Effect Of Energy Intake On Semen Characteristics, Sex Drive, And Scrotal Circumference Of Yearling Beef Bulls, D. Pruitt, L. Corah, G. Kiracofe, M. Mckee, M. Spire Jan 1983

Effect Of Energy Intake On Semen Characteristics, Sex Drive, And Scrotal Circumference Of Yearling Beef Bulls, D. Pruitt, L. Corah, G. Kiracofe, M. Mckee, M. Spire

Kansas Agricultural Experiment Station Research Reports

Simmental and Hereford bulls were fed individually three levels of energy per breed for 200 days beginning shortly after weaning. Then all bulls were adjusted to a roughage ration for 10 days, before grazing brome pasture for 38 days as one group. High energy did not decrease semen quality or sex drive. Energy level affected scrotal circumference of the Simmentals but not Herefords. Weight loss on pasture did not decrease semen quality or sex drive.

Comparison Of Cattle Types And Management Systems, R.R. Schalles, K. Bolsen, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

No differences were found in total feed energy required to produce a pound of retail cuts between breeds or management systems. However, across breeds, faster gaining steers were more efficient. When yardage, facilities, labor and interest were also considered, faster gaining cattle and accelerated management programs were more economical.

Effect Of Reimplanting With Ralgro On Performance And Carcass Characteristics Of Feedlot Heifers, D. Simms, Gerry L. Kuhl, S. Tonn, R. Schalles

Kansas Agricultural Experiment Station Research Reports

A field study was conducted to evaluate the effect of reimplanting, and of implanting technique, on the performance of yearling heifers. Daily gains of reimplanted, single implanted and non-implanted cattle averaged 3.00, 2.93 and 2.81 lb, respectively. Implanting Ralgro at the base of the ear produced a slight and not statically significant increase in again over the "old" site 1 to 2 in. from the base of the ear. Feed efficiency of the single implant heifers was 5.5% better than controls, with an additional 1.9% improvement due to reimplanting. Carcass characteristics were not materially influenced ...


Heat Synchronization With Alfaprostol, L.E. Keay, G. Kiracofe, Kenneth G. Odde, Jeffrey S. Stevenson Jan 1983

Heat Synchronization With Alfaprostol, L.E. Keay, G. Kiracofe, Kenneth G. Odde, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

One-hundred eighteen heifers were used to determine the effectiveness of Alfaprostol as a heat synchronization agent. Seventy-nine were injected twice (12 days apart) with 6 mg Alfaprostol per head and 39 were not treated. Twelve to 96 hours after the second injection 88.6% of the treated heifers were in standing heat and 81.4% of those in heat conceived at the first insemination. Eighty-one percent of the 37 untreated heifers in heat the first 21 days conceived at the first insemination. Ninety-one percent of the treated heifers and 89.2% of the untreated heifers conceived within a 50-day breeding ...


Comparative Intake Of Bone Meal And Calcium Phosphate Mineral Mixtures As Phosphorus Sources For Grazing Steers And Lactating Cows, F. Brazle, Gerry L. Kuhl, T. Wary, Dale L. Lanham Jan 1983

Comparative Intake Of Bone Meal And Calcium Phosphate Mineral Mixtures As Phosphorus Sources For Grazing Steers And Lactating Cows, F. Brazle, Gerry L. Kuhl, T. Wary, Dale L. Lanham

Kansas Agricultural Experiment Station Research Reports

Steers on native grass consumed equal amounts of mixtures containing 50% trace mineralized salt and either 50% bone meal or 50% calcium phosphate. Lactating cows consumed about 60% more of the bone meal:salt mixture. This research verifies that both products are palatable supplemental phosphorus sources and that choice of product should be a function of cost per unit of phosphorus.


Aborting Feedlot Heifers With Alfaprostol, L.E. Keay, G. Kiracofe, M. Simon, Jack G. Riley Jan 1983

Aborting Feedlot Heifers With Alfaprostol, L.E. Keay, G. Kiracofe, M. Simon, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

The effectiveness of alfaprostol in inducing abortion was tested in 93 pregnant heifers. Alfaprostol was injected intramuscularly, .7 mg per 100 pounds body weight. Twenty-four heifers were injected when they averaged 83 days (range 64 to 86) pregnant, while 23 were injected when 138 days (range 119-143) pregnant. A control injection of the Alfaprostol carrier, propylene glycol, was given 23 heifers averaging 81 or 134 days pregnant. By 14 days after the Alfaprostol injection 79% of the heifers 83 days pregnant and 96% of the heifers 138 days pregnant had aborted. Two of the 83-day controls and none of the ...


Efficacy Of Lutalyse® As An Abortifacient In Feedlot Heifers, D. Simms, Gerry L. Kuhl, S. Tonn, R. Schalles Jan 1983

Efficacy Of Lutalyse® As An Abortifacient In Feedlot Heifers, D. Simms, Gerry L. Kuhl, S. Tonn, R. Schalles

Kansas Agricultural Experiment Station Research Reports

Lutalyse aborted 86.7% of heifers 40 to 100 days pregnant. Of four heifers tested at 101 to 150 days pregnant, all aborted. Open heifers gained faster (P<.05) than heifers that either were aborted or pregnant at slaughter. Those pregnant at slaughter had lower (P<.05) dressing percentages than either open or aborted heifers.


Inoculant And Urea-Molasses Additives For Forage Sorghum Silage, M. Hinds, J. Brethour, K. Bolsen Jan 1983

Inoculant And Urea-Molasses Additives For Forage Sorghum Silage, M. Hinds, J. Brethour, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Inoculant (1177 in one trial) and non-protein nitrogen (LSA-100 in two trials) silage additives were evaluated with whole-plant forage sorghum silage. Steers fed LSA-100 silage gained faster than steers fed control silage supplemented with soybean meal (4.8% in trial 1; 12% in trial 2). Feed conversion was improved 11% in trial 1 and was similar to the control silage in trial 2. Silage inoculated with 1177 supported rates and efficiencies of gain similar to the control silage. Of the nitrogen added from LSA-100, 90.9% in trial 1 and 86.2% in trial 2 was recovered from the concrete ...

Effect Of Reimplanting Feedlot Heifers With Ralgro® And/Or Synovex-H®, D. Latourell, Gerry L. Kuhl, C. Drake

Kansas Agricultural Experiment Station Research Reports

Implanting heifers initially and mid-way through the finishing period with Ralgro and Synovex-H in any combination produced similar weight gains. Daily gains of cattle implanted with Ralgro + Ralgro, Ralgro + Synovex-H, Synovex-H + Ralgro and Synovex-H + Synovex-H were 3.66, 3.61, 3.66 and 3.75 lbs, respectively.


Effect Of Lasalocid Or Monensin On Feedlot (Grain) Bloat In Cattle, E.E. Bartley, Tiruvoor G. Nagaraja Jan 1983

Effect Of Lasalocid Or Monensin On Feedlot (Grain) Bloat In Cattle, E.E. Bartley, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Lasalocid or monensin (600 mg per 1000 lb body weight daily) was tested on cattle bloating on high grain diets. Bloat was reduced 92% by Lasalocid and 64% by monensin. When fed throughout the finishing period, lasalocid at 300 mg per 1000 lb body weight effectively prevented bloat from developing. However, 600 mg was required to control bloat in cattle that were already bloating.


A Summary Of Recent Kansas State University Research On The Metabolism Of Supplemental Niacin In The Rumen Of Cattle, E.E. Bartley, D.O. Riddell, M.A. Arambel, S.M. Dennis Jan 1983

Response Time To Estrus Synchronization, R.R. Schalles, M. Spire, C. Clarke

Kansas Agricultural Experiment Station Research Reports

Heavy milking cows took longer to respond to estrus synchronization than light milking cows. There was no difference in response time between cows treated with Estrumate and Lutalyse. Cow weight, height or condition had no effect on estrus response time.


Whole-Plant Forage, Grain Or Non-Heading Sorghum Silages, Cornlage, And Feed Flavor Supplements For Growing Calves, K. Bolsen, H. Ilg, M. Hinds, J. Hoover, Ronald V. Pope Jan 1983

Whole-Plant Forage, Grain Or Non-Heading Sorghum Silages, Cornlage, And Feed Flavor Supplements For Growing Calves, K. Bolsen, H. Ilg, M. Hinds, J. Hoover, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Four whole-plant silages produced in 1981 and 1982 were evaluated using 176 calves in two growing trials. Based on comparative rates and efficiencies of gain, feeding values were 115, 100, 78.5, and 62 for the cornlage, grain sorghum, forage sorghum, and non-heading sorghum silages, respectively. The poorer values for the forage and non-heading silages were due, in part, to low feed intakes. Rolling the grain and forage sorghum silages to break 85% to 95% of the kernels did not improve their value, and the good performance by calves suggests that the whole grain was well utilized.. A feed flavor ...


Cause And Effect Of Calving Difficulty In First Calf Heifers On Subsequent Reproductive Performance And Weaning Weights Of Progeny, R.P. Bolze, R.J. Pruitt, L.R. Corah Jan 1983

Cause And Effect Of Calving Difficulty In First Calf Heifers On Subsequent Reproductive Performance And Weaning Weights Of Progeny, R.P. Bolze, R.J. Pruitt, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Eight years of records for 1495 2-year old beef heifer calvings from two Kansas ranches were analyzed to determine the cause and effect"¢ of calving difficulty on subsequent reproductive performance and weaning weights of progeny. The study involved two herds of Simmental cattle (spring and fall calving) and one herd of fall calving Angus cattle. Heifers were classified as either requiring or not requiring assistance with their first calf. Herds were analyzed separately. Percentages of heifers requiring assistance for the Angus, spring calving Simmental and fall calving Simmental herds were 36%, 57% and 38%, respectively. In all herds, calves from ...


Additive-Treated Corn Silage, Harvestore Cornlage, And Sodium Bicarbonate Supplement For Yearling Steers, S. Soderlund, K. Bolsen, H. Ilg, J. Hoover Jan 1983

Additive-Treated Corn Silage, Harvestore Cornlage, And Sodium Bicarbonate Supplement For Yearling Steers, S. Soderlund, K. Bolsen, H. Ilg, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Steers fed Silo Guard II® treated corn silage gained 3.5% faster and were 8.3% more efficient than those fed the control silage. Cornlage (54% dry matter corn silage in an oxygen-limiting structure) produced numerically slower and less efficient gains than either treated or untreated silage, but differences in silages were not statistically significant. Steers fed sodium bicarbonate throughout the trial consumed 8.5% more silage, gained 14% faster (P<.05), and were 3% more efficient than those not fed bicarbonate; performance of steer fed bicarbonate for the first half of the trial was intermediate. Steers fed cornlage had a higher rumen fluid acetate:propionate ratio (P<.05) than those fed the control or Silo Guard II silages but there were no significant differences due to bicarbonate in rumen fluid volatile fatty acids. Silage DM recoveries and aerobic stabilities were similar for the control and Silo Guard II silages. Cornlage was less stable in air than the other two silages.


High-Moisture Or Dry Corn, Roughage Sources, And Protein Supplements For Short-Fed Finishing Steers, B. Young, H. Ilg, K. Bolsen Jan 1983

High-Moisture Or Dry Corn, Roughage Sources, And Protein Supplements For Short-Fed Finishing Steers, B. Young, H. Ilg, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Dry corn, stave ensiled high-moisture corn (HMC), stave ensiled HMC treated with urea, and Harvestore ensiled HMC were evaluated in a steer finishing trial. Alfalfa hay and corn silage were the roughages and soybean meal or urea, the nitrogen sources. There were no differences in steer performance for corn treatments, but steer performance was significantly improved when alfalfa hay rather than corn silage was the roughage. Urea supplements significantly depressed steer performance compared with soybean meal additions; a combination of urea and soybean meal gave intermediate performance.


Elpwa And Molasses Additives For High Moisture Sorghum Grain, J. Heidker, H. Ilg, K. Bolsen, Keith C. Behnke Jan 1983

Elpwa And Molasses Additives For High Moisture Sorghum Grain, J. Heidker, H. Ilg, K. Bolsen, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

ELPWA (a lactobacillus inoculant with antioxidant), molasses, or both combined were evaluated as additives to high moisture sorghum grain ensiled in concrete stave silos. ELPWA treated grain had the greatest temperature increase during ensiling. Final lactobacillus counts were higher in the ELPWA + molasses treated grain, however, the initial rate of increase was greatest in ELPWA or molasses treated grains. Control and molasses treated grains had the fastest decline in pH and the lowest final pH. Aerobic stability of the ensiled grain depended on the strata of the silo sampled and the temperature to which the grain was exposed but aerobically ...


Eating And Cooking Loss Characteristics Of Electrically Stimulated And Hot Boned Bull Inside Round Muscle Chilled At Different Rates, S.D. Shivas, Curtis L. Kastner, Michael E. Dikeman, Melvin C. Hunt, Donald H. Kropf Jan 1983

Eating And Cooking Loss Characteristics Of Electrically Stimulated And Hot Boned Bull Inside Round Muscle Chilled At Different Rates, S.D. Shivas, Curtis L. Kastner, Michael E. Dikeman, Melvin C. Hunt, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

We found steaks cut from inside rounds (chilled fast or slow) of electrically stimulated and hot boned bull carcasses, to be similar to conventionally processed steaks in taste panel, shear force and cooking loss characteristics.


Steer Gains On Burned And Nonburned Bluestem Pasture, 1978 To 1982, E.F. Smith, Clenton E. Owensby Jan 1983

Steer Gains On Burned And Nonburned Bluestem Pasture, 1978 To 1982, E.F. Smith, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

From 1978 to 1982, steers on a late spring burned pasture averaged 40 lbs more gain each summer than steers on a non-burned pasture.


Effects Of Electrical Stimulation And Hot Boning On The Functional Characteristics Of Presalted Beef Muscle Used In Sausage Manufacturing, Y.I. Choi, Melvin C. Hunt, Donald H. Kropf, Curtis L. Kastner, Michael E. Dikeman Jan 1983

Effects Of Electrical Stimulation And Hot Boning On The Functional Characteristics Of Presalted Beef Muscle Used In Sausage Manufacturing, Y.I. Choi, Melvin C. Hunt, Donald H. Kropf, Curtis L. Kastner, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Presalted, hot-boned muscle has excellent emulsifying properties for sausage manufacturing. However, electrical stimulation degrades these properties. Thus, while electrical stimulation and hot boning produce acceptable steaks and roasts, the value of the trimmings used in manufactured meat products may be lowered. Presalting maintained the high pH values of the hot-boned muscle during 24 hours storage.


Stocking Rate, Supplementation And Implants For Steers Grazing Bluestem Pasture In Early Summer, R. Held, E.F. Smith, Jack G. Riley, Clenton E. Owensby Jan 1983

Stocking Rate, Supplementation And Implants For Steers Grazing Bluestem Pasture In Early Summer, R. Held, E.F. Smith, Jack G. Riley, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Native bluestem pastures were grazed from May 10 to July 15, 1982 by steers averaging 599 lbs, at stocking rates 1.82, 1.5, 1.2 acres per steer. Daily gains were similar for all rates, but gain per acre increased with increased stocking rate. Half of the steers were self-fed a salt-limiting sorghum grain-Rumensin® mixture, at about 1.8lb per steer per day. Supplementation increased daily gain (P<.05) but actual differences were small (2.08 vs. 1.91 lb per day). Gain per acre was increased 7 lbs by supplementation. Herbage yields at mid-July were least on the heavily stocked pastures, but by October regrowth on all pasture was equal. Stocking rate did not affect botanical composition. There were no significant gain differences for steers implanted with either Compudose®, Ralgro® or Synovex®, even though 24 percent of the Compudose implants were lost by mid-summer.


Ascorbic Acid And Ground Beef Display Life, S.D. Shivas, Donald H. Kropf, Melvin C. Hunt, J.L.A. Kendell, A.D. Dayton, Curtis L. Kastner Jan 1983

Ascorbic Acid And Ground Beef Display Life, S.D. Shivas, Donald H. Kropf, Melvin C. Hunt, J.L.A. Kendell, A.D. Dayton, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Adding .05 and .10% ascorbic acid to ground beef resulted in brighter color and longer display life, more intense taste panel beef flavor and less rancidity. Those advantages should encourage centralized retail cutting and packaging by reducing spoilage and loss. Ground beef with 25% fat had brighter color scores and lower microbial counts but was more off-flavor than 20% fat ground beef.


Lighting Effects On Beef Carcass Grade Factors, Donald H. Kropf, Melvin C. Hunt, H.R. Cross, Michael E. Dikeman Jan 1983

Lighting Effects On Beef Carcass Grade Factors, Donald H. Kropf, Melvin C. Hunt, H.R. Cross, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Beef carcass quality factors were evaluated under 25 different lighting systems (five lighting types each at five light intensities). Cool White fluorescent caused the darkest and most mature lean score, but marbling quantity score was not affected by lighting type or intensity. Lean was scored progressively brighter and more youth with increasing lighting intensity.
