  • Harmon, D.L.; Nagaraja, T. G. (Kansas Agricultural Experiment Station, 1986)
    The ruminant animal has the unique advantage of microbial digestion in the rumen. This relationship between host animal and microbial population presents some unique advantages and disadvantages to the animal in terms ...
  • Jeon, I.J. (Kansas Agricultural Experiment Station, 1988)
    One of the common and important off-flavors in milk is hydrolytic rancidity or lipolyzed flavor. The rancidity results from hydrolytic cleavage of fatty acids from milk fat by the enzyme lipase and their release as free ...
  • Heikes, K. (Kansas Agricultural Experiment Station, 1989)
    The July 1989 USDA Sire Summary introduced a new system for genetic evaluations in dairy cattle. These evaluations, known as the Animal Model (AM), include several new features that help to increase the accuracy of ...
  • Park, A.F.; DeFrain, J.M.; Titgemeyer, Evan C.; Ferdinand, E.E; Cochran, R.C.; Schmidt, D.G.; Ives, S.E.; Nagaraja, T. G.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    Four-ruminally fistulated, multiparous, pregnant Holstein cows were studied to characterize ruminal adaptations during the transition from gestation to lactation. Cows were fed typical far-off and close-up diets, a late ...
  • Park, A.F.; Titgemeyer, Evan C.; Cochran, R.C.; DeFrain, J.M.; Ferdinand, E.E.; Wallace, N.; Nagaraja, T. G.; Johnson, D.E.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    We used four ruminally fistulated, multiparous, pregnant Holstein cows to delineate microbial adaptations in dairy cows as they experienced the transition from one lactation to the next. Diets consisted of typical ...
  • Herald, T. J.; Schmidt, Karen A. (Kansas Agricultural Experiment Station and Cooperative Extension Service, 1999)
    The change in textural quality of cheese during frozen storage is of concern to the frozen food industry. Many food products such as frozen pizza and dinner entrees are stored at !0.5EF or below for extended periods ...
  • Park, A.F.; Titgemeyer, Evan C.; Cochran, R.C.; DeFrain, J.M.; Ferdinand, E.E.; Nagaraja, T. G.; Johnson, D.E.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Four-ruminally fistulated, multiparous, pregnant Holstein cows were used to delineate changes in ruminal fermentation in dairy cows as they experienced the transition from one lactation to the next. Diets consisted of ...
  • Harner, Joseph P.; Smith, J.F.; Millner, R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    The first low-profile cross-ventilated (LPCV) freestall building was stocked in fall 2005 in North Dakota. There currently are 3 other LPVC freestalls operational and 6 others under construction. The LPCV building offers ...
  • Roberson, J.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    Mastitis is considered the most costly disease in the U.S. dairy industry. Treatment of clinical mastitis is the major reason for antibiotic contamination of products on U.S. dairy farms. A survey of 183 dairy producers ...
  • Ferdinand, E.E.; Titgemeyer, Evan C.; DeFrain, J.M.; Park, A.F.; Johnson, D.E.; Ethington, R.T.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a ...
  • Burgos, V.; Titgemeyer, Evan C.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Forty-eight primiparous Holstein cows were used in two simultaneous 3×3 Latin squares with 28-day periods to evaluate expeller soybean meal from three sources. Six pens containing eight cows each were utilized. Cows were ...
  • Miller, W.F.; Titgemeyer, Evan C.; Scheffel, Michael V.; Ethington, R.T.; Shirley, John E.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    We used 24 multiparous Holstein cows in 4 × 4 Latin square design to evaluate full-fat corn germ as a replacement for whole cottonseed and tallow in total mixed diets for lactating dairy cows. Experimental diets on a ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1985)
    A comparison was made of the AM-PM production testing program with the traditional DHI program during 13 test periods of 1984 in the KSU Dairy Teaching and Research Center herd. Although there were slight variations in ...
  • Bortone, E.J.; Daccarett, M. G.; Morrill, J.L.; Feyerherm, A.M.; Shirley, John E. (Kansas Agricultural Experiment Station, 1990)
    One hundred and ten Holstein heifers from the KSU Dairy Research Unit were used in this experiment. They were fed either 100% (control) or 115% (enhanced) of NRC requirements for energy, protein, major minerals, and ...
  • Daccarett, M. G.; Morrill, J.L. (Kansas Agricultural Experiment Station, 1989)
    One hundred and one Holstein heifers from the KSU Dairy Unit were used in this experiment. They were assigned to two treatments in which they were fed either 100% or 115% of the 1988 NRC requirements of energy, protein, ...
  • Miller, W.F.; Titgemeyer, Evan C.; Park, A.F.; Burgos, M.V.; Hammond, A.K.; Scheffel, Michael V.; Shirley, John E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
