  • Löest, C.A.; Greenwood, R.H.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    Holstein steers were used in two 5 × 5 Latin square experiments to evaluate the sparing of methionine by alternative sources of methyl groups (betaine or choline). Steers were housed in metabolism crates and limit fed ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Tsien, W.S.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1960)
    Twenty Hereford steer calves were divided as equally as possible on the basis of weight and conformation into two lots of 10 animals each. The average daily rations are shown in Table 22 for the wintering and fattening ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1961)
    In previous tests where grain intake was held at the same level, finely ground pelleted sorghum grain has produced larger and more efficient grain than rolled sorghum grain. This test was conducted to study the value of ...
  • Richardson, D.; Smith, E.F.; Koch, B.A.; Tsien, W.S.; Boren, Fred W. (Kansas Agricultural Experiment Station, 1960)
    This is a progress report of another test to further evaluate methods of sorghum grain preparation. Twenty of the heaviest steer calves purchased for experimental work were divided into two lots of 10 animals each. The ...
  • Cox, R.F.; Smith, E.F. (Kansas Agricultural Experiment Station, 1951)
    A great deal of interest in rolled grain has been expressed. Some commercial feeders have purchased rollers in preference to grinders; a few feeders truck grain to town to have it rolled in preference to grinding grain at ...
  • Nestler, Josefine; Liu, Sanzhen; Wen, Tsui-Jung; Paschold, Anja; Marcon, Caroline; Tang, Ho Man; Li, Delin; Li, Li; Meeley, Robert B.; Sakai, Hajime; Bruce, Wesley; Schnable, Patrick S.; Hochholdinger, Frank (2014)
    Root hairs are instrumental for nutrient uptake in monocot cereals. The maize (Zea mays L.) roothairless5 (rth5) mutant displays defects in root hair initiation and elongation manifested by a reduced density and length of ...
  • Su, Kemin; Bremer, Dale J.; Keeley, Steven J.; Fry, Jack D. (2008)
    Drought stress is common among cool-season turfgrasses during summer in the U.S. transition zone. A two-year field study was conducted near Manhattan, Kansas, USA, to evaluate rooting characteristics and effects of drought ...
  • Shuey, S.A.; Brandt, Robert T., Jr.; Gramlich, S.M.; Milton, C.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    Roughage level and method of corn processing were evaluated for the propensity to cause subacute acidosis in a controlled acidosis challenge model. Four ruminally fistulated steers were adapted to a high grain diet, ...
  • Milton, C.T.; Brandt, Robert T., Jr.; Shuey, S.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    Two trials were conducted to evaluate roughage levels in whole shelled-corn finishing diets and to compare use of self-feeders to a total mixed ration in a whole corn program. In trial 1, steers were fed whole corn ...
  • Jones, S.Q.; Marston, T.T.; Kraus, T.J.; DeRouchey, Joel M.; Waggoner, Justin W.; Breiner, Ryan M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Many factors affect forage quality, including moisture level at baling, compaction, bulk density, and maturity at harvest. Losses of dry matter and nutrient value occur during field curing. Hay baled at or above 18% ...
  • Jones, S.Q.; Marston, T.T.; Kraus, T.J.; DeRouchey, Joel M.; Waggoner, Justin W.; Breiner, Ryan M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010)
    Nutritionists and producers often assume that ingredients in a total mixed ration are uniformly mixed. However, many factors may affect ration homogeneity, including particle size, shape, and density and mixer discharge ...
  • 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 ...
  • Busby, W.D.; Corah, L.R.; McKee, M.; Fink, G.; Pope, Ronald V. (Kansas State University. Agricultural Experiment Station, 1980)
    Seventy-six Polled Hereford and percentage Simmental calves were used to evaluate Rumensin and drylot vs. pasture systems by average daily gain of early-weaned (54 day old) calves. Rumensin was fed at 10 g/ton of feed for ...
  • Kube, J.C.; Frey, R.A.; Shirley, John E. (Kansas Agricultural Experiment Station, 1987)
    Two Holstein cows were fed Rumensin for 12 weeks, beginning approximately 90 days postpartum. Milk production increased 7%, whereas percentage fat in milk decreased 10.3%. Percentage protein in milk increased 9.6% in ...
  • 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 ...
  • Montgomery, Sean P.; Farran, T.B.; Sindt, J.J.; Coetzer, C.M.; Pike, J.N.; Trater, A.M.; LaBrune, H.J.; Hunter, R.D.; Laudert, S.B.; Drouillard, James S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Five hundred seventy-two crossbred beef heifers were used to compare gain and feed efficiency of cattle consuming restricted quantities of energy-dense growing diets containing varying concentrations of Rumensin® and ...
  • Candler, K.C.; Awawdeh, M.S.; Gnad, D.P.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Fermentation of dietary protein in the rumen leads to ammonia absorption, which could impair amino acid utilization in cattle. Our study was conducted to determine the effects of rumen ammonia load on histidine utilization. ...
  • Wessels, R.H.; Titgemeyer, Evan C.; St. Jean, G. (Kansas Agricultural Experiment Station, 1994)
    A trial was conducted to investigate the effect of lasalocid (Bovatec®) on ruminal degradation of dietary protein in Holstein steers. Five ruminally and duodenally cannulated steers (305 kg) were fed a corn-alfalfaso ...
  • Robinson, J.B.; Ames, D.R.; Nichols, David A. (Kansas State University. Agricultural Experiment Station, 1982)
    Two trials were conducted to determine the effects of Rumensin in cold-stressed cattle. Steers fed diets with and without Rumensin were exposed to cold stress (0 C) and thermoneutrality (20 C). Rumen volatile fatty acids ...
  • 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 ...
