Heifers were inseminated artificially (AI) 12 h after first detected estrus; those not detected in estrus were time-inseminated 72 h post-PG injection. Heifers detected in estrus by 72 h had higher AI and overall pregnancy rates than their counterparts not detected in estrus. Heifers with serum progesterone>1 ng/ml at PG administration were generally more fertile than those with progesterone<1 ng/ml. Of the heifers not detected in estrus and with low progesterone (<1 ng/ml), 24% still conceived to the timed insemination at 72 h, but only 73% became pregnant during the entire breeding period. Overall AI conception rate, based on estrous detection and timed insemination, was 49% and varied from 24% to 69% among the six ranches. Heifers exhibiting estrus and with elevated (>1 ng/ml) serum progesterone showed acceptable pregnancy rates (63% AI and 94% overall).

Can "Natural" Flavorings Enhance The Flavor Of Low-Fat Ground Beef?, C.F. Carmack, Melvin C. Hunt, Donald H. Kropf, J.R. Schwenke, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
Natural flavorings were evaluated for use in low-fat ground beef, which frequently lacks flavor intensity. Three lean sources, A-maturity (young), E-maturity (mature cow), and imported (cow) beef round muscles, were used to formulate 7% and 25% fat ground beef. A-maturity fat was added to adjust fat levels. Controls (no added flavors) were prepared for each lean source. No additives were used in 25% fat controls, but 7% fat controls contained water (10%), carrageenan (.5%), and encapsulated salt (.38%). Four "natural" flavorings; Dried Cream Extract (DCE, Cumberland Packing Co., Inc.); Natural Prime Beef Base WONF #224545 and #224546 (224545, 224546, Tastemaker); …

Effect Of Protein Concentration In Supplements And Frequency Of Supplementation On The Performance Of Beef Cows Grazing Dormant Bluestem Range, J.L. Beaty, R.C. Cochran, E.S. Vanzant, J.L. Morrill, Robert T. Brandt Jr., D.E. Johnson
Kansas Agricultural Experiment Station Research Reports
One hundred twenty-eight, pregnant, Angus x Hereford cows were used to determine whether response to altering frequency of winter range supplementation depends on the protein concentration in the supplements. Supplements containing 12%, 21%, 31%, or 41% crude protein (CP) were fed either daily (7X) or three times weekly (3X). Both groups consumed 31 lbs of supplement per head weekly. Frequency of supplementation exerted only minor influences on cow performance and had no effect on calf performance. However, cows lost less body weight and condition as CP concentration in the supplement increased. In addition, calf weaning weights were improved with increasing …
Use Of Visual Appearance As An Indicator Of Degree Of Doneness In Ground Beef Patties, K.E. Warren, Melvin C. Hunt, M.A. Hague, Donald H. Kropf, Sally L. Stroda
Use Of Visual Appearance As An Indicator Of Degree Of Doneness In Ground Beef Patties, K.E. Warren, Melvin C. Hunt, M.A. Hague, Donald H. Kropf, Sally L. Stroda
Kansas Agricultural Experiment Station Research Reports
Outbreaks of food-borne illness have emphasized the need for proper cooking of ground beef patties. Because of difficulties in measuring internal temperature of ground beef patties, visual indicators usually are used to estimate degree of doneness. As internal temperature increases from 130 to 170 ÌŠF, the internal appearance is expected to change from very red to brown and juice color from red to clear. Based on ground beef patties from three sources, we found that internal color over-estimated internal temperature. Expressible juice decreased in redness as internal temperature increased but did not run clear even at temperatures over 160 ÌŠF. …

Large Round Bale Hay Wastage By Various Feeding Methods, R.K. Taylor, G.W. Warmann, B.M. Plaschka, Dale A. Blasi, Glenn E. Newdigger Jr.
Kansas Agricultural Experiment Station Research Reports
The amounts of wheat or hybrid sudan hay wasted with three large round bale feeding methods were evaluated at two ranch locations. The feeding methods were: 1) bale processor (Hay Forage Industries BP 25®) used to shred forage into bunks; 2) the same processor used to shred forage onto the ground; and 3) unrolling large round bales on the ground. Estimated forage wastages or refusals from unrolling, shredding onto ground, and shredding into bunks were 23, 13, and 8% with wheat hay and 22, 16, and 11% with sudan hay, respectively. These results demonstrate the potential for substantial savings of …

Kansas Agricultural Experiment Station Research Reports
In 1992, 24 corn hybrids were grown under both irrigated and dryland conditions and were harvested at 90% of the kernel milk line. Growing condition and hybrid significantly affected plant height and the number of days to the tasseling and silking stages. Most dryland hybrids had higher dry matter (DM) contents than irrigated hybrids, but all 24 hybrids had higher grain yields under irrigation. Growing condition and hybrid also significantly affected whole-plant DM and stover yields and percentages of cob and stover. The grain portion made the greatest contribution to the higher whole-plant silage yields for the irrigated hybrids compared …

Luteinizing Hormone Release And Plasma Metabolites In Mature, Ovariectomized Beef Cows Fed Various Lipid Diets, C.W. Peters, L.R. Corah, R.C. Cochran
Kansas Agricultural Experiment Station Research Reports
Feeding rumen-escape lipid or soybean oil in a range supplement to beef cow resulted in elevated blood cholesterol and enhanced luteinizing hormone (LH) release compared to a control (milo and soybean meal) supplement. Cholesterol was elevated (P<.01) within 14 d of lipid feeding. The amplitude of each LH pulse and maximal pulse height were greater (P<.05) when cows were fed high-lipid diets. The positive influence of high-lipid diets on reproductive function may be explained in part by enhanced LH release.

Kansas Agricultural Experiment Station Research Reports
Eight ruminally cannulated steers were used to determine digestion characteristics of soybean meal/sorghum grain supplements containing 12%, 20%, 30%, or 39% crude protein (CP) fed either daily (7X) or three times weekly (3X). The basal forage was wheat straw. Weekly supplement intake was the same per week (30.5 lb) for both frequency groups. The effect of feeding supplements differing in protein concentration on wheat straw intake and dry matter digestibility (DMD) did not depend on frequency of supplementation. Increased frequency of supplementation resulted in greater intake of straw, although DMD was slightly depressed. Increasing protein concentration in the supplements was …

Kansas Agricultural Experiment Station Research Reports
In 1989, two Pioneer corn hybrids, 3377 and 3389, were grown under irrigation and harvested at 80% milk line kernel maturity. Voluntary intakes and ADF digestibilities were similar for all hybrid, inoculant, and storage time combinations; however, DM digestibility was higher for 3377 silage than for 3389, and DM, CP, and NDF digestibilities were higher at the 50- than the 250-day storage time. The inoculant did not influence either voluntary intake or digestibility. In 1990, the same corn hybrids and DeKalb DK 42Y and Pioneer 8358 grain sorghum hybrids were grown under both irrigated and dryland conditions. Whole-plant DM contents …
Influence Of Method Of Processing Supplemental Alfalfa On Intake And Utilization Of Dormant, Bluestem-Range Forage By Beef Steers, B.A. Lintzenich, R.C. Cochran, E.S. Vanzant, J.L. Beaty, Robert T. Brandt Jr., Tiruvoor G. Nagaraja, G. St. Jean

Kansas Agricultural Experiment Station Research Reports
A digestion trial was conducted to determine the effect of method of processing supplemental alfalfa on the intake and utilization of dormant, bluestem-range forage. Supplement treatments were 1) control: no supplement; 2) ground and pelleted, suncured alfalfa; 3) ground and pelleted dehydrated alfalfa; and 4) longstem alfalfa hay. Bluestem forage intake (% BW), diet digestibility, and ruminal dry matter fill 4 hours after feeding were increased (P<.10) when supplemental alfalfa was fed, compared with no supplementation. Little difference was evident among different forms of supplemental alfalfa for most of the forage utilization characteristics measured. However, a weak trend (P=.18) was observed for increased intake of bluestem forage by the steers supplemented with dehydrated alfalfa pellets compared with suncured alfalfa pellets.

Kansas Agricultural Experiment Station Research Reports
Sixteen ruminally fistulated steers were used to study the effects of supplemental alfalfa level (.25 or 1.0% body weight [BW]) and method of processing (hay or pellets) on wheat straw utilization. Response to increased level of supplemental alfalfa did not dependent on method of processing (longstem vs pelleted) for the quality of alfalfa (22.7% CP) used in this trial. Increasing the level of alfalfa from .25 to 1.0% of BW reduced (P#.02) straw intake and diet digestibility, but increased (P<.002) digestible dry matter intake by steers. With high quality hay, ground and pelleted alfalfa elicits the same type of response as longstem alfalfa.
