  • Koch, B.A.; Cowman, G.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Most authorities agree that the value of a protein source is determined by its content of essential amino acids. On that basis soybean meal compares favorably' with the other commonly fed animal protein sources. However, ...
  • Kropf, Donald H.; Kasten, L.H.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Many studies have reported that barrows gain more rapidly than gilts, but gilts excell in carcass muscling and trimness. Recently, considerable interest has been directed toward determining ration protein needs of barrows ...
  • Phar, P. (Kansas State University. Agricultural Experiment Station, 1968)
    The Kansas cattle feeding industry has grown tremendously since 1956. The 1968 January Cattle on Feed Report shows more than ten times as many cattle in commercial feedlots as in 1956. Farm feedlots have also increased, ...
  • Smart, L.I.; Drake, C.L. (Kansas State University. Agricultural Experiment Station, 1968)
    Silage is being utilized in larger quantities in beef cattle growing and fattening rations. Hammes et al. (1964) showed that higher levels of corn silage can be used because gains from high silage and high grain rations ...
  • Schalles, R.R.; Drake, C.L.; Allen, Dell M. (Kansas State University. Agricultural Experiment Station, 1968)
    Freeze marking for within-herd identification was used on 65 Hereford females. The cattle were 18 months to nearly three years old. Three numerals were placed on the right rump of each animal in the fall of 1967. The ...
  • Koch, B.A.; Cowman, G.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Kansas swine growers are quite sure' that corn-fed growing-finishing pigs will outperform those fed sorghum grain. Just as many others feel that sorghum grain is equal to corn in swine rations. Most of the time sorghum ...
  • Koch, B.A.; Cowman, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Recent laboratory and research station reports have indicated that 2,2-dichlorovinyl dimethyl phosphate (DDVP) (Shell Dichlorvos) fed to pregnant sows late in gestation may have a favorable effect on the newborn pigs. This ...
  • Smith, E.F.; Owensby, Clenton E.; Kolstad, S.P. (Kansas State University. Agricultural Experiment Station, 1968)
    Studied were the effects of early season heavy stocking and burning on cattle performance, productivity of pastures and range condition as determined by plant population changes. The objective of early season heavy ...
  • Phar, P.A.; Zimmer, P.R. (Kansas State University. Agricultural Experiment Station, 1968)
    Two feedlot trials were conducted during the summer of 1967 at the Morris Feed Yards, Marris, Kansas, to study effects of aureomycin (chlortetracycline) and sulfamethazine fed alone or in combination on weight gain, feed ...
  • Koch, B.A.; Howard, R.D.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    More information is needed on the optimum level of protein in sorghum grain-soybean meal rations for swine. Theoretically the protein value of a swine ration should be improved if the most limiting amino acids are added. ...
  • Drake, C.L.; Smart, L.I.; Smith, E.F.; Lipper, R.I. (Kansas State University. Agricultural Experiment Station, 1968)
    This is a cooperative project with the Department of Agricultural Engineering to study surface runoff, in addition to animal performance. Twenty Hereford heifers were randomly allotted to four equal sized lots: 2 surfaced ...
  • Smart, L.I.; Drake, C.L. (Kansas State University. Agricultural Experiment Station, 1968)
    Melengestrol acetate (MGA) 1S a new drug recently approved for use in the supplement portion of rations of feed-lot heifers. The recommended level is from 0.25 to 0.50 mg. per head per day. A 48-hour withdrawal period is ...
  • Kropf, Donald H.; Kasten, L.H.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Limited work is available on proper protein levels in swine rations when sorghum grain is a major ration component. Remarkable improvement has been made in gaining ability, feed coversion and muscling in swine. Because of ...
  • Kiracofe, G.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Several methods of synchronizing estrus have been tried in swine. One of the oldest and most commonly used natural methods is weaning pigs from a group of sows simultaneously. When this is done, the majority of sows will ...
  • Koch, B.A.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    The need for zinc in swine rations has been firmly established. Likewise the inter-relationships between dietary zinc and other minerals, especially calcium, have been well authenticated. However, there are still many ...
  • Cowman, G.L.; Deyoe, C.W.; Koch, B.A.; Pfost, H.B.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    This paper is a progress report of a research project initiated this past year designed to study the effects of heat and pressure processing of sorghum grain on the performance of swine. The theoretical reasoning behind ...
  • Smith, E.F.; Richardson, D.; Drake, C.L.; Brent, B.E. (Kansas State University. Agricultural Experiment Station, 1968)
    Trials at several research centers as well as in Kansas (Bulletin 483, page 32) have shown roughage may be satisfactorily omitted from finishing rations for cattle and doing so, often reduces feed required per pound of ...
  • Smith, W.H.; Akinokun, J.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1968)
    Two inbred lines of purebred Shorthorn cattle were established and progressively developed, to study production traits and effects of inbreeding. Inbreeding was initiated in the Wernace Premier Line in 1949 and in the ...
  • Tuma, H.J.; Grant, D.; Covington, R. (Kansas State University. Agricultural Experiment Station, 1968)
    The beef carcass quality grading system currently used has been challenged by many who say current standards are too high and that the amount of marbling to attain a given grade should be decreased.
  • Brent, B.E.; Adepoju, A.; Portela, F.; Richardson, D. (Kansas State University. Agricultural Experiment Station, 1968)
    Rumen bacteria elaborate an enzyme, urease. Urease is capable of breaking down urea to ammonia and carbon dioxide. Rumen bacteria then incorporate the ammonia into new amino acids and bacterial protein. Thus, urea can ...
