Feeding Bulls-A Practical Evaluation, D. Simms, L. Corah, Gerry L. Kuhl, R. Schalles Jan 1984

Feeding Bulls-A Practical Evaluation, D. Simms, L. Corah, Gerry L. Kuhl, R. Schalles

Kansas Agricultural Experiment Station Research Reports

Bull calves on nine Kansas ranches were either castrated and implanted with Ralgro, left intact and not implanted, or left intact and implanted with Ralgro, with performance evaluated through slaughter. Bulls produced leaner carcasses and gained slightly faster and more efficiently than steers. However, based on actual prices received, bulls returned $16.09 less to their owners than steers. Implanting with Ralgro during the suckling phase did not influence any of the traits measured. It is evident that marketing is a major problem which makes bull feeding risky

Culbac® And Add-F® (Formic Acid) Additives For Sudangrass And High Moisture Shelled Corn Silages, K. Bolsen, M. Hinds, H. Ilg Jan 1984

Culbac® And Add-F® (Formic Acid) Additives For Sudangrass And High Moisture Shelled Corn Silages, K. Bolsen, M. Hinds, H. Ilg

Kansas Agricultural Experiment Station Research Reports

Laboratory silos were used in three trials to evaluate sudangrass (slightly or moderately wilted) and high moisture corn silages, each receiving the following treatments: (1) control (no additive); (2) CULBAC® dry; (3) CULBAC® liquid; and (4) ADD-F® (formic acid). Although the 12 silages were well preserved visually, there were differences in their chemical compositions. Silages treated with CULBAC dry had the highest DM recoveries and probably the most efficient fermentations. As expected, formic acid restricted the amount of fermentation, but surprisingly, it did not improve DM recovery.

Effect Of A Single Ralgro Implant On Conception Rates And Calving Difficulty In First Calf Beef Heifers, R.P. Bolze, L.R. Corah, R.J. Pruitt Jan 1984

Effect Of A Single Ralgro Implant On Conception Rates And Calving Difficulty In First Calf Beef Heifers, R.P. Bolze, L.R. Corah, R.J. Pruitt

Kansas Agricultural Experiment Station Research Reports

Three hundred and seventy four heifers from two Kansas ranches were used to determine if a single Ralgro implant given either at two months of age or at weaning would influence pelvic development and subsequent calving difficulty or conception rates. The study involved two hers of Simmental (spring and fall calving) and one herd of fall calving Angus cattle. Ralgro did not influence conception rates as yearlings, or percentages of heifers requiring assistance with their first calf. Implanted heifers had larger pelvic areas as yearlings, but the advantage disappeared by two years of age. Pelvic area in assisted vs unassisted …

Bioavailability Of Alfalfa Calcium (1984), L.H. Harbers, G.M. Ward, A.D. Dayton Jan 1984

Bioavailability Of Alfalfa Calcium (1984), L.H. Harbers, G.M. Ward, A.D. Dayton

Kansas Agricultural Experiment Station Research Reports

The availability of oxalate and non-oxalate calcium in alfalfa was determined using a chick assay. Oxalate-bound calcium was found to contribute only 16% as much influence as nonoxalate calcium. The nonoxalate calcium in alfalfa was 18% more available than calcium carbonate (precipitated chalk).; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;

Effects Of Compudose® Implants On Performance Carcass, Meat Quality Traits And Serum Testosterone In Young Boars (1984), T Timmis, Michael E. Dikeman, Melvin C. Hunt, G Highfill, Jeffrey S. Stevenson, Robert H. Hines Jan 1984

Effects Of Compudose® Implants On Performance Carcass, Meat Quality Traits And Serum Testosterone In Young Boars (1984), T Timmis, Michael E. Dikeman, Melvin C. Hunt, G Highfill, Jeffrey S. Stevenson, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Implanting boar pigs at 100 lb with 24 mg of Compudose 200® (estradiol 17β) had no significant effect on "boar odor" in meat, rate of gain, feed efficiency, carcass leanness or meat quality traits. The presence of a 7 to 8 mo old gilt in the pen decreased rate of growth in both control and implanted boars, but contrary to our expectations did not increase the incidence of "boar odor".; Swine Day, Manhattan, KS, November 15, 1984

Efficacy Of Ectrin® (Fenvalerate) For Sarcoptic Mange Control In Swine (1984), E L. Wooten, A B. Broce, D S. Pollmann Jan 1984

Efficacy Of Ectrin® (Fenvalerate) For Sarcoptic Mange Control In Swine (1984), E L. Wooten, A B. Broce, D S. Pollmann

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to determine the efficacy of fenvalerate (Ectrin®) for control of sarcoptic mange mites in swine. Artificially infested pigs were treated with two sprayings of Ectrin at 0.05% concentration with 1 wk interval between sprayings. One week after the first spraying, mite numbers and clinical signs of mange had decreased in treated animals but remained elevated in infested-nontreated pigs. Four weeks after the first spraying (3 wk after the second spraying), no mites were found in scrapings from the Ectrin-treated pigs and the amount of scratching and rubbing in those pigs decreased compared with the infested- nontreated …

Time-Restricted Feeding Of Pigs: Social And Feeding Behavior (1984), J Vargas Vargas, J V. Craig, Robert H. Hines Jan 1984

Time-Restricted Feeding Of Pigs: Social And Feeding Behavior (1984), J Vargas Vargas, J V. Craig, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Twenty finishing pigs were used to evaluate effects of time-restricted feeding on social interactions and feeding patterns of pigs at feeding time. Correlation analysis for pairs of traits, involving feeding activities, social interactions, and rate of gain indicate that more aggressive pigs went first to the feeder, fed more frequently, and gained faster. Although on continuous artificial lighting, timed-fed pigs displayed more feeding and aggressive behavior during day light hours.; Swine Day, Manhattan, KS, November 15, 1984

Silo Guard Ii® For Alfalfa, Corn, And Forage Sorghum Silages, K. Bolsen, H. Ilg, M. Hinds Jan 1984

Silo Guard Ii® For Alfalfa, Corn, And Forage Sorghum Silages, K. Bolsen, H. Ilg, M. Hinds

Kansas Agricultural Experiment Station Research Reports

In the first trial, calves fed Silo Guard II®-treated forage sorghum silage were 4.2% more efficient than those fed the control silage. Silo Guard II reduced the amount of heat produced during the ensiling process, and increased the dry matter recovered from the silo by nearly 7 percentage units (84.1 vs. 77.2%). The more efficient gain and reduced shrink loss for the treated silage gave 8.3% extra pounds of calf gain per ton of crop ensiled when compared with the control silage. In the second trial, laboratory silos were used to evaluate three levels of Silo Guard II (.5, 1.0, …

Effects Of Low Voltage Electrical Stimulation During Bleeding On Characteristics Of Beef Loin Eye Top Round Muscles, Donald H. Kropf, Melvin C. Hunt, John A. Unruh, Curtis L. Kastner, Michael E. Dikeman Jan 1984

Effects Of Low Voltage Electrical Stimulation During Bleeding On Characteristics Of Beef Loin Eye Top Round Muscles, Donald H. Kropf, Melvin C. Hunt, John A. Unruh, Curtis L. Kastner, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Low voltage electrical stimulation (ES) during bleeding and subsequent carcass chilling at 36 to 46° F resulted in 1) a more rapid pH decline 2) initial lighter red color, but more rapid discoloration during display 3) softer and coarser textured lean 4) reduced water holding capacity and juiciness and 5) decreased tenderness of the loin eye longissimus (LE) muscle when compared to the non-stimulated control (C) LE muscle. ES effects on top round semimembranosus (TR) muscle were limited to a more rapid pH decline and lower water holding capacity. Our results indicate that ES soon after slaughter, coupled with relatively …

Stocking Rate And Supplementation For Steers Grazing Bluestem Pasture In Early Summer, R. Held, Jack G. Riley, Clenton E. Owensby, E. Smith Jan 1984

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

Kansas Agricultural Experiment Station Research Reports

Native bluestem pastures were grazed from May 16 to July 14, 1983 by steers with an average beginning weight of 545lbs., at stocking rates of 1.82, 1.5, and 1.25 acres per steer. Daily gains for the high and low stocking rates were higher (P<.01) than for the medium stocking rate (2.22, 2.24 vs. 1.92 lb/day). Gains per acre were similar for the low and medium stocking rates, but was higher for the highest stocking rate (73, 75 vs 105 lb/acre). Half of the steers in each stocking rate were self-fed a salt-limiting sorghum grain- Rumensin® mixture at an average intake of 1.84 lb per head per day. Supplementation increased daily gain (P<.01) over non-supplemented (2.39 vs. 1.86 lb/day). Gain per acre was increased 22 lbs by supplementation. Herbage remaining following grazing decline with increased stocking rate. No regrowth occurred following livestock removal in mid July. Warm-season perennial grass composition and basal cover have not changed differentially in relation to stocking rate during the 3-year study period.

Implant Comparisons For Finishing Steers, S. Laudert, Gerry L. Kuhl, M. Walker Jan 1984

Implant Comparisons For Finishing Steers, S. Laudert, Gerry L. Kuhl, M. Walker

Kansas Agricultural Experiment Station Research Reports

A one hundred and forty day field trial was conducted to evaluate the relative performance of steers implanted with Compudose, Ralgro and Synovex-S. Daily gains of cattle receiving a single initial implant were increased 8.0% with Compudose, 12.7% with Ralgro and 21.5% with Synovex-S compared to non-implanted controls. Steers on a reimplant program with Ralgro and/or Synovex-S gained 23.6 to 24.9% faster than controls, with no significant difference due to implant brand or sequence.

Comparison Of Compudose®, Ralgro® And Synovex-C® For Suckling Steer Calves, D.D. Simms, R. Schalles Jan 1984

Comparison Of Compudose®, Ralgro® And Synovex-C® For Suckling Steer Calves, D.D. Simms, R. Schalles

Kansas Agricultural Experiment Station Research Reports

The comparative growth-promoting value of Compudose, Ralgro, Ralgro + Ralgro reimplant, and Synovex-C + Synovex-C reimplant was evaluated on five Kansas ranches with 674 suckling steer calves in seven trials conducted during 1982 and 1983. The Ralgro + Ralgro reimplant program increased gain significantly (P<.05) over controls, with an average improvement of 3.9%. Either a single Ralgro or Compudose implant at branding increased gain about 2.6%. Implanting with Synovex-C produced 1% improvement in gain.

Effect Of Processing Temperature On Utilization Of Whole Soybeans By Young Calves (1984), I.E.O. Abdelgadir, J.L. Morrill, J.A. Stutts, B. Morrill Jan 1984

Effect Of Processing Temperature On Utilization Of Whole Soybeans By Young Calves (1984), I.E.O. Abdelgadir, J.L. Morrill, J.A. Stutts, B. Morrill

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to determine the optimum conditions for processing whole soybeans for young calves. In the first trial, laboratory procedures and a nitrogen balance study were used. This information was used to design the second trial in which raw and processed soybeans were evaluated in an 8-wk growth trial using 96 Holstein day-old calves. Starters contained soybean meal (SBM), SBM with added fat, raw soybeans, or soybeans processed at 280, 340, or 375°F in a California Pellet Mill Jet-Sploder. Calves fed the starters containing soybeans processed at 340 consumed more feed, gained faster, had lower fecal scores (less …

Evaluation Of Raw And Processed Full-Fat Soybeans For High-Producing Dairy Cows (1984), G.M. Ward, J.L. Morrill, M.B. Morrill, A.D. Dayton

Kansas Agricultural Experiment Station Research Reports

Rations containing either soybean meal, raw full-fat soybeans, or processed soybeans were compared using 36 high-producing dairy cows in early lactation. The processed soybeans were heated in a California Pellet Milt Jet-Sploder for sufficient time (about 1 min) to produce beans with exit temperature of 340°F. The raw soybeans and heated soybeans were rolled before being"¢ mixed into the concentrate mixture. Alfalfa hay and concentrate were consumed ad libitum in a ratio of 35 % hay and 65 % concentrate. Milk production and percent protein in milk were significantly greater when cows were fed soybean meal or Jet-Sploded beans than …
