  • Managing beef genotypes for profit: a computer simulation
    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 ...
  • 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 ...
