  • Mintert, J.; Schroeder, Ted C.; Marsh, T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    We investigated factors that have affected beef demand over the last two decades. Beef demand is typically modeled as a function of beef prices, competing meat prices, prices of all other goods, and consumer expenditures. ...
  • Mintert, J.R.; Schroeder, Ted C.; Langemeier, Michael R.; Albright, M.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    The relative contributions of fluctuating cattle performance; interest rates; and feeder cattle, fed cattle, and feed grain prices to profit variability of cattle feeding were examined in this study. Closeout data from ...
  • King, M.; Kiracofe, G.H.; McKee, R.M. (Kansas State University. Agricultural Experiment Station, 1981)
    With heifers given two injections of Lutalyse 11 days apart, and inseminated 80 hours after the second injection, only 20% in heat before 48 hours conceived compared with 65% that were in heat 48 to 80 hours after injection. ...
  • Brink, J.T.; Middleton, C.D.; Kiracofe, G.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1985)
    In five trials during 1983 and 1984, 238 cows and 54 heifers were synchronized with Syncro-Mate-B® and artificially inseminated 48 hours after implant removal. The conception rate was 42.5% in cows that were cycling and ...
  • Albright, M.; Schroeder, Ted C.; Langemeier, Michael R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    This study examined the relative effects of corn price and cattle performance factors on steer finishing cost of gain. Seasonal analysis of cost of gain and the factors affecting it was also conducted. Using over 10 ...
  • Smith, J.F.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Feed intake is the single most critical factor of dairy production, and performance of dairy cattle can be enhanced or hindered by environmental factors that affect it. These environmental factors can by divided ...
  • Stevenson, Jeffrey S.; Schmidt, M.K.; Call, Edward P. (Kansas Agricultural Experiment Station, 1984)
    Stage of the estrous cycle, time of insemination, and season of the year were examined for their influence on estrus and fertility of 223 Holstein heifers after prostaglandin F2α(PGF). Heifers given PGF early in the ...
  • Schroeder, Ted C.; Jones, J.M.; Nichols, David A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
    A survey of feeder pig sales was conducted at two Kansas feeder pig auctions during the spring and summer of 1988. Several factors were identified that helped explain a large portion of the short-run price differentials ...
  • Bell, F.W.; Smith, E.F.; Smith, W.H. (Kansas Agricultural Experiment Station, 1952)
    Cattle in the same feedlot differ considerably in their rate of gain. These differences in ability to gain can be explained only by difference in characteristics of individual animals, since all are under the same conditions ...
  • Utter, S.D.; Houghton, P.L.; Corah, L.R.; Spire, M.F.; Higgins, James J.; Butine, M.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Data from yearling Angus and Angus crossbred beef heifers from a commercial ranch were used to identify factors affecting pregnancy rates (n=342) and calving difficulty (n=295). Production data analyzed included prebreeding ...
  • Hunt, Melvin C.; Warren, K.E.; Kropf, Donald H.; Hague, M.A.; Waldner, C.L.; Stroda, Sally L.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    Some ground beef patties developed an internal, brown cooked color and looked well-done at temperatures as low as 13 1EF, whereas normal patties were re d to pink. The premature brown color was not relate d to percent ...
  • Lambert, C.; Corah, L.; Grunewald, O. (Kansas State University. Agricultural Experiment Station, 1983)
    Data were collected on 85,195 cattle sold in 15 Kansas auctions during October and November 1981. Buyers discounted sick cattle heavily, 'and discounts were heavier on sick calves than yearlings. The discount for bulls ...
  • Sulabo, R.C.; Jones, C.K.; Campbell, D.R.; Ratliff, B.W.; Tokach, Michael D.; Goodband, Robert D.; DeRouchey, Joel M.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010)
    A 360-d study was performed to evaluate the effects of environmental conditions on storage stability of exogenous phytases. Coated and uncoated products from 3 phytase sources (Ronozyme P, OptiPhos, and Phyzyme) were ...
  • Smith, E.F.; Richardson, D.; Fairbanks, G.E.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1963)
    This is the third year of an experiment designed to investigate factors that affect the feeding value of sorghum silage. Data reported in Circular 383, 1960-61, indicated that almost without exception, average daily gain, ...
  • Marston, T.T.; Wankel, L.E.; Moser, Daniel W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Many factors are considered when commercial cow/calf producers buy bulls. Breeding system needs and breeder’s preference determine which breed of bull will be purchased at a multi-breed sale. Our analysis of prices ...
  • Schmidt, Karen A.; Stupar, J.; Shirley, John E.; Adapa, S.; Sukup, D. (Kansas Agricultural Experiment Station, 1996)
    The value of titratable acidity (TA) as an indicator of raw milk quality has been challenged recently, because milk is refrigerated within minutes after it leaves the cow until it reaches the consumer. Also, high milk ...
  • Langemeier, Michael R.; Mintert, J.; Schroeder, Ted C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    This study examined the relative importance of price and animal performance factors on cattle finishing profitability. Using data from a single feedlot, sale prices, feeder prices, and corn prices explained 90 to 95% ...
