  • Tan, Z.; Chengappa, M. M.; Nagaraja, T. G. (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 ...
  • Vanzant, E.S.; Cochran, R.C.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Four winter protein supplementation schemes were studied using 116 beef cows grazing Flint Hills range. The treatments were: 1) 4.0 lb soybean meal/sorghum grain (27.3% crude protein (CP» per head daily (SS), 2) 4.0 lb ...
  • Schalles, R.R.; Martin, L.C.; Zoellner, K.O. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    In a computer simulation based on KSU data, cattle bred and managed to be moved directly from weaning to feedlot and slaughtered at a young age produced the greatest profit. Cattle that were too small or too large and ...
  • Towne, G.; Beharka, A.B.; Nagaraja, T. G. (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 ...
  • Garten, Carl H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Individual large round bales of sudan hay from the same cutting and field ranged from 1,525 to 6,250 ppm nitrate (NO3 ), with an average of 2,764 ppm. These results illustrate the substantial variability that can occur ...
  • Brazle, F.K.; Kuhl, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Growing steers were limit-fed the same amount of a grain- and silage-based ration either in drylot or on dormant native range. The steers wintered on pasture gained 14.2% slower (1.82 V5 2.08 lb/d; P<.01) and were 15.3% ...
  • Apple, J.K.; Cundiff, L.V.; Wise, J.W.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Hot carcasses from 288 steers were used to develop equations to predict weights and percentages of trimmed retail cuts. and trimmable fat yields from hot carcass traits. Independent variables examined were: (1) 12-13th ...
  • Cundiff, L.V.; Koch, R.M.; Gregory, K.E.; Crouse, J.D.; Dikeman, Michael E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Preliminary data representing two of five calf crops in Cycle IV of the Germ Plasm Evaluation Program are reported. Carcass and meat data from 454 steers produced by mating 11 sire breeds to Hereford and Angus dams were ...
  • Marston, T.T.; Simms, D.D.; Schalles, R.R.; Zoellner, K.O.; Martin, L.C.; Fink, G.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Spring and fall calving Angus (n==86) and Simmental (n==96) cows at three different locations in Kansas were used to evaluate the relationships between milk production, Milk Expected Progeny Difference (Milk EPD), and ...
  • Schalles, R.R.; Ward, B.J.; Zoellner, K.O.; Martin, L.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Weights. frame scores. scrotal circumferences, and prices of bulls increased significantly over 17 years. Angus had the greatest increase in birth weight, average daily gain (ADG) during test, adjusted yearling weight, ...
  • Brandt, Robert T., Jr.; Kuhl, G.L.; Freeman, A.S.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    One hundred forty crossbred yearling steers (815 lb) were utilized to evaluate grain type (steam flaked com vs steam flaked milo) and supplemental fat (O or 4% yellow grease) on finishing performance. There were no ...
  • Corah, L.R.; Brazle, F.K.; Blecha, Frank; Reddy, P.G.; Wary, R.E. Jr.; Klindt, J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Steers previously fed high-endophyte fescue hay showed a greater response of Ralgro® implants than those fed a low-endophyte hay. The mode of action for this response was not explained by cellular immune system responses ...
  • Brazle, F.K.; Coffey, K.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Stocker heifers were fed diets of either 67% rice mill feed + 33 % dehydrated alfalfa pellets (RA) or a 67% grain sorghum + 33% dehydrated alfalfa pellets (GA). The RA heifers consumed more feed daily but gained slower ...
  • Kuhl, G.L.; Shroyes, J.P.; Hartman, Paul D.; Fjell, Dale L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Nine summer annual forages were studied to evaluate yield and nutritional quality differences resulting from forage type and cultivar when cut at two stages of maturity. Substantial dry matter yield and quality differences ...
