Item Open Access Level of Vitamin A in beef steer finishing ration fed on high and low levels of silage(Kansas Agricultural Experiment Station, 2011-04-28) Richardson, D.; Smith, E.F.; Harbers, L.H.; Buamah, T.F.Sixty Hereford steer calves from Warner’s Ranch in Rice County were wintered on a ration of 1 pound soybean oil meal, sorghum silage, sorghum rain and minerals. The calve weight 450 to 550 pounds; 30 were fed 4 pounds of grain and 30 were fed 8 pounds of grain per head daily for 112 days. They average approximately 743 pounds at the end of the wintering period.Item Open Access Influence of breeding and length of feeding period on carcass characteristics and palatability of beef(Kansas Agricultural Experiment Station, 2011-04-28) Mackintosh, D.L.; Kropf, Donald H.; Flectcher, R.C.; Ahlschwede, G.A.During 1962-63, in cooperation with the American Hereford Association, 76 head of Hereford steers, sired by four different bulls, were slaughtered in Kansas City and the rib cut from 40 (10 from each sire group) was purchased for detailed analyses and palatability tests, a procedure following with all cattle on this phase of the project.Item Open Access Influence of nitrogen source on ruminal pH, ammonia production and protein synthesis(Kansas Agricultural Experiment Station, 2011-04-28) Harbers, L.H.; Richardson, D.; Abe, R.K.Previous reports from this station indicate little advantage in feeding combined sources of protein (soybean meal and cottonseed meal) to beef cattle. The results were obtained by determining total nitrogen and protein nitrogen in the rumen of fistulated steers at six hours after feeding. By this technique, data that express the ability of the microorganisms to convert nitrogen to bacterial protein may be rapidly determined. Bacterial protein has high biological value; it is, thus, important that maximum conversion be obtained from nitrogen sources of less biological value. Factors that influence conversion can be carefully controlled using fistulated animals. Once optimum rations are formulated under such conditions of rapid screening , costly feeding trials can be minimized.Item Open Access Nutritive value of forages as affected by soil and climatic differences(Kansas Agricultural Experiment Station, 2011-04-28) Richardson, D.; Banbury, Evans E.; Elliott, H.; Erhart, A.B.; Williams, G.; Russ, Oliver G.; Smith, E.F.; Harbers, L.H.; Adepoju, A.; Cox, R.F.This is a progress report on the third test to determine whether there is a difference in the performance of beef steers due to location, soil, climate, rainfall and/or feed produced in farm areas of Kansas: Colby, Garden City, Manhattan, and Mound Valley. Forty-eight Hereford steer calves averaging 475 pounds and from the same herd as steers used in the second test were divided into four groups of 12 animals. One lots was assigned to each of the four locations. The test is being conducted in the same manner as the two previous tests except that concrete has replaced soil floors under the sheds.Item Open Access Nutritive value of forages as affected by soil and climatic differences(Kansas Agricultural Experiment Station, 2011-04-28) Richardson, D.; Banbury, Evans E.; Erhart, A.B.; Williams, G.; Russ, Oliver G.; Smith, K.F.; Loper, D.C.; Harbers, L.H.; Cox, R.F.This is the second test to measure differences, if any, in performance of cattle in various parts of Kansas due to location, soil, climate, rainfall and/or local feed. Forty-eight Hereford steer calves from the same herd averaging 454 pounds each were divided as uniformity as possible into four groups of 12 animals. One group was assigned to each of the four locations: Colby, Garden City, Manhattan and Mound Valley.Item Open Access The effects of silage additives on the feeding value of forage sorghum silage(Kansas Agricultural Experiment Station, 2011-04-28) Ward, G.M.; Smith, E.F.; Richardson, D.; Boren, Fred W.This experiment was to determine effects from adding glucose, sucrose and starch to forage sorghum (DeKalb FSla) immediately prior to ensiling, on the feeding value of the subsequent silage. When the forage sorghum grain was at medium-to-hard dough stage, it was field chopped with a conventional silage cutter. Dry matter the forage was determined at harvesting and equalized by adding water. Each additive was added to the forage prior to ensiling. The sorghum forage was ensiled in 40-ton concrete stave silos.Item Open Access Cane molasses and hemicelluloses extract (wood molasses) in rations for finishing steers. The value of shelter for finishing cattle(Kansas Agricultural Experiment Station, 2011-04-28) Pfost, H.B.; Smith, E.F.; Richardson, D.; Boren, Fred W.the only variable planned in the diet was type of molasses, which composed 16% of the self-fed roughage-concentrate mixture. Cane molasses was used in two lots; hemicelluloses extract in two lots. The self-fed roughage-concentrate mixture was composed of these ingredients: soybean oil meal, 10%; rolled sorghum grain, 40%; ground rice hulls, 35%; molasses, 10%l urea, dicalcium phosphate and premix, 1% each. The premix supplied 10 mgs. Stillbesterol, 70 mgs. Aureomycin and 28,000 I.U. Vitamin A per steer daily.Item Open Access Feed additives in pig starter rations(Kansas Agricultural Experiment Station, 2011-04-28) Jensen, A.H.; Koch, B.A.; Harbers, L.H.; Miller, L.A.Three experiments were conducted to determine the efficacy of certain feed additives, alone or in various combinations, in improving performance of pigs weaned at 4 weeks of age. In the first two, each treatment group of pigs was confined to a 3 ½ by 8-foot concrete-floored pen in the central farrowing unit. In the third experiment 3-by6-foot pens with either flattened expanded metal or wood slat floors were used. A 25-watt light was suspended above the sleeping area in each pen to provide supplementary heat. Wood shavings were used for bedding in the first two experiments, but no bedding was used in the third experiment.Item Open Access Comparison of feed additives in rations for growing-finishing swine(Kansas Agricultural Experiment Station, 2011-04-28) Koch, B.A.; Loeppke, D.W.Seventy-two pigs were used. They averaged about 50 pounds each at the start of the experiment. During the first 28 days the pigs that received a diet containing Aureo S.P.-250 (100 gms. Chlortetracycline, 100 gms. Sulfamethazine and 50 gms. Penicillin per ton of feed) gained about 13% faster than pigs on diets containing either chloreteracycline or tylosin at 10 gms. Per ton of feedItem Open Access Improvement of beef cattle through breeding(Kansas Agricultural Experiment Station, 2011-04-28) Smith, W.H.; Wheat, J.D.; Spies, H.G.The purebred Shorthorn cattle breeding program was continued during 1964 according to the plan initiated in 1949. Inbreeding of the two lines has been continued. The Wernuere Premier Line is in its fifth generation and the Mercury line in its fourth generation of inbreeding. The inbreeding program for both lines has been basically to continue successive generations of half-sibbing.Item Open Access Flavoring compounds and wood molasses in growing-finishing rations(Kansas Agricultural Experiment Station, 2011-04-28) Koch, B.A.; Loeppke, D.W.Two flavoring compounds, monosodium glutamate (MSG) and flance, were used separately and in combination in rations for growing-finishing swine. Wood molasses, a source of energy, was used with the two flavoring compounds. Sixty –three pigs were used. Each pen of 9 pigs was confined to a concrete-floored pen in building M. Feed and water were available at all times. All rations were pelleted, with the test ingredients replacing sorghum grain in the formulation.Item Open Access The value of feed lot lighting(Kansas Agricultural Experiment Station, 2011-04-28) Lipper, R.; Smith, E.F.; Richardson, D.; Boren, Fred W.In the two tests reported here the concentrate mixture or roughage-concentrate mixture was before the animals at all times. In addition a small amount of prairie hay was fed. In Lots 6 and 3 yearling Hereford feeder heifers was used, in Lots 17 and 13, yearling Hereford steers were the experimental animals. All the animals graded good to choice as feeders.Item Open Access Level of protein for heifer calve wintered on bluestem pasture(Kansas Agricultural Experiment Station, 2011-04-28) DeGeer, C.V.; Smith, E.F.; Richardson, D.; Good, D.L.The 66 heifers used were good-to-choice Herefords purchased near Fort Davis, Texas, assigned to treatments on a random weight basis. The heifers were rotated between pastures to minimize any difference due to pastures during the first winter grazing period and the summer grazing period. Dicalcium phosphate was fed to standardize phosphorus intake between groups during the first winter grazing period.Item Open Access A comparison of different methods of getting cattle on a high grain ration and the value of prairie hay in finishing rations(Kansas Agricultural Experiment Station, 2011-04-28) Clark, M.C.; Smith, E.F.; Richardson, D.; Dunn, L.; Boren, Fred W.Cottonseed hulls have been used extensively in cattle rations as a source of roughage; the content in the ration is usually gradually lowered until the desired amount of concentrate is being consumed. In this study wheat bran was compared with cottonseed hulls for roughage. Since the question whether either feed was necessary arose, a third treatment was added where the heifers were turned directly on the self-feeder, in addition to the concentrate mixture in the self-feeder.Item Open Access Supplementing prairie hay rations with urea and trace minerals(Kansas Agricultural Experiment Station, 2011-04-28) Smith, K.F.; Richardson, D.; Loeppke, D.W.; Boren, Fred W.The trace minerals, cobalt, iodine, copper, and zinc, were added to a prairie hay-limited sorghum grain ration in an effort to improve utilization of prairie hay. Since increased quantities of urea are being successfully used in high-energy rations, its value as a protein extender in a primarily prairie hay ration was tested.Item Open Access Different methods of managing bluestem pasture(Kansas Agricultural Experiment Station, 2011-04-28) Smith, E.F.; Anderson, K.L.; DeGeer, C.V.; Boren, Fred W.This experiment was to determine the effect of different stocking rates of deferred grazing, and of pasture burning on cattle performance productivity of pastures, and range condition as determine by plant population changes. In addition to the yearling report, a summary of cattle gains for the past 15 years included.Item Open Access Dicalcium phosphate and Vitamin A for calves on winter bluestem pasture(Kansas Agricultural Experiment Station, 2011-04-28) Smith, E.F.; Richardson, D.; DeGeer, C.V.; Boren, Fred W.The 42 heifer calves, 10 or 11 per treatment, used in this experiment were good to choice Herefords from near Fort Davis, Texas, assigned on a random-weight basis to treatments. They were pastured together in a 150-acre bluestem pasture. During winter, so the three groups could get their experimental rations (Table 19), they were penned and fed three times weekly. Dicalcium phosphate (0.1 pound per heifer daily) and Vitamin A (10,000 I.U. daily)m when fed, were mixed with soybean meal. The experimental rations were discontinued April 3 and only salt was supplied during summer grazing.Item Open Access Comparison of slaughter and carcass characteristics of ram, wether and ewe lambs(Kansas Agricultural Experiment Station, 2011-04-28) Kropf, Donald H.; Mackintosh, D.L.; Hinnergardt, L.C.; Flectcher, R.C.; Menzies, C.S.; Harrison, D.L.; Anderson, L.Lambs of known history were individually slaughtered as they attained 95 pounds live weight. Quality and quantity factors were evaluated and measurements taken after carcasses were chilled 48 hoours. Carcasses were broken into wholesale cuts and weights were obtained. Loin leg and loin were further trimmed of external fat to 3/8 inch thick and trimmed weights obtained.Item Open Access Heritabilities, genetic and phenotypic correlations between carcass and live animal traits in sheep(Kansas Agricultural Experiment Station, 2011-04-28) Menzies, C.S.; Ahlschwede, G.; Wheat, J.D.; Mackintosh, D.L.; Kropf, Donald H.Data was collected on 91 lambs of known breeding born during the fall, 1963. The lambs were from ewes in the original fine-wool flock and were sired by 10 performance-tested Hampshire rams. This was the ewes fifth lamb crop.Item Open Access Lamb feeding experiments(Kansas Agricultural Experiment Station, 2011-04-28) Menzies, C.S.; Erhart, A.B.Delivery of 601 finewool. Wether feeder lambs was accepted at Menard, Texas, October 8, 1964. Average weight was 68.9 pounds; cost, $19.25 per cwt. Lambs were shorn (average fleece weight, 3.2 lbs.) and shipped 543 miles to Garden City on a triple-deck truck. They arrived October 9, a.m., weighing an average of 60.4 pounds. They were divided into groups of about 50 lambs and fed a ration of medium-quality alfalfa hay and chopped sorghum stubble until started on test.
