  • 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 ...
  • Murphy, James P.; Harner, Joseph P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    As the demand grows for cleaner water, feedlots will need to reduce and control the nutrient and sediment loading of runoff. Existing confined feedlots will need to evaluate their runoff potential. Costs of controlling ...
  • Harner, Joseph P.; Murphy, James P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    A recent water quality survey assessment found nonpoint source pollution problems in a majority of Kansas surface waters - 85% of the monitoring sites were impaired by nutrients, 60% of the sites by bacteria, 55% by ...
  • Makandar, Ragiba; Nalam, Vamsi J.; Lee, Hyeonju; Trick, Harold N.; Dong, Yanhong; Shah, Jyoti (2012)
    Fusarium head blight (FHB) is a destructive disease of cereal crops such as wheat and barley. Previously, expression in wheat of the Arabidopsis NPR1 gene (AtNPR1), which encodes a key regulator of salicylic acid (SA) ...
  • Schmidt, D.G.; Gnad, D.P.; Sargeant, J.M.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Salmonella dublin is a bacterium that can have devastating effects in dairy herds. It is most deadly with calves that range in age from 10 days to 5 months. Salmonella dublin is shed from carrier animals through feces, ...
  • Wendelburg, J.W.; Lambert, D.L.; Thippareddi, H.; Kastner, Curtis L.; Phebus, Randall K.; Marsden, James L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Prime rib is generally prepared by cooking to low temperatures for long times to attain the desired tenderness and juiciness. Destruction of Salmonella spp. in blade tenderized prime rib was examined by following ...
  • Koch, B.A.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1975)
    Two feeding trials involving 118 finishing Pigs were conducted to determine minimum salt needed in finishing diets. Performance of pigs fed 0.2 to 0.5% salt diets did not differ significantly, but pigs fed 0.1% or no ...
  • Hix, E.L.; Bell, T.D.; Parrish, D.B.; Good, A.L. (Kansas Agricultural Experiment Station, 1952)
    The consumption of salt by herbivorous animals in general, and their apparent relish for salt, have been recognized for many years, but its importance may be questioned by many because of lack of knowledge of both the ...
  • Park, A.F.; Smith, J.F.; Rozell, Timothy G.; Stevenson, Jeffrey S.; Shirley, John E.; Scheffel, Michael V. (Kansas Agricultural Experiment Station and Cooperative Extension Service., 1998)
    Representative MUN values can be obtained by testing a milk sample before milking, at AM or PM milking, or with an in-line siphon sampling device. MUN values obtained from homogenous milking strings are as accurate ...
