  • Wheat, J.D.; Suba, M.S.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1982)
    Average farrowing interval and duration were 15.8 and 143.8 minutes for 1766 pigs born in 169 litters. Pigs born later in the litter were larger (r=.43) at birth. The correlation was -.14 between farrowing interval, average ...
  • Wheat, J.D.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1976)
    Pigs in the control line ate more, grew faster, and were less efficient than those in the select line.
  • Wheat, J.D.; Menzies, C.S.; Holland, L.A. (Kansas Agricultural Experiment Station, 1956)
    July 6, 1955, two adult guinea pig males each was implanted with 24 milligrams of stilbestrol. A young female that previously had given birth to a litter was placed in the cage with these males, but for some time they ...
  • Wheat, J.D.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1981)
    Based on the first 76 farrowings recorded, average duration (the time between the birth of the first pig and of the last pig in the litter) was 129.09±7.28 minutes, and the average time interval between pigs was 15.71± 1.02 ...
  • Wheat, J.D.; Suba, M.S.; Dayton, A.D.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    The average for 1813 farrowing intervals was 16.78 minutes with a standard deviation of 25.37 minutes. Farrowing duration averaged 141.51 minutes, ranging from 11 to 618 minutes. The difference between farrowing intervals ...
  • 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.
  • 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.
  • Hillman, M.; Menzies, C.S.; Wheat, J.D.; Mackintosh, D.L.; Merkel, R.A. (Kansas Agricultural Experiment Station, 1962)
    This is a continuous project to the North-Central-50 Regional Sheep Breeding Project. The Kansas State Project was initiated to determine relationships between various carcass measurements and live animal traits, to estimate ...
  • Menzies, C.; Hillman, M.; Wheat, J.D.; Mackintosh, D.L.; Merkel, R.A. (Kansas Agricultural Experiment Station, 1961)
    This is a contributing project to the North Central-50 Regional Sheep Breeding Project. The Kansas State project was initiated in the spring of 1959 to determine relationships between various carcass measurements and live ...
  • Smith, W.H.; Wheat, J.D.; Spies, H.G. (Kansas Agricultural Experiment Station, 1965)
    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 ...
  • Smith, W.H.; Wheat, J.D.; Spies, H.G. (Kansas Agricultural Experiment Station, 1966)
    The purebred Shorthorn beef cattle breeding experiment was initiated to study inheritance of production traits, to evaluate effects of inbreeding, and to explore the feasibility of using inbred lines for breeding improvement ...
  • Smith, W.H.; Wheat, J.D. (Kansas Agricultural Experiment Station, 1961)
    The purebred Shorthorn cattle breeding project was continued during 1960 according to the breeding program adopted when the study was initiated in 1949. Two inbred lines were established and have been continued. The Wernacre ...
  • Smith, W.H.; Wheat, J.D.; Spies, H.; Gottlieb, H.A. (Kansas Agricultural Experiment Station, 1962)
    The purebred Shorthorn cattle breeding program was continued during 1961 according to the breeding program initiated in 1949. Inbreeding of the two lines has been continued. The Wernacre Premier line is in its fourth ...
  • Smith, W.H.; Wheat, J.D.; Spies, H.G. (Kansas Agricultural Experiment Station, 1963)
    The purebred Shorthorn cattle breeding program was continued during 1962 without modification of breeding plans. Inbreeding was continued in the two lines. The Wernacre Premier line is in its firth generation and the Mercury ...
  • Smith, W.H.; Wheat, J.D.; Spies, H.G. (Kansas Agricultural Experiment Station, 1964)
    The purebred Shorthorn beef cattle breeding project was continued during 1963 without modification. Inbreeding was continued in the two separate lines, which have remained closed to outside breeding since the study was ...
  • Mackintosh, D.L.; Kropf, Donald H.; Good, D.L.; Wheat, J.D.; Teagarden, J.; Harrison, D.L. (Kansas Agricultural Experiment Station, 1964)
    Seventy head of fed Hereford steers, sired by four different bulls, were slaughtered in Kansas City, and the rib cut from 40 (10 for each sire) returned to Manhattan for detailed analysis. Cooking data are now available ...
  • Wheat, J.D.; Kropf, Donald H.; Chang, C.H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1973)
    Pigs farrowed in May, 1972, were the first born in the select and control lines. Performances of animals in the two lines were essentially the same. However, ham firmness and color differed significantly (P<0.0l) between ...
  • Wheat, J.D.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1972)
    We are attempting to develop a well-muscled line of Durocs by selecting for minimum back fat and maximum loin eye area as estimated by the Anscan and to form a control line by randomly selecting from the same base population. ...
