  • Chestnut, A.; Brent, B.E. (Kansas State University. Agricultural Experiment Station, 1977)
    We are developing mathematical models to show how feed intake, rate of gain, and feed efficiency change during the finishing period. When finished, the models might be used to predict when to sell cattle to maximize profit ...
  • Allen, Dell M.; Hunt, Melvin C.; Kropf, Donald H.; Gutowski, G.; Harrison, A.; Smith, M.E.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station, 1977)
    Thirty-eight crossbred steers of known background were randomly assigned to four feeding regimes. All initially were fed on a brome and bluestem pasture supplemented during winter with alfalfa and protein. Ten grass-fed ...
  • DeBenedetti, R.C.; Kiracofe, G.H.; Ward, H.S.; McKee, R.M. (Kansas State University. Agricultural Experiment Station, 1977)
    One hundred seven of 112 heifers were in estrus 1 to 5 days after an injection of prostaglandin F2α given when a 7-day synchronization implant was removed. Checks for estrus were made every four hours and heifers were ...
  • Kimple, K.; McKee, M.; Fink, G.; Conway, K. (Kansas State University. Agricultural Experiment Station, 1977)
    Performances of 125 commercial Hereford-cross and percentage Simmental calves were evaluated by comparing early weaning at 50 days of age (+25), nursing calves receiving a creep in drylot, and calves nursing in drylot ...
  • Corah, L.; Bolsen, K.; McKee, M.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1977)
    Seventy five purebred heifers were used to determine whether Monensin, (trade name Rumensin) fed during the initial growing period after weaning, would affect the reproductive performance of yearling heifers. Rumensin ...
  • Tobyne, D.; Fink, G.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1977)
    We used 72 Hereford and Hereford x Angus cross yearling steers to further evaluate 200 mg Monensin (trade name Rumensin) per head daily. Monensin improved gain 6.7% and significantly improved efficiency, 12.3%.
  • Corah, L.R.; McKee, M.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1977)
    One hundred twenty-seven suckling calves were allotted to one of three treatments: (1) Control group - not implanted (2) Implanted (Ralgro) once during sucking period (3) Implanted (Ralgro) twice during sucking period ...
  • Schwartz, F.; Smith, E.; Riley, Jack G.; Corah, L. (Kansas State University. Agricultural Experiment Station, 1977)
    Two grazing trials conducted at different locations in Kansas evaluated feeding Monensin to grazing yearling cattle. In one trial Monensin was fed with and without implant treatments of diethylstilbestrol or Ralgro. ...
  • Posler, Gerry L.; Bolsen, K. (Kansas State University. Agricultural Experiment Station, 1977)
    The attempt to increase total forage TDN per acre by double-cropping was only moderately successful in 1975 and 1976. Limiting factors were relatively poor stands and extremely dry summer growing seasons.
  • Bolsen, K.; Moore, W. (Kansas State University. Agricultural Experiment Station, 1977)
    Interest in small cereal grain silages for beef cattle has increased in recent years. Two years' research at this station (Prog. Rpt. 262) has shown: (1) winter barley and winter wheat had similar forage yields and (2) ...
  • Umoh, J.E.; Harbers, L.H.; Smith, E.F. (Kansas State University. Agricultural Experiment Station, 1977)
    Forage intake was used as an estimate of the nutritive value of Flint Hills pastures. The organic matter intake (OMI) ranged from 16.3 lb. to 22.05 lb. (7.40 to 10.0 kg) between June-August, 1976, and there was no clear ...
  • Umoh, J.E.; Harbers, L.H.; Smith, E.F.; Whitney, J.; Boggs, Don (Kansas State University. Agricultural Experiment Station, 1977)
    We used an in vitro digestibility technique to determine the nutritive value of predominately native bluestem forage on burned and nonburned Flint Hills pastures. We also collected forage samples via esophageal fistulas ...
  • Hultine, V.; Kiracofe, G.H.; Schalles, R.R.; McKee, R.M.; DeBenedetti, R.C. (Kansas State University. Agricultural Experiment Station, 1977)
    Calving was induced in 26 of 29 Polled Hereford cows that were injected between 271 and 287 days of gestation intramuscularly with 20 mgs. Of dexamethasone (Azium) and 10 mgs. ECP (estradiol cypionate). Oxytocin, give ...
  • Kimple, K.; McKee, M.; Fink, G. (Kansas State University. Agricultural Experiment Station, 1977)
    One hundred-two mature Simmental and Hereford cows in mid to late gestation were used to compare three maintenance rations during an 83-day trial: (1) milo stover silage, (2) large package milo stover (stacks and bales), ...
  • Bolsen, K.; Chyba, Leslie J.; Ibbetson, W. (Kansas State University. Agricultural Experiment Station, 1977)
    In growing rations containing fescue hay, micronized corn + urea-liquid gave: (1) 20.5% faster gains and 11.5% more efficient gains than cracked corn + urea-liquid and (2) similar rate and efficiency of gains as cracked ...
  • Bolsen, K.; Oltjen, J.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1977)
    Twenty-four individually fed heifers were used 1n two heifer trials to evaluate four combinations of micronized or dry-rolled milo and soybean meal or urea supplements 1n prairie hay growing rations. Feeding 4 to 5 lbs. ...
  • Bolsen, K.; Riley, Jack G.; Grimes, C. (Kansas State University. Agricultural Experiment Station, 1977)
    Ninety heifer calves were used to compare six rations containing various combinations of milo stover, forage sorghum and alfalfa silages. In the 96-day trial, heifers fed 100% forage sorghum silage outperformed heifers ...
  • Harbers, L.H.; Brazle, F.K.; Owensby, Clenton E. (Kansas State University. Agricultural Experiment Station, 1977)
    The scanning electron microscope has been used to observe the digestion of alfalfa hay and warm- and cool-season grasses. Photomicrographs show that leaves of all species are digested by bacteria and protozoa attacking ...
  • Koons, L.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1977)
    Twenty-four Kansas feedyards with 432,000 head capacity participated in a survey on operation procedures. The survey covered five areas: processing, animal health, rations, facilities, and marketing. Methods differed most ...
  • Loveday, H.D.; Allen, Dell M.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station, 1977)
