Pregnancy Rates In Beef Cattle After Administration Of Gnrh Agonist 11 To 14 Days After Insemination, I. Rettmer, L.R. Corah, Jeffrey S. Stevenson
Pregnancy Rates In Beef Cattle After Administration Of Gnrh Agonist 11 To 14 Days After Insemination, I. Rettmer, L.R. Corah, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
Pregnancy rates were assessed in suckled beef cows (n=145) and virgin beef heifers (n=606) of mixed breeding following an injection of either 100 or 200 μg of a GnRH agonist given once on d 11-14 after estrus and insemination. In heifers, the 100 μg dose improved (P<.08) pregnancy rates, based on rectal palpation of the uterus, and at both doses, based on actual calving dates. There was no effect of either dose on pregnancy rates of suckled cows, based on palpation results, but actual calving showed a 21% increase (P<.08) in pregnancy rates in cows treated with 100 μg of the GnRH agonist.
Influence Of Increasing Amounts Of Supplemental Alfalfa Hay On Intake And Utilization Of Dormant, Winter-Harvested, Bluestem-Range Forage By Beef Steers, E.S. Vanzant, R.C. Cochran
Influence Of Increasing Amounts Of Supplemental Alfalfa Hay On Intake And Utilization Of Dormant, Winter-Harvested, Bluestem-Range Forage By Beef Steers, E.S. Vanzant, R.C. Cochran
Kansas Agricultural Experiment Station Research Reports
Sixteen, ruminally cannulated, beef steers were used in an intake/digestion experiment to determine the effects of supplementing a dormant, winter-harvested, bluestem range, forage diet with increasing amounts of moderate quality alfalfa. Steers were allowed ad libitum access to dormant forage and were supplemented with alfalfa hay at: 1) .23, 2) .47, 3).70, and 4) .94 % of BW on a dry matter (DM) basis. As the amount of supplemental alfalfa increased, dormant forage intake decreased, but total DM intake increased. Dry matter digestibility was unaffected by treatment, and only minor changes were noted for ruminal fermentation characteristics. Changes in ruminal …

Breed And Management System Effects On Feedlot Performance And Carcass Traits, D.T. Hickok, R.R. Schalles, D.E. Franke, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Eighty nine steers with different proportions of Angus, Hereford, Charolais, Brahman, and Gelbvieh breeding from rotational and terminal crossbreeding systems were produced in Louisiana and finished at KSU. Half of each breed group was placed in the feedlot at weaning (calves) and the other half as yearlings. Half of the each group was slaughtered at a low (0.3-0.4 in.), and the other half at high (0.5 - 0.6 in.) fat thickness. As percentage of Charolais and Gelbvieh breeding increased, feedlot performance improved. As percentage of Charolais, Gelbvieh, and Angus increased, carcass desirability improved. Steers started on feed at weaning were …

Periparturient Changes In Intake, Rumen Capacity, And Selected Blood Metabolites In Beef Cows, T.A. Stanley, R.C. Cochran, D.L. Harmon, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Four, ruminally cannulated, Hereford x Angus cows were used to study factors associated with feed intake patterns around parturition. Feed intake during the final trimester of gestation was relatively stable, in spite of a noticeable decrease in ruminal capacity. Postpartum feed intake appeared to increase, as did ruminal capacity. Blood progesterone fell after parturition, whereas estradiol did not change except for a large rise around parturition. Some plasma metabolites measured differed before and after calving; however, magnitude and patterns of change do not suggest a direct relationship with intake.
Increasing Levels Of Grain Supplementation For Intensive-Early Stocked Steers: Three-Year Summary, R.C. Cochran, Robert T. Brandt Jr., E.S. Vanzant, E.M. Clary, Clenton E. Owensby
Increasing Levels Of Grain Supplementation For Intensive-Early Stocked Steers: Three-Year Summary, R.C. Cochran, Robert T. Brandt Jr., E.S. Vanzant, E.M. Clary, Clenton E. Owensby
Kansas Agricultural Experiment Station Research Reports
During the initial 3 years of a 4-year experiment, average daily gain tended to increase in direct proportion to increasing levels of grain sorghum supplementation (2.3, 2.5 and 2.7 lb gain per day for the control and 2 and 4 lb supplement per day, respectively). The amount of grass remaining in the pastures at the end of the growing season (October 1) was greater in each of the 3 years when cattle were supplemented at 4 lb/day. During the 2 years (1989 and 1990) that feedlot performance was monitored, level of supplementation for grazing steers did not influence subsequent feedlot …
Seasonal Variation In Quality Of Grazed Forage During A Drought Year, R.C. Cochran, E.S. Vanzant
Seasonal Variation In Quality Of Grazed Forage During A Drought Year, R.C. Cochran, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Concentration of fiber in the forage selected by beef steers grazing bluestem range during a drought year (1989) was highest in the winter but declined substantially in the spring and remained fairly constant throughout summer. Conversely, crude protein concentration was lowest during the winter, peaked during the spring, declined through early summer, but increased in the late summer before declining during the fall. Precipitation was well below normal in all months except August, September, and October, which were above normal. Improvement in forage quality during those months was probably due to stimulation of late-season forage growth in response to elevated …

Effects Of Hybrid And Maturity At Harvest On Agronomic Performance Of Corn For Silage, R. Suazo, R.N. Sonon, L. Pfaff, J.T. Dickerson, K.K. Bolsen
Kansas Agricultural Experiment Station Research Reports
Twelve, commercial, corn hybrids were grown under irrigated conditions in 1990 and evaluated for agronomic and silage characteristics at three stages of maturities (1/2 milk line, black layer, and 7 days post-black layer). Time to mid-anthesis and mid-silk ranged from 62 to 68 and 65 to 70 days, respectively, and plant height ranged from 78 to 98 inches. Whole-plant dry matter (DM) content and whole-plant DM and grain yields for the 12 hybrids ranged from 23.6 to 53.7 %, 6.1 to 9.6 tons of DM per acre, and 60 to 170 bushels per acre, respectively, over the three maturities. Whole-plant …

Kansas Agricultural Experiment Station Research Reports
The performance response to a stepwise increase in the level of supplement fed to cows across the winter supplementation period was studied by feeding 112 Hereford x Angus cows the following treatments: dehydrated alfalfa pellets (DEHY) or soybean meal/grain sorghum (SS), each either level-fed (constant daily amount from December 1 to calving) or fed in a step-up program (low level from December 1 to 30; moderate level from December 31 to January 29; high level from January 30 to calving; avg = amount fed with level-feeding). Cow weight and condition changes and calf performance were favored by the step-up supplementation …
Summer Annual Forages In South Central Kansas, Dale A. Blasi, Dale L. Fjell, James P. Shroyer, Gerry L. Kuhl, William F. Heer
Summer Annual Forages In South Central Kansas, Dale A. Blasi, Dale L. Fjell, James P. Shroyer, Gerry L. Kuhl, William F. Heer
Kansas Agricultural Experiment Station Research Reports
Six, summer annual forages and three forage sorghums were evaluated for forage yield and quality under south central Kansas dryland conditions. The sudans and forage sorghums produced similar amounts of dry matter per acre, and yields for these two forage types were significantly higher than for the pearl millet cultivars tested. Conversely, the pearl millets provided higher quality forage in terms of crude protein and acid detergent fiber levels. Droughty conditions severely limited forage yields. However, forage nitrate and prussic acid levels were all relatively low, indicating the utility of raising the cutter bar to avoid harvesting the lower stalks …

Effects Of Maturity At Harvest And Cultivar On Agronomic Performance Of Forage Sorghum And The Nutritive Value Of Selected Sorghum Silages, R.N. Sonon, R. Suazo, L. Pfaff, J.T. Dickerson, K.K. Bolson
Kansas Agricultural Experiment Station Research Reports
These studies examined the agronomic performance of 20 forage sorghum cultivars, each harvested at three stages of maturity in 1990. Whole-plant dry matter (DM) yields were highest at the late-dough stage of kernel maturity, whereas DM content and grain yields steadily increased as maturity advanced. A voluntary intake and digestion trial was conducted with 12 grain and forage sorghum silages harvested at the late-dough stage in 1989. The highest silage DM intakes and digestibilities were obtained with the high-grain yielding hybrids.
Rate And Extent Of Top Spoilage Losses Of Alfalfa Silage Stored In Horizontal Silos, J.T. Dickerson, Y. Niwa, K.K. Bolsen, B.E. Brent, C. Lin, J.E. Bradford
Rate And Extent Of Top Spoilage Losses Of Alfalfa Silage Stored In Horizontal Silos, J.T. Dickerson, Y. Niwa, K.K. Bolsen, B.E. Brent, C. Lin, J.E. Bradford
Kansas Agricultural Experiment Station Research Reports
Effects of covering, time, and depth from the surface on the rate and extent of top spoilage losses in alfalfa silages stored in horizontal silos were studied under pilot- and farm-scale conditions. Covering silages increased silage DM and nutrient recoveries, regardless of time or depth from the original surface, when compared to uncovered counterparts. Treatment x location x time interactions (P<.001) were observed for pH, lactic acid, and DM recovery in uncovered silages. By week 2 post-ensiling, significant deterioration had occurred in the top foot of uncovered silages, as evidenced by higher pH (7.36) and lower lactic acid (2.1% of the silage DM) and DM recoveries (85.6% of the DM ensiled). After week 4 post-ensiling, significant deterioration had occurred in the second foot from the surface, and it continued into the third foot after week 7. These data indicate that protecting the silage stored in the top 3 ft of horizontal silos immediately after filling should greatly increase storage efficiency.
Comparison Of Synovex-S® And Steer-Oid® In Finishing Yearling Steers, Robert T. Brandt Jr., S.J. Anderson, J.K. Elliott
Comparison Of Synovex-S® And Steer-Oid® In Finishing Yearling Steers, Robert T. Brandt Jr., S.J. Anderson, J.K. Elliott
Kansas Agricultural Experiment Station Research Reports
Synovex-S (SS) and STEER-oid (SO) were compared in a 122-d finishing study. No differences were observed over the entire study for animal performance or carcass traits. However, in the final period (d 91-122), steers implanted with SO gained 8.4% faster (P=.17) and 8.7% more efficiently (P=.10) than steers implanted with SS, suggesting that estradiol payout in this period was less diminished for SO implants. The importance of this finding is unknown, because it is generally recommended that steers fed for longer periods of time be reimplanted midway through the finishing period to maintain maximal implant response.

Timing Of Trenbolone Acetate Implants On Performance, Carcass Characteristics, And Beef Quality Of Finishing Steer Calves, G. L. Huck, Robert T. Brandt Jr., D.D. Simms, Gerry L. Kuhl, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Angus and Angus-cross calves (632 lb) were utilized in a finishing study to evaluate the effects of implanting with estradiol and progesterone (Synovex-S®) and(or) trenbolone acetate (Finaplix®) on performance of finishing steers. Over the entire finishing period (117 d), implanted steers had higher (P<.05) daily gains and were more efficient than nonimplanted steers. Carcasses from implanted cattle had heavier (P<.05) hot weights and larger (P<.05) ribeye areas. Steers implanted with Finaplix had larger (P<.05) ribeye areas than those implanted with Synovex only. Marbling scores and quality grades were not affected by implant treatments. Rib (9-10-11) sections from implanted steers were heavier (P<.05) as a result of both heavier (P<.05) bone and soft tissue weights. However, no differences in percentages of protein, fat, and moisture were detected by proximate analysis of the soft tissue. Concomitant use of Finaplix with Synovex-S did not affect performance of Angus and Anguscrossed steer calves.
Evaluation Of Revalor® Implants For Stocker-Finishing Steers, Robert T. Brandt Jr., R.J. Grant, Ronald V. Pope
Evaluation Of Revalor® Implants For Stocker-Finishing Steers, Robert T. Brandt Jr., R.J. Grant, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Revalor® implants (containing trenbolone acetate plus estradiol) were evaluated in a grazing-finishing system using steers with a known previous implant history. Grazing gains were not improved by either Ralgro® or Revalor implants, suggesting that previously implanted steers may not respond to implants during a later growing phase. During the finishing phase, steers implanted with Revalor gained 5.4 to 8.0% faster (P<.05) than steers implanted with Synovex-S®. Gain efficiency in the finishing period was improved 4.8% (P<.10) for steers receiving no pasture implant and a Revalor implant during the finishing phase (0R), compared with steers receiving Ralgro/Synovex (RS) or Revalor/Revalor (RR) implants in the pasture/feedlot phases. Steers implanted with RR had larger (P<.05) ribeye areas than RS steers, with 0R steers intermediate. However, RR steers had a 20 percentage unit reduction (P<.05) in carcasses reaching the choice grade compared to RS steers. Revalor can improve steer feedlot performance, but multiple implantation may reduce quality grade.
Monensin Levels In A Steam-Flaked Milo Finishing Diet With 4% Added Fat, Robert T. Brandt Jr., S.J. Anderson, J.K. Elliott
Monensin Levels In A Steam-Flaked Milo Finishing Diet With 4% Added Fat, Robert T. Brandt Jr., S.J. Anderson, J.K. Elliott
Kansas Agricultural Experiment Station Research Reports
Response to monensin (Control, 12.5, or 25 g/ton, air dry basis) by yearling steers fed a diet with 4% added fat was evaluated. For the entire study (104 d), daily gain, feed consumption and feed efficiency were unaffected (P>.25) by monensin. These results are in general agreement with some of our previous reports of diminished animal response to ionophores in fat-supplemented finishing diets. No adverse effects on animal health have been observed in our studies. However, whether withdrawing ionophores from finishing rations with 3.5-4% fat will affect the incidence of digestive upsets in commercial applications is not clear.

Effects Of Speed Of Ration Step-Up And Monensin On Ruminal Ph, Lactate, And Protozoal Population In Feedlot Cattle, G. Towne, Robert T. Brandt Jr., Tiruvoor G. Nagaraja
Kansas Agricultural Experiment Station Research Reports
Fluctuations in ruminal pH, lactate concentration, and ciliated protozoal population were monitored in 40 individually fed crossbred heifers that were stepped up to an 85% concentrate diet either slowly (12 d) or rapidly (3 d), with or without monensin (30 ppm). Speed of step-up affected ruminal pH, lactate concentration and protozoal population initially (up to 28 d), but thereafter no differences occurred between the groups, suggesting adaptation to ruminal conditions. Monensin had no effect on ruminal pH, lactate concentration, or protozoal population.

Effects Of Supplemental Ground Grain Sorghum During Grazing Of Endophyte-Infected Tall Fescue On Grazing And Subsequent Feedlot Performance Of Steers, A.S. Freeman, K.P. Coffey
Kansas Agricultural Experiment Station Research Reports
Sixty-three crossbred steers (740 lb BW) were used to evaluate the effects of energy supplementation during grazing of endoplyte-infected tall fescue and on their subsequent feedlot performance. Grazing ADG was .53 lb/d for control (no supplementation) vs. .81 and 1.21 lb/d with .25% and .5% of BW as ground sorghum (GS), respectively. Grazing supplementation did not affect (P>.10) feedlot performance. Steers receiving .25% GS were 2.3% and 6.2% more efficient (P<.07) during the feedlot phase than 0% and .5% GS steers, respectively. The .5% GS steers were 3.8% less efficient (P<.07) during the feedlot phase than the 0% GS steers. Steers receiving grazing supplementation had increased (P<.07) adjusted backfat measurements and less desirable (P<.02) yield grades than non-supplemental controls. Supplementing steers grazing endophyte-infected fescue at .25% of BW with ground grain sorghum improved feedlot feed conversion compared to no supplementation and supplementing at .5% BW.
Supplementation Of Ammoniated Wheat Straw In Wintering Diets Of Gestating Beef Cows, T.J. Beck, D.D. Simms, Robert T. Brandt Jr., R.C. Cochran, Gerry L. Kuhl
Supplementation Of Ammoniated Wheat Straw In Wintering Diets Of Gestating Beef Cows, T.J. Beck, D.D. Simms, Robert T. Brandt Jr., R.C. Cochran, Gerry L. Kuhl
Kansas Agricultural Experiment Station Research Reports
During two winters, 96 beef cows in late gestation were utilized in 60-day precalving feeding trials to evaluate supplementation for cows fed ammoniated wheat straw. Treatments included: control--mineral supplement only (C), 3 lbs milo + mineral (3M), 6 lb milo + mineral (6M), and 2.75 lb milo + .75 lb soybean meal + mineral (SBM). 3M increased (P<.05) cow gain over control but body condition changes were similar. 6M and SBM resulted in similar gains and body weight changes, which were higher than those of cows receiving either C or 3M. Birth weight of calves, percent cycling at the start of breeding, and percent pregnant after a 60-day breeding season were not affected by treatment. Natural protein appears to be a major limiting nutrient in cows fed ammoniated wheat straw.
Predicting Nutritional Composition Of Corn Grain Using Near Infrared Reflectance Spectroscopy, G. Garcia-Lagombra, L.H. Harbers
Predicting Nutritional Composition Of Corn Grain Using Near Infrared Reflectance Spectroscopy, G. Garcia-Lagombra, L.H. Harbers
Kansas Agricultural Experiment Station Research Reports
Corn grain samples collected over several years were used to develop equations for dry matter, crude protein, crude fiber, and ether extract (crude fat). Two computer models were used to select samples having a range of spectra (presumably a range of nutrient values) for developing calibration equations. Both methods selected an unexpectedly small number of samples; however, only the prediction of crude fiber appears questionable. Although coefficients of determination values are expected to be low with a small number of samples, standard errors of validation and prediction are consistently lower than those of standard (AOAC) methods, suggesting that the technology …
Influence Of Water Treatment On Digestion Dynamics Of Steers Consuming High- And Low-Forage Diets, D.L. Harmon, A.D. Flood
Influence Of Water Treatment On Digestion Dynamics Of Steers Consuming High- And Low-Forage Diets, D.L. Harmon, A.D. Flood
Kansas Agricultural Experiment Station Research Reports
The influence of drinking water treatment (Oxion Inc., Hugoton, KS) on digestion and metabolism was evaluated in steers fed low- and high-forage diets. Water treatment did not influence digestibility of any nutrient measured nor did it influence the profile of ruminal metabolites. Water treatment did increase water consumption two- to threefold and also increased ruminal fractional water outflow (%/h) for steers fed the high forage, but not the high concentrate, diet. Increased water consumption could be a beneficial response, but it is not known if water consumption increases with management programs different than those used in the present study.

Kansas Agricultural Experiment Station Research Reports
Near-infrared reflectance spectroscopy (NIRS) offers the potential for rapid, low-cost analyses of meat samples. Beef and pork samples were analyzed by both standard laboratory (AOAC) methods and NIRS. Regression equations were developed to relate the two methods. Coefficients of determination between NIRS and AOAC results were .929 for dry matter, .965 for crude protein, and .996 for ether extract. NIRS and AOAC procedures yielded very similar results (DM, 38.82 vs 38.58; CP, 17.78 vs. 17.83; and EE, 18.83 vs. 18.00). NIRS appears to be a rapid and reliable predictor of nutritional composition of ground beef and pork based on regression …

The Effect Of Processed Soybeans And Added Energy In Calf Starters On The Growth Of Holstein Calves (1991), P. V. Reddy, J. L. Morrill
Kansas Agricultural Experiment Station Research Reports
In Trial 1, 91 Holstein calves were fed starters containing either soybean meal (SBM), extruded soybeans (ESB), roasted soybeans (RSB), SBM+soy oil (SO), or SBM+rumen inert fat (RIF) from birth to 10 wk of age. There were no differences in overall feed consumption, except that calves fed RSB consumed more than calves fed SBM+SO. There were no significant differences in weight gains, but calves fed SBM+SO tended to gain less. In trial 2, 71 Holstein calves were fed starters containing roasted soybeans from birth to 10 wk of age. Three of the starters contained 18% protein and soybeans roasted at …

One hundred and sixty pigs averaging 127.4 lb were used to determine the benefit of 5% supplemental fat and (or) .20% lysine on growth performance and carcass characteristics. The trial consisted of four treatments: 1) a .61 %, lysine milo-soybean meal control diet; 2) control + 5% fat; 3) control + .20% lysine; 4) control + 5% fat and .20% lysine. Lysine:metabolizable energy ratios were held constant at 1.91: 1 for treatments 1 and 2 and at 2.52: 1 for treatments 3 and 4. Pig weights and feed consumption were recorded every third wk to calculate average daily gain (ADG), …

Two experiments were conducted to evaluate the nutritional value of processed wheat gluten for early-weaned pigs. The first experiment involved 72 weanling pigs with an avg age of 20 d and avg wt of 9.2 lb. Six diets were fed to the pigs in individual metabolism cages. Protein sources were casein, flash-dried wheat gluten, spray-dried wheat gluten, two solubilized wheat glutens, and soybean meal. Response criteria were N digestibility, biological value, and N retention. Casein had greater N digestibility, biological value, and N retention than the other protein sources. The wheat gluten products had greater N digestibility than soybean meal. …

KSU Lean Gain Assessment is a new program developed at Kansas State University to allow producers to assess the actual lean gain of their pigs under normal farm conditions. The procedure is inexpensive and relatively simple and provides information that will assist producers in monitoring their genetic progress. Additionally, farm-specific diets can be formulated to match nutrient levels with the actual genetic potential of pigs on an individual farm.; Swine Day, Manhattan, KS, November 21. 1991
Binding Agents For Low-Salt, Low-Fat, Restructured Beef Roasts: Connective Tissue Or Gelatin, P.B. Kenney, Donald H. Kropf, Curtis L. Kastner
Binding Agents For Low-Salt, Low-Fat, Restructured Beef Roasts: Connective Tissue Or Gelatin, P.B. Kenney, Donald H. Kropf, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
Connective tissue, from the outside of three major chuck muscles, was evaluated for binding properties when incorporated either raw or following preheating into precooked, restructured beef. Food-grade gelatin was also evaluated as a binding agent. Adding 10% raw or preheated connective tissue increased (P<.05) instrumentally measured tensile strength and reduced (P<.05) juiciness perception. One percent gelatin reduced (P<.05) cook yields and increased (P<.05) tensile strength but not to the degree of 10% raw or preheated connective tissue. Preheating had minimal effects on improving connective tissue utility. Based on the improvement in bind and cook yields, use of connective tissue as a binder is feasible in manufacturing low-salt, precooked, restructured beef.

Kansas Steer Futurities: An Economic Analysis Of Retained Ownership And A Summary Of Cattle Performance From 1974-1988, D. Simms, J. Mintert, A. Maddux
Kansas Agricultural Experiment Station Research Reports
The performance, carcass characteristics, and economic data from over 6,200 steers entered in Kansas Steer Futurities from 1974 through 1988 were summarized to evaluate production trends and profitability. The steers' delivery weights, final weights, and frame scores increased over the 14-year period, while daily gain was essentially unchanged. The quality grade, fat thickness, and yield grade all decreased slightly. Ribeye area increased slightly, but ribeye area per unit of carcass remained constant over the years. Based on the delivery weight of the steers, price, normal production relationships, and estimated production costs, we estimate that net returns over cash costs for …

The top 3 feet from 30 horizontal silos was sampled at three depths to determine top spoilage losses, using ash content as an internal marker. When compared to face samples, corn and forage sorghum silages exhibited similar additional organic matter (OM) losses in the top 18 inches. In the top 18 inches, covering silage reduced spoilage losses of OM from 41 to 27 percentage units compared to uncovered counterparts. Covering corn silage reduced spoilage losses of OM from 49 to 31 and 9 to 1 percentage units in the top and second 18 inches, respectively. Similar reductions in OM losses …
