Immunoglobulin Concentrations In Serum And Nasal Secretions Of Calves At The Onset Of Pneumonia (1984), L.B. Corbeil, B. Watt, R.R. Corbeil, T.G. Betzen
Kansas Agricultural Experiment Station Research Reports
Immunoglobulin (Ig) concentrations in serurn and in nasal secretions were correlated with pneumonia and diarrhea during the first 12 wk of life of dairy calves. The peak onset of pneumonia occurred between 2 and 4 wk of age when the calves' serum Ig G1, Ig G2 and IgA concentrations were lowest. As IgG2 concentrations increased, fewer calves developed pneumonia. Peak onset of pneumonia was also correlated with the lowest IgG and IgA concentrations in the calves' nasal secretions. Diarrhea often preceded pneumonia.; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;

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 …
Effects Of Various Feeding, Breeding And Management Practices On Milk Production (1984), James R. Dunham
Effects Of Various Feeding, Breeding And Management Practices On Milk Production (1984), James R. Dunham
Kansas Agricultural Experiment Station Research Reports
The March 1984 DHI summary of Kansas Holstein herds shows some interesting correlations of various feeding, breeding, and management factors to production (Table 1). The Rolling Herd Average (RBA) is an excellent evaluation of the efficiency of dairy herds since RHA and income-over-feed-cost are closely related. Although income-over-feed-cost is not profit, it provides the income for paying the other costs of producing milk. The goal of every dairy producer should be to increase the RHA in order to improve profitability.; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;
Comparison Of Compudose, Ralgro And Synovex-S Implants For Growing Steer Calves, D. Simm, Gerry L. Kuhl, R. Schalles
Comparison Of Compudose, Ralgro And Synovex-S Implants For Growing Steer Calves, D. Simm, Gerry L. Kuhl, R. Schalles
Kansas Agricultural Experiment Station Research Reports
Four field trials were conducted to compare Ralgro, Synovex-S and Compudose implants for growing steer calves. All implant programs significantly increased (P<.01) average daily gain. Reimplanting with Ralgro or Synovex-S improved gain an additional 5.6% compared to the average of these implants used singly and 4.8% compared to Compudose.
Culbac® And Add-F® (Formic Acid) Additives For Sudangrass And High Moisture Shelled Corn Silages, K. Bolsen, M. Hinds, H. Ilg
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.
Effects Of Low Voltage Electrical Stimulation During Bleeding And Hot Boning On Beef Loin Eye And Top Round Muscles, J.B. Axe, Melvin C. Hunt, Donald H. Kropf, D.G. Gray, Curtis L. Kastner, Michael E. Dikeman
Effects Of Low Voltage Electrical Stimulation During Bleeding And Hot Boning On Beef Loin Eye And Top Round Muscles, J.B. Axe, Melvin C. Hunt, Donald H. Kropf, D.G. Gray, Curtis L. Kastner, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Our study evaluated the effects of low voltage electrical stimulation (ES) during bleeding and hot boning at 1 hr postmortem on loin eye (LE) and top round (TR) muscles. Possibly because of relatively slow initial chilling rate used in our study, hot-boned (HB) muscles, even without ES, were comparable to conventionally chilled and boned counterparts. In fact, coupling ES with HB proved less desirable than HB only.
Silo-Best® For Sorghum Silages, K. Bolsen, H. Ilg, M. Hinds
Silo-Best® For Sorghum Silages, K. Bolsen, H. Ilg, M. Hinds
Kansas Agricultural Experiment Station Research Reports
Silo-Best lowered the ensiling temperature and increased the dry matter recovered from the silo by over 5 percentage units (82.3 vs. 77.3%). Calves fed the control silage gained faster and consumed more feed, but those fed treated silage were slightly more efficient. The more efficient gain and lowered shrink loss for Silo-Best silage gave 6.4 extra pounds of calf gain per ton of crop ensiled.
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
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 …
Effect Of Bovatec, Oxytetracycline (Otc), Bovalec Plus Otc And Rumensin-Tylan Combination On Feedlot Performance And Liver Abscess Control In Finishing Steers, B. Lee, S. Laudert
Effect Of Bovatec, Oxytetracycline (Otc), Bovalec Plus Otc And Rumensin-Tylan Combination On Feedlot Performance And Liver Abscess Control In Finishing Steers, B. Lee, S. Laudert
Kansas Agricultural Experiment Station Research Reports
Adding Bovatec, OTC, Bovalec plus OTC or Rumensin-Tylan to finishing steer diets did not significantly improve average daily gain in the 133 day feeding period, but did improve (P<.05) feed to gain ratios. The Rumensin-Tylan combination was the only treatment that reduced (P<.05) liver abscess incidences.

Gonadotropin-Releasing Hormone And Conception Of Holstein Cows (1984), Jeffrey S. Stevenson, M.K. Schmidt, Edward P. Call
Kansas Agricultural Experiment Station Research Reports
To study the effects of gonadotropin-releasing hormone (GnRH) and timing of artificial insemination (Al) on fertility, 328 dairy cows were divided into four groups. Inseminations at first, second, or third service were done soon after detected estrus (0 hr) or 12 h later. One-half of the cows in each of the preceding groups received GnRH (100µg) or saline within 30 sec after AI. Conception at first service was not improved by GnRH. But conception rates at repeat services were improved by 21% when cows received GnRH after AI. Time of AI (0 vs 12 hr) had no effect on conception. …

Effect Of Supplemental Vitamin E On The Performance, Metabolic Profiles, And Immune Responses Of Dairy Calves (1984), P.G. Reddy, J.L. Morrill, H.C. Minocha, M.B. Morrill
Kansas Agricultural Experiment Station Research Reports
Forty-six Holstein heifer calves were used from birth to 3 rno to study the effect of supplemental vitamin E at 1400 or 2800 mg dl-a.-tocopherol acetate given orally at weekly intervals or 1400 mg dl-a-tocopherol by intramuscular injection. Weekly starter consumption was 10 to 27 % more (P=.12) and weekly weight gains were 9 to 25% more (P=.13) in supplemented calves. Creatine phosphokinase activity was negatively correlated with serurn tocopherol concentrations, indicating a subclinical muscular dystrophy in unsupplemented calves. Lymphocyte stimulation indices were positively correlated with serum tocopherol concentration. Calves given high level of oral supplementation had higher IgM antibody …

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 …
Performance And Profitability Of Calves And Yearlings In Southeast Kansas Steer Futurities (Seven Year Summary), C. Lambert, F. Brazle, L. Corah, R. Schalles
Performance And Profitability Of Calves And Yearlings In Southeast Kansas Steer Futurities (Seven Year Summary), C. Lambert, F. Brazle, L. Corah, R. Schalles
Kansas Agricultural Experiment Station Research Reports
Since the fall of 1976, 370 calves and 330 yearlings have been fed through the Southeast Kansas Steer Futurities. In four of the last seven years, both age categories have shown profits through the feedlot phase, using incoming market values assigned by professional market managers, actual feedlot performance and expenses, and slaughter value based on grade and yield date. Calves have been more profitable than yearlings in each of the seven years.
Stocking Rate And Supplementation For Steers Grazing Bluestem Pasture In Early Summer, R. Held, Jack G. Riley, Clenton E. Owensby, E. Smith
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.
Urea And Fermentrol® Additives For Forage Sorghum Silage, B. Janicki, K. Bolsen, M. Hinds, H. Ilg
Urea And Fermentrol® Additives For Forage Sorghum Silage, B. Janicki, K. Bolsen, M. Hinds, H. Ilg
Kansas Agricultural Experiment Station Research Reports
Adding urea to forage sorghum greatly increased the ensiling temperature, produced a more rapid and extensive fermentation, and resulted in more shrink loss in the silo. Fermentrol®, an enzyme-inoculant additive, had very little affect on the silage temperature or chemical composition, but it did reduce the shrink loss. Calves red urea-treated silage had the poorest performance. Control and Fermentrol® silages each produced about 90 lb of calf gain per ton of crop ensiled, however urea silage produced only 60 lb. All three silages had short bunk lives throughout the trial.
Effect Of Ammonia Level And Treatment Temperature On Intake And Digestibility Of Wheat Straw By Lambs, A. Laytimi, K. Bolsen, B. Janicki
Effect Of Ammonia Level And Treatment Temperature On Intake And Digestibility Of Wheat Straw By Lambs, A. Laytimi, K. Bolsen, B. Janicki
Kansas Agricultural Experiment Station Research Reports
Replicate, covered wheat straw (WS) stacks were treated with 1.5 or 3.0% anhydrous ammonia in three environmental chambers at 37, 68, or 95 F, for 23 days. Then digestibility was measured (wethers). Rations were 88% wheat straw and 12% supplement. The control wheat straw was non-ammoniated but contained 5% urea in the supplement. Stack temperatures increased rapidly within 2.5 hours post-ammoniation, and equilibrated at chamber temperatures for the rest of the treatment period. Both crude protein (CP) and in vitro matter digestibility of the WS increased with ammonia level and treatment temperature. Percent of the ammonia recovered increased with temperature …
Comparison Of Synovex-S And Steer-Oid Implants For Feedlot Steers, B. Lee, S. Laudert
Comparison Of Synovex-S And Steer-Oid Implants For Feedlot Steers, B. Lee, S. Laudert
Kansas Agricultural Experiment Station Research Reports
Synovex-S and STEER-oid were compared in a 133-day finishing trial to evaluate their effects on growth and carcass traits of yearling steers. No significant differences in average daily gain, feed intake, feed to gain ratio, carcass weight, ribeye area, fat thickness, quality grade or yield grade were detected between the two implants at the end of the trial. However, significant differences in feed efficiency were detected during days 0-35 and 36-63, possibly due to different release rates of the implants.
Comparison Of Compudose®, Ralgro® And Synovex-C® For Suckling Steer Calves, D.D. Simms, R. Schalles
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.

The Weather In 1982 And 1983, L. Dean Bark
Kansas Agricultural Experiment Station Research Reports
The 1983 weather in Kansas upset carefully laid plans and confounded the best management techniques. Yet the averages for 1982 and 1983 appear very similar. In Manhattan, the average temperatures were 54.04 F for 1982 and 54.06 for 1983. Precipitation totals were 32.88 in. for 1982 and 35.74 in. for 1983. However, those who watched their crops dry up in the summer of 1983 after delayed planting because of wet fields, and suffered with their livestock through heat stress in July and August and cold stress during December know differently. Neither our crops nor our livestock ever experience "average" weather. …

Prostaglandin F2Α For Lactating Dairy Cows With Silent Estrus (1984), S.S. Plunkett, Jeffrey S. Stevenson, Edward P. Call
Kansas Agricultural Experiment Station Research Reports
Two experiments were conducted in 17 dairy herds in NE Kansas to determine the effectiveness of prostaglandin F2α(PGF) for reducing intervals to conception for cows with silent or unobserved estrus. Cows that failed to be seen in heat so they could be inseminated after calving (Exp. 1) and cows that did not return to estrus after AI and were not pregnant when presented to veterinarian for pregnancy examination (Exp. 2) were assigned alternately to be given PGF or to receive no treatment after detection of a palpable corpus luteum. Cows were inseminated at 72 and 96 hr after PGF treatment …
Effect Of Niacin Supplementation On Milk Production And Ketosis Of Dairy Cattle (1984), G. Dufva, E. Bartley, A. Dayton, D. Riddell
Effect Of Niacin Supplementation On Milk Production And Ketosis Of Dairy Cattle (1984), G. Dufva, E. Bartley, A. Dayton, D. Riddell
Kansas Agricultural Experiment Station Research Reports
Two lactation trials were undertaken to evaluate the effect of a niacin supplement on milk production and 'the physiological symptoms of ketosis. Blood ketone and non-esterified fatty acid levels were lower and blood glucose concentrations higher in niacin-supplemented cows. These trends were exhibited regardless of whether supplementation began 2 wk prepartum or immediately after calving. A 6 g daily dose was found to be of equal or higher benefit than a 12 g supplement. Cows gi ven niacin consistently produced more milk than controls, though the difference was small.; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;

Three medication programs for newly purchased feeder calves were compared and found to be similar in effectiveness. There was considerable variation in cost between the three medication programs which indicates a potential cost saving opportunity. Twenty-three percent of the calves received were diagnosed as sick at least once during the 56-day trial.
Silage Additive Update: 1984, K. Bolsen, M. Hinds, J. Brethour
Silage Additive Update: 1984, K. Bolsen, M. Hinds, J. Brethour
Kansas Agricultural Experiment Station Research Reports
Numerous commercial silage additives, whose manufacturers claim will improve silage quality, are available to Kansas farmers and ranchers. We believe that these claims must ultimately be documented with farm-scale research. To date, Manhattan and Ft. Hays farm-scale silo results clearly indicate that a few silage additives do improve silage quality and are cost-effective. Several of them have consistently reduced "in silo" losses. But results probably will not be favorable with all additives under every farm condition. Nor will research results obtained with one commercial product in our trials also apply to other products on the market, however similar in ingredient …

Kansas Agricultural Experiment Station Research Reports
One-hundred and sixty pigs were utilized to evaluate possible interactions between copper (Cu), selenium (Se), and vitamin E (E) on growth and immunity of starter pigs. Copper (260 ppm) added to the diet did not effect Se and/or E utilization for growth, feed efficiency (FE), or immunity. However, addition of 260 ppm of Cu to the diets of starter pigs resulted in an 8% improvement in feed intake (FI) and a 13% improvement in average daily gain (ADG) for the first 2 wk on test. There was no effect on performance due to E additions. However, addition of .3 ppm …

Kansas Agricultural Experiment Station Research Reports
Two feeding trials using 240 finishing pigs were conducted to evaluate meal feeding and ad libitum dry and wet feeding. Growth rate was significantly improved by wet feeding in trial 1. Overall, a 5% improvement in growth rate occurred by wet feeding in both trials when compared with meal-feeding or ad libitum dry feeding. Feed efficiency was similar for pigs fed meals, and ad libitum dry or wet diets.; Swine Day, Manhattan, KS, November 15, 1984
