  • Influence of method of processing supplemental alfalfa on intake and utilization of dormant, bluestem-range forage by beef steers
    Lintzenich, B.A.; Cochran, R.C.; Vanzant, E.S.; Beaty, J.L.; Brandt, R.T. Jr.; Nagaraja, T.G.; St. Jean, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    A digestion trial was conducted to determine the effect of method of processing supplemental alfalfa on the intake and utilization of dormant, bluestem-range forage. Supplement treatments were 1) control: no supplement; ...
  • Influence of supplemental fat and monensin plus tylosin on performance and carcass traits of finishing steers
    Brandt, R.T. Jr.; Nagaraja, T.G.; Elliott, J.K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    Interactions between supplemental fat (3.5%) and monensin plus tylosin (25 plus 10 g/ton, respectively) on animal performance and carcass traits were evaluated in a 125-d finishing trial. Interactions on feed consumption ...
  • Lasalocid or Rumensin to prevent lactic acidosis in cattle
    Nagaraja, T.G.; Dennis, S.M.; Avery, T.B.; Bartley, E.E.; Galitzer, S.J. (Kansas State University. Agricultural Experiment Station, 1980)
    Lasalocid or Rumensin (monensin) protected cattle gorged with grain from lactic acidosis. Both lasalocid and monensin prevented the decrease in rumen and blood pH and increase in rumen and blood lactic acid (0(-) isomer) ...
  • Leukotoxin production by Fusobacterium necrophorum biotypes
    Tan, Z.; Nagaraja, T.G.; Chengappa, M.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Fusobacterium necrophorum biotypes A and B were grown anaerobically to detect their leukotoxin production. Both biotypes exerted the highest leukotoxic effect on bovine leukocytes in the late logarithmic and early ...
  • Lysine degradation by ruminal Fusobacterium necrophorum
    Elwakeel, E.A.; Amachawadi, R.G.; Nour, A.M.; Nassar, M.E.; Nagaraja, T.G.; Titgemeyer, E.C. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Three experiments were conducted to characterize lysine fermentation by Fusobacterium necrophorum, a ruminal bacterium that is known to degrade amino acids. In Experiment 1, 7 strains of Fusobacterium necrophorum were ...
  • Moderation of ruminal fermentation by protozoa in cattle fed high-grain diets
    Nagaraja, T.G.; Towne, G.; Beharka, A.B. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Ruminal protozoa in cattle fed high-grain diets appear to contribute to the maintenance of a stable ruminal fermentation. This was evidenced by higher ruminal pH's and lower volatile fatty acid concentrations in faunated ...
  • Optaflexx1 affects rumen fermentation
    Walker, C.E.; Drouillard, J.S.; Nagaraja, T.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)
    Three experiments were conducted to determine effects of ractopamine-HCl, sold under the trade name Optaflexx, on rumen fermentation. In experiment 1, fermentative gas production was measured in vitro to determine the ...
  • Performance and ruminal microbial and metabolic development of young calves fed diets containing aspergillus oryzae extract
    Beharka, A.A.; Morrill, J.L.; Nagaraja, T.G. (Kansas Agricultural Experiment Station, 1990)
    Seventy-three, neonatal, Holstein, heifer calves in one experiment and 45 neonatal, Holstein, bull calves in another were used to study the effects of dietary Aspergillus oryzae extract (Amaferm) on calf performance. ...
  • Performance of early weaned calves fed lasalocid
    Anderson, K.L.; Nagaraja, T.G.; Morrill, J.L.; Reddy, P.G.; Avery, T.B.; Anderson, N.V. (Kansas Agricultural Experiment Station, 1987)
    Twenty-two newborn, bull calves were used to determine the effects of lasalocid on growth and feed intake of early-weaned calves from week 1 to 12. Calves were assigned to lasalocid or control groups on day 3. Lasalocid-fed ...
  • Rumen bacterial endotoxins and their possible role in the sudden-death syndrome
    Nagaraja, T.G.; Bartley, E.; Fina, L.; Anthony, H.; Leipold, H. (Kansas State University. Agricultural Experiment Station, 1979)
    We have found that rumen bacteria contain endotoxins that are released into rumen fluid. Also rumen fluid from grain-fed cattle contains considerably more free endotoxin than rumen fluid from hay-fed cattle. Injecting ...
  • Rumensin helps to reduce the incidence and severity of legume bloat in cattle
    Nagaraja, T.G.; Katz, M.P.; Fina, L.R. (Kansas Agricultural Experiment Station, 1985)
    Monensin at 300 mg and 450 mg per 1000 lbs body weight reduced the severity of alfalfa pasture bloat by 41.2 and 73.1 %, respectively. Lasalocid at the same levels reduced the bloat score by 25.5 and 12.4%. The difference ...
  • Ruminal metabolic development in conventionally or early weaned calves
    Anderson, K.L.; Nagaraja, T.G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1986)
    Accelerating the weaning age of calves appeared to increase their ruminal metabolic activity. This was indicated by the lower ruminal pH and increased, total volatile fatty acid concentration of calves weaned at 4 wk of ...
