  • Tuma, H.J.; Kropf, Donald H.; Kolstad, S.P.; Mackintosh, D.L. (Kansas Agricultural Experiment Station, 1967)
    Information on animal growth and development, although complex and not fully understood, is necessary to determine the stage at which a beef animal will produce the most desirable carcass. True growth involves an increase ...
  • Weber, A.D.; Pickett, A.G.; Mackintosh, D.L. (Kansas Agricultural Experiment Station, 1949)
    The Kansas, Oklahoma, and Ohio Agricultural Experiment Stations are cooperating in this study, which is supported by grants from the American Hereford Association. In October, 1948, each station received 96 steer calves ...
  • Smith, E.F.; Mackintosh, D.L.; Weber, A.D. (Kansas Agricultural Experiment Station, 1950)
    The project involves comparisons of steer calves sired by small, medium, and large size bulls at each of the three stations under three standard systems of feeding and management. System I, immediate full feeding for 225 ...
  • Kropf, Donald H.; Mackintosh, D.L.; Hinnergardt, L.C.; Flectcher, R.C.; Menzies, C.S.; Harrison, D.L.; Anderson, L. (Kansas Agricultural Experiment Station, 1965)
    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 ...
  • Kropf, Donald H.; Mackintosh, D.L.; Hinnergardt, L.C.; Menzies, C.S.; Harrison, D.L.; Anderson, L. (Kansas Agricultural Experiment Station, 1966)
    Lambs sired by Hampshire rams and from western ewes were individually slaughtered as they reached 96 lbs. live weight. Quality and quantity factors were evaluated after carcasses were chilled 48 hours. Carcasses were ...
  • Soule, R.P. Jr.; Mackintosh, D.L.; Richardson, D.; Aubel, C.E. (Kansas Agricultural Experiment Station, 1955)
    The two antibiotics fed in these four trials were Aureomycin and Terramycin HCl at the level of 10 mg. per pound of total ration. Lot 1 pigs were the controls receiving the basal ration; Lot 2, basal plus 10 mg. of ...
  • Kropf, Donald H.; Mackintosh, D.L.; Hall, J.L.; Harrison, D.L.; Hunsader, M.; Ahlschwede, G.A. (Kansas Agricultural Experiment Station, 1964)
    Muscle color is an important factor affecting shoppers’ choice of pre-packaged meats from self-service display cases. The effect of several levels of dietary iron and of two levels of a chelating agent on pork muscle ...
  • Weiner, P.D.; Kropf, Donald H.; Mackintosh, D.L.; Koch, B.A. (Kansas Agricultural Experiment Station, 1964)
    The effect of processing pork carcasses before rigor mortis was studied in 21 market-weight swine. The left side of each carcass served as a control and was chilled for 48 hours at 32-36 F before being cut and processed ...
  • Mackintosh, D.L.; Soule, R.P. Jr.; Bell, T.D.; Hall, J.L.; Harrison, D.; Westerman, B. (Kansas Agricultural Experiment Station, 1956)
    Diethylstilbestrol when implanted in growing fattening lambs increases the rate of gain and feeding efficiency, but lowers the yield and the carcass grade. These observations are accepted as a result of work done by ...
  • Bell, F.W.; Mackintosh, D.L.; Pickett, A.G. (Kansas Agricultural Experiment Station, 1948)
    This is the second trial to study the effect of differences which can be observed in feed calves classified as good to choice. The two lots in this trial were sorted from the 100 range-bred heifer calves purchased last ...
  • Bell, F.W.; Mackintosh, D.L.; Pickett, A.G. (Kansas Agricultural Experiment Station, 1947)
    The two lots of heifer calves in this test were selected from 75 range bred heifer calves purchased last fall. The 75 heifers were a uniform group, all of which would be classed as good to choice feeder calves. The 10 ...
  • Bell, F.W.; Mackintosh, D.L.; Pickett, A.G. (Kansas Agricultural Experiment Station, 1949)
    This report is on two lots of heifer calves now on test in the study of the characteristics of feeder calves which are associated with differences in: 1. Rate of gain 2. Kind and amount of feeds required to produce ...
  • Bell, F.W.; Mackintosh, D.L.; Pickett, A.G. (Kansas Agricultural Experiment Station, 1948)
    The two lots in this trial were selected from 75 range-bred heifer calves purchased in November, 1946 for feeding tests at this station. These calves were a uniform group classified as good to choice feeder calves. The ...
  • Mackintosh, D.L.; Watt, D.B. (Kansas Agricultural Experiment Station, 1949)
    The enormous increase in the use of frozen foods and in the number of frozen locker plants offering freezer storage to the individual. together, have emphasized the need for more research in the field of frozen meat ...
  • Smith, E.F.; Good, D.L.; Cox, R.F.; Mackintosh, D.L. (Kansas Agricultural Experiment Station, 1951)
    The purpose of this experiment is to develop a desirable system of fattening heifer calves similar to the deferred full-feeding system for steer calves. The system developed for good quality steer calves consists of three ...
  • Menzies, C.S.; Wheat, J.D.; Mackintosh, D.L.; Kropf, Donald H. (Kansas Agricultural Experiment Station, 1964)
    Data were collected on 94 lambs of known breeding born the fall of 1962. The lams were from ewes in the original fine-wool flock sired by eight unrelated Suffolk yearling rams. This was the ewes fourth lam crop.
  • Menzies, C.S.; Ahlschwede, G.; Wheat, J.D.; Mackintosh, D.L.; Kropf, Donald H. (Kansas Agricultural Experiment Station, 1965)
    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.
  • Hillman, M.; Menzies, C.S.; Wheat, J.D.; Mackintosh, D.L.; Merkel, R.A. (Kansas Agricultural Experiment Station, 1962)
