  • Fitzner, G.E.; Kropf, Donald H.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    Forty six barrows were fed a common diet after completing a 35 d growth trial in which 50% received 5 mg/d of pST and the other 50% a placebo injection. At the conclusion of the growing trial (130 lb), the pST-injected ...
  • Koch, B.A. (Kansas Agricultural Experiment Station, 1963)
    A crossbred barrow sired by a Duroc boar (University Charm 16753), and out of a Poland China sow (Prince’s Maiden 20-521492), was first place crossbred barrow at the 1962 Kansas State Fair. The barrow produced the champion ...
  • James, J.E.; Reeser, P.D.; Davis, Duane L.; Straiton, E.C.; Talbot, A.C.; Polge, C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    A major threat to swine enterprises is the possible introduction of disease when new breeding animals are purchased and introduced. So, methods of introducing new genetic material while minimizing the potential for introducing ...
  • Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    Manure nutrients help build and maintain soil fertility. Manure also improves tilth, increases waterholding capacity, lessens wind and water erosion, improves aeration, and promotes beneficial organisms. When wastes include ...
  • Kropf, J.; McCoy, J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1975)
    Prices for market barrows and gilts began a significant upward trend in July, 1974. By spring of 1975 hog feeding profits had improved substantially over a year earlier. Improved profits would be expected to lead to ...
  • Heekin, M.D.; Kiracofe, G.H.; Schalles, R.R.; Ward, H.S. (Kansas State University. Agricultural Experiment Station, 1977)
    We used 76 cows to determine the effect of inseminating at different times after detecting estrus and to evaluate Synchronization B as an estrus synchronizing agent. Cows were divided into five groups: (1) nonsynchronized ...
  • Stevenson, Jeffrey S.; Thompson, K. E.; Smith, J. F.; Hawkins, D. E. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Two experiments were performed using the same treatments. All heifers received two injections of PGF[subscript]2alpha 14 days apart. Controls then were inseminated after detected estrus. Heifers assigned to the two ...
  • Heekin, M.; Kiracofe, G.H.; Hultine, V.; Schalles, R.R.; McKee, R.M. (Kansas State University. Agricultural Experiment Station, 1976)
    We used 79 cows to evaluate Syncromate B (G.D. Searle, Co.) as an estrus-synchronizing agent. Management of five groups of cows was: (1) nonsynchronized, bred naturally; (2) nonsynchronized, bred artificially; (3) synchronized, ...
  • Larson, Robert L.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    The percentage of heifers conceiving to artificial insemination (AI) following melengestrol acetate/prostaglandin F2"(MGA®/PG) estrous synchronization can be increased by mass insemination of all heifers not showing estrus ...
  • Corah, L.R.; Yaeger, J.R.; Whittier, J.C.; Meiske, J.C.; Patterson, D.J.; Olson, K. C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    We evaluated the estrous response and fertility of yearling beef heifers after treatment with melengestrol acetate (MGA) and prostaglandin F2" (PG). The 304 heifers, at three locations, were allotted to two ...
  • Larson, Robert L.; Corah, L.R.; Viker, S.V. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1992)
    Inseminating heifers 72 hr after the PG injection in the melengestrol acetate/ prostaglandin F (MGA®/PG) estrous synchronization system, without regard to behavioral estrus, tended to improve (P=.2) the percent of ...
  • Kobayashi, Y.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1995)
    Summary Lactating Holstein cows and replacement heifers were treated with a novel synchronized ovulation protocol, which involves one fixedtime insemination without heat detection. One injection of GnRH (Cystorelin®) ...
  • Heersche, G.; Kiracofe, G.H.; McKee, R.M.; Morrison, D.G. (Kansas State University. Agricultural Experiment Station, 1975)
    Estrous synchronization would benefit the cattle industry. Successful methods are not commercially available, so new compounds and treatment procedures are being tested. Treatment with melengestrol acetate, prostaglandin, ...
  • DeBenedetti, R.C.; Kiracofe, G.H.; Hultine, V.; McKee, R.M.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1976)
    Forty-five of 50 heifers were in estrus 1 to 5 days after 7-day synchronization implants were removed. Prostaglandin was injected one day before implants were removed. Thirty-one of the 45 (68.9%) heifers conceived to first ...
  • Heersche, G. Jr.; Kiracofe, G.; McKee, M.; Davis, Duane L.; Brower, G.R. (Kansas State University. Agricultural Experiment Station, 1974)
    Forty-seven of 50 heifers were in estrus 1 to 5 days after an injection of prostaglandin given when an ear implant of Synchro-mate B was removed. The implant had been in place one week. Thirty of the 47 (63.8%) heifers with ...
  • Lamb, G.C.; Cartmill, J.A.; Hensley, B.A.; El-Zarkouny, S.; Heldt, J.S.; Marple, T.J.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    The Select Synch protocol (GnRH at day - 7, PGF2 at day 0, AI at detected heat) was compared to protocols using either MGA + prostaglandin (Colorado system) or two injections of prostaglandin to synchronize estrus ...
  • McGuire, W.J.; Kiracofe, G.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    Syncro-Mate B® was capable of inducing estrous behavior in ovariectomized cows. Lengthening the norgestomet implant period from 9 to 18 days did not prevent estrus. The ability of Syncro-Mate B to induce estrous behavior ...
  • Schoneweis, D.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1978)
    Marked enlargement and edema of the vulva are often noted in newborn gilts. An accompanying, but less conspicuous, lesion is enlarged, engorged mammary glands. Although not fully understood, the changes are thought to ...
  • Bates, Kerri E.; Weaber, Robert L.; Bormann, Jennifer M.; Moser, Daniel W.; Salak-Johnson, J. L.; Chase, C. C. L.; Peel, R. K.; Van Campen, H.; Loneragan, G. H.; Wagner, J. J.; Bodhireddy, P.; Prayaga, K.; Enns, R. M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2014)
    Cattle producers historically have selected for docile temperaments simply for management convenience because calmer animals are conducive to safe environments for their peers as well as their handlers. As many producers ...
