  • Koch, B.A.; Smith, E.F.; Richardson, D.; Cox, R.F.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1958)
    Previous work at this station (Circular 297. p. 45-47) and at the Fort Hays Branch Experiment Station (Circular 322, p. 1-6) indicates that beef calves wintered on a daily ration of 1.75-2 pounds of ground sorghum grain, ...
  • Koch, B.A.; Loeppke, D.W. (Kansas Agricultural Experiment Station, 1964)
    Specific additives are successfully incorporated into swine rations. Each year new ones are approved and each year the efficacy of the older ones is questioned. Recent feeding trial comparisons at this station are summarized ...
  • Koch, B.A.; Nam, T. (Kansas Agricultural Experiment Station, 1963)
    Arsanilic acid is one of many feed additives approved by the Food and Drug Administration for use in swine rations. Results from an uncontrolled feeding demonstration suggested that arsanilic acid effectively increased ...
  • Richardson, D.; Swenson, M.J. (Kansas Agricultural Experiment Station, 1953)
    Twenty-five purebred female Poland-China pigs about 10 weeks of age were divided into five lots of five pigs each. The pigs were self-fed in pens having concrete floors. Water barrels with automatic watering cups were ...
  • Aubel, C.E. (Kansas Agricultural Experiment Station, 1954)
    In recent years the use of antibiotics in swine nutrition has received much attention. Research has shown that different vitamin B12 antibiotic supplements stimulate gains. Antibiotics have been shown to be effective ...
  • Hillman, M.; Erhart, A.B.; Menzies, C. (Kansas Agricultural Experiment Station, 1962)
    The 638 white-face feeder lambs used in these tests were received October 18, 1961, at the Zuni Indian Reservation south of Gallup, N.M. Average purchase weight was 71.2 lbs. per head. They arrived in Garden City, October ...
  • Bell, T.D.; Hix, E.L.; Erhart, A.B.; Parrish, D.B.; Underbjerg, G.K.L. (Kansas Agricultural Experiment Station, 1953)
    Experiments designed to test the need and value of salt in the rations of feeder lambs have been conducted by the Kansas Agricultural Experiment Station for the past three years. The tests have shown that feedlot gains ...
  • Bell, T.D.; Richardson, D.; Cox, R.F.; Needham, J.W.; John, R. (Kansas Agricultural Experiment Station, 1955)
    This project was designed to study the difference between pelleted and non-pelleted rations of different concentrations. Many commercial lamb feeders are pelleting the entire ration and believe it is superior to the ...
  • Bell, T.D.; Richardson, D.; Cox, R.F.; Needham, J.W. (Kansas Agricultural Experiment Station, 1956)
    Lamb-fattening rations varying in proportions of roughages to concentrate have been studied in this project several years. In recent years much interest has been shown by commercial lamb feeders in completely pelleted ...
  • Menzies, C.; Bell, T.D.; Richardson, D.; Cox, R.F.; Striegel, W.D. (Kansas Agricultural Experiment Station, 1957)
    Physical balance of lamb-fattening rations has been studied in this project for several years. This is the fourth year that this project has been set up to study the effect of pelleting rations of varying proportions of ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Cox, R.F. (Kansas Agricultural Experiment Station, 1957)
    In a previous test it was found that phosphoric acid can be used as a source of phosphorus for beef heifer calves on dry bluestem pasture. A phosphorus balance study with lambs also indicated efficient use of phosphorus ...
  • Richardson, D.; Smith, E.F.; Menzies, C.S.; Cox, R.F. (Kansas Agricultural Experiment Station, 1956)
    In a previous test, it was found that phosphoric acid could be used as a source of phosphorus for beef heifers on dry bluestem pasture. A phosphorus balance study with lambs also indicated efficient utilization of ...
  • Baker, F.H.; Richardson, D.; Harris, J.O.; Cox, R.F.; Bowman, O.M. (Kansas Agricultural Experiment Station, 1955)
    Forty head of choice-quality steer calves were used in the wintering phase of this test. These calves were part of a shipment from the Lonker Ranch, Medicine Lodge, Kan. The steers were assigned to lots on the basis of ...
  • Koch, B.A.; Smith, E.F.; Richardson, D.; McCartor, M.M. (Kansas Agricultural Experiment Station, 1958)
    Recent experimental work with chemical tranquilizers has indicated that these substances may be of value in the fattening ration of beef cattle under certain conditions. Theoretically at least, the chemical tranquilizers ...
  • Richardson, D.; Smith, E.F.; Baker, F.H.; Cox, R.F.; McReynolds, K.L. (Kansas Agricultural Experiment Station, 1954)
    Forty head of good quality Hereford heifer calves were purchased from near Pueblo, Colo. They were divided as equally as possible into four lots of 10 heifers each. The starting ration for each lot is shown in Table 12. ...
  • Menzies, C.S. (Kansas Agricultural Experiment Station, 1966)
    In a previous test (Livestock Feeder’s Day Bulletin 473) adding 10% animal fat to a ration containing 45% alfalfa hay did not affect rate of gain but materially improved feed efficiency and lowered cost per unit gain. This ...
  • Drake, C.L.; Smith, E.F.; Perry, H.B.; Good, D.L.; Richardson, D. (Kansas Agricultural Experiment Station, 1967)
    The number of cattle concentrated in small areas is increasing in Kansas. Conditioning new cattle is a major problem in some operations. This experiment studied effects of adding a combination of chlortetracycline-sulfamethazine ...
  • Richardson, D.; Smith, E.F.; Cox, R.F. (Kansas Agricultural Experiment Station, 1956)
    Twenty-seven Hereford steer calves were divided as equally as possible into three lots of 9 animals each. One lot received stilbestrol at the rate of 6 milligrams per head daily for the first 56 days. The rate was ...
  • Oltjen, R.R.; Smith, E.F.; Cox, R.F. (Kansas Agricultural Experiment Station, 1958)
    This is the fourth in a series of experiments conducted to determine the value of trace minerals in a typical fattening ration. Three previous experiments, similar to this one, were reported in Kansas Agr. Exp. Sta. Cirs. ...
